Validate Virtual Servers are LIve

Featured Replies

So we have a Develop F5 LTM and close to 2000 Virtual Servers.  Are they all active?  Probably not.  How do you tell?

My goal was to export all virtual servers

Partition,VirtualServer,VIP
Development,vip.ci.api-svc.thezah.com.https,172.47.32.160:7110

Next create a spreadsheet that CONCATES the netcat command and the IP address to validate the IP and port are open.  Something like

Command to use: nc -zv 172.47.32.160 7110 &> /dev/null; echo $?
Excel: =CONCATENATE("nc -zv ",[@VIP]," ",[@Port])

This will echo a 0 if its open and 1 if its closed.  (maybe I'll do some scripting and if 1 then echo whatever I am testing to a vserror.txt)

Again, this is just me throwing ideas to try.  I'll hope to have a working script eventually for you in this thread somewhere.  If anyone has ideas, please feel free to share.

Not sure about everybody's environment but I use a 301 redirect iRule that redirects port 80 traffic to its secure port (typically 443).  So I don't really want to test against they redirected Virtual Servers so I created a new list by running the following command

tmsh list ltm virtual /Development/* | egrep '301|^ltm|destination' | grep -v 301 > /var/tmp/vsdevNOTredirects.txt

This outputs just the live servers (without the 301 redirects)..  at least that was the plan but its not working.  I know there is a solution somewhere
