Observability
Build controller observability
Abstract
Chapter 1. Logging
As a developer, detailed logs are essential for diagnosing issues when a build fails or behaves unexpectedly. Logs provide information about what happened during the build. If logs do not show the error, you can check the build controller or histogram metrics to troubleshoot the issue.
1.1. Viewing logs
You can view the logs of a build run to identify any runtime errors and to resolve them.
Prerequisites
-
You have installed the
ocCLI. -
Optional: You have installed the
shpCLI.
Procedure
View logs of a build run. You can do so by using the
ocCLI or theshpCLI.oc logs <buildrun_resource_name>
$ oc logs <buildrun_resource_name>Copy to Clipboard Copied! Toggle word wrap Toggle overflow shp buildrun logs <buildrun_resource_name>
$ shp buildrun logs <buildrun_resource_name>Copy to Clipboard Copied! Toggle word wrap Toggle overflow
Chapter 2. Monitoring
Builds exposes several metrics for cluster administrators to monitor the performance and functioning of your build resources. The build controller metrics are exposed on port 8383.
2.1. Builds controller metrics
Builds controller metrics expose the internal state and activity of the builds controller in OpenShift Container Platform.
Red Hat does not provide support for the builds controller metrics.
You can check the following builds controller metrics for monitoring purposes:
| Name | Type | Description | Labels | Status |
|---|---|---|---|---|
|
| Counter | The number of total registered builds. |
| experimental |
|
| Counter | The number of total completed build runs. |
| experimental |
|
| Histogram | The build run establish duration in seconds. |
| experimental |
|
| Histogram | The build run completion duration in seconds. |
| experimental |
|
| Histogram | The build run ramp-up duration in seconds. |
| experimental |
|
| Histogram | The build run ramp-up duration for a task run in seconds. |
| experimental |
|
| Histogram | The build run ramp-up duration for a task run pod in seconds. |
| experimental |
2.1.1. Histogram metrics
To use custom buckets for the build controller, you must set the environment variable for a particular histogram metric. The following table shows the environment variables for all histogram metrics:
| Metric | Environment variable | Default |
