Observability


builds for Red Hat OpenShift 1.6

Build controller observability

Red Hat OpenShift Documentation Team

Abstract

This document provides information about build controller observability.

Chapter 1. Logging

When a build fails or behaves unexpectedly, accessing detailed logs can help you identify the issue. The logs provide information about what happened during the build run.

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 oc CLI.
  • Optional: You have installed the shp CLI.

Procedure

  • View logs of a build run by using one of the CLIs:

    Using oc CLI

    $ oc logs <buildrun_resource_name>
    Copy to Clipboard Toggle word wrap

    Using shp CLI

    $ shp buildrun logs <buildrun_resource_name>
    Copy to Clipboard Toggle word wrap

Chapter 2. Monitoring

Builds exposes several metrics to help you monitor the performance and functioning of your build resources. The build controller metrics are exposed on the port 8383.

2.1. Build controller metrics

You can check the following build controller metrics for monitoring purposes:

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:
