How to configure custom Prometheus exporters on DreamHost?
To configure custom Prometheus exporters on DreamHost, follow these steps:
- Access your DreamHost server via SSH or any other preferred method.
- Create a directory where you want to store your custom exporters. For example, you can use the /opt/prometheus/exporters directory. mkdir -p /opt/prometheus/exporters/
- Copy your custom exporter binary/executable to the created directory. Ensure that the exporter is compatible with your operating system and architecture.
- Create a systemd service unit file to manage the exporter process. Use any text editor (e.g., nano, vi) to create a new file at /etc/systemd/system/exporter.service for the exporter service. sudo nano /etc/systemd/system/exporter.service
- In the service unit file, paste the following configuration: [Unit] Description=Custom Prometheus Exporter After=network.target [Service] User=prometheus ExecStart=/opt/prometheus/exporters/[Install] WantedBy=multi-user.target Replace with the actual name of your custom exporter binary.
- Save and close the file.
- Reload the systemd daemon for the changes to take effect: sudo systemctl daemon-reload
- Enable the exporter service to start automatically on boot: sudo systemctl enable exporter.service
- Start the exporter service: sudo systemctl start exporter.service
- Verify that the exporter is running without any errors: sudo systemctl status exporter.service
- Once the exporter is running, you can configure Prometheus to scrape metrics from it. Update your Prometheus configuration file (prometheus.yml), usually located at /etc/prometheus/prometheus.yml, to include the target URL of your custom exporter.
Here's an example configuration for a custom exporter target:
1 2 3 4
scrape_configs: - job_name: 'custom_exporter' static_configs: - targets: ['localhost:XXXX']
localhost:XXXX with the appropriate IP and port of your custom exporter.
- After updating the Prometheus configuration, reload or restart the Prometheus service to apply the changes: sudo systemctl reload prometheus.service
That's it! Your custom Prometheus exporter should now be configured and accessible for scraping by Prometheus.
What is the Prometheus data retention policy on DreamHost?
As of my last update, DreamHost does not have a predefined data retention policy specifically for Prometheus. However, they provide the option for users to retain and manage their own data. Therefore, the data retention policy for Prometheus on DreamHost would depend on the settings and configurations set by individual users. It is recommended to refer to DreamHost's documentation or contact their customer support for the most accurate and up-to-date information on data retention policies for Prometheus.
