Connect alarms

EDA Connect, both Core and the plugins, can raise alarms if something is wrong and an action is needed by the administrator. These alarms are raised through the standard EDA Alarm system.

Connect service alarms

When a plugin is registered with Connect with a HeartbeatInterval greater than or equal to one, Connect's plugin controller periodically evaluates whether the plugin is sending heartbeats as promised.

If a plugin fails to do so, the ConnectPlugin's status includes a stale=true field and the following alarm is raised:

apiVersion: core.eda.nokia.com/v1 
kind: Alarm 
metadata: 
  name: <plugin_name>-stale-alarm 
  namespace: <plugin_namespace> 
spec: 
  description: This alarm is raised when a plugin fails to send heartbeats within the HeartbeatInterval it is registered with. 
  kind: ConnectPluginStale 
  name: ConnectPluginStale-<plugin_name> 
  objectKind: ConnectPlugin 
  objectName: <plugin_name> 
  probableCause: This alarm is likely to be triggered when the plugin has lost connection to EDA, or when the plugin is in a bad state. 
  remedialAction: Check the plugin's connection to the EDA system. If there are no connection issues, try restarting the plugin. 
  severity: critical
