Update dashboard about elasticsearch_exporter HOT 5 CLOSED

Ah nice, thanks for the tip. If you want to include a section in the README for AWS users, and for anyone else who may look for this in the future, this is what worked for us:

  - job_name: ec2
    ec2_sd_configs:
      - region: eu-west-1
        access_key: xxx
        secret_key: xxx
        profile: xxx
        port: 9100
    relabel_configs:
      - source_labels: [__meta_ec2_tag_Name]
        target_label: instance
      - source_labels: [instance]
        regex: (.*elasticsearch.*)
        target_label: cluster
        replacement: elasticsearch

Our instances contain the word elasticsearch, so the regex may need to change if yours aren't set up the same way.

Hi,
sorry for the late reply. The dashboard relies on a relabeling config that adds a label "cluster" to the elasticsearch_exporter metrics (described in https://github.com/justwatchcom/elasticsearch_exporter#alerts--recording-rules).
If you add such a label, the dashboard should work.

Hi @zwopir - would you be able to elaborate on how this works? For example, I'm using the aws ec2 module for discovery, and the elasticsearch exporter is running on a central prometheus server, so the name of the prometheus server is useless. I've got a relabel_configs block setup in the ec2 job which takes the __meta_ec2_tag_Name and puts it into an "instance" label, which is also in turn labelled as cluster. So it is available in the ec2 job, but it's not showing up in the dashboard.

Any ideas?

it's not the elasticsearch_exporter that needs the label cluster added, but the node_exporter(s) that a running on the ES nodes. The elasticsearch_exporter itself gets the cluster label from the ES API.

So if the __meta_ec_tag_Name matches the cluster label value you get from the elasticsearch_exporter, the dashboard should work. Otherwise you need so set the value, either manually in the job definition via labels (https://prometheus.io/docs/prometheus/latest/configuration/configuration/#static_config) or via rewriting from some aws ec labels.

Hi @mtanatwine ,

thanks for getting back on this issue, great it worked for you. Your use case is a bit too specific (how your labels are named) to include in the README, but a link to this issue might help people. I'll add it to the README
