Monitoring a Service Graph

Monitoring a Service Graph Instance Using the GUI

After you configure a service graph template and attach the graph to an endpoint group (EPG) and a contract, you can monitor the service graph instance. Monitoring includes viewing the state of the graph instances, functions of a graph instance, resources allocated to a function, and parameters specified for a function.

Procedure

Step 1

On the menu bar, choose Tenants > All Tenants.

Step 2

In the Work pane, double click the tenant's name for which you want to monitor its service graph.

Step 3

In the Navigation pane, choose Tenant tenant_name > Services > L4-L7 > Deployed Graph Instances. The Work pane displays the following information about the active service graph instances:

Name

Description

Service Graph column

The name of the service graph template.

Contract column

The name of the contract that is shown in the service graph template.

Contained By column

The name of the network that contains the service graph template.

State column

The state of the service graph template. A state of applied means that the graph has been applied, and the graph policy is active within the fabric and the service device.

Description column

The description of the service graph.

Step 4

Expand the Deployed Service Graphs branch. The active service graph instances are listed under the branch.

Step 5

Click a service graph instance to view additional information about that instance in the Work pane. The default view is the topology of the graph. You can click one of the tabs in the Work pane to change the view for that graph.

Step 6

Expand the branch for one of the graph instances. The functions of the graph instance are listed under the instance.

Step 7

Click one of the functions to view additional information about that function in the Work pane. The default view is the policy of that function. You can click one of the tabs in the Work pane to change the view for that function. The Work pane displays the following information about the policy:

Name Description
POLICY tab The function's properties, resources allocated to the function, and the parameters of the function.
FAULTS tab The issues that are happening on the function node.
HISTORY tab The history of events that occurred on the function node.

Step 8

In the Navigation pane, click Deployed Device. The Work pane displays information about the device instances.

Monitoring Service Graph Faults Using the GUI

After you configure a service graph template and attach the graph to an endpoint group (EPG) and a contract, you can monitor a service graph template's faults.

Procedure

Step 1

On the menu bar, choose Tenants > All Tenants.

Step 2

In the Work pane, double click the tenant's name for which you want to monitor its service graph.

Step 3

In the Navigation pane, choose Tenant tenant_name > Services > L4-L7 > Deployed Graph Instances.

Step 4

Expand the branch for a graph instance for which you want to view its faults. The functions of the graph instance are listed under the instance.

Step 5

Click on one of the functions. By default, the Work pane shows the policy of that function.

Step 6

Click the FAULTS tab in the Work pane. The Work pane displays the faults of the function node.

Resolving Service Graph Faults

After you have observed one or more service graph template faults, resolving the issue depends on the fault. The following tables describe the faults and provide how to resolve faults.

Monitoring a Virtual Device Using the GUI

After you configure a service graph template and attach the graph to an endpoint group (EPG) and a contract, you can monitor the virtual devices of a tenant. Monitoring the virtual devices tells you what devices are in use, which VLANs are configured for a device, the parameters passed to the devices, the statistics of the devices, and the health of the devices.

Procedure

Step 1

On the menu bar, choose Tenants > All Tenants.

Step 2

In the Work pane, double click the tenant's name for which you want to monitor its service graph.

Step 3

In the Navigation pane, choose Tenant tenant_name > Services > L4-L7 > Deployed Devices.

Step 4

Click on one of the deployed devices. By default, the Work pane shows the policy of that deployed device. You can click the tabs in the Work pane to change the view. The tabs display the following information about the virtual device:

Tab

Description

POLICY tab

The device that is in use, the VLANs that are configured within the device, and the parameters that have been passed to the devices.

OPERATIONAL tab

The statistics that are being received from the various devices.

HEALTH tab

The health of the devices.
