Have you recently upgraded Nagios? When did you start noticing that it was missing execution runs? Do you have enough disk space free? What are the permissions of the script set to? Were they recently changed? Have you done any type of software changes with any type of supporting packages (i.e. Perl) that could have brought up this issue? Here are some thoughts on where I would start looking. Anything that you can dig up we can look at more closely to identify a potential cause for this issue. ~Chad <div class="gmail_quote">On Wed, Mar 9, 2011 at 1:29 AM, MAYER Hans <<a href="mailto:mayer@iiasa.ac.at">mayer@iiasa.ac.at</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> <div link="blue" vlink="purple" lang="EN-US"> <div> <div> Dear all Using Nagios since a lot of years, I was starting with one of the first versions of “netsaint”, and more than 25 years of experience with UNIX, I have now a strange problem I never had before. I am running Nagios Core 3.2.3 on Solaris 10 OS. Hardware is M3000 with SPARC V9 architecture. My problem is, I see sometimes – not always – a service notification in the log, but it is not really done. Here an example, the entry in the log [03-09-2011 09:13:25] SERVICE NOTIFICATION: sms_mayer;amazon;DISK/p14amazon;OK;notify-service-by-sms;DISK OK - free space: /p14amazon 4531 MB (6% inode=99%): Here is the definition for notify-service-by-sms # 'notify-service-by-sms' command definition define command{ command_name notify-service-by-sms command_line $USER1$/rshsendsms $CONTACTPAGER$ \"Info: $HOSTALIAS$/$SERVICEDESC$ $SERVICEOUTPUT$ \" } As you see I execute a command named “rshsendsms”. And this are the first lines of the shell script: : # Wed Jan 19 10:12:15 MET 2011 - mayer initial # Wed Feb 16 10:11:54 MET 2011 - mayer logging the UID # usage: # rshsendsms 0043664xxxxxxx '"hello world - how are you "' # info: both types of apostrophes are important export PATH LOG NUMBER TEXT ID UID NOTSENT RUNLOG PATH=/usr/bin:$PATH LOG=/var/adm/rshsendsms.log RUNLOG=/var/adm/rshsendsms_run.log date '+%y%m%d %H:%M' >> $RUNLOG The first action I do, I write a log-entry. (91% of the disk is free) But in this case I cannot find the entry. The last one is dated with 110309 06:39, where I received a SMS really. I also switched on the process accounting weeks ago. But there is no entry to be found, that the shell script was executed. I also switched on the debug facility of “syslog”. I can find an equivalent entry like in the Nagios log. But there are no other messages, that something could be wrong. But on other hand I was informed at 06:39 and nothing was changed in the meantime. This is not the first time this problem happens. Most of the time notification works fine, but sometimes not. This is of course a pain as notification is one central functionality of Nagios. Any idea where I can start searching for the error ?
