Hi Lukas,

Internally we refer to these probes as not-reporting and I agree that a notification would be useful.

These would then be sent if the probe:
- does not have system-ipv4-works AND system-ipv6-works tags
- does have a system-ipv4-doesnt-work OR system-ipv6-doesnt-work tag

Question is if these emails should be send again after for instance 24 hours or a week or?

As I am working on emails lately, I will add this notification to my list.

Cheers,
Johan

Hello,

currently notifications are configurable for the event when a probe is
disconnected; however when a probes remains connected but stops
working (loosing or no having either system-ipv4-works and
system-ipv6-works tags), we are blind.

I have written a monitor script to query the API for this, to get this
notification but I'm wondering if it would be possible to implement
this at RIPE. The system-<AF>-works tags are already there.

Software bugs and I guess HW issues can trigger hung probes that
remain connected. It's hard to find out, unless one is specifically
looking for it or specifically expecting the result of a single probe
in a measurement.
