Cluster Management - WunderGraph

Routers

Cluster overview

The list displays all running router instances. Upon closer inspection, you can verify the currently deployed graph composition and vital metrics such as CPU and memory utilization. Here is a summary of all provided information:

• Name: The application name specified under the TELEMETRY_SERVICE_NAME option. By default, it is set to cosmo-router. Below we show the hostname where the router is running on.
• Instance ID: If not specified as INSTANCE_ID environment variable, a new ID will be generated with each router start. A stable ID ensures that metrics with the same ID are grouped together and no new router appears.
• Status: Identify if the server is up and running. In the future, we will conduct advanced validation that takes various metrics into consideration.
• Version: The deployed binary version of the router.
• Cluster: The logical cluster name. Is specified by the CLUSTER_NAME environment variable. By default, it is an empty string.
• Uptime: The duration indicates how long the process has been operational. By clicking on details, you can view the server’s uptime as well. Typically, this time represents how long a specific version of the graph has been running when polling from the controlplane is enabled.
• Mem / CPU: The utilization of the router instance. Arrows signal the trend between two data samples.

If your router fails to push uptime metrics for any reason, the instance will disappear. As long as one metric sample reaches us within 45 seconds, we assume the router is operational.

Instance details

If you click on a router instance, a summary displaying all the metrics available for your router instance will be shown. We will reserve this space to add additional metrics and diagrams in the future. If you have any ideas or requirements, please don’t hesitate to make a feature request.
