Testing Nmon performance with evengen¶
Splunk Evengen is a pretty good and straightforward way to test the application.
Starting the TA-nmon version 1.3.28 and TA-nmon-hec version 1.3.32, we provide sample data for 2 AIX and 2 Linux servers. The data has been generated on IBM Power Development Cloud servers.
Finally, we use to run a system stress tool on 1 server of each category, such that you will have quickly active alerts and system statistic anomalies.
Eventgen will generate data for:
- performance metrics (sourcetype=nmon_data / eventtype=nmon:performance)
- configuration data (sourcetype=nmon_config / eventtype-nmon:config)
Additional data normally available within the application is related to the nmon data collection and will not be generated by Eventgen.
Get it working in 30 seconds¶
- Have a Splunk instance up and running
- Download the current eventgen version from https://github.com/splunk/eventgen
- Install the eventgen application, you should name the application directory as:
- If not done already, install the Nmon Performance application (obvious!)
- Install either the TA-nmon or the TA-nmon-hec on this instance
- Create an index called “nmon”
- Restart Splunk
Immediately after Splunk restart, eventgen starts to generate nmon data, as visible from the application home page:
