Original msg: > Warning: Passive check result was received for service '0' on host > 'server1', but the service could not be found!
NSCA daemon makes the host/service check determination based simply on the number of arguments. If you take a remote nagios instance which is reporting passive host/service checks, you can bump the debugging_level=384 and see something like this: [1196258852.155446] [256.1] [pid=20619] Running command '/usr/local/libexec/nagios/send_host_check fbsd05 0 'PING OK - Packet loss = 0%, RTA = 0.67 ms''... In this case, there are the proper number of arguments: 3 But NSCA recieving this msg is seeing 4 arguments. A closer look at /usr/local/libexec/nagios/send_host_check reveals why: #!/bin/sh /bin/echo "$1","$2","$3" | /usr/local/sbin/send_nsca -H master.tld \ -c /usr/local/etc/nagios/send_nsca.cfg -d "," This means that depending on how shit is escaped within: - Nagios on remote node - /bin/sh - send_nsca binary Therefore, a $3 value of: 'PING OK - Packet loss = 0%, RTA = 0.67 ms' May or may not be truncated into three values. I'm going to track it down further. ~BAS ---------- Forwarded message ---------- Date: Mon, 19 Nov 2007 13:52:21 -0500 (EST) From: Brian A.
