Scaling Elasticsearch and Logstash services to accommodate heavy indexing, queries, or both

When your system runs a heavy load, this can affect performance. For example, if you have Spark applications that complete but metrics are slow to display or appear in visualizations (that is, there is a delay in displaying the performance charts under Workload > Instance Groups > Applications > Performance in the cluster management console). To resolve this heavy load issue and to improve performance for the metrics and visualizations, scale up the Elastic Stack services instances to accommodate these heavy loads.


To scale up service instances, see Scaling Conductor services.
