View MongoDB Processes

To view the metrics for a specific MongoDB process in a Cloud Manager deployment, click on that process from the Deployment view. The Cloud Manager process view displays three tabs for monitoring metrics for the process:

  • The Status tab displays the process metrics Cloud Manager collects from the selected mongod or mongos process.
  • The Hardware tab displays hardware metrics for the host machine supporting the selected mongod or mongos process.
  • The DB Stats tab displays the database metrics for the selected database.

Monitor deployment metrics to identify performance issues and determine whether your current deployment meets your requirements. To learn more about the metrics available to monitor your deployments, see Review Available Metrics.

Cloud Manager retrieves database metrics every 20 minutes by default but adjusts frequency when necessary to reduce the impact on database performance. If the collection of database statistics still affects performance, you can disable collection by clicking Settings from the left-hand navigation, then Project Settings, and then setting Collect Database Specific Statistics to No.

The view for each tab has three distinct sections:

Chart Controls

Cloud Manager provides the following controls for the Status, Hardware, and DB Stats views. Adjusting any of these options affects all charts displayed under the selected view:

Control Function
Granularity Modifies the granularity of metrics displayed for each chart. Select a granularity between 1 minute and 1 day (24 hours). Select Auto to automatically adjust the granularity based on the selected Zoom or Current Display date controls. Auto granularity selects the highest fidelity granularity available for the time range.
Zoom Modifies the date range of metrics displayed for each chart. Select a zoom range between 1 hour and 5 years. Adjusting the Zoom automatically adjusts the Current Display date range.
Current Display Modifies the start and end date-time range of metrics displayed for each chart. Modifying the start and end date sets the value of Zoom to custom and overrides the previously selected zoom level.
Add Chart Select one or more charts to display or hide. Adding charts using this dropdown is identical to adding charts from the Toggle Charts section of the Metrics view.
Select Database Only visible for the DB Stats view. Selects the database for which to display metrics.
Display Opcounters on Separate Charts Directs Cloud Manager to split the Opcounters chart into its individual components. You can then choose to chart one or more of those components.
Display Timeline Annotations Directs Cloud Manager to display or hide chart annotations. Chart annotations consist of colored vertical lines that indicate server events, such as a server restart or a transition in member state.

Chart Display

When viewing charts, you can do the following:

Task Action
View a detailed description of a chart.

Expand a chart.

Hover your mouse over the chart to display the context menu.

Click the two-way arrow at the top right of the chart.

Click and drag the mouse pointer over a portion of the chart.

To reset to the originally selected range (zoom out), double-click the chart.

When you zoom in on a period of time, the Current Display date range in the chart control section automatically updates to reflect the selected period.

View statistics at a particular time. Hover the mouse pointer over a point on the chart.
Move a chart. Click and hold the grabber in the upper left corner of the chart, and drag the chart to the new position.
Share a URL to the chart.

Hover your mouse over the chart to display the context menu.

Click the curved arrow on the chart. Select Chart Permalink to retrieve a URL to the chart. Select Email Chart to e-mail the chart.

The recipient of the chart URL must have a Cloud Manager user account with access to the project and deployment.

Cloud Manager displays the available metrics to chart for the selected deployment under the Toggle Charts header.

  • Charts marked with plus icon are inactive.
  • Charts marked with minus icon are active.

Click on any chart to toggle the chart state.
