Typical usage:
io::prometheus::NewGauge name=start_time help='When the run began'
start_time set "$(date %s)"
io::prometheus::PushAdd job=cronjob instance='' gateway=:9091
: main cron job code goes here
io::prometheus::NewGauge name=end_time help='When the run ended'
end_time set "$(date %s)"
io::prometheus::PushAdd job=cronjob instance='' gateway=:9091
This is a library to help you push metrics from your Bash script to a Prometheus pushgateway server.
It's written to use GNU Bash's features,
mainly because the basic POSIX shell doesn't support the local keyword.
The library is still missing some essential features such as documentation and non-gauge metrics.
