Hello.
I was working on making nagiosgraph/rrdtool work with my Nagios 2.0
installation when I came upon this issue.
I have the following in nagios.cfg:
process_performance_data=1
service_perfdata_file=/var/spool/nagios/perfdata.log
service_perfdata_file_template=[SERVICEPERFDATA]\t$TIME$\t$HOSTNAME$\t$SERVICEDESC$\t$SERVICEEXECUTIONTIME$\t$SERVICELATENCY$\t$SERVICEOUTPUT$\t$SERVICEPERFDATA$
service_perfdata_file_processing_command=process-service-perfdata
In checkcommands.cfg I initially tried the default of:
define command {
command_name process-service-perfdata
command_line /usr/bin/printf "%b"
"$LASTSERVICECHECK$\t$HOSTNAME$\t$SERVICEDESC$\t$SERVICESTATE$\t$SERVICEATTEMPT$\t$SERVICESTATETYPE$\t$SERVICEEXECUTIONTIME$\t$SERVICELATENCY$\t$SERVICEOUTPUT$\t$SERVICEPERFDATA$\n"
>> /usr/local/nagios/var/service-perfdata.out
}
I found that I saw output that I expected in
/var/spool/nagios/perfdata.log (i.e. real hostname, servicename, stuff,
etc), but the target file of the process-service-perfdata command
yielded nothing but emtpy lines.
I tried replacing the printf with simple echo's of individual macros and
got nothing. I changed the command line to a shell script that did
nothing but echo it's shell environment to a file and any arguments
passed on the command line. The shell environment showed up in the file
but the only things that showed up from the shell script's command line
were non-macros. For example, I had
command_line /usr/local/nagios/etc/M.sh FOO $HOSTNAME$
and I'd see "FOO" in the output file. The shell script had an "env >>
/tmp/output" line in it so I could see the shell environment. There
were lots of nagios env variables there, but most were empty including
things like $NAGIOS_SERVICEDESC.
Clearly the macros are being expanded elsewhere (host/service checking
commands, and writing directly to the perfdata file), but I can't get
them to be available at all with my perfdata processing command.
What am I doing wrong?
I've recently fired up Nagios 2.1 and run with the same configuration
and it made no difference.
Thanks
Mark
