Advanced Monitoring helps you keep your Plesk running smoothly by tracking the server resources usage
and notifying you when one or more resources usage reaches a pre-defined threshold.
Advanced Monitoring works in tandem with the Grafana extension
and uses Grafana to display server metrics as graphs and dashboards.
The Advanced Monitoring and Grafana extensions are installed in Plesk Obsidian by default.
Note: If you upgraded to Plesk Obsidian from Plesk Onyx
and had Server Health Monitor installed,
Advanced Monitoring will be automatically installed and will replace Server Health Monitor.
Tracking Advanced Monitoring Graphs
Advanced Monitoring is located in the main left panel.
The resources and services monitored by Advanced Monitoring are separated into five categories,
each one is shown on its own tab.
The values displayed in Advanced Monitoring
reflect the resource usage at the moment the page was loaded and not the current resource usage.
You can select how often Advanced Monitoring will auto-refresh its data
(for example, each five seconds or each hour)
or you can turn off auto-refresh and refresh the data manually by clicking the 
icon.
By default, Advanced Monitoring auto-refreshes its data every two minutes.
Note: Advanced Monitoring data does not change in real time.
If your server is permanently loaded,
you will not see the conformity between Advanced Monitoring
and a system resource usage monitor (for example, top in Linux or Task Manager in Windows).
You can also select a time period for which Advanced Monitoring will generate graphs
or specify a custom time period by selecting “Custom time range”.
This may help you find out how the parameters change with time and identify the time periods
when the resources usage is maximal or minimal.
