7 1. Products Overview: Server Management Manager & Server Management Agent Server Management Manager and Server Management Agent are software packages for server management aimed at the stable operation and the efficient management of servers. This software tracks configuration information and operation statuses of the server resources, detects server failures, and reports the alert to the system administrator, to prevent or quickly respond to such failures. Importance of server management To ensure stable server operations, you need to reduce the workload for server management personnel. Stable server operations Server shutdowns directly lead to a loss of your business opportunities and profits. Therefore, you always need to ensure complete operations. In case of a server failure, you will have to notice it as early as possible to track down the cause and take necessary measures. If you quickly recover the system from the failure, you ll be able to minimize profit (cost) losses. Reduction of the workload for server management It takes a large workforce to manage servers, especially in a large system or when using servers in a remote location. Reduction of the workload for server management leads to cost reduction. What are Server Management Manager and Server Management Agent? Server Management Manager and Server Management Agent are server management software packages that manage and monitor servers on the network. If you introduce this software, you will be able to obtain/manage/monitor information on configuration, performance, and failures. In addition, you will be able to notice a failure by notification from the reporting function on a real-time basis. Effectiveness of Server Management Manager and Server Management Agent Server Management Manager and Server Management Agent are very effective for various needs within a system environment that is getting increasingly diversified and complicated. Detection of server failures Server Management Agent collects a variety of failure information and checks system statuses. When it detects an abnormality, it reports the alert to Server Management Manager. Prevention of server failures Server Management Agent supports a preventive maintenance function that predicts failure occurrences. Central management of distributed servers Server Management Manager offers GUI interfaces that allow you to efficiently manage servers distributed on a network

8 1.1. Detection of Server Failures Server Management Manager and Server Management Agent detect an abnormality that can lead to a failure at an early stage and send failure information to the administrator immediately. In case of a failure, Server Management Agent detects it and reports the alert to Server Management Manager. Then, Server Management Manager displays the received alert in the Alert Viewer and changes the status colors of the server or its components so that you can identify the failure location at a glance. Furthermore, you can respond to failures quickly by referring to the description of the failures and the appropriate actions

9 1.2. Management of Server Operating Statuses Server Management Agent manages and monitors various server components. You can use Server Management Manager s Data Viewer to access information that is managed and monitored by Server Management Agent

10 1.3. Central Management of Distributed Servers Server Management Manager provides outstanding GUIs to centrally manage distributed servers on the network. Its Explorer-style screen displays components in a hierarchical manner so that you can manage servers efficiently. Central management of servers To manage servers, Server Management Manager uses the following types of GUIs: Operation Window It creates and manages a map of servers connected on a network. You can make hierarchical maps based on setup locations, organizations, or purposes. DataViewer It displays server resource components in an Explorer style. It changes the status colors of abnormal server components so that you can easily identify failure locations. Alert Viewer It manages failure alerts from all servers in a unified manner. It receives alerts immediately when a failure occurs in a server so that you can notice any failure on the network instantaneously

20 3. Monitoring Functions This section explains the monitoring function that Server Management Agent offers. To change the setting of each monitoring function, use the Control Panel (ESMagntconf). Method of starting the Control Panel (ESMagntconf) On VMware, execute the following command and change the value of the LANG environment variable temporarily before starting the Control Panel (ESMagntconf). # export LANG=en_US 1. Log in to the system as the root user. 2. Move to the directory where Server Management Agent is installed. # cd /opt/nec/esmpro_sa 3. Move to the directory where ESMagntconf is stored. # cd bin 4. Start the Control Panel (ESMagntconf). #./ESMagntconf

21 3.1. General Properties Settings From the [General Properties] screen, you can set the following information. To display the [General Properties] screen, select "General" on the Control Panel (ESMagntconf). Enable the Manager to modify SNMP Setting "Enable the Manager to modify SNMP Setting" specifies whether the Server Management Manager can modify server operation parameters via SNMP. When checked, it is enabled. When not checked, it is disabled. (Set using the space key.) SNMP Community Select the community name that Server Management Agent uses to collect information on the local machine. The community name displayed in the list is the community name registered in SNMP environmental configuration file (snmpd.conf). (Select using the "UP/DOWN" arrow keys.) Select a community name that has the privilege to read from localhost. Rack Name The rack name can be set when the server is a rack mount type. It is possible to manage each rack by setting the rack name. The maximum length of the rack name is 63 characters, and you can use A-Z, a-z, 0-9, '.', '_' or '-'

