Cross-launching from the TrueSight console to TrueSight IT Data Analytics

In the search query syntax, the following definitions apply:

• HostName1 and HostName2 refer to the various host names associated with the application node.
• ApplicationName refers to the name of the application.

By default, the search query displays a list of host names (corresponding to the devices) associated with the application.

If you have a large number of devices included in the application, then the default search query can be very long because it will have a large number of host names. Instead of searching for a list of host names to find event data associated with those hosts, you can search for the application context.

To be able to search by the application context, you need to perform the following steps in TrueSight IT Data Analytics:

1. Navigate to BMC_ITDA_HOME%\custom\conf\server.
2. Edit the olaengineCustomConfig.properties file and locate the console.crosslaunch.type=host property.
3. Change the property value from host to app. 
4. While creating data collectors for each of the devices (hosts) associated with the application, add a tag named ApplicationContext with the tag value set to the application name. For more information, see Creating data collectors in Log Analytics. .

Performing the preceding steps in TrueSight IT Data Analytics is optional, however, this can be useful to simplify the search query.

Accessing TrueSight IT Data Analytics from an event directly associated with the application is similar to accessing TrueSight IT Data Analytics from an application because an application level event is associated with a group of hosts or devices and not with a specific device or host. Therefore, use the same search query parameters that are used for cross-launching from an application. For search query parameters, see the search query and notes on accessing Log Analytics from an application.
