Slow page loads for users

Does nagiosxi resolve to an internal private IP address, or a external one?

Its a CNAME to the servers hostname which is on a external ip

What is the result of this command on your XI server:

Code: Select all

host nagiosxi

~]# host nagiosxi
nagiosxi.xxx.nz is an alias for rudolph.xxx.nz.
rudolph.xxx.nz has address 156.###.###.###

Can you go to Admin > System Config > Manage System Config

What is in your "Program URL" and "External URL" fields?

Mine was listed in Admin > System Config > System Settings (if that makes a difference)

Program URL is https://nagiosxi.xxx.nz/nagiosxi/
External URL is blank

So from what I understand what is happening, the ajax calls are going through a firewall to get to the public IP address of the XI server, and this is causing the delay. It's possible your firewall is limiting the amount of concurrent connections and hence slowing things down.

You could:
Define:
Program URL https://private_ip_address/nagiosxi/
External URL https://nagiosxi.xxx.nz/nagiosxi/

Then when accessing it internally, access it via https://private_ip_address/nagiosxi/

or

Setup split DNS so that nagiosxi.xxx.nz resolves to a private IP address when accessing it internally, so it doesn't need to go through the firewall.

This all assumes that your nagiosxi.xxx.nz server has a private IP address. If you only have a public IP address on the server then your options are limited, as all the traffic needs to pass through the firewall to get to the external address and back again.

Does this make sense or help?

It makes sense, and I should check the routing of traffic as it maybe going through the firewall and being restricted. However does that explain why the page loads fast for me, but slow for a different user. I would have thought firewall issues would have been relevant to all users, not a subset

Honestly I've banged my head trying to get to the bottom of these issues in the past. There may be a combination of two different issues going on here.

Let us know if my suggestion helps identify anything.

Ok, so I traced the statusjson.php file to try and find out if I could hammer in some debug to see where the slowdown was occurring...

statusjson.php makes use of a coreuiproxy.inc.php, which calls statusjson.cgi

I've captured the parameters that coreuiproxy.inc.php passes to statusjson.cgi and replayed this from the command line and it is performing well, which makes me think the sluggishness is coming from the php coreuiproxy file.

Unfortunately this means I can't step through to debug the fault any more ;/ As the coreuiproxy.inc.php is encrypted/obfuscated , but ill try watching the nagiosxi database queries to see if there are any locks or odd looking db queries coming through there..

Any other suggestions welcome, ill keep poking around

Haven't seen a ticket come through - did you try and get blocked or just haven't gotten around to it?

[ssax]

Locking the thread since a ticket has been created, we will continue it there.
