Description

This pull request introduces three new operational modes and significantly enhances several existing ones.

The new modes added are:

• auto_update: Handles automatic update checks and procedures.
• ha_cluster: Provides monitoring capabilities for High Availability clusters.
• interfaces_disco: A dedicated discovery mode designed to automatically detect and enumerate network interfaces on the target device. This mode simplifies the configuration process by dynamically identifying available interfaces rather than requiring manual definition.

Existing modes have also been updated to integrate new MIBs and data points, ensuring broader and more granular supervision coverage.

Type of change

• Patch fixing an issue (non-breaking change)
• New functionality (non-breaking change)
• Functionality enhancement or optimization (non-breaking change)
• Breaking change (patch or feature) that might cause side effects breaking part of the Software

How this pull request can be tested ?

To verify the new functionality, please follow these steps:

1. Test interfaces_disco (Discovery Mode):

   • Run the plugin with the --mode=interfaces_disco option against a target device.
   • Verify that the output lists all detected network interfaces dynamically.
   • In Centreon UI, use the service scan option.

2. Test auto_update:

   • Execute the plugin with --mode=auto_update.
   • Verify the update status report.

3. Test ha_cluster:

   • Run --mode=ha_cluster against a configured HA cluster.
   • Validate that cluster node states and synchronization status are reported correctly.
