This gist contains various scripts for scraping metrics. Mostly useful for processing the contents of Puppet Enterprise support bundles:

sar2influx.rb: A Ruby script that uses sadf to turn SAR archives into InfluxDB line format. For best results, run from a Linux VM using a recent operating system. Such as Ubuntu 22.04.
pdb2influx.sh: A bash script that uses awk and mlr to extract command processing times from puppetdb.log files.
top-api-calls.sh: Extracts the 10 most popular API calls from *-access.log along with their median and max duration grouped into 30 minute periods (Puppet $runinterval). Uses awk and mlr.

	// Abstract:
	// This script is just a quick hack to export the owners and members of a team as a CSV file without administrator permissions.
	//
	// Usage:
	// 1. Open your team
	// 2. Select "Manage team" from its menu
	// 3. Select the "Members" tab
	// 4. Expand the "Owners" and "Members and guests" sections
	// 5. Make sure to scroll down to the end of the owners and members lists to include all of them in your export (As the members are loaded on demand)
