Assigning tag to disks

[JAR1]

Hello all,
is there any way to tag the disks of a hosts (linux). My client needs to send a tag=<value> to an alert integration (serviceNow).
The situation is:
if disk is /opt then tag1=value1
if disk is /opt/wl then tag1=value2

any idea? has anyone encountered a similar situation?

Thanks

You could try assigning a TAG using automatic tags and an Entity selector type rule.

Download the list of entities via the API and see what drives you have available:
https://www.dynatrace.com/support/help/dynatrace-api/environment-api/entity-v2/get-all-entity-types

I'm not sure if you can assign a tag to a specific partition on a given host, but you have to try in the direction I described above.

Hi @JAR1,

On the GUI it is not possible to create auto tag for disks:

I quikly tried the API possibilities.

As Radek suggested I used the first API entity selector for a specific disk (/tmp mount from a hsot). I could see that there was a tag [] section.

https://www.dynatrace.com/support/help/dynatrace-api/environment-api/entity-v2/entity-selector

Then I used the Cutom tags API  https://www.dynatrace.com/support/help/dynatrace-api/environment-api/custom-tags/post-tags

With this settings. All /tmp mounts (79 were found) were tagged with tag1=value1

Then I checked the specific disk as I did at the fisrt step. Here is the result.

If you want test it in the problem integration.

I hope it helps.

Best regards,

Mizső

@JAR1,

As @Mizső said, through the API, it is quite easy. I have done this in a client, for differentiated disk alerting. Ans as @radek_jasinski has said, thorugh an entity selector, you should also be able to do it (have not tried myself).
