The Prometheus Pushgateway exists to allow ephemeral and batch jobs to expose their metrics to Prometheus. Since these kinds of jobs may not exist long enough to be scraped, they can instead push their metrics to a Pushgateway. The Pushgateway then exposes these metrics to Prometheus.
Additionally to promethues pushgateway it address the issue prometheus/pushgateway#117
You can deploy the Pushgateway using the dmathai/prom-pushgateway-ttl Docker image.
For example:
docker pull dmathai/prom-pushgateway-ttl:latest
docker run -d -p 9091:9091 dmathai/prom-pushgateway-ttl:latest --metric.timetolive=60sIf we pass a argument metric.timetolive at the time of start up(Example : --metric.timetolive=60s),
the metrics will be removed from pushgateway after the 'metric.timetolive' from the time of pushing the metric.
The clean up jobs runs every 60 sec. So anything below 60 sec will not work.
