Subject: FW: Nagios: Error while writing to pipe
Hi All,
I am new to Nagios, I am trying to receive SNMP Trap from
Windows client machine. I am using Python script to see how Nagios can
create an event/alert
by checking Passive Service Check Result submitted by this script.
I have attached the Python script which is used write "Passive
Service check Result" to Nagios external command file
for creating an alert/event. But when I run this script
--------------------------------------------------
[EMAIL PROTECTED] eventhandlers]# pwd
/usr/local/nagios/libexec/eventhandlers
[EMAIL PROTECTED] eventhandlers]# python snmptraphandling.py 10.207.40.203
CRITICAL 12
2
[EMAIL PROTECTED] eventhandlers]#
---------------------------------------------
I get following error:
[EMAIL PROTECTED] rw]# tail -f nagios.cmd
[1190731734]
PROCESS_SERVICE_CHECK_RESULT;10.207.40.203;snmp_trap_handling_critical;2
;" 12"
tail: nagios.cmd: file truncated
tail: nagios.cmd: cannot seek to offset 0: Illegal seek
[EMAIL PROTECTED] rw]#
--------------------------------------------------
nagios.cmd is a pipe:
[EMAIL PROTECTED] rw]# ls -l
total 0
prw-rw---- 1 nagios nagcmd 0 Sep 25 20:18 nagios.cmd
[EMAIL PROTECTED] rw]#
[EMAIL PROTECTED] rw]# pwd
/usr/local/nagios/var/rw
why I am getting Illegal seek error. I have tried to use this script to
a normal read write file and it works fine, but while writing to a pipe
it is
showing error. If the problem is due to the script then it could be here
output = open('/usr/local/nagios/var/rw/nagios.cmd', 'w')
print return_code
results = "[" + mytime + "] " + "PROCESS_SERVICE_CHECK_RESULT;"
\
+ host + ";" + "snmp_trap_handling_" + service_suffix + ";" \
+ return_code + ";" + mondata_res + "\n"
output.write(results)
It could be file(pipe) permission problem, I have no idea.
I have followed below link to give permission to nagios.cmd
http://nagios.sourceforge.net/docs/2_0/commandfile.html
Thanks & Regards,
Pankaj
