Documentation Grafana Agent Static mode Kubernetes operator Set up integrations

Set up integrations

This topic provides examples of setting up Grafana Agent Operator integrations, including node_exporter and mysqld_exporter.

Before you begin

Before you begin, make sure that you have deployed the Grafana Agent Operator CRDs and installed Agent Operator into your cluster. See Install Grafana Agent Operator with Helm or Install Grafana Agent Operator for instructions.

Also, make sure that you deploy the GrafanaAgent resource and the yaml you use has the integrations definition under spec.

Important: The field name under the spec section of the manifest must contain the name of the integration to be installed according to the list of integrations defined here.

Important: The value of the metrics_instance field needs to be in the format <namespace>/<name>, with namespace and name matching the values defined in the metadata section from the MetricsInstance resource as explained in deploy a MetricsInstance resource

Set up an Agent Operator node_exporter integration

The Agent Operator node_exporter integration lets you monitor your hardware and OS metrics from Unix-based machines, including Linux machines.

To set up a node_exporter integration:

1. Copy the following manifest to a file:

   yaml Copy

   apiVersion: monitoring.grafana.com/v1alpha1
   kind: Integration
   metadata:
    name: node-exporter
    namespace: default
    labels:
      agent: grafana-agent-integrations
   spec:
    name: node_exporter
    type:
      allNodes: true
      unique: true
    config:
      autoscrape:
        enable: true
        metrics_instance: default/primary
      rootfs_path: /default/node_exporter/rootfs
      sysfs_path: /default/node_exporter/sys
      procfs_path: /default/node_exporter/proc
    volumeMounts:
      - mountPath: /default/node_exporter/proc
        name: proc
      - mountPath: /default/node_exporter/sys
        name: sys
      - mountPath: /default/node_exporter/rootfs
        name: root
    volumes:
      - name: proc
        hostPath:
          path: /proc
      - name: sys
        hostPath:
          path: /sys
      - name: root
        hostPath:
          path: /root

2. Customize the manifest as needed and roll it out to your cluster using kubectl apply -f followed by the filename.

   The manifest causes Agent Operator to create an instance of a grafana-agent-integrations-deploy resource that exports Node metrics.

Set up an Agent Operator mysqld_exporter integration

The Agent Operator mysqld_exporter integration is an embedded version of mysqld_exporter that lets you collect metrics from MySQL servers.

To set up a mysqld_exporter integration:

1. Copy the following manifest to a file:

   yaml Copy

   apiVersion: monitoring.grafana.com/v1alpha1
   kind: Integration
   metadata:
    name: mysqld-exporter
    namespace: default
    labels:
      agent: grafana-agent-integrations
   spec:
    name: mysql
    type:
      allNodes: true
      unique: true
    config:
      autoscrape:
        enable: true
        metrics_instance: default/primary
      data_source_name: root@(server-a:3306)/

2. Customize the manifest as needed and roll it out to your cluster using kubectl apply -f followed by the filename.

   The manifest causes Agent Operator to create an instance of a grafana-agent-integrations-deploy resource that exports MySQL metrics.