22 3.2. CPU Load Monitoring Functions When Server Management Agent detects a high-loaded CPU, it will issue a message to the syslog and will report the alert to Server Management Manager. With Server Management Manager s DataViewer, you can check which CPU has unusual usage. Since the function monitors load statuses either by individual CPUs or CPU total, you can monitor a server as one package regardless of the individual CPUs. Settings From the [CPU Load] screen, you can set the following information. To display the [CPU Load] screen, select "CPU" on the Control Panel (ESMagntconf). CPU load monitoring is not performed at the default settings. If you need to monitor the CPU load, change the settings to perform monitoring. You do not have to change threshold values of the CPU load rates. Although you may specify any values, the threshold values near the current values could cause the Agent to issue alerts frequently. When you change CPU load values, be careful not to cause alerts to be issued frequently due to the setting of the values. Sample Interval(s) Specify the CPU load monitoring cycle. Sample Interval can be set to 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, or 60 seconds. (Select using the "UP/DOWN" arrow keys.) The default value is 10 seconds. Utilization Rate Specify the Utilization Rate of the CPU load monitoring. Utilization Rate can be set to load for 1 min, 5 min, 30 min, 1 hour, 1 day, or 1 week. (Select using the "UP/DOWN" arrow keys.) The default value is 1 minute. CPU s Item Select the CPU (individual or total CPU) for which you want to set the threshold. (Select using the "UP/DOWN" arrow keys.) Enable Threshold To enable the monitoring function of the CPU load factor, check this field. (Set using the space key.) The threshold can only be set when checked

23 Threshold Set the warning and fatal thresholds. The default values of warning and fatal thresholds are as follows. Monitoring Item Fatal(Report) Fatal(Reset) Warning(Report) Warning(Reset) CPU load factor (%) Fatal: The Report field specifies the high CPU load limit that generates a Fatal alert. The Fatal alert is reset when the CPU load decreases to lower than the threshold in the Reset field. Warning: This is similar to the Fatal fields, except a warning alert is generated or reset. When the CPU load exceeds the amount in the Report field, a Warning alert is generated. The Warning alert is reset when the CPU load decreases to lower than the threshold in the Reset field

24 3.3. Syslog Monitoring Functions Server Management Agent monitors, based on the key word, a monitoring event logged to syslog and then reports the content of the event to Server Management Manager. You can add new event sources and monitoring events and delete unnecessary event sources and monitoring events, according to the system environment. Server Management Agent can monitor the messages logged into syslog by other applications and report the messages to Server Management Manager. Settings From the [Syslog Properties] screen, you can set the following information. To display the [Syslog Properties] screen, select "Syslog" on the Control Panel (ESMagntconf). Refer to "4.5. Syslog Event Setting" for how to add/delete syslog monitoring events. Server Management Agent monitors the syslog "/var/log/messages. Monitor Interval Specify the monitoring interval of Syslog event monitoring. The range is 10 to 3600 seconds. The default value is 300 seconds

25 3.4. Storage Monitoring Functions Server Management Agent prevents some possible troubles by using the function "Hard disk prefailure prediction." "Hard disk prefailure prediction" judges whether there might be a problem if you continue to use the hard disk. When some problems are detected, it will issue a message to the syslog and will report the alert to Server Management Manager. Because the failing hard disk, where the error incidence is high, can be recognized before the hard disk actually breaks down, you can do a preventive exchange. Server Management supports "Hard disk prefailure prediction" using S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology). S.M.A.R.T. is a function used by a hard disk to monitor several items by itself. A hard disk gives an alert to Server Management Manager when the hard disk itself predicts a potential serious problem. 1) Only a single hard disk is monitored. 2) The storage devices that are not the SCSI/IDE connections are not monitored, such as USB. 3) The storage monitoring is not supported when the OS or HDD device does not support a S.M.A.R.T function. Settings From the [Storage Properties] screen, you can change the Sample Interval of Storage Monitoring Service, mode of hard disk prefailure prediction function, and can reset the status of an exchanged hard disk. To display the [Storage Properties] screen, select "Storage" on the Control Panel (ESMagntconf). Sample Interval(s) Specify the Sample Interval. The range is 1 to 3600 seconds. The default value is 60 seconds. When you click [Default], the Sample Interval will be set to the default value

26 HD Prefailure Prediction To enable the monitoring function of the HD Prefailure Prediction, check this field. (Set using the space key.) This field is checked by default. You cannot set the mode of each hard disk individually. All hard disks work in the same mode with the mode of hard disk prefailure prediction turned on or off. Reset Status Device (HD) Select a hard disk that needs to be reset. (Select using the "UP/DOWN" arrow keys.) [Reset Status] Reset the status information of the hard disk selected in "Device (HD). (For instance, use this button when you exchange hard disks.) When you replace a hard disk, you have to reset the status information to monitor the new disk. The procedure for adding a storage monitoring device Server Management Agent supports storage monitoring. The following are the main functions of storage monitoring. Management of configuration information for the storage devices connected to SCSI or IDE. Hard Disk, CD-ROM, a TAPE device, an optical memory device, etc., are contained in a storage device. By default, these storage monitoring functions manage the devices that can be identified as IDE devices by the OS. If you want to add the other devices to the management object of storage monitoring, you must change the setting of the management object. Refer to the following process. 1. Investigate the device driver name of the SCSI or IDE controller connected with the storage devices that you want to manage. 2. Execute the following command to stop ESMstrg service: # /etc/init.d/esmstrg stop 3. Open the following file using vi command, etc. /opt/nec/esmpro_sa/data/storage.inf

