OpenSearch Collection metrics

Amazon OpenSearch is a managed service that makes it easy to deploy, operate, and scale OpenSearch clusters in the AWS Cloud. Ensure your cloud platform is configured in SolarWinds Observability SaaS to collect this service's data. See Add an AWS cloud account. CloudWatch metrics must also be enabled for this service in the AWS Console for the metric data to be available.

Many of the collected metrics from OpenSearch Collection entities are displayed as widgets in SolarWinds Observability explorers; additional metrics may be collected and available in the Metrics Explorer. You can also create an alert for when an entity's metric value moves out of a specific range. See Entities in SolarWinds Observability SaaS for information about entity types in SolarWinds Observability SaaS.

The following table lists some of the metrics collected for these entities. To see the OpenSearch Collection metrics in the Metrics Explorer, type AWS.AOSS in the search box.

Metric Units Description
sw.metrics.healthscore Percent (%)

Health score. A health score provides real-time insight into the overall health and performance of your monitored entities. The health score is calculated based on anomalies detected for the entity, alerts triggered for the entity's metrics, and the status of the entity. The health score is displayed as a single numerical value that ranges from a Good (70-100) to Moderate (40-69) to Bad (0-39) distinction.

To view the health score for OpenSearch Collection entities in the Metrics Explorer, filter the sw.metrics.healthscore metric by entity_types and select awsopensearchcollection.
AWS.AOSS.2xx Count The number of 2XX HTTP status code responses. These indicate successful requests.
AWS.AOSS.3xx Count The number of 3XX HTTP status code responses. These indicate redirections
AWS.AOSS.4xx Count The number of 4XX HTTP status code responses. These indicate client errors, such as bad requests or unauthorized access.
AWS.AOSS.5xx Count The number of 5XX HTTP status code responses. These indicate server errors, such as server overload or server-side issues.
AWS.AOSS.ActiveCollection Count

Indicates whether a collection is active. A value of 1 means the collection is in an ACTIVE state. This metric is emitted upon successful creation of a collection and remains 1 until the collection is deleted.
AWS.AOSS.DeletedDocuments Count The total number of documents that have been deleted from the collection. This metric increases after delete requests are processed and decreases after index segments are merged within the cluster.
AWS.AOSS.HotStorageUsed bytes The amount of storage used for hot data, which is data that is frequently accessed and needs to be readily available.
AWS.AOSS.IndexingOCU Count The number of OpenSearch Compute Units (OCUs) used to ingest collection data. This metric applies at the account level and helps monitor the compute resources used for indexing.
AWS.AOSS.IngestionDataRate Gigabytes per second (GB/s)

The indexing rate in GiB per second to a collection or index. This metric only applies to bulk indexing requests and helps track the data ingestion speed.
AWS.AOSS.IngestionDocumentErrors Count

The number of document ingestion errors that occur while indexing data. This metric helps in identifying issues during the data ingestion process.
AWS.AOSS.IngestionDocumentRate Count per second

The rate per second at which documents are being ingested to a collection or index. This metric applies to bulk indexing requests.
AWS.AOSS.IngestionRequestErrors Count

The total number of bulk indexing request errors to a collection. This metric is emitted when a bulk indexing request fails for any reason, such as an authentication or availability issue.
AWS.AOSS.IngestionRequestLatency seconds (s) The time it takes for ingestion requests to be processed and completed. This metric measures the latency from the start to the end of the ingestion request.
AWS.AOSS.IngestionRequestRate Count per second

The rate at which ingestion requests are being made to a collection or index. This metric tracks the number of requests per unit of time.
AWS.AOSS.IngestionRequestSuccess Count

The number of successful ingestion requests to a collection or index. This metric counts the requests that were successfully processed without errors.
AWS.AOSS.SearchableDocuments Count The total number of searchable documents in the OpenSearch domain.
AWS.AOSS.SearchOCU Count The number of OpenSearch Compute Units (OCUs) used for search operations.
AWS.AOSS.SearchRequestErrors Count per minute

The total number of errors encountered during search requests.
AWS.AOSS.SearchRequestLatency milliseconds (ms) The average latency (response time) for search requests.
AWS.AOSS.SearchRequestRate Count per minute

The rate at which search requests are being made.
AWS.AOSS.StorageUsedInS3 bytes The amount of storage used in Amazon S3 for OpenSearch data.
