Before you decide to use automated equipment to produce index templates, you'll be able to confirm that none exist already using the OpenSearchQuery Lambda function.
The quantity of queued duties from the UltraWarm research thread pool. In the event the queue dimensions is consistently substantial, think about introducing more UltraWarm nodes.
The full amount of requests rejected on Major shards resulting from distant storage and replication stress. This is certainly calculated starting from the last OpenSearch Support process startup.
The no OpenSearch support cost space for details nodes within the cluster. Sum exhibits full totally free space for your cluster, but you need to depart the time period at one moment to acquire an precise benefit. Minimum and Highest show the nodes With all the the very least and many no cost House, respectively.
The amount of queued responsibilities within the index thread pool. Should the queue dimensions is consistently higher, think about scaling your cluster. The utmost index queue sizing is 200.
Cluster configuration variations could interrupt these functions just before completion. We propose you use the /_tasks Procedure alongside Using these functions to confirm which the requests concluded properly.
