Resource usage not updating

Submitted by fatbox on Tue, 09/08/2009 - 12:32

Hi Jamie,

I just noticed this morning that sometime after Cloudmin 2.9 (might have been 3.0, but I didn't check and now I'm on 3.1) all of the Resource Usage collection has stopped.

When I goto Cloudmin Settings -> System Statistics Graphs it shows absolutely nothing and when I go in to edit a virtual machine and look in Resource usage it shows an uptime of 0 even though the machine is up and running.

Accounting period Current month
System uptime over period 00 minutes, 00 seconds (0% of period)

Here's the crontab for root from my cloudmin system

49 23 * * * /etc/webmin/cron/tempdelete.pl
0,5,10,15,20,25,30,35,40,45,50,55 * * * * /etc/webmin/server-manager/status.pl
39 * * * * /etc/webmin/server-manager/licence.pl
2,7,12,17,22,27,32,37,42,47,52,57 * * * * /etc/webmin/server-manager/bandwidth.pl
8 10 * * * /etc/webmin/server-manager/space.pl

Let me know what else I can provide you to track this down.

Thanks!

Looks like it is still working OK on my test systems ..

If you run /etc/webmin/server-manager/status.pl as root at the shell, does it output any errors?

Also, how long does it take?

Finally, do the statistics graphs show anything for any system, such as the non-virtual ones?

Well, well, well...

(#169:1u:0r:0s) root@yyz1-cloud[/U/evan]: /etc/webmin/server-manager/status.pl
bash: /etc/webmin/server-manager/status.pl: No such file or directory

I guess that explains it. I guess that also means that I'm not getting root mail from my cloudmin system...

I fixed up the root mail issue and sure enough every 5 mins I get Cron output about collectinfo.pl & status.pl.

Here's the output of my /etc/webmin/server-manager directory:

When I initially installed Cloudmin there wasn't an install script for Debian/Ubuntu so I did it by hand (and it installed into /usr/local/webmin). Thinking that using the new script might help I decided to backup my /etc/webmin directory and go through the install script.

The script bombed out at this point:

E: Sub-process /usr/bin/dpkg returned an error code (1)

I blew away /usr/share/webmin/{server-manager,virtual-server-mobile,security-updates} and re-ran the install script. It completed without any errors and my Cloudmin is still usable via the http interface but the status.pl & collectinfo.pl scripts still do not exist in /etc/webmin/server-manager.

Next steps?

It looks like those scripts aren't being created as Cloudmin's installer is still seeing the cron jobs.

The fix is to remove the cron jobs for status.pl and collectinfo.pl , then run :

cd /usr/share/webmin
export WEBMIN_CONFIG=/etc/webmin
export WEBMIN_VAR=/var/webmin
/usr/share/webmin/postinstall.pl server-manager

You don't need the collectinfo.pl script, as that is part of Virtualmin and not Cloudmin.

I don't seem to have a postinstall.pl in /usr/share/webmin...

Sorry, the commands should be :

cd /usr/share/webmin
export WEBMIN_CONFIG=/etc/webmin
export WEBMIN_VAR=/var/webmin
/usr/share/webmin/run-postinstalls.pl server-manager

However, since you sent me the new Cloudmin with the new bridge support (which is great, btw) I removed the cron entries and then ran dpkg -i on the new .deb file again.

The cron entries are back and the status.pl script exists again.

Yes, that would work too ..
