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
