Some pool members show up as invalid: https://devcentral.f5.com/wiki/iRules.Pool__Member__Status__Page_on_a__Virtual__Server_v10.ashx

I just found that in the pool_member_status_list.class file, these two sites ports were not listed for some reason. As i udnerstand the cron job creates this. I updated the list manually, and we will see what the cron job does to it next time it runs. The ports for these sites are 60090 and 60100, so the common theme here is that they have zeros at the end of their port. I will keep you posted.

I would edit the iRule to make it print details in the INVALID case, log something like:

 

 

"Pool: $poolname Member: $addr:$port] Status: [LB::status pool $poolname member $addr $port]"

 

 

What i tried did not work, it just replaced the nodes again with no port which obviously is invalid.

 

 

Where in the irule to place that statement?

 

 

Thanks.

The cron job populates the .class file. For some reason for pool members with ports of 60100 and 60090 do not have their ports defined in the .class list. Is there something in the .cron job that is causing this?

Yes, there's a bug of some kind in the script which generates the data group file. I'll take a look today and see if I can find the issue.

That would be great!! Let me know if you need anything from me.

Can you try this updated version of the script? If it works for you too I'll update the Codeshare example.

!/bin/bash

 Handle a first-run situation
if [ ! -e /var/class/pool_member_status_list.class ]; then
    touch /var/class/pool_member_status_list.class
fi

 Grab the node list from bigpipe
nodelist=`b pool all |grep "POOL MEMBER" | awk '{sub(":any",":0",$4);print "\""$4"\","}' | sort`
for i in $nodelist; do
     Get the service from the bigpipe output for the pool member
    service=`echo $i | cut -f2 -d : - | sed s/\",// -`
     Determine whether the service is a numeric value or not; if not, we'll look it up in /etc/services.
    if [[ $service =~ ^[0-9]+$ ]] && (( 0 <= $service && $service < 65536 )); then
        servicenumber=$service
    else
        servicenumber=`cat /etc/services | tr '\011' ',' | sed s/,,/,/ | grep "^$service,.*\/tcp" | cut -f2 -d, | cut -f1 -d/`
    fi

     Write it to a temp file in the class directory.
    echo $i | sed s/$service\"\,/$servicenumber\"\,/ >> /var/class/pool_member_status_list.class.tmp.$$
done

 Move the temp file to the active position.
mv /var/class/pool_member_status_list.class.tmp.$$ /var/class/pool_member_status_list.class

 Only load the config to update with the new class file if I am in HA Active mode (avoids getting out of sync if
 this happens on the Standby unit).
if [ "`cat /var/prompt/ps1`" == "Active" ]; then
    b load
fi

exit 0

Thanks, Aaron

Aaron,

 

 

Thank you. I have the script in place, but since it is set to be a daily job, is there a way to run it manually? I am looking for documentation on how to manually run a cron job but have not found it yet.

 

 

Thanks.

From BIGIP shell prompt:

 

 

/etc/cron.daily/pool_member_status_list.cron

 

 

Ha, i was going to try that but was not sure, thanks that worked.

 

 

Aaron, it seems to work perfectly now. Thank you so much. What did you have to do?
