Note
The default port of the exporter is 9101.

Usage

Usually promethues exporters are run as a systemd service. This way you can define it once and forget about it even running. Here is a working example of configuring Bench Exporter with Systemd.

# bench_exporter.service

[Unit]
Description=Bench Exporter
Wants=network-online.target
After=network-online.target

[Service]
User=root
Group=root
Type=simple
ExecStart=/usr/local/bin/bench_exporter --bench /home/frappe/frappe-bench --users

[Install]
WantedBy=multi-user.target

Here you have to replace the bench-exporter path and the path to your bench.

You can enable and start the service with,

$ systemctl enable bench_exporter.service
$ systemctl start bench_exporter.service

Once you've started the bench_exporter service, You can navigate to https://localhost:9101/metrics and you can see the metrics.

Grafana

Once Prometheus fetches the data, you can connect Prometheus to Grafana server which could use the promethues data to display the fetched data into a more insightful manner.

You can create a new dashboard in Grafana to fetch the data. You can find a demo dashboard which uses Bench Exporter's data in the dashboards folder. You can read more about importing dashboards here.
