The prometheus.exporter.oracledb component embeds oracledb_exporter for collecting statistics from a OracleDB server.


prometheus.exporter.oracledb "LABEL" {
    connection_string = CONNECTION_STRING


The following arguments can be used to configure the exporter’s behavior. Omitted fields take their default values.

connection_stringsecretThe connection string used to connect to an Oracle Database.yes
max_idle_connsintNumber of maximum idle connections in the connection pool.0no
max_open_connsintNumber of maximum open connections in the connection pool.10no
query_timeoutintThe query timeout in seconds.5no

The oracledb_exporter running documentation shows the format and provides examples of the connection_string argument:



The prometheus.exporter.oracledb component does not support any blocks, and is configured fully through arguments.

Exported fields

The following fields are exported and can be referenced by other components.

targetslist(map(string))The targets that can be used to collect exporter metrics.

For example, the targets can either be passed to a discovery.relabel component to rewrite the targets’ label sets, or to a prometheus.scrape component that collects the exposed metrics.

The exported targets will use the configured in-memory traffic address specified by the run command.

Component health

prometheus.exporter.oracledb is only reported as unhealthy if given an invalid configuration. In those cases, exported fields retain their last healthy values.

Debug information

prometheus.exporter.oracledb does not expose any component-specific debug information.

Debug metrics

prometheus.exporter.oracledb does not expose any component-specific debug metrics.


This example uses a prometheus.scrape component to collect metrics from prometheus.exporter.oracledb:

prometheus.exporter.oracledb "example" {
  connection_string = "oracle://user:password@localhost:1521/orcl.localnet"

// Configure a prometheus.scrape component to collect oracledb metrics.
prometheus.scrape "demo" {
  targets    = prometheus.exporter.oracledb.example.targets
  forward_to = [prometheus.remote_write.demo.receiver]

prometheus.remote_write "demo" {
  endpoint {

    basic_auth {
      username = USERNAME
      password = PASSWORD

Replace the following:

  • PROMETHEUS_REMOTE_WRITE_URL: The URL of the Prometheus remote_write-compatible server to send metrics to.
  • USERNAME: The username to use for authentication to the remote_write API.
  • PASSWORD: The password to use for authentication to the remote_write API.
