If you cat the pipe then the contents will be lost to nagios, as when items are read from the pipe they are automatically removed from it. Pipes have the first letter as a 'p' on 'ls -l'.

[Nagios-users] snmptraphandling.py
Is anyone using Francois Meehan's snmptraphandling.py script?
There's a part of the script where it opens the Nagios.cmd file. I'm not
a python coder, but it appears to me that it writes to the file with 'w'
which would overwrite any pending commands that Nagios has not yet
processed:
#print mondata_res
output = open('/opt/nagios/var/rw/nagios.cmd', 'w')
results = "[" + mytime + "] " + "PROCESS_SERVICE_CHECK_RESULT;"
\
+ host + ";" + "TRAP-" + service_suffix + ";" \
+ return_code + ";" + mondata_res + "\n"
output.write(results)
I'm thinking that this script should be opening the file with the 'a'
(Append) mode, so that unprocessed commands in nagios.cmd do not get
overwritten.
I do appear to be missing some traps within Nagios, I can see them as
far as snmptt, but it seems either sec.pl or snmptraphandling.py somehow
doesn't process them and the trap doesn't make it as far as Nagios.
