BIGPIPE Command

Hi Nanda,

 

 

This is a good place for such a question.

 

 

Which LTM version are you running?

 

 

Are you mostly interested in finding virtual servers that have been manually disabled? Or do you want to find a VIP which is down because there are no pool members?

 

 

Are you wanting to check this regularly or detect when a VIP goes down?

 

 

Thanks,

 

Aaron

Hi,

 

 

Thank you for the response.

 

 

I am running LTM 9.1.1. I am interested in finding list of virtual servers which is down because there are no pool members or down because pool members are down. This is only one time task so that we can approach application owners to identify weather they still need that Virtual server.

If it's just a one time deal, you could piece this together in a few steps:

 

 

- Filter in the GUI's virtual server page for VIPs which are unavailable and save the list of VIP names to a text file on the LTM filesystem as /var/tmp/vip_names

 

- Run the following command:

 

 

grep -A 2 -f /var/tmp/vip_names /config/bigip.conf|egrep "(^virt|pool)"

 

 

If you want to get the pool membership list, you could grep for the pool name, save that to a file and then use:

 

 

grep -A 2 -f vip_names /config/bigip.conf| grep pool| awk '{print "b "$0" list"}'| bash

 

 

I'm sure there are more complete ways to handle this. But I don't think it's worth the time to develop a proper script if you only need to do it once.

Aaron, Can you please provide me more detailed instructions to perform this. I am not very good at linux / unix. I actually saved the list of VIP names as .txt on my system and copied it back to LTM (/var/tmp/vip_names). When I run the command - grep -A 2 -f /var/tmp/vip_names /config/bigip.conf|egrep "(^virt|pool)" - it dose not give me any out put.

Can you run:

 

 

grep -A 2 -f /var/tmp/vip_names /config/bigip.conf

 

 

and see if it returns anything? If so, can you post the anonymized output? If not, either the file isn't readable or it doesn't contain the virtual server names.

 

 

Thanks,

 

Aaron

Aaron, Here is the output. It still dose not show me any thing.

 

 

[root@int-f5-mgmt-alpha:Standby] vip_names pwd

 

/var/tmp/vip_names

 

[root@int-f5-mgmt-alpha:Standby] vip_names grep -A 2 -f /var/tmp/vip_names /config/bigip.conf

 

[root@int-f5-mgmt-alpha:Standby] vip_names

 

 

The content of vip_names.txt file is as below.

It looks like you created a directory and then a file named vip_names. If that's the case, can you change the grep command to:

 

 

grep -A 2 -f /var/tmp/vip_names/vip_names /config/bigip.conf

 

 

If that works, then try:

 

 

grep -A 2 -f /var/tmp/vip_names/vip_names /config/bigip.conf|egrep "(^virt|pool)"

 

 

Thanks,
