System Statistics

The System Statistics view provides real-time visibility over the main Clarive processes. It is available from the menu Admin Area → System → System Statistics and requires the action.help.server_info permission.

Overview

The dashboard renders two timelines using the built-in C3 charting library:

  • Memory over time – displays the total memory usage (MB) per sample.
  • CPU over time – displays the total CPU percentage per sample.

The information is read from the clarive_stats collection, which is periodically populated by the dispatcher, web server and daemon services.

Filters

Use the controls at the top of the page to refine the dataset:

  • Key – logical identifier sent when saving the metric. The select accepts more than one key; every chosen key is plotted as a dedicated line on the charts. The entry labelled “(no key)” represents stats saved without an explicit key. Leave the field empty to display all available keys.
  • Process name – executable name reported by the process.
  • Hostname – origin host.
  • Instance ID – Clarive instance identifier.
  • PID – operating system process id.
  • Date range – start and end timestamps (defaults to the last hour).
  • Limit – cap the maximum number of samples retrieved (default 500, max 2000).

After adjusting any filter, click Apply to refresh the charts. Use Reset to restore the default view. When multiple keys are selected the charts render one line per key so you can compare processes side by side.

Auto-refresh

An auto-refresh selector allows refreshing the charts automatically at 1s, 2s, 5s, 15s or 30s intervals. Select Off to disable automatic updates. The Refresh now button always triggers an immediate data reload.

The latest sample information (sample count and timestamp) is displayed above the charts.