27 4. Add the device driver name (you investigated in step 1) to the [Management Port] section in "storage.inf" For example In the case of adding the adp94xx driver. [Management Port] [Management Port] adp94xx 5. Add the device driver name to the [Diagnostic Port] section. 6. Close the "storage.inf. 7. Execute the following command to start ESMstrg service: # /etc/init.d/esmstrg start 8. Check the below items. "ESMstrg" has started normally. The additional devices wanted for monitoring are displayed in DataViewer. In case the monitoring device is a hard disk, the "Status" item displays "Device is Normal" on the [HardDisk] - [General] Information View in DataViewer

28 3.5. File System Monitoring Functions This function monitors the file system s free space based on the free disk space (MB). When Server Management Agent detects space shortages, it will issue a message to the syslog and report the alert to Server Management Manager. With the Server Management Manager s DataViewer, you can check which drive is short of free space. Settings From the [File System] screen, you can set the following information. To display the [File System] screen, select "File System" on the Control Panel (ESMagntconf). 1) This function only monitors the file system on a local hard disk (directly connected to the server). 2) You cannot monitor the network drives and the file system on removable drives (such as CD-ROMs). 3) You cannot monitor a file system of less than 100 MB. Sample Interval(s) Specify the Sample Interval. The range is 1 to 3600 seconds. The default value is 60 seconds. When you click [Default], the Sample Interval will be set to the default value. Filesystem Select a Filesystem to change threshold and/or monitoring mode. (Select using the "UP/DOWN" arrow keys.) Disable Threshold When checked, the free space of the file system is not monitored. (Set using the space key.) Enable Threshold (The amount of free bytes) When checked, the free space of the file system is monitored. (Set using the space key.) The threshold can only be set when checked. This field is checked by default. Threshold Set the warning and fatal thresholds. The default values of warning and fatal thresholds are as follows. When you click [Default], the thresholds will be set to default values. Monitoring Item Fatal Warning Free space (unit: MB) 1 percent of the capacity 10 percent of the capacity

29

30 3.6. Network (LAN) Monitoring Functions If there are many abandoned or error packets during a unit time (monitoring interval), the LAN monitoring function will determine that some failure has occurred in the network, issue a message to the syslog, and report the alert to Server Management Manager. The function checks LAN-related failures based on its percentage in relation to all packets sent/received during a monitoring interval. Therefore, there is a possibility that a message is registered due to a temporary increase in load. However, if such a condition is recovered immediately, there will be no problem. If it is not recovered immediately or such failures occur frequently, check the network environment including hardware and distribute the load. After Server Management Agent Ver4.3, the LAN monitoring function is not supported. Before Ver4.2, the default setting of LAN monitoring function is off. If you want to monitor the LAN devices, you must change the setting of ESMlan daemon. Refer to the following process. 1. Execute the following command and set up so that the ESMlan service starts automatically. # /sbin/chkconfig ESMlan on 2. Start ESMlan service. # /etc/init.d/esmlan start When you disable network (LAN) monitor setting, please carry out the following procedures. 1. Execute the following command so that the ESMlan service starts not automatically. # /sbin/chkconfig ESMlan off 2. Execute the following command # /etc/init.d/esmlan stop Settings From the [LAN Properties] screen, you can set the following information. To display the [LAN Properties] screen, select "LAN" on the Control Panel (ESMagntconf). Sample Interval(s) Specify the Sample Interval. The range is 1 to 3600 seconds. The default value is 180 seconds. Network Hardware Error (%) Specify the threshold of the percentage of Network Hardware Error in total transmission and reception packets per monitoring cycle. Specify 0 when you want a report as soon as the error is detected. When the network cable is pulled out or the HUB power switch is off, a Network Hardware error occurs. Each error occurs for the following reasons

31 Error Reason Alignment Errors Broken packets for collision FCS Errors Broken packets for collision Carrier Sense Errors Cable disconnected, Cable defect, or Transceiver defect The range is 0 to 100 percent. The default value is 50 percent. Transmission Retry (%) Specify the threshold of the percentage of collision and delay packets in total transmission packets per monitoring cycle. Transmission Retry will occur when the server is under the high network load. The range is 10 to 50 percent. The default value is 35 percent. Transmission Abort (%) Specify the threshold of the percentage of packets disposed due to excess collisions errors, etc., in total transmission packets per monitoring cycle. Transmission Abort will occur when the server is under the high network load. The range is 10 to 50 percent. The default value is 35 percent

