Restart a Logstash cluster or node after modifying its configuration or when the Logstash service becomes unavailable due to an error. You perform the restart in the Elasticsearch console.
Prerequisites
Before you begin, make sure that:
-
The cluster is in the Normal state (shown in green in the console)
-
The resource usage of the cluster is not high
To check resource usage, open the Cloud Service Monitoring Dashboard page in the CloudMonitor console. The dashboard shows the following metrics for your cluster:
-
node disk usage(%)
-
node heap memory usage(%)
-
node cpu usage(%)
-
node 1m load(value)
For instructions on viewing these metrics, see Configure a custom alert policy.
Restart scope
Choose the restart scope based on your situation:
| Scope | What it restarts |
|---|---|
| Cluster restart | All nodes in the cluster |
| Node restart | A single node in the cluster |
