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
|

||
|
|
$ ./metrics URL > et-2720.$$
|
