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: '192.168.1.231'
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.
Daemon configuration files are provided for systemd-based Linux distributions and OpenBSD- check service/alom_exporter.service and service/alom_exporter.rc.sh respectively. Both run with a daemon user that must be created before using the files. These two files assume the installation is at /usr/local/bin/alom_exporter with configuration at /etc/alom_exporter.yaml -- adjust this to fit your environment.
This was generated from example output of a Sun T2000 server. Python metrics are omitted for brevity.
