Dear Chad
Ø Have you recently upgraded Nagios?
Yes, I am running Core 3.2.3 since Feb 24th
Ø When did you start noticing that it was missing execution runs?
I noticed the problem month ago. even with version 3.2.1 - therefore I made an
upgrade to the latest version, to see, if this would fix the problem.
Ø Do you have enough disk space free?
As I said: 91 % free, only 9 % used
Ø What are the permissions of the script set to?
-rwxr-xr-x 1 nagios nagios 1035 Feb 18 10:17 rshsendsms
I said, it happens only sometimes. Wrong permissions would result in a never
working situation.
Ø Were they recently changed?
No.
Ø Have you done any type of software changes with any type of supporting
packages (i.e. Perl) that could have brought up this issue?
No, this server is running since Jun 2010 unchanged.
What happens within Nagios between writing the log-file and executing the
script ? Something permits to execute the script, but only sometimes.
Kind regards
Hans

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.

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 ?
Kind regards
Hans
