Hello,

First of all i want to say you thanks for your great idea to write such usefull plugins. But i faced with some problems when i began to use them. 

1. check_disk_remote  there was some strange problem with definition of current status by Nagios. On two servers Nagios showed current status UNKNOWN though Status information was OK and echo $? was 0.  On other servers all were ok. I removed next strings from plugin check_disk_remote:
# declare an error if we also get a non-zero return code from load
# unless already set to critical
#if ( $? ) {
#       print "stderr = $? : $! \n" if $verbose;
#       $state = $state == $ERRORS{"CRITICAL"} ? $ERRORS{"CRITICAL"} : $ERRORS{"UNKNOWN"}  ;
#       print "error: $!\n" if $verbose;
#}
And all became to work properly

2. check_load_remote. This script works fine except when the load on any server is four figures (f.e. 12.0,13.4,14.0)  At that time nagios shows like this:
 Current Status:
  OK    
Status Information:OK: load () is below threshold (12/15) Performance Data:load= 
Script can't count up the simple average of load values. I suspect that problem somewhere there:

my $avg = $2 if /load average: (\S{4}), (\S{4}), (\S{4})/i;

And there was the same problem with status which i solved the same way as in previous case.

Please could you advise me what should i do in order to change these scripts correctly?

Nagios' version is 2.0b4
plugins versions are:

 bash-3.00$ ./check_load_remote -V
check_load_remote (nagios-plugins 1.4.1) 1.0

bash-3.00$ ./check_disk_remote -V
check_disk_remote (nagios-plugins 1.4.1) 1.0

OS with Nagios - FC3
bash-3.00$ uname -a
Linux fly.pcb 2.6.12-1.1376_FC3 #1 Fri Aug 26 23:27:26 EDT 2005 i686 i686 i386 GNU/Linux

OS under test - Solaris 8 and 9

If you need more information i would be glad to grant it


Thank you for you attention.

With best regards,

Mikhail Danilov
