## v0.8.0
|
||||
|

- 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
|
||||

|
||||
|
||||
## v0.7.0
|
||||
|
||||
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.

||||

||||

|
||||
* Don't stop generating fingerprint while encountering value with "=" sign (#318)
|
||||

|
||||

|
||||
|
||||
## v0.5.0
|
||||
|
||||
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.
|
||||
|
||||
## v0.4.7
|
||||
|
||||
* 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.
|
||||
|
||||
## v0.4.6
|
||||
|
||||
* Fix issue #173 - 32 and 64mb unit sizes were not supported in pg_settings.
|
||||
|
||||
## v0.4.5
|
||||
|
||||
* Add commandline flag to disable default metrics (thanks @hsun-cnnxty)
|
||||
|
||||
## v0.4.4
|
||||
|
||||
* 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.
|
||||
|
||||
## v0.4.2
|
||||
|
||||
* 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.
|
||||
|
||||
## v0.4.1
|
||||
|
||||
* 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.\\
|
||||
|
||||
## v0.4.0
|
||||
|
||||
* 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`
|
||||
|
||||
## v0.3.0
|
||||
|
||||
* Add support for PostgreSQL 10.
|
||||
|
||||
## v0.2.3
|
||||
|
||||
* Add support for the 16kB unit when decoding pg_settings. (#101)
|
||||
|
||||
## v0.2.2
|
||||
|
||||
* 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.
|
||||
|
||||
## v0.2.1
|
||||
|
||||
* Ignore functions that cannot be executed during replication recovery (#52)
|
||||
* Add a `-version` flag finally.
|
||||
* Add confirmed_flush_lsn to pg_stat_replication.
|
||||
|
||||
## v0.2.0
|
||||
|
||||
* 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
|
||||
```
|
||||
|
||||

|
||||
|
||||
* Update the Go build to 1.7.5 to include a fix for NAT handling.
|
||||

|
||||
|
||||
## v0.1.2
|
||||
|
||||

|
||||
|
||||
## v0.1.1
|
||||
|
||||
* Fix pg_stat_replication metrics not being collected due to semantic version
|
||||
filter problem.
|
||||
|
||||
## v0.1.0
|
||||
|
||||
* Change default port to 9187.
