To use IF statements, hence to be able to check if the user exists before - attempting creation, we need to switch to procedural SQL (PL/pgSQL) - instead of standard SQL. You need to monitor older PostgreSQL servers, you will have to create functionsĪnd views as a superuser, and assign permissions separately to those. Server versions >= 10 you can grant the pg_monitor or pg_read_all_stats built-in roles to the user. To be able to collect metrics from pg_stat* views as non-superuser in PostgreSQL Pg_database table, but do scrape from only if database is in include list. If you want to include only subset of databases, you can use option -include-databases. In addition, the option -exclude-databases adds the possibily to filter the result from the auto discovery to discard databases you do not need. Result a new set of DSN's is created for which the metrics are scraped. When true, SELECT datname FROM pg_database WHERE datallowconn = true AND datistemplate = false and datname != current_database() is run for all configured DSN's. To scrape metrics from all databases on a database server, the database DSN's can be dynamically discovered via the (so you must supply one, otherwise the exporter will return nothing but internal statuses and not your database). This removes all built-in metrics, and uses only metrics defined by queries in the queries.yaml file you supply Greenplum), you can disable the default metrics with the -disable-default-metricsįlag. To work with non-officially-supported postgres versions (e.g. Some examples are provided in queries.yaml. The -extend.query-path command-line argument specifies a YAML file containing additional queries to run. Rich self-documenting metrics for the exporter. strip())Īdjust the value of the resultant prometheus value type appropriately. This will build the docker image as prometheuscommunity/postgres_exporter:$, """. Promu crossbuild -p linux/amd64 -p linux/armv7 -p linux/amd64 -p linux/ppc64le auth_modules is a map of modules with the key being the identifier which can be used in the /probe endpoint.Ĭurrently only the userpass type is supported. This section defines preset authentication and connection parameters for use in the multi-target endpoint. It can be set using the -config.file command line flag and defaults to postgres_exporter.yml. The configuration file controls the behavior of the exporter. auth_modules for DSNs can be used with the /probe endpoint by specifying the ?auth_module=foo http parameter. To avoid putting sensitive information like username and password in the URL, preconfigured auth modules are supported via the auth_modules section of the config file. To use the multi-target functionality, send an http request to the endpoint /probe?target=foo:5432 where target is set to the DSN of the postgres instance to scrape metrics from. Using the milti-target funcationality of this exporter is optional and meant for users where it is impossible to install the exporter as a sidecar. This allows running a single instance of this exporter for multiple postgres targets. This exporter supports the multi-target pattern. This Feature is in beta and may require changes in future releases. Quay.io/prometheuscommunity/postgres-exporter Docker run -net=host -it -rm -e POSTGRES_PASSWORD=password postgres
