Save the HTTP destination details. 2.9 Set Up the Connection to the Syslog Server The syslog client must be configured so that it can connect to the internal syslog server in SAP HANA Smart Data Streaming. Each infrastructure, such as syslog-ng or rsyslog, has its own configuration mechanism. Whatever the syslog client, it must be configured in such a way that it can send events to the streaming host on the configured port using either UDP or TCP. The configuration format is TIMESTAMP EVENTSOURCE MESSAGE. Example You might define this for syslog-ng based on the following template for the destination: destination syslogdest { tcp("<your streaming host>" port(<your listening port on the streaming port>) time_zone("+00:00") template("$s_date $HOST $MSG\n")); }; Installation and Configuration 2015 SAP SE or an SAP affiliate company. All rights reserved. 17

18 The default port is 1515, but you can use a different port if required. The log events are sent in UTC, independent of the local time zone configured on the host of the syslog client. 1. On the Smart Data Streaming host, you add the following lines to the file /etc/syslog-ng/syslogng.conf: Sample Code destination itoasyslogdest { tcp("localhost" port(1515) time_zone("+00:00") template("$s_date $HOST $MSG\n")); }; log { source(src); destination(itoasyslogdest); }; The host is "localhost" in this example because the syslog client and SAP HANA Smart Data Streaming are on the same host. However, the host is not restricted to this value. A syslog client on another host can also be configured to send syslog events to SAP IT Operations Analytics. 2. You restart the syslog-ng service Start the Syslog Server Starting the internal syslog server triggers the streaming of syslog events into SAP IT Operations Analytics. You do not need to start the streaming project separately. Prerequisites The Web service provider provides an API to deploy, start and stop the streaming project and the syslog adapter. It must be started before the syslog server can be started. The ODBC Data Source has been configured with [hanaservice]. For more information, see the SAP HANA Smart Data Streaming: Configuration and Administration Guide. The <sid>adm user has started the Web service provider in the $STREAMING_HOME/wsp directory, for example, with./wsp.sh &. If you first logged on with another account such as the root user, make sure you switch to <sid>adm using su - <sid>adm (the hyphen will ensure that the environment variables for this user are set) and specify the correct password for this user. Procedure 1. As the administrator for SAP IT Operations Analytics, log on to core. 2. Choose the default bucket to open it. 3. Choose the Edit Bucket button (top right) SAP SE or an SAP affiliate company. All rights reserved. Installation and Configuration

19 4. In the Syslog Server window, specify the following: Table 2: Field Port of Syslog Server Description This port is used for the connection from the syslog client to the internal syslog server in SAP HANA Smart Data Streaming. This is the same port as the one you specified in the syslog client when setting up the connection to the syslog server. Communication Protocol Data Service Name UDP or TCP This data service is used for the connection from the output adapter in SAP HANA Smart Data Streaming to SAP HANA. The data service provided with the syslog input adapter is itoa_service. 5. Choose Start. Installation and Configuration 2015 SAP SE or an SAP affiliate company. All rights reserved. 19
