hi,
In order to Minimize CPU time and CPU % taken by jvmtop.sh to find and display
all the JVM found, can we have an argument like
./jvmtop.sh --once <jvm name>
eg:
./jvmtop.sh --once org.jboss.Main
OUTPUT:-
JvmTop 0.7.1 alpha - 06:13:38, amd64, 4 cpus, Linux 2.6.18-19, load avg 0.00
http://code.google.com/p/jvmtop
PID MAIN-CLASS HPCUR HPMAX NHCUR NHMAX CPU GC VM USERNAME #T DL
11228 org.jboss.Main 549m 3993m 70m 304m 0.00% 0.00% S6U25 compiere 74
This would limit what jvmtop search and query for. making less CPU usage and
intensive.

On Unix, you can use awk to apply such kind of filtering:
./jvmtop.sh --once | awk '$1 == "JvmTop" || $1 == "PID" || $2 == "org.jboss.Main"'
(the first two || arguments are there so that the header and column lines are displayed ⇒ remove them if such behavior is not desired)
Notice that this works even without the --once option but then filter on "JvmTop" on 2nd column for dynamic refresh:
./jvmtop.sh | awk '$2 == "JvmTop" || $1 == "PID" || $2 == "org.jboss.Main"'
