Pool Member Status HTML5 Page

Cool. Can you upload the whole code for an XML solution?

Above my comment I had already posted it.

Hi Maneesh,, Does you code allow users to select/search particular pool??

For searching we would have to write a HTML page which calls XML using javascript for search capability.

I am asking a developer to assist me writing a HTML page for the same which will give search capability for finding pools. XML was taking long to load hence have coded a JSON i-rule which would be faster fetching results.

I would post the JSON code as well below this comment.

when HTTP_REQUEST { IP Block. Allow specific users/groups to access the status page. if { [IP::addr [IP::client_addr] equals 10.0.0.0/8 ] } { if { [HTTP::uri] eq "/json" } { set response "{ \"PoolDet\": ["

This is exactly what I have been looking for! But I am running into a little issue where pool members that are Offline still show as Up. The status of Disabled members show correctly. Any thoughts on what could be the issue?

Also, how hard would it be to add some additional information like hostname next to the IP:PORT and the description of the Pool next to the pool name?

Thanks in advance!

Jason,

 

Not sure why your Offline members are showing Up. I checked mine, and I have a couple members offline...one being due to a monitor setting it offline, and the other is due to manually disabling it. Both show Down on the HTML page. Maybe verify your settings/implementation is correct?

 

As far as adding the hostname... I looked into that while building the script and there was no easy/known way to incorporate the hostname from an iRule command, such as "[members -list $thispool]". The "members" command, for example, only pulls the IP and Port. Never tried looking at adding the description field.

 

With that said, you may be able to get those fields added using iCall, but I don't have enough experience with iCall, or time, to attempt it. If you or someone else wants to feel free. Can add that to the script if it works out.

LoyalSoldier,

Yeah its very bizarre as I have a couple pools that are Offline (Enabled) due to monitoring, but the status page still shows those Up. I wouldnt think it mattered if the node showed as Up under Nodes but the monitor has it marked down at the pool, correct?

Even more bizarre, I have a pool that is disabled and I have seen it change to up randomly.

Im supposed to use that actually name of the pool the pool, correct? The only reason I ask is in your screen shot above the pool names look like just random characters.

So I did a test on one of mine and caused a Pool to go Offline (Enabled). All the Nodes are still Available (Enabled). Looking at the Status Page, it now shows that Pool as having no available pool members and lists it in the top Critical box. This is how it should be working. The code is executed based on the pool members, not nodes.

On your disabled pool that randomly changes to Up....does it do that in the Configuration Manager as well? Show the member(s) being marked up in the logs? Would make sure it is operating as expected first outside of the Status Page.

Yes, you must add the actual pool names to the iRule Data Groups area. The screenshot contains gray boxes in areas that will change based on your setup (i.e. Pool Name, IP:Port, etc.). You do NOT put your Pool Names in those areas. The code will do that for you based on the iRule Data Group.

Great little script! Thank you for sharing this.
