6 Idea Solution and Scenario Provide a system programmer with the means to get immediately notified when an important event occurs to check major system indicators to decide whether the event requires immediate attention Solution Mobile app which receives event notifications z/os back end to send events and manage participants 1. System Programmer/Administrator: Not at workplace 2. Event happens on mainframe, e.g. Defined Capacity Limit reached or performance stalls 3. Alert is generated by MPF, CPM, RMF, SA etc and send via push notification to mobile phone 4. Solution allows to check back status/additional information from mobile phone to mainframe 5. Then take action (at workplace) or classify status as uncritical 6

15 zevent App Startup Start: Splash Screen Events: Always shown after Startup Settings: Show/Hide Tabs Connect to Push Server Connect to Monitors 15

16 zevent Registration ❶ The first required step is to connect to the push server ❷ Connection information can be provided by a QR code which can also be created by the Mobile App ❸ After scanning the QR code, the connection information is filled into the push settings display ❹ Pressing the Connect button sends a message to the push server to retrieve the authentication key ❺ The key is also displayed in the settings dialog 16

17 zevent Push Server Connection ❺ Registration is required when the application is installed and used for the first time and after each re-install ❻ The application checks whether the registration key has changed and if yes it provides a dialog to send the authentication information to the system administrator ❼ The user can select the program and the connection information is entered in JSON format ❽ After pressing the SEND button the information is on its way 17

18 Tabs and Dialogs Events For the first time Filled with events Pressing on an event allows to display message details Pressing on the details shows a pop-up dialog to go to RMF, z/osmf RM or to delete the events 18

19 Tabs and Dialogs Tab Selection The Events tab is the main tab and it is always present All other tabs can be configured based on need and functions which should be exploited Snapshot: to display graphical information which also receives as push notifications RMF: accesses the RMF data portal to display RMF performance data z/osmf RM: accesses z/osmf to display RMF performance data Note: The information on RMF and z/osmf can be redundant and the option is simply provided as a user s choice 19

20 Tabs and Dialogs Snapshot Snapshots are performance information which are displayed as graphical charts Provide important analysis information immediately with an important event on a regularly basis without requesting the user to pull the information The usage is the same as on the Events tab: The occurrence of a snapshot or chart is signaled as an event Clicking on the event displays the chart A chart can be manipulated (zooming) or deleted 20

21 Snapshot The Idea Key metrics on the z/os systems are monitored continuously by the zevent provider The provider maintains a chart document in JSON format The values are retrieved for each interval and appended to the chart A push message with the chart as payload is sent to the zevent app The App receives the JSON document and visualizes the chart graphically The user of the zevent app is instantly notified and can analyze the metric trend {"registration_ids" : ["APA91bEEaqiSVnuSNZjwrfCK0WWvb28RpCJn _nlwommuej0lqwejhkwa3lgl1glpc8x5kn7vj1yttu43s2j0fnwsdajlq7fs p9qiba_nsguuxwlft1fjn4cldq6gccutmcjkieytwk2a"],"data" : {"ch arts" : [{"sys" : "SYS2","time" : "17:53:44","title" :"CPU C onsumption","xaxis" : {"title" : "Time (h)","label" : [1,2,3,4,5,6,7,8,9,10,11]},"yaxis" : {"title" : "MSU"},"series": [ {"title" :"CPU1","type" :"Lines","markers":false,"color" :"# A","values" :[17,22,17,21,4,21,8,5,1,6,21]},{"tit le" :"CPU2","type" :"Lines","markers":false,"color" :"#6 6A48E24","values" :[24,29,20,15,21,30,6,17,28,18,9]}],"usr" {"Date":"15/04/28","Time":"17:30:00"}}]}}. 21

22 Tabs and Dialogs RMF & z/osmf RMF and z/osmf allow the mobile user to logon to the z/os system and to obtain additional information to further analyze a performance event RMF accesses the RMF performance data portal z/osmf accesses z/osmf RM 22

23 zevent RMF Performance Data Portal The RMF Performance Data Portal appears on the RMF tab when the following URL is specified with the connection profile: From the primary screen the user can now navigate to any preferred metric 23

24 zevent z/osmf Resource Monitoring The z/osmf Resource Monitoring Dashboard list is displayed on the z/osmf tab when the following URL is specified with the connection profile: The user can now open the preferred Dashboard 24

25 Tabs and Dialogs Connection In order to access the z/os system it is necessary to provide A free selectable label The URL for RMF resp. z/osmf Timeout value in milliseconds Userid and password 25

26 Tabs and Dialogs Connect A connection can be established by the mobile user Pressing the connection entry and then Connect The mobile device accesses the z/os system If the connection succeeds the connection entry is displayed in green (if not in red) A connection can also be established under the cover from an event or snapshot entry for the system from which the event or snapshot was sent Assuming a connection entry is defined for that system 26
