## 0.9.0 / 2021-03-01 First release under the Prometheus Community organisation. * [CHANGE] Update build to use standard Prometheus promu/Dockerfile * [ENHANCEMENT] Remove duplicate column in queries.yml #433 * [ENHANCEMENT] Add query for 'pg_replication_slots' #465 * [ENHANCEMENT] Allow a custom prefix for metric namespace #387 * [ENHANCEMENT] Improve PostgreSQL replication lag detection #395 * [ENHANCEMENT] Support connstring syntax when discovering databases #473 * [ENHANCEMENT] Detect SIReadLock locks in the pg_locks metric #421 * [BUGFIX] Fix pg_database_size_bytes metric in queries.yaml #357 * [BUGFIX] Don't ignore errors in parseUserQueries #362 * [BUGFIX] Fix queries.yaml for AWS RDS #370 * [BUGFIX] Recover when connection cannot be established at startup #415 * [BUGFIX] Don't retry if an error occurs #426 * [BUGFIX] Do not panic on incorrect env #457 ## 0.8.0 / 2019-11-25 * Add a build info metric (#323) * Re-add pg_stat_bgwriter metrics which were accidentally removed in the previous version. (resolves #336) * Export pg_stat_archiver metrics (#324) * Add support for 'DATA_SOURCE_URI_FILE' envvar. * Resolve #329 * Added new field "master" to queries.yaml. (credit to @sfalkon) - If "master" is true, query will be call only on once database in instance * Change queries.yaml for work with autoDiscoveryDatabases options (credit to @sfalkon) - added current database name to metrics because any database in cluster maybe have the same table names - added "master" field for query instance metrics. ## 0.7.0 / 2019-11-01 Introduces some more significant changes, hence the minor version bump in such a short time frame. * Rename pg_database_size to pg_database_size_bytes in queries.yml. * Add pg_stat_statements to sample queries.yml file. * Add support for optional namespace caching. (#319) * Fix some autodiscovery problems (#314) (resolves #308) * Yaml parsing refactor (#299) * Don't stop generating fingerprint while encountering value with "=" sign (#318) (may resolve problems with passwords and special characters). ## 0.6.0 / 2019-10-30 * Add SQL for grant connect (#303) * Expose pg_current_wal_lsn_bytes (#307) * [minor] fix landing page content-type (#305) * Updated lib/pg driver to 1.2.0 in order to support stronger SCRAM-SHA-256 authentication. This drops support for Go < 1.11 and PostgreSQL < 9.4. (#304) * Provide more helpful default values for tables that have never been vacuumed (#310) * Add retries to getServer() (#316) * Fix pg_up metric returns last calculated value without explicit resetting (#291) * Discover only databases that are not templates and allow connections (#297) * Add --exclude-databases option (#298) ## 0.5.1 / 2019-07-09 * Add application_name as a label for pg_stat_replication metrics (#285). ## 0.5.0 / 2019-07-03 It's been far too long since I've done a release and we have a lot of accumulated changes. * Docker image now runs as a non-root user named "postgres_exporter" * Add `--auto-discover-databases` option, which automatically discovers and scrapes all databases. * Add support for boolean data types as metrics * Replication lag is now expressed as a float and not truncated to an integer. * When default metrics are disabled, no version metrics are collected anymore either. * BUGFIX: Fix exporter panic when postgres server goes down. * Add support for collecting metrics from multiple servers. * PostgreSQL 11 is now supported in the integration tests. ## 0.4.7 / 2018-10-02 * Added a query for v9.1 pg_stat_activity. * Add `--constantLabels` flag to allow applying fixed constant labels to metrics. * queries.yml: dd pg_statio_user_tables. * Support 'B' suffix in units. ## 0.4.6 / 2018-04-15 * Fix issue #173 - 32 and 64mb unit sizes were not supported in pg_settings. ## 0.4.5 / 2018-02-27 * Add commandline flag to disable default metrics (thanks @hsun-cnnxty) ## 0.4.4 / 2018-03-21 * Bugfix for 0.4.3 which broke pg_up (it would always be 0). * pg_up is now refreshed based on database Ping() every scrape. * Re-release of 0.4.4 to fix version numbering. ## 0.4.2 / 2018-02-19 * Adds the following environment variables for overriding defaults: * `PG_EXPORTER_WEB_LISTEN_ADDRESS` * `PG_EXPORTER_WEB_TELEMETRY_PATH` * `PG_EXPORTER_EXTEND_QUERY_PATH` * Add Content-Type to HTTP landing page. * Fix Makefile to produce .exe binaries for Windows. ## 0.4.1 / 2017-11-30 * No code changes to v0.4.0 for the exporter. * First release switching to tar-file based distribution. * First release with Windows and Darwin cross-builds.\\ ## 0.4.0 / 2017-11-29 * Fix panic due to inconsistent label cardinality when using queries.yaml with queries which return extra columns. * Add metric for whether the user queries YAML file parsed correctly. This also includes the filename and SHA256 sum allowing tracking of updates. * Add pg_up metric to indicate whether the exporter was able to connect and Ping() the PG instance before a scrape. * Fix broken link in landing page for `/metrics` ## 0.3.0 / 2017-10-23 * Add support for PostgreSQL 10. ## 0.2.3 / 2017-09-07 * Add support for the 16kB unit when decoding pg_settings. (#101) ## 0.2.2 / 2017-08-04 * Fix DSN logging. The exporter previously never actually logged the DSN when database connections failed. This was also masking a logic error which could potentially lead to a crash when DSN was unparseable, though no actual crash could be produced in testing. ## 0.2.1 / 2017-06-07 * Ignore functions that cannot be executed during replication recovery (#52) * Add a `-version` flag finally. * Add confirmed_flush_lsn to pg_stat_replication. ## 0.2.0 / 2017-04-18 * Major change - use pg_settings to retrieve runtime variables. Adds >180 new metrics and descriptions (big thanks to Matt Bostock for this work). Removes the following metrics: ``` pg_runtime_variable_max_connections pg_runtime_variable_max_files_per_process pg_runtime_variable_max_function_args pg_runtime_variable_max_identifier_length pg_runtime_variable_max_index_keys pg_runtime_variable_max_locks_per_transaction pg_runtime_variable_max_pred_locks_per_transaction pg_runtime_variable_max_prepared_transactions pg_runtime_variable_max_standby_archive_delay_milliseconds pg_runtime_variable_max_standby_streaming_delay_milliseconds pg_runtime_variable_max_wal_senders ``` They are replaced by equivalent names under `pg_settings` with the exception of ``` pg_runtime_variable_max_standby_archive_delay_milliseconds pg_runtime_variable_max_standby_streaming_delay_milliseconds ``` which are replaced with ``` pg_settings_max_standby_archive_delay_seconds pg_settings_max_standby_streaming_delay_seconds ``` ## 0.1.3 / 2017-02-21 * Update the Go build to 1.7.5 to include a fix for NAT handling. * Fix passwords leaking in DB url error message on connection failure. ## 0.1.2 / 2017-02-07 * Use a connection pool of size 1 to reduce memory churn on target database. ## 0.1.1 / 2016-11-29 * Fix pg_stat_replication metrics not being collected due to semantic version filter problem. ## 0.1.0 / 2016-11-21 * Change default port to 9187. * Fix regressions with pg_stat_replication on older versions of Postgres. * Add pg_static metric to store version strings as labels. * Much more thorough testing structure. * Move to semantic versioning for releases and docker image publications. ## 0.0.1 / 2016-06-03 Initial release for publication.
