[Cases 47292, 47314] Sweet Munin Update!

[fkatzenb]

Nice push... thanks!

[fkatzenb]

Can anyone remind what the fix is to keep exim from zipping the logs so munin continues to work with exim? Thanks!

[cPanelTristan]

Hello,

It is likely that you have /etc/logrotate.conf set to compress for this section of it:

# uncomment this if you want your log files compressed
compress

If that isn't set to allow compression, then I'm not certain how only exim is being compressed unless you've defined a special one for exim itself. cPanel itself doesn't define the exim logs rotation, since WHM > cPanel Log Rotation Configuration area doesn't have exim listed.

Thanks.

[fkatzenb]

Thanks! I remember now. This is a new server and I forgot what I did to make it work.

Saw the update on some servers and not on others.

Anyone have the command handy for forcing the munin update from the command line?

[cPanelTristan]

Do you have the following selected in WHM > Manage Plugins for Munin?

Install and keep updated

If you do and it isn't the newest, simply try saving the area. If that doesn't work, you might try a forced cPanel update:

/scripts/upcp --force

We're having some trouble getting the exim mail stats to work following the update. It always used to work but now the graph is blank.

Calling it via munin-run outputs letters rather than a numerical value

# munin-run exim_mailstats
received.value JC
completed.value JD
rejected.value BMK

and calling the module directly outputs what looks like perl errors

Have tried reinstalling Munin from WHM but no luck. Any ideas?

Hello,

Would you be able to follow the steps in this discussion and let us know the results?

View topic - Problem with exim_mailstats on FreeBSD :: For Linux & Unix Server Administrators and Developers :: BlueQuartz.US

It has the same error when trying to run the command in root:

Empty compile time value given to use lib at /usr/share/munin/plugins/exim_mailstats line 74

Next, it also mentions erroneous data being produced. As a question, what operating system are you using? Does it happen to be FreeBSD or is it CentOS?

Thanks.

I have followed the thread and tried the debugging lines that are mentioned, the log file position seems to increase but the data values are strange (letters rather than numbers)

2011/02/18-01:10:03 [20215]     Pre: Exim log file position is 14639800, number of rejects is BO
2011/02/18-01:10:03 [20215]     Post: Exim log file position is 14644693, number of rejects is BS

2011/02/18-01:15:03 [21725]     Pre: Exim log file position is 14644693, number of rejects is BS
2011/02/18-01:15:03 [21725]     Post: Exim log file position is 14650417, number of rejects is CC

I've also tried removing the "use lib" line in /usr/share/munin/plugins/exim_mailstats but that doesn't seem to have made any difference.

The OS is CentOS, actually this is happening on 2 different CentOS machines; one 32 bit and one 64 bit. The exim graphs on both machines were working fine up until the munin update last night.

Hello,

Would you be able to open up a ticket using WHM > Support Center > Contact cPanel or via the link in my signature for us to look into this further? The prior errors provided aren't common errors at all. I tried searching the desk for them and online and the link I provided in my last response was the only place that had any part of the error you were receiving.

Once you've opened up a ticket, if you could post the ticket number here.

Thanks!

[LDHosting]

I think I may have found the solution. I just found the following ticket and made the changes that are mentioned in it. Munin now seems to be generating the exim throughput graphs again and running "munin-run exim_mailstats" returns a numeric value as expected.

#985 (exim_mailstats plugin does weird string arithmetic after initializing) - Munin - Trac

Maybe this can be changed for a future update? Hopefully this will help anyone else that might be experiencing this anyway.

Thanks for the help, Tristan!

It turns out my problem was the same as his!

root@one [/]# cat /etc/logrotate.conf
# see "man logrotate" for details
# rotate log files weekly
weekly

# keep 4 weeks worth of backlogs
rotate 4

# create new (empty) log files after rotating old ones
create

# uncomment this if you want your log files compressed
# compress

# RPM packages drop log rotation information into this directory
include /etc/logrotate.d

# no packages own wtmp -- we'll rotate them here
/var/log/wtmp {
    monthly
    minsize 1M
    create 0664 root utmp

}

# system-specific logs may be also be configured here.
root@one [/]# munin-run exim_mailstats

Hello,

after the munin update in last day, the "Exim Mail Throughput" stopped work.

Not only in one server, but in all my servers. This graph is very important for me to control spam and mail usage.




Can you help me, please?

thank you
Arvy

I had exactly the same problem, but managed to find a solution from a Munin bug report which I posted here

http://forums.cpanel.net/f5/sweet-mu...tml#post789311

If you have root SSH access, the steps that I took were:

Backup the existing file (just in case)

cp /usr/share/munin/plugins/exim_mailstats /usr/share/munin/plugins/exim_mailstats.bak

Edit the file with your favourite editor (vi, nano, pico etc)

vi /usr/share/munin/plugins/exim_mailstats

Change line 109 from

if ($rotated) {

TO

if ($rotated || $received eq 'U') {

and save the file

remove the existing state file

 rm /var/lib/munin/plugin-state/exim_mailstats-127.0.0.1

Restart Munin

/etc/init.d/munin-node restart

After 10 minutes or so, you should see the points plotted on the throughput graph again.

Hopefully cPanel will have a more elegant solution soon, but this did the job for me.
