[Feature request] WISHLIST Switch/router interface down without alarm

I am asking fellow PRTG users to support this feature request please. The Paessler Development Team are willing to implement providing other customers like the expanded functionality described below.

On a router or switch, I would like to be able to see which interfaces are disconnected. This is very useful and PRTG does have the ability to show an interface as connected or disconnected, when the interface sensor 'Connection State Handling = Show alarm when disconnected'.

Unfortunately, it is not possible to do this without generating an alarm. To prevent an alarm for a down interface, it must configured to have a Connection State Handling = Ignore disconnected status, but this eliminates the link state from the PRTG user-interface. i.e. you cannot tell that an interface is disconnected.

The proposed setting 'Do not show alarm when disconnected' solves this need. I would recommend black or grey as the color to denote a port that is disconnected and has not generated an alarm.

The interface I am describing is 'allowed' to be down and should not require any ongoing administration in PRTG. The link state is informational and useful in researching events. E.g. Unused switch ports in a server room that come online at a later date; researching a server issue and looking to see if there was a link loss; user computer connections that are down if they power off. Note: The suggested functionality should not be confused with a down 'acknowledged' alarm, as this requires manual intervention and a persistent alarm states.

Furthermore, creating sensors for unused (down) interfaces does not have to be driven by a reoccurring auto-discover of the device. Simply creating sensors for all up and down interface during the initial auto-discover and defaulting to the proposed setting 'Do not show alarm when disconnected' solves this need. This also eliminates the need to add and delete sensors as ports are assigned and unassigned to servers.

Let me know what you think. Thank you for your consideration on this.

Hi,

You are saying that:

The suggested functionality should not be confused with a
down 'acknowledged' alarm ,as this requires manual intervention

Is it not possible to automatically show this down sensor as a down-acknowledged sensor in the sensor settings tab? I know that PING sensors have this option.

If this option is not available, it is also possible to setup a http notification that automatically sets the sensor to down-acknowledged when the sensor goes down.

Thanks for the reply PRTGToolsFamily. That's probably only a partial work around to this feature gap.

The purpose of the feature idea is that an alarm should not be generated. Down-acknowledge is an alarm, where-as an interface that is disconnected is the 'state' of the interface. The ability to control if an alarm is generated can be seperated by adding this third option to the two that already exist, as shown below.

What do you think?

Connection State Handling:

  1. Show alarm when disconnected
  2. Do not show alarm when disconnected <-- Proposed new feature
  3. Ignore disconnected status

I was just thinking about how to track if interfaces are up/down.I just want a historical log of this for most interfaces.

Core network links I do want the sensor to go down, but if someone turns off a printer I really don't want an alarm. Your suggestion is perfect.

Thanks

I tried that, but it said I needed "at least a 15 reputation" to upvote.
