This commit replaces the previous NotifyInfo provider with the new
nflog package. It needs adjustments in the behavior of the deduping
stage.
The nflog stores notification digests per receiver per alert aggregation
group rather than one entry for alert per receiver. This drastically
reduces the number of entries and removes interference
across aggregation groups.
This commit removes the dependency on model.Silence for the internal
Silence type, uses UUIDs instead of uint64s and clarifies invariants
around timestamp handling.
The created_at timestamp is removed for the time being.
Initial testing has shown BoltDB in plain usage to be a bottleneck
at a few thousand alerts or more (especially JSON decoding.
This commit actually makes them purely memory as a temporary solution.
Previously, the tests would listen on all available interfaces.
Instead, have the tests use localhost only; using all available
interfaces is unnecessary.
On Mac OS X with the builtin firewall enabled, it triggers annoying
prompts to allow the tests to listen on all interfaces.
This commit changes the notification grouping behavior
to simply send all alerts of a group as soon as a single
one of them needs updating.
This fixes a critical bug which caused erroneous resolved
notifications to be sent.
