A Prometheus Exporter to collect and expose some useful fine-grained Tekton metrics that are not exposed natively
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.
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-labelsflag and the label is not present in some PipelineRun or TaskRun the label will be populated with#as value
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
This project provides binary files and Docker images to make it easy to use wherever wanted
Binary files for the most popular platforms will be added to the releases
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
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 |
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.
