There is now a device health section at the top of the Clients page, I personally think is it an excellent addition, though it misses cameras out at the moment:
For a network with an HA pair of MXs it does report them both:
Interestingly I have it on shard 184 but not shard 199. Possibly still rolling out...
It's also missing celluar gateway.
This has been on some shards for a good month. Still missing on others.
Not available on my shard either.
Just saw partial of this on my dashboard. Cannot wait for full roll out.
I would love to see a menu option called Health where you can configure some of these options (separate but related to alerts).
