prom.awk: New basic library 
This introduces the beginning of a very basic library for generating
Prometheus metrics with GNU Awk.  It is not intended to be complete, and
it'll evolve as I need it to.

At the moment, there are no tests, because manual verification is
trivial and I'm not yet sure how far I'll be going with this.  If it
evolves much further, though, I'll be adding a test suite.

Epson ET-2720 Metrics

The Epson ET-2720 is a tank printer. It has a web interface that can be used to review printer status. The relevant sections do not require authentication.

This script produces the following metrics:

  • printer_pages_count with the number of pages for copies, scans, printing, and internal operations (like diagnostic pages);
  • printer_ink_level for CYMK ink tank levels;
  • printer_scrape_time_seconds for the timestamp of the last scrape; and
  • printer_scrape_duration_seconds for the number of seconds spent scraping (yes, sorry, this is an integer value and will likely be 0 most of the time).

How To Use

Simply provide the URL to the web interface:

# Generate metrics
$ ./metrics URL > et-2720.$$

# Atomic move to avoid Prometheus reading incomplete writes
$ mv et-2720.$$ et-2720.prom
