Reporting Aggregated Events and Performance Data in a Cluster
When aggregated events or performance data metrics are collected by a node in a cluster, that node sends the event or metric to its shared cache where it awaits processing.
At each interval, the senior node scans the shared cache for the events and metrics stored there. The senior node then notifies all the nodes in the cluster of the stored metrics and events. The first node to respond to the senior node's notification processes the event or metrics, reporting them to CentraSite and the other nodes in the cluster disregards the notification. Any of the nodes in the cluster are eligible to send the metrics to CentraSite.
Step | Description |
1 | The aggregated events or metrics are produced by any or all nodes in the cluster and each node that collected the events and metrics publishes them to its own shared cache. |
2 | At each tick interval, the senior node scans the events and metrics in the shared cache. If the interval for processing the metrics or events has been met, the senior node notifies all the nodes in the cluster that the events or metrics are ready to be processed. |
3 | The first node to respond to the senior node's notification processes the event or metrics and reports them to CentraSite. Any of the nodes in the cluster are eligible to send the metrics to CentraSite. |
