Split string in alertmanager.

[Jhanssen Fávaro]

Hi folks,

I am used to split a few strings in my ansible playbooks, so I thought it would be helpfull in prometheus as well...

Anybody knows how to execute that ?

Sample:

    - alert: Under_Replicated_Partition_Count

      expr: sum(kafka_server_replicamanager_underreplicatedpartitions) by(env,instance) > 0

      for: 1m

      labels:

        severity: critical

        oid: "1.3.6.1.4.1.50495.15.1.2.3.1"

        instance: "{{ $labels.instance|split(':')[0] }}"

      annotations:

        summary: 'Kafka {{ $labels.service_name }}: {{ $value }} under replicated partitons'

        description: 'Under-replicated partitions means that one or more replicas are not available. This is usually because a broker is down.  Restart the broker, and check for errors in the logs.'

Best regards

Jhanssen

You can use reReplaceAll for that.
