Thank you. For the MySQL Plugin to work, you need to create a user in MySQL.

This one is defined in a file called ip_compat.h. I'll try to get it
to work. So far, I've cloned the git repo to a Solaris host, and ran
build.sh. The ./configure script wasn't generated correctly, and
failed with unexpanded libnotify errors ‒ the libnotify macros are
absent on Solaris.

I made some progress. Installing CSWpkgconfig fixed the ./configure
problem. I have a patch for nfs.c, which I'll send shortly. I'm
currently facing a problem with conflicting defines in headers. Here's
the error message:

From what I see, the PACKAGE_BUGREPORT macro is defined by autotools.
The culprit is probably /usr/sfw/include/net-snmp/net-snmp-config.h
which shouldn't define the macro, but it does, and I can't change it.
At collectd, the macro is not used for anything, maybe it can be

Exec plugin - forked process freezing with 4.10.1 on Ubuntu 12.04 (precise)
Hello We've been using the Exec plugin to great effect on our collectd servers running on Ubuntu 10.04 (lucid) with collectd version 4.9.x but after upgrading to Ubuntu 12.04 (precise) and using the new version of collectd it ships with (4.10.1) the Exec plugin is now intermittently failing. What happens is similar to a thread from 2010 where the collectd process forks but then freezes up before exec'ing the external command specified in the Exec plugin definition. I have reproduced this on my laptop in a VirtualBox VM running precise and the same version of collectd. The details are here: https://gist.github.com/2878994 ... This feels like a collectd bug, but before I raise a bug report is there anything obvious anyone can think of here that I might have missed?

If I also deactivate the unixsock plugin then the problem goes away. So I think this is something to do with an interplay between the unixsock and exec plugins. Is anyone else using the exec and unixsock plugins with the collectd 4.10.1 as shipped with precise? Is it worth compiling 4.10.1 with debug symbols, reproducing, and attaching gdb to the frozen process? Jesse

Re: Exec plugin - forked process freezing with 4.10.1
Hi Jesse
We are using collectd 4.10.2 (close enough) with unixsock, exec and a host
of other plugins. We experienced similar problems and I spent a lot of time
debugging and getting it stable. I've posted my patches to the mailing
list, but will attach them here again. They should apply easily (touch
wood!) and there's a chance it will make things better. Here's the patches,
note not all are really relevant, I suggest you just apply the first 3 or 4:
Quick overview:
Fixed various collectd memory leaks.
Fixed collectd's unixsock read interrupted by SIGCHLD's.
Fixed collectd exec module: incorrectly exited select loop on signal.
Fixed incorrect collectd warning when configuring network plugin.
Collectd's scale plugin now supports scaling only on specific data
sources, yay! (New feature)
Apologies if I wasn't supposed to paste the patch in the body of the email,
but here goes:
commit ba04be9feeec4f40b9ada1cae64c0a27634f1c76
Author: Gerrie Roos <groos@...>
Date: Fri May 25 05:38:47 2012 +0200
Fixed various collectd memory leaks.
Once I understood what's going on I tried to keep the changes to a
minimum.

I've just compiled the vanilla 4.10.7 source and it exhibits the problem also. And similarly 5.1.0 exhibits the problem. I have seen the problem once on lucid 32bit with collectd 4.8.3. I've created a bug report for this here: https://github.com/collectd/collectd/issues/89 Jesse
