Feature Request - Flapping and Sleeping nuances

Is your feature request related to a problem? Please describe

Hello, again! The flapping and sleeping features are excellent features, however, as they currently stand they are a little fickle.

Regarding flapping - some devices, in my case Apple iPads, are notorious for hanging while they are in their deepest sleep to the point they will actually temporarily jump off the network when they're idle/not in use. But then, they will check-in with the network within several minutes. This device behavior is triggering the flapping status.

Regarding sleeping - I believe this one is a much more simple fix. As it stands, when the device goes into sleep, they are still counted as "down" in the device counter at the top of the page. When I click on the counter, no devices are shown in the list area, but the counter remains showing there is a down device.

Describe the solution you'd like

For flapping - A general master switch in the settings to turn on/off flapping would be nice. Or perhaps more granular control, like a general setting where a user can increase/decrease the amount of disconnects/reconnects before a device shows the flapping status. Even better if this can be initiated on a per device basis.

For sleeping - remove sleeping devices from the "down" counter. Devices should only be counted as down if they reach a down status.

Describe alternatives you've considered

I've changed sleep-time and down-time intervals, but those settings can't help the underlying problem of a device being counted as down when it's in sleeping status.

There currently isn't any flapping settings, that I've seen, that can change it's behavior.

Anything else?

Am I willing to test this? 🧪

• I will do my best to test this feature on the netlertx-dev image when requested within 48h and report bugs to help deliver a great user experience for everyone and not to break existing installations.

Can I help implement this? 👩‍💻👨‍💻

• Yes
• No

Hi @mmstano ,

Thanks for the feedback. I hear you.

Flapping:

I do not want to allow flapping defaults to change as I want to keep it standard across all instances. If you have a proposal how a flapping device should be detected, contrary to the current 3 status changes in the last hour, please let me know, and I will re-evaluate the defaults. A standard definition across all instances makes debugging and maintenance easier.

Sleeping:

I think this was caused by a bug also causing #1569 . Can you test the dev image? See instructions below.

This should be fixed in the next release.
It would be great if you could test the ghcr.io/netalertx/netalertx-dev Docker image in ~15 minutes (or once the latest GitHub Action finishes).

⚠️ Please back up everything first, or ideally spin up a separate container with its own DB and config (a copy of your current setup), as database changes may occur.

After updating:

• Click the 🔄 refresh button in the blue header at the top
• Hard refresh your browser cache (shift + reload) to force js and css files reload

Disclaimer: Running the dev container long-term may lead to data loss, as upgrade paths are not guaranteed.

Thanks in advance,
