Per-cluster metric for whether or not the circuit breaker is brought on. If any nodes return a worth of 1 for KNNCacheCapacityReached, this benefit will likely return one. This metric is just applicable to approximate k-NN research.
This function is then assumed by Amazon OpenSearch Ingestion pipelines making sure that the best security posture is always maintained when shifting the data from resource to location.
This metric is just not suitable and might be overlooked. The support won't use grasp nodes as facts nodes.
Cluster configuration adjustments might interrupt these functions just before completion. We advise that you simply utilize the /_tasks operation together with these functions to validate that the requests accomplished successfully.
The volume of follower indexes that did not be created by a replication rule when there was a matching sample. This problem may possibly arise due to a network concern on the distant cluster, or perhaps a security difficulty (i.e. the associated part doesn't have authorization to begin replication).
Cluster configuration changes may possibly interrupt these operations before completion. We endorse which you utilize the /_tasks Procedure together with these operations to verify that the requests done successfully.
HotToWarmMigrationSuccessLatency The common latency of profitable hot to warm migrations, which includes time put in inside the queue.
The entire number of research requests for every minute for all shards on a data node. Only one get in touch with on the _search API could possibly return outcomes from a number of shards. If five of these shards are on a single node, the node would report 5 for this metric, Although the shopper only designed one particular request.
Amazon EventBridge delivers a around actual-time stream of method functions that describe variations with your OpenSearch Assistance domains.
The number of rejected OpenSearch support duties while in the search thread pool. If this number constantly grows, take into consideration scaling your cluster.
Failures suggest which the grasp node is unreachable in the source node. They are generally the result of a community connectivity concern or an AWS dependency problem.
Alerts and notifications are essential for proactive monitoring and responding speedily to faults or anomalies. OpenSearch enables us to create alerts dependant on unique circumstances throughout the “Alerting” feature.
The number of replication transportation requests on the leader domain. Transportation requests are internal and occur each time a replication API operation is named.
Per-node metric for the quantity of graphs which were evicted from the cache because of memory constraints or idle time. Specific evictions that happen as a consequence of index deletion aren't counted. This metric is just suitable to approximate k-NN lookup.
