[[outputs.postgresql]]
|
|
## Specify connection address via the standard libpq connection string:
|
|
## host=... user=... password=... sslmode=... dbname=...
|
|
## Or a URL:
|
|
## postgres://[user[:password]]@localhost[/dbname]?sslmode=[disable|verify-ca|verify-full]
|
|
## See https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-CONNSTRING
|
|
##
|
|
## All connection parameters are optional. Environment vars are also supported.
|
|
## e.g. PGPASSWORD, PGHOST, PGUSER, PGDATABASE
|
|
## All supported vars can be found here:
|
|
## https://www.postgresql.org/docs/current/libpq-envars.html

|
|
## Non-standard parameters:
|
|
## pool_max_conns (default: 1) - Maximum size of connection pool for parallel (per-batch per-table) inserts.
|
|
## pool_min_conns (default: 0) - Minimum size of connection pool.
|
|
## pool_max_conn_lifetime (default: 0s) - Maximum age of a connection before closing.
|
|
## pool_max_conn_idle_time (default: 0s) - Maximum idle time of a connection before closing.
|
|
## pool_health_check_period (default: 0s) - Duration between health checks on idle connections.
|
|
# connection = ""
|
|
|
|
## Postgres schema to use.
|
|
# schema = "public"
|
|
|
|
## Store tags as foreign keys in the metrics table. Default is false.
|
|
# tags_as_foreign_keys = false
|
|
|
|
## Suffix to append to table name (measurement name) for the foreign tag table.
|
|
# tag_table_suffix = "_tag"
|
|
|
|
## Deny inserting metrics if the foreign tag can't be inserted.
|
|
# foreign_tag_constraint = false
|
|
|
|
## Store all tags as a JSONB object in a single 'tags' column.
|
|
# tags_as_jsonb = false
|
|
|
|
## Store all fields as a JSONB object in a single 'fields' column.
|

## Templated statements to execute when adding columns to a table.
|
|
## Set to an empty list to disable. Points containing tags for which there is no column will be skipped. Points
|
|
## containing fields for which there is no column will have the field omitted.

## The postgres data type to use for storing unsigned 64-bit integer values (Postgres does not have a native
|
|
## unsigned 64-bit integer type).
|
|
## The value can be one of:
|
|
## numeric - Uses the PostgreSQL "numeric" data type.
|
|
## uint8 - Requires pguint extension (https://github.com/petere/pguint)
|
|
# uint64_type = "numeric"
|
|
|
|
## When using pool_max_conns>1, and a temporary error occurs, the query is retried with an incremental backoff. This
|
|
## controls the maximum backoff duration.
|
|
# retry_max_backoff = "15s"
|
|
|
|
## Approximate number of tag IDs to store in in-memory cache (when using tags_as_foreign_keys).
|
|
## This is an optimization to skip inserting known tag IDs.
|
|
## Each entry consumes approximately 34 bytes of memory.
|
|
# tag_cache_size = 100000
|
|
|
|
## Enable & set the log level for the Postgres driver.
|
|
# log_level = "warn" # trace, debug, info, warn, error, none
