Change of metric name for legacy logs

[pmurray30]

Did anyone else notice over the weekend (10/11th Feb) the metric for the security group a VM is in changed from dt.security_context to dt.host_group.id?

Came in on Monday and my dashboards stopped as had to change:

(dt.security_context="***-prod" OR dt.security_context="***-prod-dr") and loglevel="error"

to

(dt.host_group.id="***-prod" OR dt.host_group.id="***-prod-dr") and loglevel="error" 

Just wondering what changed.

Regards

Paul

Cluster updates can have this affect, I recommend always checking out what's coming up, they can be viewed here: https://docs.dynatrace.com/docs/whats-new/release-notes 

Do you recall the Cluster Version you were on when the change showed up? Are you SaaS or Managed? Given your reported time of the change, I'm going to assume Managed. The associated release for managed at that time frame is here where it reports the break potential: https://docs.dynatrace.com/docs/shortlink/release-notes-oneagent-sprint-283#removed-default-values-o...
