itrs-group / process-thread-monitoring

Monitors the threads of a specified linux or solaris process

Thread Level Process Monitoring

Introduction

This toolkit script utilizes packaged utilities ps and pgrep to query kernel information on the threads of selected processes. It creates a single dataview that lists the processes as you would see them in the processes view and utilizes the Geneos # syntax to group and indent the threads with their master process. This package currently contains solutions for linux and solaris.

Prerequisites

ps

pgrep: procps v3.0.0 or greater pgrep (http://procps.sourceforge.net/changelog.html )

sed

awk for linux

nawk for solaris

Usage

The arguments are a space separated list of strings to match against. If the search string has a space in it you need to double quote it. By default the rownames are the patterns supplied to the argument. If the pattern string is too complex for a rowname you can alias the rownames (e.g. pattern=alias). If there are multiple equals signs the alias is the string after the last equals sign.

threadstat_linux.sh ProcA ProcB "Proc C=C"

ProcA
	ProcA#1
	ProcA#2
ProcB
	ProcB#1
	ProcB#2
C
	C#1
	C#2

Notes

On solaris pgrep will only match against the first 80 characters of the command line.

If multiple PIDs match a single pattern then the oldest PID found is used.
