Google Cloud Service Mesh monitoring integration

Monitor your Google Cloud Service Mesh resources to track connected Envoy proxy clients and xDS configuration request volumes across zones. Google Cloud Service Mesh monitor lets you maintain visibility into your service mesh control plane.

Benefits

Monitoring Cloud Service Mesh ensures that your service remains reliable, secure, and high-performing. Key benefits include:

Identify disconnected proxy clients or control plane overload before they impact traffic routing.
Track xDS request volumes by zone to fine-tune control plane capacity.
Receive automated alerts and use IT automation to maintain SLA compliance and reduce downtime.
Consolidate Cloud Service Mesh metrics with other Google Cloud Platform services for a single pane of glass view.
Rest assured that bulk configuration and agent upgrades ensure smooth monitoring across multiple mesh deployments.

Use cases

Here are some use cases where Google Cloud Service Mesh monitoring will be helpful:

Monitor connected client counts to detect proxy disconnections in real time.
Capture xDS request count trends to quickly identify control plane load spikes.
Visualize request distribution by zone to plan capacity and optimize scaling.
Set thresholds for connected client counts to ensure contractual obligations are met.
Track per-zone request patterns to strengthen multi-region mesh reliability.
Integrate Cloud Service Mesh monitoring with other Google Cloud Platform services (e.g., GKE, Compute Engine, Cloud Run) for holistic visibility.

Setup and configuration

Adding Google Cloud Service Mesh while configuring a new Google Cloud monitor

If you have not configured a Google Cloud monitor yet, add one by following the steps below:
1. Go to Cloud > GCP > Add GCP Monitor or Admin > Cloud Monitoring > Google Cloud Platform (GCP).
2. Provide a unique display name for identification purposes.
3. Upload the JSON file that contains the private key of the service account to authenticate and perform resource discovery.
4. Select Cloud Service Mesh from the Select the Resources for Monitoring list.
5. Select existing Notification Profiles, User Alerts Groups, Tags, and IT Automation Templates or add new ones. You can also integrate alarms with your preferred third-party service.
6. Click Start GCP Monitoring.
Adding Google Cloud Service Mesh to an existing Google Cloud monitor

If you already have a Google Cloud monitor configured for the service account, you can add Google Cloud Service Mesh by following the steps below:
1. Go to Cloud > GCP and select your Google Cloud Platform monitor.
2. Click the hamburger icon next to Service View and select Edit, which brings you to the Edit GCP Monitor page.
3. On the Edit GCP Monitor page, select Cloud Service Mesh from the Select the Resources for Monitoring list and click Save.
4. After successful configuration, go to Cloud > GCP > Cloud Service Mesh. Now you can view the discovered Google Cloud Service Mesh resources.

Note

It will take approximately five minutes to discover new Google Cloud Platform resources.

Licensing

Each Google Cloud Service Mesh monitor consumes one basic monitor license.

Polling frequency

Google Cloud Service Mesh monitor collects minute-wise metric data, and the statuses of your Google Cloud Service Mesh resources are reported every five minutes.

Supported metrics

Metric name	Description	Statistic	Unit
Connected Clients	The number of Envoy proxy clients currently connected to the xDS control plane.	Average	Count
Request Count	The number of xDS configuration requests received by the control plane from connected clients.	Total	Count
Request Count By Zone	The number of xDS configuration requests received by the control plane, grouped by client zone.	Total	Count

Threshold configuration

Global configuration
1. In the web client, go to the Admin section on the left navigation pane.
2. Select Configuration Profiles from the left pane, then select Threshold and Availability from the drop-down menu.
3. Click Add Threshold Profile in the top-right corner.
4. For Monitor Type, select Cloud Service Mesh.
5. Specify the threshold values for the required metrics, then click Save.
Monitor-level configuration
1. In the web client, go to Cloud > GCP > Cloud Service Mesh.
2. Select a resource you would like to set a threshold for, then click the hamburger icon.
3. Select Edit, which directs you to the Edit Cloud Service Mesh Monitor page.
4. Specify the threshold values for the required metrics, then click Save.

IT Automation

IT Automation tools automatically resolve performance degradation issues. These tools react to events proactively rather than waiting for manual intervention. The IT Automation tools automate repetitive tasks and automatically remediate threshold breaches. The alarm engine continually evaluates system events for which thresholds are set and executes the mapped automation when there is a breach.

Configuration Rules

Editing multiple monitors to associate different monitor groups or add a different tag can be a tedious process. With Configuration Rules, you can automate the configuration settings of your monitoring resources. Create custom rules to track configuration changes continuously and achieve the ideal configuration settings.
