Metric event throttled for disk warning in metric selector

Vijayt — Thu, 18 Dec 2025 10:34:54 GMT

i have written metric event for disk warning with metric selector but i am getting metric event throttled ..

1. metric event filters with

a. host with group / team supporting it

b. exclude disk with EXCLUDE tag

how to mitigate this

i tried with metric key but there is no option to filter both entity tag and disk tag

Hi,

If you are in Grail, best way would be using Davis Anomaly Detector instead.

If you are not in Grail, you need to split it in chunks. But I would recommend using Disk Edge instead of a custom metric event.

Best regards

ours is infra only mode. no grail access. it is not only for disk other metric events as well throws throttled

//you need to split it in chunks.// you mean further add dimention in split by ?

for example

remote_unix.mount_capacity:filter(and(or(eq(network zone, NW-112)),
or(not(in("dt.entity.remote_unix:host",entitySelector("type(remote_unix:host),tag(~"OS_type:hpux~")")))),
or(in("dt.entity.remote_unix:host_group",entitySelector("type(remote_unix:host_group),entityName.contains(~"remote~")"))))):splitBy("dt.entity.remote_unix:host",mount)

Hi,

I would suggest using Disk Edge instead. But if you want to use metric events, you need to split by some dimension / tag / hostname...

Best regards
