Terraform module for Datadog Php Fpm

This module is part of a larger suite of modules that provide alerts in Datadog. Other modules can be found on the Terraform Registry

We have two base modules we use to standardise development of our Monitor Modules:

• generic monitor Used in 90% of our alerts
• service check monitor

Modules are generated with this tool: https://github.com/kabisa/datadog-terraform-generator

Module Variables

Monitors:

Monitor name	Default enabled	Priority	Query
Process Limit	True	2	sum(last_15m):sum:php_fpm.processes.max_reached{tag:xxx} by {host,service}.as_count() > 1

Getting started developing

pre-commit was used to do Terraform linting and validating.

Steps:

• Install pre-commit. E.g. brew install pre-commit.
• Run pre-commit install in this repo. (Every time you clone a repo with pre-commit enabled you will need to run the pre-commit install command)
• That’s it! Now every time you commit a code change (.tf file), the hooks in the hooks: config .pre-commit-config.yaml will execute.
