Datadog Backup File Check

Simple Datadog check to measure the age of the most recent file in hours. Used for checking and alerting on the presence of a recent backup.

Installation

• Copy the check script (newest_file_age.py) from this repo to /etc/datadog-agent/check.d/newest_file_age.py
• Copy the config file (newest_file_age.yaml) from this repo to /etc/datadog-agent/conf.d/newest_file_age.yaml
• Amend newest_file_age.yaml for the directory you would like to check
• Restart the datadog agent

sudo systemctl restart datadog-agent

• Test with:

sudo -u dd-agent -- datadog-agent check newest_file_age

• Check the Datadog UI for metrics
• Amend the check as needed if you prefer more frequent checks or checks based on seconds
• On the Datadog UI create a monitor to alert when the newest_file_age.hours exceeds your preferred threshold
