Tekton Exporter

A Prometheus Exporter to collect and expose some useful fine-grained Tekton metrics that are not exposed natively

Motivation

In our platform team, we needed to build some useful dashboards to show our developers the status of the pipelines per project to make them compete for the first position on the reliability podium.

There are some metrics that are not exposed, which are necessary to achieve our goal, so we decided to create this small tool.

Flags

Every configuration parameter can be defined by flags that can be passed to the CLI. They are described in the following table:

Name	Description	Default Example
--log-level	Define the verbosity of the logs	info	--log-level info
--disable-trace	Disable traces from logs	false	--disable-trace true
--kubeconfig	Path to kubeconfig	-	--kubeconfig="~/.kube/config"
--metrics-port	Port where metrics web-server will run	2112	--metrics-port 9090
--metrics-host	Host where metrics web-server will run	0.0.0.0	--metrics-host 10.10.10.1
--populated-labels	(Repeatable or comma-separated list) Object labels populated on metrics	-	--populated-labels "apiVersion,pipelineName,projectName"

For Prometheus SDK, it is mandatory to register the metrics before using them. Due to this, if you use --populated-labels flag and the label is not present in some PipelineRun or TaskRun the label will be populated with # as value

Examples

Here you have a complete example to use this command.

Output is thrown always in JSON as it is more suitable for automations

tekton-exporter run \
    --log-level=info
    --kubeconfig="./path"

ATTENTION: If you detect some mistake on the examples, open an issue to fix it. This way we all will benefit

How to use

This project provides binary files and Docker images to make it easy to use wherever wanted

Binaries

Binary files for the most popular platforms will be added to the releases

Docker

Docker images can be found in GitHub's packages related to this repository

Do you need it in a different container registry? We think this is not needed, but if we're wrong, please, let's discuss it in the best place for that: an issue

Exposed metrics

This project is about exposing useful metrics related to the status of the Pipelines and Tasks, so, what about them?

Name	Description	Metric labels
tekton_exporter_pipelinerun_status	Status of a PipelineRun	name, namespace, status, reason
tekton_exporter_taskrun_status	Status of a TaskRun	name, namespace, status, reason
tekton_exporter_pipelinerun_duration_seconds	Seconds lasted by a PipelineRun	name, namespace, start_timestamp, completion_timestamp
tekton_exporter_taskrun_duration_seconds	Seconds lasted by a TaskRun	name, namespace, start_timestamp, completion_timestamp

How to contribute

We are open to external collaborations for this project: improvements, bugfixes, whatever.

For doing it, open an issue to discuss the need of the changes, then:

• Fork the repository
• Make your changes to the code
• Open a PR and wait for review

The code will be reviewed and tested (always)

We are developers and hate bad code. For that reason we ask you the highest quality on each line of code to improve this project on each iteration.
