How to identify Splunk Instance role by internal logs?

Hi there,

prologue:
in my clustered environment i have a search head which is dedicated to a special user group and should serve a very simple dashboard view for system status overview (just some icons like "Indexers OK" " Search Heads Not OK" 🙂 ). It is connected to the indexer cluster which has all the internal data from every connected Splunk environment. The MC (Monitoring Console) is not configured on it.

question:
i assume all the necessary data is in the _* indexes like _internal. How do i identify the "system role" within this data?

I can identify forwarders with "index=_internal source=*metrics.log group=tcpin_connections..." but how about other "roles"?

Any ideas are very welcome.

thanks,
swe

Clicking on the link doesn't work for me, either, but copy-and-paste into a new browser tab worked. Odd.

Easiest way is to setup DMC in any of the system. If not, setup in your local laptop and you can get all the queries for DMC

enjoy
| rest/services/server/info | table host server_roles
btw, what do you want to be reported on when you say Indexer "OK" ?

take the hosts from the search above and create a search:
index= _internal host =1 or host=2 ... or host=n | timechart span=5m count by host
this will tell you how many events are indexed every 5 minutes by your splunk instances.
save as an alert if count = 0
