Data Description
The LOGS event is used in SAP to view any text file from the SAP application server.
Potential Use Cases
This event could be used for the following scenarios:
Correlate batch job failures to the work process trace files.
Identify environment-wide concerns if a work process cancels.
Alert on specific error messages in the environment within the server logs.
Metric Filters
The metric filter for the LOGS extractor can be found by logging into the managed system and executing the /n/bnwvs/main transaction. Then go to Administrator → Metric Filters → Logs file filter.
...
To enter a new filter value, select the add row option, and enter the values based on the options above. Save, and the data will be extracted.

Splunk Event
The event will look like this in Splunk:
...
SAP Navigation
Navigate to this data by logging into the application server, and accessing the directory which has been specified in the data extraction format. Alternatively the data can be accessed by using the AL11 t-code. To access the information using the AL11 t-code, execute the transaction in the managed system. For this example we will access a file in the following directory path: (E:\usr\sap\ID8\DVEBMGS00\work). Once you are in the transaction double click on the directory path that was specified in the Metric Filters configuration.
...
The information displayed below will match the information that is passed to Splunk. Once the log file is specified in Metric Filters, the extractor is able to extract the timestamp from each line, so logs are pushed with timestamp metadata. For the rest test files, it will be text with a timestamp when the data was extracted (not the actual time, when entry is added in the log).
