Google Vertex AI Index metrics

A Vertex AI index holds the vectors that an index endpoint queries. The metrics collected for an index cover streaming updates, which add and remove datapoints while the index continues to serve queries. Ensure your cloud platform is configured in SolarWinds Observability SaaS to collect this service's data. See Add a GCP cloud account.

Many of the collected metrics from Vertex AI Index 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 Vertex AI Index metrics in the Metrics Explorer, type aiplatform.googleapis.com/matching_engine/stream_update in the search box.

Metric	Unit	Description
sw.metrics.healthscore	Percent (%)	Health state. The health state provides real-time insight into the overall health and performance of your monitored entities. The health state is determined based on anomalies detected for the entity, alerts triggered for the entity's metrics, and the status of the entity. The health state is displayed as one of the following four states and colors: Good, Moderate, Bad, or Unknown. You can determine the impact of the alerts, anomalies, and statuses on the health of an entity type by going to Settings > Health, and selecting a specific entity type. You can also customize the impact. To view the health of Google Vertex AI Index entities in the Metrics Explorer, filter the sw.metrics.healthscore metric by entity_types and select gcpvertexaiindex.
gcp.aiplatform.googleapis.com.matching_engine.stream_update.requestCount	Count per second	Number of streaming update requests to the index.
gcp.aiplatform.googleapis.com.matching_engine.stream_update.latencies	Milliseconds (ms)	Latency distribution for streaming update requests to the index.
gcp.aiplatform.googleapis.com.matching_engine.stream_update.datapointCount	Count	Number of datapoints added to or removed from the index by a streaming update.
