# The Monitoring Summary Dashboard

The Monitoring Summary includes a variety of panels that display monitoring information on the health and status of your managed products.

To view the monitoring summary, click Dashboard > Monitoring Summary.

## Total Number of Nodes

Each tile in the Total Number of Nodes panel displays the count of managed nodes of the specified type. These types are defined as follows.

Tile | Count
--- | ---
Devices | Devices which are forwarding events.
ArcMC/CHA | Includes managed ArcMCs and Connector Hosting Appliances, in both hardware and software form factors.
Connectors | Managed Connectors.
Collectors | Managed Collectors.
Loggers | Managed Loggers (hardware and software form factors).
Nodes | Nodes on the managed Transformation Hub. (Note that if Transformation Hub is upgraded, the Monitoring Summary will not reflect the correct Transformation Hub information until you import the new Transformation Hub certificate into ArcMC. See Downloading and Importing Host Certificates for more information.) Note: To display Transformation Hub Processing Data users need to turn on the C2AV pod on the Transformation Hub, for more information see Managing Transformation Hub through ArcMC. Event Parsing Error, Stream Processing EPS, and Stream Processing Lag are the metrics that will be available after the C2AV pod is turned on, otherwise only CPU Usage and Memory under Broker's Health will be displayed. Note: The stream processors metric name format has changed to SP_Name(SP_Type).

To see the details of a node type, click the title corresponding to the node type. For example, to view the details of all Collectors, click Collectors.

## Devices by Device Type

The Devices by Device Type display shows a color-coded sunburst of the various device types in use across your network. The table shows the total number of active and inactive devices by device product.

The inner ring of the sunburst shows the total devices.

The outer ring of the sunburst shows the total number of device types. For clarity of display, if the number of device types exceeds 1000, the outer ring is not shown.

The Devices Information for All Device Types table breaks down the information to display Device Type, Severity (Fatal, Critical, Warning, Healthy), and Total Devices.

To see the details of a device type, click the corresponding tile in the wheel, or its entry in the table.

Note: ArcMC 2.6 and 2.7 Device Monitoring function supports only Connectors 7.3 - 7.7. ArcMC 2.8 and later support Connectors 7.3 and later for Device Monitoring.

## Device Configuration for Device Type

The Device Configuration for Device Type page allows you to modify the Device Product time-out Interval, Device age-out Interval, and Disable Device Tracking.

Device Product time-out Interval

The default value is set to 20 minutes, this can be modified. If the selected device type does not send events to the connector during the last 20 minutes, the device type will be marked as Inactive.

Device age-out Interval

The default value is set to 14 days, this can be modified. If the selected device type remains inactive for 14 days, the device type records will be purged from the system.

Disable Device Tracking.

This box can be checked to disable the selected device product family.

Note: If device product monitoring is re-enabled X days later while Disable Device tracking is enabled, the aged-out internal should be set to Y days, in which Y comes after X days. This will prevent the selected disable tracking product family device records from being removed of the ArcMC system.

## Device Health Metrics

The dashboard displays device health information as severity. The Sunburst Chart shows the Severity as "HEALTHY", "FATAL", "WARNING", or "CRITICAL".

Note: The selection and layout of the panels on the Monitoring Summary is not customizable. You can, however, customize the issues reported for a given node type by creating custom breach rules, which can be viewed on the Severity Issue Summary. See Monitoring Rules
