View MongoDB Processes¶
On this page
To view the metrics for a specific MongoDB process in an Atlas cluster, click Databases in the top-left corner of Atlas, then click that process from the Database Deployments view. You can monitor different aspects of your cluster in one place focused on a process. For more information about the Database Deployments view, see View Database Deployment Details.
Monitor database deployment metrics to identify performance issues and determine whether your current database deployment meets your requirements. For more information on the metrics available to monitor your database deployments, see Review Available Metrics.
The Atlas process view displays three tabs for monitoring metrics for the process:
- The Status tab displays the process metrics Atlas
collects from the selected
mongodormongosprocess. - The Hardware tab displays hardware metrics for
the host machine supporting the selected
mongodormongosprocess. The DB Stats tab displays the database metrics for the selected database.
Atlas 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:
NoteMonitoring Data Storage GranularityAtlas stores metrics data at increasing granularity levels. For more information, see Monitoring Data Storage Granularity.
Chart Controls¶
Atlas 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, usually between 1 minute and 1 day (24
hours). Select Note Atlas supports a 10 second granularity only on |
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 Atlas 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 Atlas 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 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. Note When you zoom in on one 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 email the chart. The recipient of the chart URL must have a Atlas user account with access to the project and cluster. |
Chart Selection¶
Atlas displays the available metrics to chart for the selected cluster under the Toggle Charts header.
Charts marked with the + symbol are inactive,
while charts marked with the - symbol are active. Click
on any chart to toggle the chart state.
