Monitoring & Telemetry
Qdrant exposes its metrics in Prometheus/OpenMetrics format, so you can integrate them easily
with the compatible tools and monitor Qdrant with your own monitoring system. You can
use the /metrics endpoint and configure it as a scrape target.
Metrics endpoint: http://localhost:6333/metrics
The integration with Qdrant is easy to configure with Prometheus and Grafana.
Monitoring multi-node clusters
When scraping metrics from multi-node Qdrant clusters, it is important to scrape from each node individually instead of using a load-balanced URL. Otherwise, your metrics will appear inconsistent after each scrape.
Monitoring in Qdrant Cloud
To scrape metrics from a Qdrant cluster running in Qdrant Cloud, note that an API key is required to access /metrics. Qdrant Cloud also supports supplying the API key as a Bearer token, which may be required by some providers.
Exposed metrics
Each Qdrant server will expose the following metrics.
| Name | Type | Meaning |
|---|---|---|
| app_info | gauge | Information about Qdrant server |
| app_status_recovery_mode | gauge | If Qdrant is currently started in recovery mode |
| collections_total | gauge | Number of collections |
| collections_vector_total | gauge | Total number of vectors in all collections |
| collections_full_total | gauge | Number of full collections |
| collections_aggregated_total | gauge | Number of aggregated collections |
| rest_responses_total | counter | Total number of responses through REST API |
| rest_responses_fail_total | counter | Total number of failed responses through REST API |
| rest_responses_avg_duration_seconds | gauge | Average response duration in REST API |
| rest_responses_min_duration_seconds | gauge | Minimum response duration in REST API |
| rest_responses_max_duration_seconds | gauge | Maximum response duration in REST API |
| grpc_responses_total | counter | Total number of responses through gRPC API |
| grpc_responses_fail_total | counter | Total number of failed responses through REST API |
| grpc_responses_avg_duration_seconds | gauge | Average response duration in gRPC API |
| grpc_responses_min_duration_seconds | gauge | Minimum response duration in gRPC API |
| grpc_responses_max_duration_seconds | gauge | Maximum response duration in gRPC API |
| cluster_enabled | gauge | Whether the cluster support is enabled. 1 - YES |
Cluster-related metrics
There are also some metrics which are exposed in distributed mode only.
| Name | Type | Meaning |
|---|---|---|
| cluster_peers_total | gauge | Total number of cluster peers |
| cluster_term | counter | Current cluster term |
| cluster_commit | counter | Index of last committed (finalized) operation cluster peer is aware of |
| cluster_pending_operations_total | gauge | Total number of pending operations for cluster peer |
| cluster_voter | gauge | Whether the cluster peer is a voter or learner. 1 - VOTER |
Telemetry endpoint
Qdrant also provides a /telemetry endpoint, which provides information about the current state of the database, including the number of vectors, shards, and other useful information. You can find a full documentation of this endpoint in the API reference.
Kubernetes health endpoints
Available as of v1.5.0
Qdrant exposes three endpoints, namely
/healthz,
/livez and
/readyz, to indicate the current status of the
Qdrant server.
These currently provide the most basic status response, returning HTTP 200 if Qdrant is started and ready to be used.
Regardless of whether an API key is configured, the endpoints are always accessible.
