prometheus.exporter.mssql

The prometheus.exporter.mssql component embeds sql_exporter for collecting stats from a Microsoft SQL Server.

Usage

river
prometheus.exporter.mssql "LABEL" {
    connection_string = CONNECTION_STRING
}

Arguments

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

NameTypeDescriptionDefaultRequired
connection_stringsecretThe connection string used to connect to an Microsoft SQL Server.yes
max_idle_connectionsintMaximum number of idle connections to any one target.3no
max_open_connectionsintMaximum number of open connections to any one target.3no
timeoutdurationThe query timeout in seconds."10s"no

The sql_exporter examples show the format of the connection_string argument:

conn
sqlserver://USERNAME_HERE:PASSWORD_HERE@SQLMI_HERE_ENDPOINT.database.windows.net:1433?encrypt=true&hostNameInCertificate=%2A.SQL_MI_DOMAIN_HERE.database.windows.net&trustservercertificate=true

Blocks

The prometheus.exporter.mssql 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.

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

Debug information

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

Debug metrics

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

Example

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

river
prometheus.exporter.mssql "example" {
  connection_string = "sqlserver://user:pass@localhost:1433"
}

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

prometheus.remote_write "demo" {
  endpoint {
    url = PROMETHEUS_REMOTE_WRITE_URL

    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.
