Application
aerospike_vector_search_batch_requests Number of batch direct requests that were rejected because of errors.
counter integer aerospike_vector_search_cluster_created_timestamp Indicates the date and time when the cluster was created.
gauge integer aerospike_vector_search_cluster_key Randomly generated 64-bit hexadecimal string to identify the AVS cluster.
gauge integer aerospike_vector_search_cluster_size Size of the cluster. Can be checked to make sure the cluster size is what you expect after adding or removing a node. Check across all nodes in a cluster.
gauge integer aerospike_vector_search_connections Number of active client connections to AVS.
counter integer aerospike_vector_search_healer_cycle Details of an AVS healer cycle. To extract relevant meaning, filter within this metric using one or more of the following filter labels.
-
typereports details of the healer as one of the following:-
cycle-timetime it takes for a healer cycle to complete -
total-timetotal time spent by the healer -
enqueue-index-innumber of items that the healer has proxied into an AVS node for re-indexing -
enqueue-index-outnumber of items that the healer has proxied out to another node for re-indexing -
enqueue-index-localnumber of items re-indexed on the node

gauge integer aerospike_vector_search_heartbeats_adjacency_size …
gauge integer aerospike_vector_search_heartbeats_received The number of heartbeats received from other cluster instances.
counter integer aerospike_vector_search_heartbeats_sent The number of heartbeats sent to other cluster instances.

gauge integer aerospike_vector_search_indexing_queue_size Queue depth of metrics currently being index by Aerospike Vector Search. The maximum queue depth is 1,000,000. Exceeding this limit results in a resource exhausted error.
This value is configured using the max-mem-queue-size property on the AVS node or the index. The default value is 1,000,000.

gauge integer aerospike_vector_search_requests Number of requests on a given Aerospike Vector Search node. Filter within this metric to extract relevant meaning. Some labels support additional filters, as noted below:
typefilters the different request types, which includequery,batch_merge,is-indexed,delete,update,exists,read, andwrite. Since inbound and outbound proxying are accounted for, this metric can be greater than the actual volume of requests.update_typeorquery_typeprovide more information about the behavior of an update or query, and can be one of the following:clientis a request from the client.localrequest performed on the node.proxy-outrequest routed out to another node.proxy-inrequest routed in from another node.
statuscan beerror,success,queued,malformed, orunauthenticated-error.
Monitoring depends on your use case. Consider monitoring for errors, queries per second (QPS), or ingest rate using this metric with filters. The following expression illustrates monitoring for QPS.

counter integer aerospike_vector_search_vector_records Number of records processed by a standalone indexer or the healer.
statuscan be one of the following:indexed- number of records successfully indexedscanned- number of records eligible to be indexedunindexed- number of records eligible that are not yet indexedbatch-merge-pending- number of records waiting to be merged into the indexreindexed- number of records re-indexed by the healer
