I have 5 hosts and each host as 3 java process .I have one machine which has ssh keys so it can login without any passwords etc to all the machines.
How can I find out say jstack or some command so it goes to each machine and run the command . For example machine 1 has 3 java process and they all have different process ids . I want to run " jstack <pid> " on all machines .
I tried something like
for i in 1 2 3 ; do echo "running jstack"; ssh -q host1 pgrep java ; echo ""; done
I can get the process for each machine but not sure how to run "jstack pid> based on pid
thanks in advance