32 Physical Memory Usage Monitoring Functions When Server Management Agent detects a shortage of memory, it will issue a message to the syslog and will report the alert to Server Management Manager. With Server Management Manager s DataViewer, you can check status of memory. Settings From the [Memory Properties] screen, you can set the following information. To display the [Memory Properties] screen, select "Memory" on the Control Panel (ESMagntconf). Physical Memory Usage monitoring is not performed at the default settings. If you need to monitor the Physical Memory Usage, change the settings to perform monitoring. You do not have to change threshold values of memory usage rate. Although you may specify any values, the threshold values near the current values could cause the Agent to issue alerts frequently. When you change a memory usage rate values, be careful not to cause alerts to be issued frequently due to the setting of the values. Sample Interval(s) Specify the Sample Interval. The default value is 150 seconds. Sample consecutive number Specify the monitoring Sample Consecutive Number. Utilization Rate can be set to 1 to 10 times. The default value is 6 times. Enable Threshold To enable the monitoring function of memory, check this field. (Set using the space key.) The threshold can only be set when checked. Threshold Set the warning and fatal thresholds. The default values of warning and fatal thresholds are as follows. Monitoring Item Fatal(%) Warning(%) Memory Usage rate(%) Fatal: Set the threshold value for the fatal status. Warning: Set the threshold value for the warning status

33 3.8. Page Fault Monitoring Functions When Server Management Agent detects a frequency of page faults, it will issue a message to the syslog and will report the alert to Server Management Manager. With Server Management Manager s DataViewer, you can check status of page fault. Page fault monitoring function does not support in VMware. Settings From the [Page Fault Properties] screen, you can set the following information. To display the [Page Fault Properties] screen, select "Page Fault" on the Control Panel (ESMagntconf). Page fault monitoring is not performed at the default settings. If you need to monitor the page fault, change the settings to perform monitoring. You do not have to change threshold values of page fault rate. Although you may specify any values, the threshold values near the current values could cause the Agent to issue alerts frequently. When you change a page fault rate values, be careful not to cause alerts to be issued frequently due to the setting of the values. Sample Interval(s) Specify the Sample Interval. The default value is 60 seconds. Sample Consecutive Number Specify the monitoring Sample Consecutive Number. Utilization Rate can be set to 1 to 10 times. The default value is 10 times. Enable Threshold To enable the page fault monitoring function, check this field. (Set using the space key.) The threshold can only be set when checked. Threshold Set the warning and fatal thresholds. The default values of warning and fatal thresholds are as follows. Monitoring Item Fatal Warning Page Fault Fatal: Set the threshold value for the fatal status. Warning: Set the threshold value for the warning status

34 4. Report Setting Function This section explains the report setting for where and when an event is to be reported. To change the report setting, use the Control Panel (ESMamsadm). Method of starting the Control Panel (ESMamsadm) On VMware, execute the following command and change the value of the LANG environment variable temporarily before starting the Control Panel (ESMamsadm). # export LANG=en_US 1. Log in to the system as the root user. 2. Move to the directory where Server Management Agent is installed. # cd /opt/nec/esmpro_sa 3. Move to the directory where ESMamsadm is stored. # cd bin 4. Start the Control Panel (ESMamsadm). #./ESMamsadm

35 4.1. Flow of Report Setting To report the alert by using SNMP as the report method When Server Management Agent was installed, the setting to report the alert by using SNMP as the report method for monitor events was almost completely established. The report preparation is completed by setting the IP address of Server Management Manager for the base setting. Refer to "Base Setting of Manager (SNMP)" for details of the setting. To report the alert by using the report methods other than SNMP 1. Perform the Base Setting. (Base Setting) Refer to "Base Setting of Manager (TCP_IP In-Band)" for the basic setting to report the alert by using TCP_IP In-Band as the report method. Refer to "Base Setting of Manager (TCP_IP Out-of-Band)" for the basic setting to report the alert by using TCP_IP Out-of-Band as the report method. 2. Set the list of report destinations. (Destination Setting) Refer to "Address Setting when Manager (TCP_IP In-Band) is used as a report method" for the address setting to report the alert by using TCP_IP In-Band as a report method. Refer to "Address Setting when Manager (TCP_IP Out-of-Band) is used as a report method" for the address setting to report the alert by using TCP_IP Out-of-Band as a report method. 3. Set monitor events and associate monitor events with report destinations. (Agent Event Setting, Syslog Event Setting) Agent Events are monitor events that Server Management Agent originally detects. Syslog Events indicate monitor events that the Syslog monitoring function detects

36 4.2.
