* Try to restart sw-collectd if you didn't restart it.

* Try to decrease "Interval" parameter in file "/etc/sw-collectd/collectd.conf".
Now it's 300. It means that every 300 seconds daemon collect values and put it to files.
You can set 100 or 200, for example. One time we had the same problem with interval.
Warning: If you set too little value, resource usage of server will be greatly increased.
 
i already did a restart.

interval is set to 100. i checked the status after approx. 5 minutes and saw some values for memory, disk usage and processes but not for apache, mysql, interfaces. now after 40 minutes all values are "0" again!

very interesting...
 
Try to make sw-collectd logging:

vi /etc/sw-collectd/collectd.conf

Add following after "LoadPlugin interface":

LoadPlugin logfile
<Plugin logfile>
LogLevel "debug"
File "/var/log/sw-collectd.log"
Timestamp true
</Plugin>

You can set LogLevel "debug" or "info".

Restart sw-collectd:
/etc/init.d/sw-collectd restart
Look at log file after 5-10 minutes passed:
less /var/log/sw-collectd.log

Maybe you will see some errors in log-file.
 
Having the same problem, with the health monitoring.
I enabled the logging and after 10 minutes this is all there is.

I guess thats a race condition. There is a small time window between checking the processlist and checking the entries in /proc/≤pid>

During this time the process with the PID 28712,28713 etc gets terminated. I think it shouldn't be anything to worry about ...
 
To everyone with a problem: take a look at http://forum.parallels.com/showthread.php?p=629338, section 3 (sw-collectd data collection interval is too low) and execute the proposed solution (even if you already have a large enough sw-collectd interval value). Note that it has important 3rd step.

Please report whether it helped you or not.

Regarding the "Failed to open `/proc/28712/cmdline': No such file or directory." errors. abdi is quite right. It is a harmless race condition in the collectd.
 
Mine is also down and none of the above has worked

I am on a CentOS 6.2 final with plesk 11 which just updated again on the 8th. Prior to the 8th the Health monitor was working fine and now, nothing. Everything is zeros. I did the restart and it says it restarted fine but that made no change in the monitor report.

Any other ideas plesk folks? I use the monitor quite a bit when working with mysql .....
