Status oscillates w/check_by_ssh.

[Scott Zak]

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.

 Command line OK.






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?
