Count is used to specify how many events should leak out per interval. It’s important to remember, the default interval is set to 60s, even if you do not specify an interval, there will be one added to your stanza. This will use sample mode, which take a file and either dump the entire file, or randomly select subset of that file every X seconds, defined by the count and interval. Next, lets build a basic noise generator from a log file. Assuming that meets all your needs, you might want to skip to the Deployment section. Wrapping up the first exampleįind a real world example of what you want to generate events off, extract it from Splunk or a log file, and toss it into Eventgen. Eventgen will sleep between events as it sees gaps in the events in the source log. You should now see events showing up on your terminal window. Python -m splunk_eventgen generate README/1 Run the command below from directory $EVENTGEN_HOME/splunk_eventgen. For testing purposes, change outputMode = stdout or outputMode = modinput to visually examine the data. You can easily run these examples by hand. Please note, replaytimestamp means replace a replay with the time difference of the original event difference, where timestamp will always replace the time with “now”. Eventgen needs to be told which field / regex to use for finding out the difference in time between events. should always be used to find and replace the replaytimestamp. Third, make sure you find all the different time formats inside the log file and set up tokens to replace for them, so limiting your initial search to a few sourcetypes is probably advisable.When using splunk search to build your replay, please append | reverse | fields index, host, source, sourcetype, _raw to your Splunk search and then doing an export to CSV format. Second, csv only uses index, host, source, sourcetype and _raw fields.First, Eventgen assumes its sample files are in chronological order.Replay also can take a regular log file (in which case, you can omit sampletype=csv). To build a seed for your new Eventgen, start by taking an export from an existing Splunk instance. By default replay mode it will rest the default interval (60s) and then automatically start over from the beginning. When Eventgen reaches the end of the file, it can be configured to start over, stop or rest an interval and begin all over. Eventgen will pause the amount of time between each event just like what happened in the original, so the events will appear to be coming out in real time. Eventgen can take an export from another Splunk instance, or just a plain text file, and replay those events while replacing the time stamps. Replay mode is likely to cover 90% of the use cases you can imagine. In the event you hit an issue, please post to the Issues page of the eventgen github repository (/splunk/eventgen). For a complete reference of all available configuration options, please check out the. This should hopefully get you through setting up a working eventgen instance.
