Hello all, I need some assistance with a script and hope someone here can be of help. We desired a script that would allow us acknowledgement from emails, who acknowledged and additional enhancements. I found a thread: http://article.gmane.org/gmane.network.nagios.user/49195 that provided a shell script to do exactly what we needed. However, the script was not formatted exactly to the Nagios stock emails of a default install so I modified it to the following the script to more suite what the default Nagios notifications look like:
#!/bin/sh
# Purpose: Modified shell script replacing stock Nagios notification to provide acknowledgement logic.
# Modified by dky at gmail.com
#Original script format: http://article.gmane.org/gmane.network.nagios.user/49195

The issue is that I cannot get the proper expansion of “$NAGIOS_SERVICEOUTPUT” variable. It seems to cut off here is an example:

Subject: ** PROBLEM Service ALERT: networkdevice.example.com/Check PING is CRITICAL **
***** Nagios *****
Notification Type: PROBLEM
Host: networkdevice.example.com
Address: 99.99.99.99
State: CRITICAL
Date/Time: Mon Jan 25 11:19:48 EST 2010
Additional Info: PING CRITICAL - Packet loss = 0
Acknowledge this alert: https://nagios.example.com/nagios/cgi-bin/cmd.cgi?cmd_typ=34&host=networkdevice.example.comNotice “Additonal Info: PING CRITICAL - Packet loss = 0”. With the stock Nagios config we get: “Additional Info: PING CRITICAL - Packet loss = 0%, RTA = 558.89 ms.” The script seems to be truncating the everything after the 0. I have tried to use the “NAGIOS_LONGSERVICEOUTPUT” variable but it returns no data at all! :shock: . I also tried enclosing the variable between double quotes ““NAGIOS_SERVICEOUPUT”” but still no luck. Can anyone chime in and tell me what I could be doing wrong to fully expand the variable?
Thank you for any input.
