Value can be none, auto, localsyslog, rfc5424, journal, json Value can be none, text, jsonĮnables local logging. FieldĮnables logging to standard streams. The below table summarizes all the options supported. The self-hosted gateway also supports a number of protocols including localsyslog, rfc5424, and journal. If your self-hosted gateway is deployed in Azure Kubernetes Service, you can enable Azure Monitor for containers to collect stdout and stderr from your workloads and view the logs in Log Analytics. You can easily view the logs using the following command: kubectl logs The self-hosted gateway outputs logs to stdout and stderr by default. Number of milliseconds spent on overall client IO (connecting, sending and receiving bytes) Number of milliseconds spent on overall backend IO (connecting, sending and receiving bytes) Number of milliseconds from the moment gateway received request until the moment response sent in full Make some API calls through the self-hosted gateway, if everything is configured correctly, you should be able to view below metrics: Metric Go to the Prometheus dashboard using the EXTERNAL-IP and PORT of the Prometheus Service. Prometheus will pick up the metrics from StatsD. Now we have everything deployed and configured, the self-hosted gateway should report metrics via StatsD. To pick up the latest configuration changes, restart the gateway deployment using the below command: kubectl rollout restart deployment/ Update the YAML file of the self-hosted gateway deployment with the above configurations and apply the changes using the below command: kubectl apply -f. Here is a sample configuration: apiVersion: v1 Value can be none, librato, dogStatsD, influxDB. Below is a breakdown of the available options: FieldĮnables logging through StatsD. The feature can be enabled or disabled using the key in the ConfigMap of the self-hosted gateway Deployment with additional options. Now that both StatsD and Prometheus have been deployed, we can update the configurations of the self-hosted gateway to start emitting metrics through StatsD. Sputnik-metrics-statsd NodePort 10.0.41.179 8125:32733/UDP 18hĬonfigure the self-hosted gateway to emit metrics NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE You can visit the Prometheus dashboard using its EXTERNAL-IP and PORT. Take a note of the CLUSTER-IP and PORT of the StatsD Service, we would need it later. Run the below command to check the Services are running. ![]() Note that your pod name will be different. Once the deployment finishes, run the below command to check the Pods are running. Save the configurations to a file named metrics.yaml and use the below command to deploy everything to the cluster: kubectl apply -f metrics.yaml Learn more about working with public images. To improve reliability when working with public content, import and manage the images in a private Azure container registry. We recommend that you set up a pull secret to authenticate using a Docker Hub account instead of making an anonymous pull request. ![]() The following example pulls public container images from Docker Hub. ![]()
