prometheus-process-exporter1

Usage

Overview

Some apps are impractical to instrument directly, either because you don't control the code or they're written in a language that isn't easy to instrument with Prometheus. This exporter solves that issue by mining process metrics from procfs.

The recommended option is to use a config file, but for convenience and backwards compatibility the -procnames / -namemapping options exist as an alternative.

The -children option (default:true) makes it so that any process that otherwise isn't part of its own group becomes part of the first group found (if any) when walking the process tree upwards. In other words, resource usage of subprocesses is added to their parent's usage unless the subprocess identifies as a different group name.
