Add a independent trendline in splunk

karthi25 — Mon, 08 Jan 2018 10:57:22 GMT

I am having the chart with durations, I want to add a line over the chart with values as avg(duration). I used below query, it works perfectly.

index=cloudfoundry sourcetype=cl**** "cf_foundation=px**" "cf_org_name=Co***" "cf_space_name=de***" "cf_app_name=splunk-log****" "||splunk-logger||" | dedup processLogId| sort -splunkId |search endDate !=null AND status='COMPLETED' |eval start_epoch=strptime(startDate,"%Y-%m-%d %H:%M:%S.%1N")
 |eval _time=start_epoch
 |eval end_epoch=strptime(endDate,"%Y-%m-%d %H:%M:%S.%1N")
 |eval duration=round((end_epoch-start_epoch)/60)
  | chart values(duration) as duration by processLogId | eventstats avg(duration) as avg_duration

But now my requirement was changed that, Chart should based on last 30 days(may vary) and trendline should only based on last 7 days.

Kindly help me to do it

hey @karthi

I got the answer for this question try the same search:

index=cloudfoundry sourcetype=cl**** "cf_foundation=px**" "cf_org_name=Co***" "cf_space_name=de***" "cf_app_name=splunk-log****" "||splunk-logger||" | dedup processLogId| sort -splunkId |search endDate !=null AND status='COMPLETED' |eval start_epoch=strptime(startDate,"%Y-%m-%d %H:%M:%S.%1N")
  |eval _time=start_epoch
  |eval end_epoch=strptime(endDate,"%Y-%m-%d %H:%M:%S.%1N")
  |eval duration=round((end_epoch-start_epoch)/60)
   | chart values(duration) as duration by processLogId | eventstats avg(duration) as avg_duration

And then go to format>>chart overlay>>overlay>>select avg_duration
OR in XML just put <option name="charting.chart.overlayFields">avg_duration</option>

let me know if this helps!

@mayurr98 Where can I give the time range for the trendline, because the time range for the chart and trendline is different right?
