good way to document

For basic requirements, you can create a bash script which invokes

tmsh list

commands and parses the output according to your preference. Every now and then, execute the script manually, and also manually update the documentation in your corporate Sharepoint (or w/e you have). This is a low-cost solution.

In case of complex requirements where real-time visibility of current config and/or system metrics are required 24/7, no manual solution will work. This is where companies turn to API (REST). Also a front-end component other than F5 must be used (this can be any NIX/Apache server). A Typical F5 visibility automation project from start to finish will cost a company anywhere from 50k-200k USD, regardless if internal employees or external contractors are used for the job.

Also note there are a few iApps and other visibility tools F5 offers for free. One example being the F5 and Splunk Analytics collaboration (https://splunkbase.splunk.com/app/3161/). Before building a custom tool, it's advised to check whether any of the freely available tools cover your needs.
