process_exporter

Makes available the following metrics for Prometheus for processes matching a given name:

• CPU usage
• RAM usage
• Swap usage
• Disk IO (bytes)
• Disk IO (count)

Requirements

• Go 1.13

Building

./build.sh

Usage

./process_exporter -namespace # Prometheus metric namespace (default: "my")
                   -binary # Name of binary to monitor
                   -nameflag # Infer value of "name"-label from value of this command line flag of monitored process (default: "name")
                   -port # Port to listen on for request (default: 80)
                   -interval # Interval between metrics being refreshed, in seconds (default: 10)

Metrics

Example output from curl localhost/metrics for process_exporter -binary top -nameflag d for top -d 1. (Exploiting top's -d parameter as a unique identifier)
