Zdaemon uses a lot of resources

[jbeaumont]

Hi,

I'm running a Sentora installation on Amazon EC2 with Ubuntu 14.04. It hosts around 90 sites of various types; wordpress, concrete5 etc.

I've noticed the daemon fires every five minutes which seemed rather excessive. That was easy to change to every 15 via the cron entry in /etc/cron.d

But the main problem is the daemon uses a lot of disk IO every time it runs. Sometimes sitting the system at a 99% IO wait for seconds at a time. This goes on for a few minutes at a time before the daemon finishes its tasks.

I'm wondering if this can be tamed down a bit. What is it doing with the disk? If it's non essential stuff, are there any ways to disable certain parts of it from running?

Thanks.

Maybe by disable the webalizer module. This is a bit of a resource eater.

Hi bbspike. I should have mentioned I don't have the webalizer module running, as I found it was pretty resource hungry too.

I noticed from the logs it does this:

Code:

START Calculating disk Usage for all client accounts..

Given I have a lot of domains on this server could that take some time to do?

you can run daemon manually and see where it stops mostly.

use php /etc/zpanel/panel/bin/daemon.php

Best if you add log rotator here or clean up logs too.
