DMC alert for Disk usage

Contributor

HI All,

We are receiving false alert in the DMC and checked the search it running following rest search . In that free and available diskspace having 100+ GB differents. How to fix it ?

| rest splunkservergroup=dmcgroup* /services/server/status/partitions-space

Output :
server  capacity  free  available 
idx10   2TB   188GB   83GB 

Thanks

Hi rsathish47!

The DMC alerts are configurable and can be set by navigating to the Platform Alerts Setup page.

alt text

You can then select the DMC Alert - Near Critical Disk Usage and configure the desired threshold.

The default threshold is 80%, which based on the output of that rest call, you have definitely breached.

Is the output you shared accurate when comparing to check from the indexer's cli?

Thank You mmodestino, we have configured for 97% in disk usage.

Different between free and available is too much. is there anywhere we can fix this?

Ah! I see what you mean.

What version of Splunk are you running?

Also, try removing the wildcard from this search and hitting the endpoint for that indexer only.

| rest splunk_server=Idx10 /services/server/status/partitions-space

Is this the only Idx with this situation?
