How to validate my JVM is running or not via bash script

[jeesshnasree]

Hi All,

In my machine Jboss EAP 7 product and three instances are up and running.

here 2 scenarios 

1) 3 JVM is up and running then how to validate via bash script 

2) if 1 JVM is up and running & remains 2 is not up and running, how to validate via bash script.

above mentioned both scenarios should execute one bash script for validation.

Example : 

JVM names :

JVM-Dev , JVM-QC  & JVM-UAT.

Please provide me above mentioned 3 JVM is up and running or not validate via bash script.

I hope , explained problem clearly.

I am waiting for your valuable information.

Regards,

You can use "pgrep -f java_app"  or "pgrep -x java_app" in your script to identify the java process ( https://man7.org/linux/man-pages/man1/pgrep.1.html ) and then use if - else statement in your script to echo the desired output based on number of JVM processes running.
