using multiple targets with prometheus

[Rayn doll]

We need to monitor several of target with prometheus, when we have a short list of targets 

it was not a problem to modify, however we need to add many targets (50-70 new targets) from diffrent clusters

My question if there is a more elegant way to achieve this 

instead of using it like this

    - job_name: blackbox-http # To get metrics about the exporter’s targets

      metrics_path: /probe

      params:

        module: [http_2xx]

      static_configs:

        - targets:

          - http://clusterA   

          - https://clusterA   

          - http://clusterB 

          - http://clusterC 

          - http://clusterC 

            ...

maybe to mount additional files for each cluster , I mean to provide a file with targets for clusterA only and new file for clusterB only etc, is it possible ?

Yes, use file_sd_configs instead of static_configs.

    file_sd_configs:

      - files:

        - /etc/prometheus/targets.d/cluster_a.yml

        - /etc/prometheus/targets.d/cluster_b.yml

This has the additional advantage that prometheus automatically detects whenever these files change - you don't need to send it a signal to re-read them.

Thanks a lot! could you please provide some file same, how it looks like?

There is an example (in JSON format) in the section I linked to:

https://prometheus.io/docs/prometheus/latest/configuration/configuration/#file_sd_config

But YAML is also permitted.  In your case it might look like this:
