HTTPS endpoints

The HTTPS service exposes general-purpose endpoints for interacting with your database. While most endpoints require authentication with either certificates or the dbadmin's password, the following endpoints for documentation do not:

  • /v1/version
  • /swagger/ui
  • /swagger/{RESOURCE}
  • /api-docs/oas-3.0.0.json

To view a list of all endpoints, enter the following URL in your browser:

https://database_hostname_or_ip:8443/swagger/ui?urls.primaryName=server_docs

/v1/metrics (GET)

Vertica exposes time series metrics for Prometheus monitoring and alerting. These metrics create a detailed model of your database behavior over time to provide valuable performance and troubleshooting insights.

To retrieve time series metrics for a node, send a GET request to /v1/metrics:

$ curl https://host:8443/v1/metrics \
    --key path/to/client_key.key \
    --cert path/to/client_cert.pem \

Vertica scrapes metrics from the node and outputs the metrics in Prometheus text-based exposition format. This format applies context-specific labels to each metric to help group metrics when you visualize your data. It also describes the metric type—Vertica provides counter, gauge, and histogram metric types. The following example outlines the output format:

# HELP metric-name metric-defintion
# TYPE metric-name metric-type
metric-name{label-key="label-value"[, ...]} metric-value

For example, the following example shows a snippet of the request response that provides details about the vertica_resource_pool_memory_size_actual_kb metric:

$ curl https://10.20.30.40:8443/v1/metrics \
    --key path/to/client_key.key \
    --cert path/to/client_cert.pem \
...
# HELP vertica_resource_pool_memory_size_actual_kb Current amount of memory (in kilobytes) allocated to the resource pool by the resource manager.
# TYPE vertica_resource_pool_memory_size_actual_kb gauge

To get a cluster-wide view of your metrics, you must call the /v1/metrics endpoint on each node in your cluster.
