Advanced detection rule for process group

AK — Fri, 07 Apr 2023 10:45:43 GMT

Hi Team,

With the advanced process group detection rule, I'm able to get the process groups below
process-1-1234-ab1c, process-2-5678-xy1z, and so on...

I would like them to be detected as,
process-1,process-2

There is no option to apply regular expression, only delimits from and to option are present

Can someone help to achieve this?
Regards,
AK

Since it's the name you want to change, could you not use a Process Group Naming Rule - https://www.dynatrace.com/support/help/platform-modules/infrastructure-monitoring/process-groups/configuration/pg-naming

That allows regex

@Tom_Eaton , Thanks for the response,
I think, I missed to add that, the process groups 'process-1-1234-ab1c, process-2-5678-xy1z' are detected via 'advanced process group detection rule' and because this rule, it keeps creating process groups like below,

process-1-1234-ab1c, process-1-3211-fd5j, process-1-3298-vbs5, and so on..

process-2-5678-xy1z, process-2-9845-ab1c, process-2-0121-ret3, and so on..

process-3-8765-xsf1, process-3-6544-q2we, process-3-5890-1aws, and so on..

and so on...

If I use 'process naming rule' to exclude content after second hyphen (-) for above process groups then, there will be lot of process groups with same name. If we take example for above case then, after applying process group naming rule it will be like below,

process-1, process-1, process-1, and so on.. (Process group)

process-2, process-2, process-2, and so on.. (Process group)

process-3, process-3, process-3, and so on.. (Process group)

and so on...

So process group naming rules will not help. We need to build a 'process detection rule' that will group a processes like below,

process-1 (Process group)

--> process-1-1234-ab1c, process-1-3211-fd5j, process-1-3298-vbs5, and so on.. (Process group instance)

process-2 (Process group)

--> process-2-5678-xy1z, process-2-9845-ab1c, process-2-0121-ret3, and so on.. (Process group instance)
process-3 (Process group)

--> process-3-8765-xsf1, process-3-6544-q2we, process-3-5890-1aws, and so on.. (Process group instance)

Regards,

Are there any other unique identiefiers within the process? If not perhaps it's possible to work with an environment variable within the process?

https://www.dynatrace.com/support/help/platform-modules/infrastructure-monitoring/process-groups/configuration/pg-detection

Check the part about environment variables?

You can try to use environment variable DT_CLUSTER_ID=process-1 to skip all built-in \ additional user defined rules.

We use this approach in k8s - to have no set of rules in the interface and to be able to manage the name of the process group from the yaml manifest by application\infra team.

Or try to use "advanced process group detection rule" with environment variables as @michiel_otten replied.

@Romanenkov_Al3x, thank you for the response.

Where I can find the variables that are passed, does it show anywhere on Dynatrace console or I have to look into kubernetes.yml?

I'm observing some 'Kubernetes annotations' at process group instance level, can we make use of that in detection rule?

Regards,

Thank you for help and suggestions everyone.
Well, my colleague help me to do it successfully. Here is how we achieved it.

Created a advanced detection rule to extract process groups with numbers and then created a process group naming rule to give desired names to process groups,

Using 'Advanced detection rule process groups transformed to,

1 (Process group) --> 1, 1, 1, and so on.. (Process group instance) 2 (Process group) --> 2, 2, 2, and so on.. (Process group instance) 3 (Process group) --> 3, 3, 3, and so on.. (Process group instance) . . and so on...

Applied process group naming rule to make it like below,

process-1 (Process group) --> process-1, process-1, process-1, and so on.. (Process group instance) process-2 (Process group) --> process-2, process-2, process-2, and so on.. (Process group instance) process-3 (Process group) --> process-3, process-3, process-3, and so on.. (Process group instance) . . and so on...
