editPostgreSQL module
editThis module periodically fetches metrics from PostgreSQL servers.
Default metricsets are activity
, bgwriter
and database
.
Dashboard
editThe PostgreSQL module comes with a predefined dashboard showing databse related metrics. For example:
Module-specific configuration notes
editWhen configuring the hosts
option, you must use Postgres URLs of the following
format:
[postgres://][user:pass@]host[:port][?options]
The URL can be as simple as:
- module: postgresql hosts: ["postgres://localhost"]
Or more complex like:
- module: postgresql hosts: ["postgres://localhost:40001?sslmode=disable", "postgres://otherhost:40001"]
You can also separately specify the username and password using the respective
configuration options. Usernames and passwords specified in the URL take
precedence over those specified in the username
and password
config options.
- module: postgresql metricsets: ["status"] hosts: ["postgres://localhost:5432"] username: root password: test
Compatibility
editThis module was tested with PostgreSQL 9, 10, 11, 12 and 13. It is expected to work with all versions >= 9.
The PostgreSQL module supports the standard configuration options that are described in Modules. Here is an example configuration:
metricbeat.modules: - module: postgresql enabled: true metricsets: # Stats about every PostgreSQL database - database # Stats about the background writer process's activity - bgwriter # Stats about every PostgreSQL process - activity # Stats about every statement executed in the server. It requires the # `pg_stats_statement` library to be configured in the server. #- statement period: 10s # The host must be passed as PostgreSQL URL. Example: # postgres://localhost:5432?sslmode=disable # The available parameters are documented here: # https://godoc.org/github.com/lib/pq#hdr-Connection_String_Parameters hosts: ["postgres://localhost:5432"] # Username to use when connecting to PostgreSQL. Empty by default. #username: user # Password to use when connecting to PostgreSQL. Empty by default. #password: pass
The following metricsets are available:
