Discovery rule inclusion filter not working with regexp on interface names

Hello,

I’m facing an issue with a discovery rule in Centreon where the inclusion filter does not seem to work as expected.

Context:

  • I created a discovery rule to include only interfaces with names containing StackPort.

  • My inclusion rule is configured as:

    • Macro: $name$

    • Regexp: ^StackPort*

Expected behavior:
Only interfaces like StackPort1, StackPort2, etc. should be discovered.

Actual behavior:
When I run the discovery command manually, I can see interfaces such as:

'StackPort2' [speed = 160000][status = up][id = 124][type = propVirtual]

However, when I perform a manual scan from the Centreon UI, the inclusion filter does not seem to apply, and other interfaces are still discovered.

Command used to list interfaces in CLI :

sudo -u centreon-engine /usr/lib/centreon/plugins/centreon_cisco_standard_snmp.pl --plugin='network::cisco::standard::snmp::plugin' --mode=list-interfaces --hostname='10.0.0.8' --snmp-version='2c' --snmp-community='public' --disco-show

...

Questions:

  1. Is my regular expression ^StackPort* correct for matching interfaces like StackPort2?

  2. Is there any known limitation or specific behavior with $name$ macros in inclusion rules?

Any help would be appreciated.
