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
server capacity free available
idx10 2TB 188GB 83GB
The DMC alerts are configurable and can be set by navigating to the Platform Alerts Setup page.
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?
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?
