USER macro not being interpreted.

[yo_marc]

Hi all, I am experiencing a weird issue with my 5.2.7 XI instance.

I am trying to define some custom $USERn$ macros in resource.cfg.

They are defined like this:

$USER10$=testaccount
$USER11$=testpassword

I am trying to use those $USERn$ macros in a Service check in the CCM - I am passing them through the $ARG1$ and $ARG2$ options. The dollar-signs are being escaped, and the variable not interpreted when I run "Test Check Command"

A screen shot of the config is attached.

Output from "Test Check Command" is as follows:

COMMAND: /usr/local/nagios/libexec/check_mssql_server.py -H testhost.testdomain.com -U \$USER10\$ -P \$USER11\$

OUTPUT: (18456, "Login failed for user '$USER10$'.DB-Lib error message 20018, severity 14:\nGeneral SQL Server error: Check messages from the SQL Server\nDB-Lib error message 20002, severity 9:\nAdaptive Server connection failed (testhost.testdomain:1433)\n")

This doesn't seem to be the way things should work. Is there a place I can start looking to figure out why this is happening?


Additional info:

The $USER1$ variable is correctly passed as an ARG - even when passed through $ARGn$ in the CCM.

There are no strange characters used in the resource.cfg. There are no other USER macros defined, other than the XI defaults (USER1, USER7 and USER8, and the two mentioned here). $USER1$ is the only one that gets interpreted.

I have another 5.3.3 XI instance, and everything works great there. I understand there were a number of changes along the way, but I dont see any bugfixes regarding this in the XI 5 release notes... so I am not confident this is a bug; rather some sort of issue with my instance.

I'd really like to get this 5.2.7 instance working until I can get it upgraded.

FWIW, the only custom variable set in the nagios.cfg is "enable_environment_macros=1".


Thanks,

Another quick note regarding 'enable_environment_macros=1"

I set that in the working 5.3.3 instance (default is/was 0)-- made no difference to its correct handling of the USER macros.

I think this can be considered 'resolved'.

I went a step further and applied my config, even though the "Test Check Command" was not running the Service check correctly.

The check does indeed work as needed.

The test check isn't always accurate in variable expansion.
