Add filtering option in Associations section for Alert Checks

Hello,

Please, your help by adding the option "Port ifOperStatus" to the associations option list in Alert Checks. Currently, only "Port ifAdminStatus" is available but sometimes a port with admin status set to "up" may still be in "down" state if it is disconnected.

The database contains that value so I think it's posible to include it.

You can check the attached images as reference.

Thank you in advance.
