This release changes support for multiple postgres servers to use the multi-target exporter pattern. This makes it much easier to monitor multiple PostgreSQL servers from a single exporter by passing the target via URL params. See the Multi-Target Support section of the README.

- 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.
Introduces some more significant changes, hence the minor version bump in such a short time frame.

- [minor] fix landing page content-type (#305)

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.
- 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.
- Fix issue #173 - 32 and 64mb unit sizes were not supported in pg_settings.
- Add commandline flag to disable default metrics (thanks @hsun-cnnxty)
- 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.
-
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.
- 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.\
- 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
- Add support for PostgreSQL 10.
- Add support for the 16kB unit when decoding pg_settings. (#101)
- 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.
- Ignore functions that cannot be executed during replication recovery (#52)
- Add a
-version
flag finally. - Add confirmed_flush_lsn to pg_stat_replication.
-
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 ofpg_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
- 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.
- Use a connection pool of size 1 to reduce memory churn on target database.
- Fix pg_stat_replication metrics not being collected due to semantic version filter problem.
- 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.
Initial release for publication.
