kurtcebe / svmon_servers.sh

Last active October 31, 2018 14:11

Scripts to determine memory usage in AIX boxes. I use there for monitoring Application Server processes (Java), to get a better idea about how much of the resources are utilized by servers. svmon, used like this, does not take into account memory used as file system buffer, so gives a better idea compared to topas.

	# memory usage for all active processes
	svmon -P

	# same as above, one line for each process
	svmon -P -O summary=basic,unit=MB

	# Total memory used and total number of processes
	svmon -P -O summary=basic,unit=KB \| tail +4 \| awk '// {total+=$3} END {print "total mem=",total/1024/1024," GB, n=",NR}'

	# Total memory used and total number of processes for Java processes only

kurtcebe / jarForClass.sh

Last active December 19, 2015 23:59

Script to find which jar file contains a given class, searching through jar files in a directory hierarchy.

	#!/bin/bash
	for i in `find . -name '*.jar'`; do jar -tf "$i" \| grep $1 \| xargs -I{} echo "$i : {}" ; done

	# if 'jar' is not in the path, you may use 'unzip -l' instead of 'jar -tf'
