By running top, htop, uptime, etc. we can see the load average as three values indicating the average load for the last 1/5/15 minutes (well not really, but that isn't the question here).
Sometimes I'll notice that I have a fairly high load average for the last 15 minutes, but the current load is very low.

A few minutes ago I signed up at a new webhost. I have yet to move my sites over.
I have a problem with a high traffic wordpress, super high CPU load under nginx php-fpm, I am caching with apc, and memcached, spent 2-3 days tweaking configs and looking for answers it seems to me that php-fpm takes up all the cpu available no matter how many max_children i set if i set 5 then the load is 20% each, if i set 20 then the load adds up till 90% i tried static and dynamic
server is 2
I need to debug sudden load peaks automatically. We already monitor with nagios like check scripts, but the load peaks are seldom and short.
I search for a daemon which checks the load every N seconds and if there is trouble, reports something like ps aux --forest (and iotop --batch)
Graphs created with e.g. munin don't help here, since I need to identify the processes which cause the load.
on running the uptime command, it tells me that I have 5 users logged in. I don't understand this since I have on one user registered on this computer. This is the output
11:07:19 up 5 days, 1:11, 5 users, load average: 0.42, 0.67, 0.56
I had the query as to whether the load average in a multi CPU machine should be
(load average/no of CPUs)
We have 4 CPU on our VMware RHEL instance, so the load average should be
Load average/4.
I hope, my question is clear.
Please revert with the reply to my query.

A Drupal 7 site with CiviCRM, after running smoothly for a year on a 1&1 VPS suddenly became unresponsive. Now pages eventually load, but can take more than a minute.
Looking at resource use in Virtuozzo, the load average carries a warning, and has remained above 1. While I understand this isn't particularly high, this is a change from when the site was working.
I have a server that's running CentOS 5, and it will periodically (a couple of times a day) have enormous spikes in load, and the whole server will grind to a halt.
