Building a prometheus exporter for ricoh-printer related information like toner level
You can install the exporter from this repository using the following command:
pip install git+https://github.com/psyinfra/prometheus-ricoh-printer-exporter
To run the exporter, you need to provide a configuration file using the .json format. A template file "config_example.json" can be found at top-level in this repository. This is the template:
{
"printer1_name": {
"url": "https://address.to.printer"
},
"printer2_name": {
"url": "https://address.to.printer"
}
}
You'll need a configuration file containing the names and URLs of the printers you want to scrape. A template can be found in the repository under the name of config_example.json
To test the exporter, you can host the script on your own machine:
prometheus_ricoh_printer_exporter -c <abspath to config file>(make sure you installed via pip)- (from another terminal)
curl 0.0.0.0:9840(default IP-address)
Running curl 0.0.0.0:9840 should give you an output of similar structure
like this:
# HELP ricoh_printer_level_percent black toner level in percent
# TYPE ricoh_printer_level_percent gauge
ricoh_printer_level_percent{color="black",printer_name="oak"} 50.0
(The output should be similar for other data points, i.e. cyan)
usage: prometheus_ricoh_printer_exporter [-h] [-w LISTEN_ADDRESS] [-i] -c CONFIG
Set up the Prometheus exporter (connection ports)
options:
-h, --help show this help message and exit
-w LISTEN_ADDRESS, --web.listen-address LISTEN_ADDRESS
Address and port to expose metrics and web interface. Default: ":9840" To listen on all interfaces, omit the IP. ":<port>"` To listen on a specific IP: <address>:<port>
-i, --insecure Skip SSL validation of the printer website.
-c CONFIG, --config CONFIG
Configuration JSON file containing UPS addresses and login info.NOTE: make sure to provide an absolute path to ensure the file is found.
