Change default port for prometheus

[imoh...@gmail.com]

Hi,

I just downloaded prometheus version 1.7.1 and I want to run it but I have  small problem, there is another process which listens on port 9090 so I need to change the port where prometheus listens on to make it port 9091 for example but this seems does not work at all, here is my config file after stripping comments:

global:

  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.

  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.

  external_labels:

      monitor: 'codelab-monitor'

rule_files:

scrape_configs:

  - job_name: 'prometheus'

    static_configs:

      - targets: ['localhost:9091']

This is the error message:

ERRO[0000] Error starting web server, exiting gracefully: listen tcp :9090: bind: address already in use  source="main.go:238"

I hope someone can help me, thanks a lot.

The config is for what to collect, to change the running listening port, you have to set a command line flag.

Set  -web.listen-address ':9091'

I just found this option --web.listen-address="0.0.0.0:9091".

Can I make this change permanent using the configuration file?

No, the configuration file is for options that can change dynamically.  Changing the listen address is not possible on the fly.
