Summary
Mapping additional data value to ArcSight field in Logger

Products
ArcSight Logger

Environment
Logger - All versions
Connector - All versions

Situation
The process of mapping additional data value is not easy with Logger alone, but with ESM it is rather simple and straightforward.

Resolution
This is a quick example of custom mapping additional data in Logger.

a) agent ID: Need to know the agentID. The easiest way is to look in user/agent/agent.properties.

Example:
agents[0].destination[1].agentid=3qN7D14gBABCABeuJX3s4bQ\=\=

b) Device Vendor and Product: In this example, OpenText and Logger

c) The additional data fields that you want to map to ArcSight event fields. See the raw message in Logger to determine the names of the additional data fields.


1. To put this all together, you need to first create the file ngmappings.adatamappings.properties in the following directory.

current/user/agent/aup/<agent id>/fcp/custommappings/<Device Vendor>/<Device Product>

Notice that you need to replace the agent ID variable with that of the agent ID found in above a).
Possible you have to create several of these directories.

Example:
current/user/agent/aup/3qN7D14gBABCABeuJX3s4bQ==/fcp/custommappings/OpenText/Logger

2. Now you have to populate the file ngmappings.adatamappings.properties.
In this example, two fields ad.deviceowner and ad.devicehostname are to flexString1 and flexString2.

The ngmappings.adatamappings.properties file will look like this:

#ArcSight Properties File
event.flexString1=deviceowner
event.flexString2=devicehostname

3. Restart the Connector and look for values to be populated.
The following is the test result.

Raw Event which was sent to Logget which has "ad.deviceowner=Device Owner ad.devicehostname=Device Host Name":

CEF:0|OpenText|Logger|||Test Alert Event|Unknown| eventId=6 msg=Additional Data Test start=1687328307386 end=1687328307386 ad.deviceowner=Device Owner ad.devicehostname=Device Host Name

Logger search results:
First event (without ngmappings.adatamappings.properties) and second event (with ngmappings.adatamappings.properties)

You can see additional data ad.deviceowner and ad.devicehostname of the first event are mapped to flexString1 and flexString2 ArcSight fields of second event respectively.

Raw messages in Logger:
First event (without ngmappings.adatamappings.properties):
