View Replica Set Deployments

A replica set in MongoDB is a group of mongod processes that maintain the same data set. To view the metrics for a specific Ops Manager replica set deployment in a project, click the Metrics button for that deployment. Alternatively, click on the name of the deployment to open the deployment overview, then click the Metrics tab.

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.

The Metrics view has three distinct sections:

Chart Controls

Ops Manager provides the following controls for the Metric view. Adjusting any of these options affects all charts displayed under the Metrics 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.
Toggle Members Limit charts to the selected replica set members. The P icon represents the primary replica set member, while the S icon represents a secondary member.
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.
Display Opcounters on Separate Charts Directs Ops 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 Ops 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.

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

Click the i icon next to the chart name to open the Chart Info modal. This modal includes a breakdown of the chart’s data series, the annotations available for that chart, and the operations the chart supports.

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.

Zoom in on a period of time.

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 an Ops Manager user account with access to the project and deployment.

Chart Selection

Ops Manager displays the available metrics to chart for the selected deployment under the Toggle Charts header. Metrics are grouped into two sections:

MongoDB Metrics

Metrics associated with the MongoDB process. For metrics related to database performance, such as DB Storage, Ops Manager presents the sum total across all databases in the deployment.

If you enable Display Opcounters on Separate Charts, Ops Manager replaces the Opcounters option with the individual components of that chart.

Hardware Metrics

Metrics associated with the host machines supporting the deployment.

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

Click on any chart to toggle the chart state.
