==================
You can configure metrics support by adding the following to your config:
\`\`\`yaml
metrics:
enabled: true
bindAddress: 127.0.0.1
port: 9002
\`\`\`
An example dashboard that can be used with [Grafana](https://grafana.com) can be found at [/contrib/hookshot-dashboard.json](https://github.com/matrix-org/matrix-hookshot/blob/main/contrib/hookshot-dashboard.json).
There are 3 variables at the top of the dashboard:

Select the Prometheus with your Hookshot metrics as Data Source. Set Interval to your scraping interval. Set 2x Interval to twice the Interval value ([why?](https://github.com/matrix-org/matrix-hookshot/pull/407#issuecomment-1186251618)).
Below is the generated list of Prometheus metrics for Hookshot.

Object.entries(categories).forEach(([name, entries]) => {
console.log(`## ${name}`);
console.log('| Metric | Help | Labels |');
console.log('|--------|------|--------|');
entries.forEach((e) => console.log(`| ${e.name} | ${e.help} | ${e.labels.join(', ')} |`));
});
