Usage monitoring

Usage monitoring

We recommend monitoring your Coder deployment to track compute cost, performance, uptime, and deployment stability. Because you deploy Coder onto Kubernetes clusters, you can monitor your developer workspaces as you would any other server workload.

Node utilization metrics

One of the most important metrics to track is the CPU and memory usage/utilization of the underlying Kubernetes node. Excessive node resource contention can result in the throttling of developer workspaces, while excessive underutilization suggests that you may be spending more on your cloud workspace than necessary.

Monitoring CPU utilization

Monitoring Memory utilization

There are several tools available to you to balance the tradeoff between workspace performance and cloud cost. Read more about this on compute resources.

Development workspace metrics

Coder comes with a set of Kubernetes labels that allow monitoring tools to map cluster resources to Coder's product-level resource identifiers. For example, the following chart tracks the CPU/Memory Limit Utilization of each workspace container and labels them with the username and workspace name identifiers:

Monitoring CPU Utilization by workspace and user

Monitoring Memory Utilization by workspace and user

These views can help you track which users may require larger CPU allocations, enabling greater "burst-ability" under peak loads. However, remember that using a CPU/memory provision rate greater than 1:1 may result in users being throttled below their CPU limit if the underlying Kubernetes Node experiences CPU contention.

Control plane monitoring

Monitoring the Coder control plane can help you maintain high uptime. For example, the following charts provide high-level insight into the state of the Coder API server:

Monitoring log event severity

Monitoring API status codes

Monitoring HTTP latency
