Experimental Open source

database_observability.sql_server

EXPERIMENTAL: This is an experimental component. Experimental components are subject to frequent breaking changes, and may be removed with no equivalent replacement. To enable and use an experimental component, you must set the stability.level flag to experimental.

database_observability.sql_server connects to a Microsoft SQL Server instance and collects observability data across every accessible user database on that instance. The component forwards this data as log entries to Loki receivers and exports targets for Prometheus scraping.

Usage

Alloy
database_observability.sql_server "<LABEL>" {
  data_source_name = <DATA_SOURCE_NAME>
  forward_to       = [<LOKI_RECEIVERS>]
}

Arguments

You can use the following arguments with database_observability.sql_server:

NameTypeDescriptionDefaultRequired
data_source_namesecretData Source Name for the SQL Server instance to connect to.yes
forward_tolist(LogsReceiver)Where to forward log entries after processing.yes
targetslist(map(string))List of external targets to scrape.no
disable_collectorslist(string)A list of collectors to disable from the default set.no
enable_collectorslist(string)A list of collectors to enable on top of the default set.no
exclude_schemaslist(string)A list of schemas to exclude from monitoring, on top of the always-excluded system schemas sys and information_schema.["alloydbadmin", "alloydbmetadata", "azure_maintenance", "azure_sys", "cloudsqladmin", "rdsadmin"]no
exclude_databaseslist(string)A list of databases to exclude from monitoring, on top of the always-excluded system databases master, model, msdb, and tempdb.["alloydbadmin", "alloydbmetadata", "azure_maintenance", "azure_sys", "cloudsqladmin", "rdsadmin"]no

The following collectors are configurable:

schema_details

NameTypeDescriptionDefaultRequired
collect_intervaldurationHow frequently to collect information from database."1m"no

The collector scans every database that the login can access on the instance and collects schema details from each. Only databases where the login has CONNECT access to catalog views are collected.

Example

Alloy
database_observability.sql_server "orders_db" {
  data_source_name = "sqlserver://user:pass@server:1433"
  forward_to       = [loki.write.logs_service.receiver]
}

loki.write "logs_service" {
  endpoint {
    url = sys.env("<GRAFANA_CLOUD_HOSTED_LOGS_URL>")
    basic_auth {
      username = sys.env("<GRAFANA_CLOUD_HOSTED_LOGS_ID>")
      password = sys.env("<GRAFANA_CLOUD_RW_API_KEY>")
    }
  }
}

Replace the following:

  • <GRAFANA_CLOUD_HOSTED_LOGS_URL>: The URL for your Grafana Cloud hosted logs.
  • <GRAFANA_CLOUD_HOSTED_LOGS_ID>: The user ID for your Grafana Cloud hosted logs.
  • <GRAFANA_CLOUD_RW_API_KEY>: Your Grafana Cloud API key.
