This change extracts setting logic directly into the silence state.
Only assigning of a UUID and mesh propagation are left directly to
the mesh provider.
Validity of modifying silence state extracted into its own method.
Test for state modification added.
This add a Procfile that can be run with `goreman start`. It starts
three Alertmanagers and one webhook receiver. The webhook receiver
simply reflects sent messages.
The send_alerts.sh script simulates a set of alerts sent by a Prometheus
server to all Alertmanagers at once.
This commit implements a wait period before actually dispatching
notifications. The backoff linearly depends on the UID order of
participating peers.
This gives the gossip state time to catch up and avoids duplicate
notifications while ensuring that every peer notifies eventually.
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.
Currently, even if all alerts within a group are silenced, the group
summary still appears. This can take up a lot of space when many alerts
are silenced.
If all alerts in a group are silenced and 'Hide silences' is checked,
hide the empty group.
bindata was updated by running:
make assets format
Add default VictorOpsAPIURL
Add VictorOps default config
Add VictorOpsConfig struct in notifiers
Add new template tags for victorops
Add notifications logic for victorops
Compiled template tags with make assets
Remove common labels from entity_id template
Set messageType default value to CRITICAL
Recovery messageType is not configurable anymore. Firing state only allows specific keys
Make assets
Using log.Debugf
EntityID should not be configureable
Remove entity_id from template
Use GroupKey(ctx) as entity_id
Improve debug logging
Fix type of entity_id
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.
