Jenkins Infra Datadog monitoring

Table of Contents

This repository is meant to hold configuration files of Jenkins infrastructure monitoring stuff.

This repository hosts the infrastructure-as-code definition for all the DataDog monitoring resources for the Jenkins Infrastructure Project.

Requirements

An access to the Jenkins Datadog account for the Jenkins Infrastructure at https://jenkins.datadoghq.com.
The requirements (of the shared tools) listed at shared-tools/terraform#requirements
The Terraform AzureRM Backend Configuration on a local file named backend-config:
- The content can be retrieved from the credentials of infra.ci.jenkins.io.
- This file (backend-config) is git-ignored
The git command line to allow cloning the repository and its submodule shared-tools
- This repository has submodules. Once you cloned the repository, execute the following command to obtain the shared tools:

git submodule update --init --recursive

DataDog monitors are configured through Terraform with the datadog provider.

Once you’ve fulfilled the Requirements, you may execute any command from https://github.com/jenkins-infra/shared-tools/blob/main/terraform/README.adoc#available-commands by adding the correct flag --directory pointing to .shared-tools/terraform/:

make --directory=.shared-tools/terraform help
make --directory=.shared-tools/terraform lint
# ...

A usual change (add/update/remove a datadog monitor for instance) to this repository looks like the following:

Fork the repository and clone it locally
Follow the Requirements steps to obtain the shared tools
Start by running a full make --directory=.shared-tools/terraform validate command to ensure that you work on a sane base (should generate a report TXT file with no changes to be applied)
Edit the Terraform project files
Run the command make --directory=.shared-tools/terraform validate again to ensure that your changes are OK
Commit, push and open a pull request to let the Jenkins pipeline run the test + plan (as per https://github.com/jenkins-infra/shared-tools/blob/main/terraform/README.adoc#jenkins-pipeline)
