Status oscillates w/check_by_ssh.

[Marc Powell]

You know that Nagios provides multi-view functionality right out of the box with just a single process and a single set of config files, right? If you're running multiple daemons just for different views then you've gone down the wrong path. With authentication enabled users are only able to see hosts and services that they are authorized contacts for.

We actually have four separate nagios daemons running to provided different views to persons who monitor groups of hosts and services.  They have parallel configurations in some aspects, but they shouldn't overlap.  Thanks for the tip.  I'll check it out.

After allowing the service checks to run for a while, I'm finding that the service status is oscillating between OK and UNKNOWN.  So it's working sometimes, and sometimes it's not.  Yikes. 

It doesn't seem likely that this has anything to do with timeouts or missed thresholds (I'm going to try increasing them anyway).

It's doing what it is supposed to do -- returning zero. 

That is also the return when running check_by_ssh on the nagios box.

Scott, 

When you run the command on the Sun box, what is the error code returned? 

Use the following command: 
> echo $? 

You should get a zero (0) if successful, or a one (1) or higher if not 
successful.

Hi , 

I'm setting up check_by_ssh to invoke a script via forced command on a 
remote server to check a service status.  The script returns the correct 
status on the server where it lives, and when I run check_by_ssh on the 
command-line, all is well.  Nagios runs the remote command (and displays 
the contents of stdout on the status detail page), but the status always 
comes back 'Unknown'. 

Command-line: 
[nagios at nagios1]$ libexec/check_by_ssh -H 149.152.10.183 -l remoteuser -i 
/path/to/rsa/identity_key  -C 'LDAP' 
LDAP daemon is running. 

When nagios runs the service check, the same 'LDAP daemon is running.' 
message appears in the status information, but the status is nevertheless 
marked as hard  'UNKNOWN'. 

Here's checkcommands.cfg: 

define command{ 
       command_name    check-cp-ldap 
       command_line    $USER1$/check_by_ssh -H $HOSTADDRESS$ -l remoteuser 
-i /path/to/rsa/identity_key -C 'LDAP' 
} 

This is the status log entry: 
[1104169159] 
SERVICE;soluminis1;LDAP;UNKNOWN;3/3;HARD;1104169025;1104169205;ACTIVE; 
1;1;1;1104157840;0;UNKNOWN;3706;335959;419;530;1104165074;2;1;0;1;1;0;0.00;0;1;1;1;LDAP 
daemon is running. 


Nagios is running on RH Linux, and the target host is Solaris 9.  Nagios' 
SSH is OpenSSH and the Solaris box is running Sun_SSH_1.0, protocol 
versions 1.5/2.0.  The remote script worked correctly when monitoring 
services on a Solaris 8 box which was running SSH Secure Shell 
(non-commercial license).  Check_by_ssh is from nagios-plugins 1.4.0alpha1, 
version 1.18. 

What am I not seeing?  It's probably some bonehead maneuver on my part, but 
has anyone else run into (and found their way around) this?
