Service Mesh Metrics

You monitor the health, capacity, and performance of Service Mesh by using metrics, alarms, and notifications.

This topic describes the metrics emitted by the metric namespace oci_servicemesh.

Overview

Metrics help you monitor Service Mesh resources.

Namespace
A namespace is a container for metrics. The namespace identifies the service sending the metrics. The namespace for Service Mesh is oci_servicemesh.
Metrics
Metrics are the fundamental concept in telemetry and monitoring. Metrics define a time-series set of datapoints. Each metric has a namespace, metric name, compartment identifier, one or more dimensions, and a unit of measure. Each datapoint has a timestamp, value, and count associated with it.
Dimensions
A dimension is a key-value pair that defines the characteristics associated with the metric. For example, resourceId is the OCID of the resource that was scanned.
Statistics
Statistics are metric data aggregations over specified periods of time. Aggregations are done using the namespace, metric name, dimensions, and the data point unit of measure within the time period specified.
Alarms
Alarms are used to automate operations monitoring and performance. An alarm tracks changes that occur over a specific time period and performs one or more defined actions, based on the rules defined for the metric.

Required IAM Policy

To monitor resources in Oracle Cloud Infrastructure, you must be given the required type of access. An IAM administrator must write the required policies whether you're using the Console or the REST API with an SDK, CLI, or other tool.

The policy must give you access to the monitoring services and the resources being monitored. If you get a "you don’t have permission" or an "unauthorized" message, confirm with your administrator the type of access you were granted. Also, ensure you are working in the correct compartment.

For more information on user authorizations for monitoring, see the Authentication and Authorization section for the related service:

Ingress Gateway Metrics

Service Mesh includes the following metrics and dimensions for ingress gateways.

  • resourceId: The OCID of the ingress gateway resource.
  • meshId: The OCID of the parent mesh resource for this ingress gateway resource.
  • meshComponent - "IngressGateway": The Service Mesh resource type.
Metric Metric Display Name Unit Description
ActiveProxyConnections Number of connected proxies count

The number of active connected proxies at any given time.

This metric is updated every minute.
OutdatedProxyConnections Number of outdated proxies count

The number of connected proxies not running the latest image version.

This metric is updated every minute.

Virtual Deployment Metrics

Service Mesh includes the following metrics and dimensions for virtual deployments.

  • resourceId: The OCID of the ingress gateway resource.
  • virtualDeploymentId: The OCID of the parent virtual service resource for this virtual deployment resource.
  • meshId: The OCID of the parent mesh resource for this virtual deployment resource.
  • meshComponent - "VirtualDeployment": The Service Mesh resource type.
Metric Metric Display Name Unit Description
ActiveProxyConnections Number of connected proxies count

The number of active connected proxies at any given time.

This metric is updated every minute.
OutdatedProxyConnections Number of outdated proxies count

The number of connected proxies not running the latest image version.

This metric is updated every minute.

Using the Console

View the metric charts for Service Mesh.

  1. In the Console, open the navigation menu and click Observability & Management. Under Monitoring, click Service Metrics.
  2. For Compartment, select the compartment that contains the mesh that you're interested in.
  3. For Metric namespace, select oci_servicemesh.
  4. Select a Metric name, Interval, and Statistic.

    For example, select the metric named ActiveProxyConnections and set Interval to 1 minute.

  5. (Optional) To view the raw data points for the selected metric, click Show Data Table.

The Service Metrics page dynamically updates to show charts for each metric emitted by the selected metric namespace.

Using the API

Use the following APIs for monitoring.

For information about using the API and signing requests, see REST APIs and Security Credentials. For information about SDKs, see Software Development Kits and Command Line Interface.
