How to create an alert to trigger when the license usage of a heavy forwarder reaches 90%?

Engager

Hi...I wanted to know how we can create an alert when the license usage of a "heavy forwarder" reaches a threshold say about 90% of license usage. We want to get alerted when such a thing occurs. Currently I have the following search:

index =_internal source = *license_usage.log* type = Usage earliest=-7d@d latest=now | search h=ftlpsplunkfwd01.citrite.net | eval MB=b/(1024*1024)  | eval date=strftime(_time, "%1m/%0d/%Y") | stats sum(MB) as Usage(MB) by date

Maybe something like this:

index=_internal source=*license_usage.log type=Usage earliest=-7d@d latest=now
| search h=ftlpsplunkfwd01.citrite.net
| eval MB=b/(1024*1024) 
| eval date=strftime(_time, "%1m/%0d/%Y") 
| stats sum(MB) as Usage(MB) by date
| appendcols [ 
   | rest splunk_server=local /services/licenser/stacks 
   | stats max(quota) as license_limit
   | eval license_limitMB = license_limit/1024/1024
   | fields license_limitMB
]
| eventstats max(license_limitMB) as license_limitMB
| eval license_usage = round('Usage(MB)'/license_limitMB*100, 2) 
| where license_usage > 90

Keep in mind the last line is filtering where license usage > 90% so try tweaking that.
If that doesn't give you any result, try removing the second line (search h=...) and the earliest and latest filters.

Not getting a result could be good thing. The denotes that your HF is not exceeding the 90% of total license usage. TO double check the values, just remove the last line and validate the results.
