Script to identify if unit is active or standby

My goal is to enhance our current deploy script. When we deploy new code to our tomcat/jboss instances our script will invoke some java code to disable a member from the pool, deploy the code and bounce then enable the member again. Rinse and repeat. Our F5 host value is hardcoded in the shell script and I would like to make the script include a check to see if the primary is currently the active F5.

 

 

I was hoping there would be a way to just include a wget or something without having to go further and use the API.
