Grafana is an open-source monitoring solution that can be used to configure visual dashboards for Dubbo, allowing you to monitor the health of your Dubbo cluster.
Here are the default metrics dashboards provided by the Dubbo community. You can quickly use them after configuring the data source and importing directly. If the default dashboards do not meet your requirements, you can customize your Grafana dashboards.
You can quickly import Grafana monitoring dashboards in the following ways.
You can quickly install Grafana using the sample configuration provided by the Dubbo community, which comes with the default community metrics dashboards.
kubectl create -f https://raw.githubusercontent.com/apache/dubbo-kubernetes/master/deploy/kubernetes/grafana.yaml
You may need to port-forward to access it: $ kubectl port-forward service/grafana 3000:3000, then open the browser and visit http://localhost:3000.
Retrieve login information
kubectl get secrets grafana -o jsonpath="{.data.admin-user}" | base64 --decode ; echo && kubectl get secrets grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo
If you already have Grafana installed, you can import the dashboard via the import menu in the Grafana console. The Prometheus data source address must also be specified during the import process.
You can also use the following script for quick importing.
$ # Address of Grafana
$ GRAFANA_HOST="http://localhost:3000"
$ # Login credentials, if authentication is used
$ GRAFANA_CRED="USER:PASSWORD"
$ # The name of the Prometheus data source to use
$ GRAFANA_DATASOURCE="Prometheus"
$ # The version of Dubbo to deploy
$ VERSION=3.2.0
$ # Import all Dubbo dashboards
$ for DASHBOARD in 18469 4701; do
$ #REVISION="$(curl -s https://grafana.com/api/dashboards/${DASHBOARD}/revisions -s | jq ".items[] | select(.description | contains(\"${VERSION}\")) | .revision")"
$ REVISION=1
$ curl -s https://grafana.com/api/dashboards/${DASHBOARD}/revisions/${REVISION}/download > /tmp/dashboard.json
$ echo "Importing $(cat /tmp/dashboard.json | jq -r '.title') (revision ${REVISION}, id ${DASHBOARD})..."
$ curl -s -k -u "$GRAFANA_CRED" -XPOST \
$ -H "Accept: application/json" \
$ -H "Content-Type: application/json" \
$ -d "{\"dashboard\":$(cat /tmp/dashboard.json),\"overwrite\":true, \
$ \"inputs\":[{\"name\":\"DS_PROMETHEUS\",\"type\":\"datasource\", \
$ \"pluginId\":\"prometheus\",\"value\":\"$GRAFANA_DATASOURCE\"}]}" \
$ $GRAFANA_HOST/api/dashboards/import
$ echo -e "\nDone\n"
$ done
Grafana can be installed and configured through other methods; refer to the documentation on installation methods to learn how to create and import Dubbo monitoring dashboards.
