PromPress tracks various website and WordPress related metrics for collection by <a href="https://prometheus.io/" rel="nofollow ugc">Prometheus</a>, which allows you to monitor your site’s performance and health. You can even setup dashboards with <a href="https://grafana.com/" rel="nofollow ugc">Grafana</a> and/or setup alerting via <a href="https://prometheus.io/docs/alerting/latest/alertmanager/" rel="nofollow ugc">Prometheus Alertmanager</a>.
(Note: Requires Object Caching via Redis to be active, so that the plugin can store metrics.)
We track a range of Website and WordPress specific metrics:
<ul>
<li>Request Count</li>
<li>Request Duration</li>
<li>Request Peak Memory Usage</li>
<li>External Request Duration</li>
<li>Query Count</li>
<li>Query Duration</li>
<li>Plugin Updates</li>
<li>Theme Updates</li>
<li>Emails Sent</li>
<li>User Count</li>
<li>Post Count</li>
<li>Option Count</li>
</ul>
This gives you the ability to monitor the performance of your website over time and get an early warning of potential problems, like your site sending a lot of emails or the post count increasing a lot.
We purposefully avoid general software and/or server level metrics which are better handled outside of the website, like detailed database metrics which is better handled via the <a href="https://github.com/prometheus/mysqld_exporter" rel="nofollow ugc">mysqld exporter</a>.
