The OcientAIQ™ Unified Data Platform provides an official Datadog® integration that collects performance metrics from the Prometheus®-compatible /metrics endpoint and forwards them to the Datadog cloud platform. Use this integration to monitor cluster health, query performance, ingestion throughput, and storage capacity alongside your other infrastructure in Datadog. For installation and general configuration instructions, see the Datadog Ocient Integration page. This page covers Ocient®-specific configuration guidance that supplements the Datadog documentation.

Prerequisites

You must have:
  • Datadog Agent version 7 or later installed on a host that can reach the Ocient cluster.
  • Network access from the Datadog Agent host to port 9090 on each Ocient node that you want to monitor.
  • The Ocient integration installed on the Agent (agent integration install -t datadog-ocient==1.0.0).

Filter Metrics by Level

The Ocient /metrics endpoint supports a level query parameter that controls which metrics the endpoint returns. Append ?level=info to the openmetrics_endpoint URL to limit collection to production-level metrics, reducing cardinality and Datadog cost. The supported levels are info (production metrics), debug (all metrics including internal diagnostics), and default (baseline set). This configuration collects only info-level metrics from a single SQL Node.
conf.d/ocient.d/conf.yaml

Monitor Multiple Nodes

The integration scrapes one endpoint for each instance. To monitor an entire cluster, add one instance per node in the configuration file. Each Ocient node exposes its own metrics independently. SQL Nodes expose query lifecycle metrics (cmdcomp_*), while Foundation Nodes expose storage and ingestion metrics (e.g., local_storage_service_*, stream_loader_*). This configuration monitors one SQL Node oc1-sql0 and two Foundation Nodes, oc1-lts0 and oc1-lts1, in the same cluster, collecting info-level metrics from each.

Name Metrics in Datadog

Metrics appear in Datadog with the prefix ocient. followed by the metric name from the /metrics endpoint. For example, the endpoint metric cmdcomp_queries becomes ocient.cmdcomp_queries in Datadog. Datadog removes the _total suffix for counter metrics and replaces it with a .count suffix for submission. For example, stream_loader_api_push_rows_requests_total becomes ocient.stream_loader_api_push_rows_requests.count. For a complete reference of available metrics, their types, labels, and descriptions, see the Prometheus Metrics Endpoint — Key Metrics Reference.

Service Checks

The integration reports a service check named ocient.openmetrics.health that indicates the reachability of the configured openmetrics_endpoint endpoint. The OK value indicates successful scraping, whereas the CRITICAL value indicates the endpoint is unreachable.

Troubleshooting

Troubleshoot common error messages when you work in Datadog:
  • Agent cannot reach the endpoint. — Verify that the host running the Agent can connect to port 9090 on the target Ocient node. The /metrics endpoint does not require authentication. Execute this curl command on the Agent host to confirm that the endpoint is reachable and returns metric data.
    If the command returns metric lines starting with # (comment headers) or metric name-value pairs, the endpoint is accessible. An empty response or connection error indicates a network or firewall issue.
  • No metrics appear in Datadog. — Execute the agent check ocient command and inspect the output for errors. Common issues include incorrect endpoint URLs, typos in the hostname or port, and firewall rules blocking port 9090.
  • High metric cardinality. — Use the level=info query parameter to limit collection to production-level metrics. Alternatively, use the exclude_metrics option in the conf.d/ocient.d/conf.yaml file to drop high-cardinality metric families, such as jemalloc_*.
  • Metric names differ from the endpoint. — Datadog applies the ocient. namespace prefix and converts counter suffixes. For details, see Name Metrics in Datadog.
