Prometheus exporter for Sun ALOM statistics

Project description


This connects to an instance of Sun Advanced Lights-Out Management (ALOM) via SSH and exports metrics about the host system to Prometheus! It has been tested on Sun T1000 and T2000 systems so far- please try it with your system and file a bug if it's not compatible. It is currently focused on showenvironment metrics: voltage/amperage/temperature, for safety and environmental monitoring. The system running this exporter requires the following:

  • python3
  • Network access to the management interface of your target server
  • Credentials for logging into the target server in a configuration file, like the following:
alom_ssh_address: ''
alom_ssh_username: admin
alom_ssh_password: changeme

This file is YAML-formatted and is passed to the alom_exporter script with the -c/--config option.

Since the showenvironment command doesn't require administrative privileges, I'd recommend setting up a dedicated user for alom_exporter to adhere to the principle of least privilege.

For example, here's how to add an unprivileged user to an ALOM console.

sc> useradd exporter
sc> userpassword exporter
New password: *********

Re-enter new password: *********

sc> usershow exporter
Username         Permissions      Password
exporter         ----             Assigned

Make sure the username and password entered at the console match what you entered in the config.yaml file.


Install via pip, pip install alom-exporter - and note the package name uses a dash. The daemon can be invoked with alom_exporter.


This was generated from example output of a Sun T2000 server. Python metrics are omitted for brevity.
