thresholds file with only 3 fields does not work properly

[adamobcn]

Describe the bug

A template with only 3 fields in its thresholds file does not work properly.

Example: with power thresholds of cisco templates:
PsuStatus : red : critical|not functioning
PsuStatus : yellow : warning|shutdown|not present
PsuStatus : green : normal

Adding any thresholds message in the 4th field fixes the issue:

Example:
PsuStatus : red : critical|not functioning : Error
PsuStatus : yellow : warning|shutdown|not present : Warning
PsuStatus : green : normal : Ok

Expected behaviour

Global color should be "red"

red Wed Aug 06 11:52:07 2025

Alarming on (Switch 1 - Power Supply A,Switch 1 - Power Supply B)

PSU Type	PSU state
Switch 1 - Power Supply A	&red critical
Switch 1 - Power Supply B	&green normal

Actual behaviour

Global color is "green" when you have a PSU "red"

green Wed Jul 30 03:30:21 2025

Alarming on (Switch 1 - Power Supply A,Switch 1 - Power Supply B)

PSU Type	PSU state
Switch 1 - Power Supply A	&red critical
Switch 1 - Power Supply B	&green normal

Server configuration

Xymon version:
Xymon 4.3.30

Perl version:
v5.16.3

Devmon version:
v0.25.03

Note that there is the same behavior with custom thresholds added from DEVMON tag (even if you have 4 fields in the template).

Example with a simple template:

==> var/templates/cisco-nexus/memory/exceptions <==

==> var/templates/cisco-nexus/memory/message <==
Thresholds: yellow:{cseSysMemoryUtilization.thresh:yellow}%, red:{cseSysMemoryUtilization.thresh:red}%

Memory Utilization: {cseSysMemoryUtilization.color}{cseSysMemoryUtilization}%


==> var/templates/cisco-nexus/memory/oids <==
cseSysMemoryUtilization : 1.3.6.1.4.1.9.9.305.1.1.2.0 : leaf

==> var/templates/cisco-nexus/memory/thresholds <==
cseSysMemoryUtilization : yellow : 55 : Memory load is high
cseSysMemoryUtilization : red    : 95 : Memory load is very high

==> var/templates/cisco-nexus/memory/transforms <==

The result is fine with the 4th field:

yellow Fri Aug 08 11:56:31 2025

Thresholds: yellow:55%, red:95%

Memory Utilization: &yellow 64%

But if we add custom thresholds, the color is always "green".

With thresholds added on DEVMON tag DEVMON:thresh(memory;cseSysMemoryUtilization;r:90;y:45) and yellow alert inside:

green Fri Aug 08 11:52:12 2025

Thresholds: yellow:45%, red:90%

Memory Utilization: &yellow 64%

With thresholds added on DEVMON tag DEVMON:thresh(memory;cseSysMemoryUtilization;r:50;y:45) and red alert inside:

green Fri Aug 08 11:54:40 2025

Thresholds: yellow:45%, red:50%

Memory Utilization: &red 64%

Thanks for this info:
I see this line in the code:
dm_tests.pm: 3027 if ( ( defined $oid_msg ) and ( not $no_global_wcolor{$oid} ) and ( $oid_msg ne '' ) ) {
And seems to me that the behavior you described is because of part: and ( $oid_msg ne '' )

• Seems to me that it is apply to table and leaf (consistent)
  -> so this seems to imply that if the error message is not set the error is not reported globally. But i do not remember why I have done it like this. A least this should be documented.
  If you can confirm that this is this line ?
  I will try to think if this test is necessary or not and try to remember the context where it can be usefull if any

Hello,

Yes, it seems due to this line and could be the root cause of the initial issue.
But I don't understand how it affects the custom thresholds added from DEVMON tag.
