Gathering Six Months of Trend Data

Explorer

I'm still relatively new to Splunk and am having trouble understanding Timechart and the proper syntax for it. I'm looking to gather 6 months worth of Trend data for compliance purposes. Currently, I've got the following in order to get the initial (monthly) data point so that each month it updates to the new 6 month window:

search query | dedup 2 items | stats count(eval(state="passed")) AS Passed, count(eval(state="failed")) AS Failed | eval Percent_Compliance=(100-((Failed/Passed)*100))

I assume that I want to set the search range as 6 months instead of 1 month, but outside of that I don't really understand how to implement timechart or if there is a better solution. Thank you in advance.

If you want to see a trend of last 6 months over 1 month span,

try

search query earliest=-6m@m| dedup 2 items | timechart span=1mon count(eval(state="passed")) AS Passed, count(eval(state="failed")) AS Failed | eval Percent_Compliance=(100-((Failed/Passed)*100))

It's returning 0 results at this moment. Perhaps I missed something? For simplicity sake here's the whole thing:

index=bigfix sourcetype="bigfix:compliance" sourceseverity="high" state="passed" OR state="failed" earliest=-6m@m | dedup compid checkid | timechart span=1mon count(eval(state="passed")) AS Passed, count(eval(state="failed")) AS Failed | eval PercentCompliance=(100-((Failed/Passed)*100))

That's generating 0 results, where as before the timechart addition it would show the checks that passed, failed, and the percentage of it.

Thanks for your help!
