Disk space alert

[sundarv1]

How do I setup alerts for the below conditions for hosts.

1. Disk space between 85 to 90

2.Disk space greater than 90

Hi 
In the Settings Anomaly detection Disks

you can find the bellow configuration (for all hosts, disks)_.

You can do the same in the host level.

otherwise, you can build your proper metric event based on the bellow metrics

How to at metric level for a range 

85 to 90 - Warning

Greater 90 - Error

[Malaik]

No range available for the configuration

You should decide to make it different, for example:

Process group availability monitoring 

85 - Warning

90 - Major

Greater 90 - Error (or critical)

[sundarv1]

Please let me know how to do this across all hosts with example

[PacoPorro]

Try with this metric selector:

builtin:host.disk.usedPct:filter
(and
      (or(in
      ("dt.entity.disk",entitySelector("type(disk)")))
      ),series(avg,and(ge(85),le(90))))
:splitBy("dt.entity.disk"):parents

Hi @sundarv1 
Complementing what PacoPorro mentioned, I think an alternative is this:
Alerting based on % of Disk used by Host.

1. Disk space between 85 to 90

  Metric Selector

builtin:host.disk.usedPct:filter(and(or(in("dt.entity.host",entitySelector("type(host),entityName.equals(~"HOST_NAME~")")))),series(avg,and(ge(85),le(90)))):splitBy("dt.entity.host"):parents

Config in Metric Event (Monitoring strategy) 

Since the metric only brings values in that interval, the metric will warn exactly when there are values greater than 85.

2.Disk space greater than 90

builtin:host.disk.usedPct:filter(and(or(in("dt.entity.host",entitySelector("type(host),entityName.equals(~"HOST_NAME~")"))))):limit(20)

Config in Metric Event (Monitoring strategy) 

I hope it's helpful 💪
