How to configure prometheus.yml file to have multiple host

[sig...@gmail.com]

Hi Team,

Greetings,

I may be asking the dumbest question here. I am trying to configure Prometheus to monitor docker swarm and the services running within the swarm. Can someone please help me with the configuration file. I am facing difficulty in adding the host to the prometheus.yml file. If I run the docker file with localhost its running fine. But if i add the swarm host ip then the docker itself is not starting.

Looking foeward for your help .

Regards,
SD

I am trying with the below configuration

root@prometheus:/prometheus-data# vim prometheus.yml
global:
  scrape_interval: 5s # By default, scrape targets every 15 seconds.
  evaluation_interval: 5s
  # Attach these labels to any time series or alerts when communicating with
  # external systems (federation, remote storage, Alertmanager).
  external_labels:
    monitor: 'Prometheus_Monitoring'

rule_files:

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'prometheus'

    # Override the global default and scrape targets from this job every 5 seconds.
    scrape_interval: 5s

    static_configs:
      - targets:
           ['localhost:9090']

- job_name: 'docker-swarm-manager'

    # Override the global default and scrape targets from this job every 5 seconds.
    scrape_interval: 5s

    static_configs:
      - targets:
           ['10.140.0.3:8080']

What is port 8080 in this scenario?

For docker swarm, you will need a bridge to handle service discovery.

Take a look at this option:

No, there is not currently native docker swarm support.  It is possible to use docker swarm's DNS server to do DNS-based discovery.

See the issue linked from the adapter readme:
