Static field value

bsaujla131984 — Wed, 30 Sep 2020 03:55:04 GMT

I have created a dashboard to show windows server uptime.

Now I would like to add application name of all servers. For example, Application A is hosted on Server A and Application B is hosted on Server B. I want to show these application in the dashboard corresponding their respective server names.

index = Index host=ServerA OR host=ServerB OR host=ServerC OR host=ServerD OR host=ServerE | eval Uptime_Days = System_Up_Time/86400 | chart max(Uptime_Days) as "System Uptime in Days" by host | sort -Uptime_Days

A lookup table should do the job. Create a CSV file with an "Application" column and a "Server" column. Then reference the lookup in your query.

index = Index host=ServerA OR host=ServerB OR host=ServerC OR host=ServerD OR host=ServerE 
| eval Uptime_Days = System_Up_Time/86400 
| chart max(Uptime_Days) as "System Uptime in Days" by host 
| sort -Uptime_Days 
| lookup servers.csv Server as host OUTPUT Application 
| table host Application Uptime_Days

I think this is best achieved with a lookup.

This thread should get you pointed in the right direction:

Hope that helps!

I tried as suggested, but not getting any server up time now.

Thanks Rich, it worked by just tweaking a bit as below :-

index = Index host=ServerA OR host=ServerB OR host=ServerC OR host=ServerD OR host=ServerE
| lookup servers.csv Server as host OUTPUT Application
| eval Uptime_Days = System_Up_Time/86400
| stats max(Uptime_Days) as "System Uptime in Days" by host Application
