Pool Member status page iRule Version 11

you can do that natively in iRules with the members command and LB::status (example in the members wiki entry.) Of course if you want to dynamically discover new pools, would still need the script for that part.

Your script above is populating the class file properly on my test system:

"error_free_pool/192.168.101.10:80",
"lp1/192.168.101.20:514",
"lp2/192.168.101.21:514",
"lp3/192.168.101.22:514",
"testpool/192.168.101.10:80",
"testpool_alt/192.168.101.22:80",

Might look to the iRule to make sure the slicing and dicing of that data is working properly.

Jason thanks for looking at this. I am using the LB::status but I'm thinking there is a parsing difference with the way the b command and the tmsh command is presenting the data.

Below is the iRule snip referencing the LB:status.

    if { ([HTTP::uri] eq "/status") || (([HTTP::uri] starts_with "/status?") && ($query) && [info exists manualpool]) } {
            set timestamp "[clock format [clock seconds]]"
            set response "StatusPool NameMemberPort"

            set count 0
            foreach { selectedpool } [class get pool_member_status_list] {
                    set display 1             
                    if { [catch {
                            scan $selectedpool {%[^/]/%[^:]:%s} poolname addr port  
                            switch -glob [LB::status pool $poolname member $addr $port] {

looks like the scan is expecting the data string to be without the quotes:

% set x {"lp1/192.168.101.20:514",}
"lp1/192.168.101.20:514"
% scan $x {%[^/]/%[^:]:%s} poolname addr port
3
% puts $poolname
"lp1 **wrong!**
% puts $addr
192.168.101.20
% puts $port
514", **wrong!**

so you can either change the bash script to not echo the quotes (best) for each pool/ip/port, or string them off before passing to scan (see below), or update the scan command to account for them.

% set x {"lp1/192.168.101.20:514",}
"lp1/192.168.101.20:514",
% scan [string range $x 1 end-2] {%[^/]/%[^:]:%s} poolname addr port
3
% puts $poolname
lp1
% puts $addr
192.168.101.20
% puts $port
514

Jason I remove the quotes from the echo but I'm still getting INVALID status.

!/bin/bash

tmsh modify sys db bigpipe.displayservicenames value false

rm -f /var/class/pool_member_status_list.class

for POOLNAME in

tmsh list ltm pool | grep -i "ltm pool" | sort | awk '{print $3}'

for POOLMEMBER in

tmsh list ltm pool $POOLNAME | grep : | sort | awk '{print $1}'

  echo "$POOLNAME/$POOLMEMBER", >> /var/class/pool_member_status_list.class

oh, you're still using the services names instead of the port numbers. That tmsh command should do the trick, but looks like it is not.

Yeah I just tested that. Manually changed the class file to the ports and it worked. Any idea why the tmsh modify sys db bigpipe.displayservicenames value false wouldn't work?

what is the default value on your version? It's false on mine.

[root@ltm1:Active:Standalone] tmp  tmsh list sys db bigpipe.displayservicenames
sys db bigpipe.displayservicenames {
    value "false"
}

I'm running 10.2.4 in my test environment. Looks like this is a bug.

SOL13624

We are getting ready to upgrade to version 11 so it should work after that.

Thanks for all your help

no worries, check back if after the upgrade you need some help! BTW..wrt to upgrade from 10.x to 11.x, HA changes quite a bit, make sure you read up.

Finally getting around to upgrading to version 11.5.1 I'm testing out the pool status page. After figuring out the data group differences in v11 I've got it working. The only issue is the web page does not display the information alphabetically. The class file is populated alphabetically but the web page is random. Any idea why? I'm using the same irule as below:
