The top_process gadget periodically reports process statistics, including CPU usage, memory usage, and other process information.

Getting started​

Running the gadget:

$ kubectl gadget run ghcr.io/inspektor-gadget/gadget/top_process:v0.41.0

Guide​

The top_process gadget provides detailed information about running processes, including:

  • Process ID (PID)
  • Parent Process ID (PPID)
  • Command name
  • CPU usage percentage
  • Memory usage (RSS and virtual)
  • Thread count
  • Process state
  • User ID

It also adds environment enrichments (container/k8s information), if possible.

You can sort the output by any field, for example by CPU usage:

$ kubectl gadget run ghcr.io/inspektor-gadget/gadget/top_process:v0.41.0 --sort -cpuUsage --max-entries 12
