Bug #33141
Disable broken collectd ipmi plugin
Description
The ipmi shared library is shipped in /usr/local/lib/collectd and depends on the OpenIPMI shared library in /usr/local/lib however when collectd runs, it fails because it cannot see the ipmi.so. This is because LD_LIBRARY_PATH is not initialised. Another way to fix this is to populate /etc/ld.so.conf properly.

This may not be a ld.so.conf problem but the error is:
/usr/local/lib/collectd/ipmi.so: Undefined symbol "ipmi_smi_setup_con"
This is because OpenIPMI is built without support for ipmi_smi. The configure options in OpenIPMI disable it by default but it more or less works as it is if you use <sys/ipmi.h> from FreeBSD.
See the attached patch for additional details.
However it would seem that this is not enough to get ipmi from the local system :(
truss shows this:

workaround - use a python plugin to invoke ipmitool
import collectd
import string
import subprocess
from subprocess import Popen, PIPE
def read_func():
lines = []
p = Popen(['/usr/local/bin/ipmitool', 'sensor'], stdout=PIPE, stderr=PIPE, shell=False)
data = p.communicate(input='')[0]
lines = data.splitlines()
if len(lines) > 0:
for line in lines:
F = line.split('|')
type = None
ftwo = F[2].lower()
if 'rpm' in ftwo:
typename = 'fanspeed'
elif 'degre' in ftwo:
typename = 'temperature'
elif 'volt' in ftwo:
typename = 'voltage'
else:
continue
value = F[1].lstrip()
value = value.strip()
if value == 'na':
continue
name = F[0].lstrip()
name = name.strip()
val = collectd.Values(type = typename, type_instance = name)
val.plugin = 'ipmi'
val.dispatch(values=[value])
collectd.register_read(read_func)

I've just retried it with latest ports and it is still broken. I've decided just to disable it for now. May be collectd update one day help it.
