BIG-IP DNS: Check Status Of Multiple Monitors Against Pool Member

Good day, everyone!   Within the LTM platform, if a Pool is configured with "Min 1 of" with multiple monitors, you can check the status per monitor via tmsh show ltm monitor <name>, or you can clic...

Hi Cory,

 

Try this for your scenario:

 

tmsh show gtm pool a members detail | grep  -i -e "pool\|gtm\|reason"

or if need more details use this:

 

tmsh show gtm pool a all detail | grep -i -e 'gtm\|pool\|member\|availability\|state\|reason\|destination\|utime\|member\|vip'

 

You can modify it according to your requirement.

The output will be like this

tmsh show gtm pool a members detail | grep  -i -e "pool\|gtm\|reason"

Here are many more commands for other purpose i keep trying and experimenting, for that you have to be good in GREP :

 

The following command will find pools with a return to DNS option and print the name of the pools.

tmsh -c 'cd /; list gtm pool recursive all-properties one-line' | awk '/return-to-dns/{print $4}'

My Other GTM master Commands which i use frequently and keep customizing them based on the requirement

    Thank you for your response F5_Design_Engineer; I appreciate it!  Sadly, it seems the system is limited in it's response.

     

    The typical output of "tmsh show gtm pool a %MY_POOL% members detail" only shows a simple up/down status with a reason of one monitor.  What I'm looking for is to track the status of MULTIPLE independent monitors against a Pool member, when the monitor is configured as a "min 1 of" several monitors.

     

    The use case would be to be able to test a new monitor against a pool in parallel with what exists in production, all the while not impacting production with the test.  As I mentioned, the LTM platform allows you to do this by running a tmsh show against a specific monitor, but in gtm it appears this is not an option.

     

    I hope that helps to explain it better, and I really appreciate your assistance!
