syntax question

So let me start by saying I am new to TMSH and don't come from a scripting background.

I am writing a script that will create a custom monitor, a pool adding prepopulated nodes (every app has a pool with the same nodes in it) and the virtual host. I have something working that will do the first two steps but I want to make it prettier before I get to the third. I am a bit OCD and want the names to work.

So this is what I have (amazing what you can steal from the F5 articles and forums)

modify script /Common/josetest.tcl { <-----taken from the tmsh scripting page

proc script::init {} {

proc getFeedback { question } {

puts -nonewline $question

flush stdout

return [gets stdin]

}

}

proc script::run {} { <--------------put this next part all together from bits and pieces but it works

set app_name [getFeedback "what is the application name? "]

set tomcat [getFeedback "what is the tomcat port? "]

tmsh::create ltm monitor tcp $app_name defaults-from tcp interval 30 timeout 90 destination *:$tomcat

tmsh::create ltm pool $app_name {members add {172.20.36.110:80 172.20.36.111:80 172.20.36.112:80 172.20.36.113:80}} monitor $app_name

}

proc script::help {} {

}

proc script::tabc {} {

}

}

********SO my question is this...

I want the monitor name to be $app_name followed by "_" $tomcat

so it would look like this

what is the application name? TFA-joetest (Test Fast App-application name)

what is the tomcat port? 6789

then my monitor would endup in the monitor list as TFA-joetest_6789

Not sure of the syntax of adding the two values together I tried $app_name;-;$tomcat am I even in the right ballpark? (Sorry if this is a stupid question)

One more question, is there anyway to have my pool members in another location like a file or a class or data group list? This would be for a test application with 4 nodes, the prod apps have 25 nodes! 8^)

Thank you as always!!!
