hel p for calculating an interval in seconds between now date and a timestamp event

[jip31]

hello

I need to monitore events included in a now() date and the event creation date
So I need to calculate the interval between these 2 dates in seconds
I have no error when I execute my code but the DiffInSeconds eval doesnt works correctly
So I think there is something wrong
For example, if the now() date time is 9:00 and the event creation date time is 9:05 (so 300 seconds), normally I should have some events displayed because if I execute just index="x" sourcetype="winhostmon" Type=Service Name=SplunkForwarder I have events
so what is the issue p^ease??

index="x" sourcetype="winhostmon" Type=Service Name=SplunkForwarder 
 | eval timenow =now() 
 | eval EventCreatedTime=_time 
 | eval DiffInSeconds = (timenow - EventCreatedTime) 
 | eval Status=if(DiffInSeconds<900, "Online", "Offline") 
 | convert timeformat="%d-%b-%Y %H:%M:%S %p %Z" ctime(EventCreatedTime) 
 | table host EventCreatedTime DiffInMinutes Status

Hi @jip31,

Great job on making the query the only problem is that you need only one entry per host and in your case you will end up with many. I've done some optimization by replacing some of your commands, it should work like this :

index="_internal" sourcetype="splunkd"
| stats latest(_time) as _time by host
| eval DiffInSeconds = (now() - _time) 
| eval DiffInMinutes=DiffInSeconds/60
| eval Status=if(DiffInSeconds<900, "Online", "Offline") 
| eval EventCreatedTime=strftime(_time,"%d-%b-%Y %H:%M:%S %p %Z" )
| table host EventCreatedTime DiffInMinutes Status

Let me know how it works out for you.

Best regards,
David

I couldn't find any major issues in your search, except the DiffInMinutes field
Please try

index="_internal" sourcetype="splunkd"
  | eval timenow=now() 
  | eval EventCreatedTime=_time 
  | eval DiffInSeconds = (timenow - EventCreatedTime) 
  | eval Status=if(DiffInSeconds<900, "Online", "Offline") 
  | convert timeformat="%d-%b-%Y %H:%M:%S %p %Z" ctime(EventCreatedTime) 
  | eval DiffInMinutes=DiffInSeconds/60
  | table host EventCreatedTime DiffInMinutes Status

cheers
