+# Changelog
+
+## 0.5.0
+
+### Improvements
+* Added home page with link to metrics.
+* Added new fields to output parsed from passenger status command.
+* Removed mentions of nginx as this exporter can support other integration modes.
+
+### Breaking Changes
+* Changed metrics prefix from `passenger_nginx` to `passenger`. This affects _all_ passenger metrics.
+* Renamed metrics:
+ * Changed `passenger_top_level_queue` to `passenger_top_level_request_queue`.
+ * Changed `passenger_app_queue` to `passenger_app_request_queue`.
+* Changed unit of passenger command timeout duration to seconds.
+* Removed deprecated `code_revision` field from output parsed from passenger status command.

-************************
-passenger_exporter_nginx
-------------------------
-
-This is a Prometheus exporter for passenger with nginx integration.
-
-https://www.phusionpassenger.com/
-
-*********************
-Building the Exporter
----------------------
-
-The default Makefile target creates a statically linked binary for Linux.
-
-A Dockerfile and Makefile target are also supplied:
-
-make build-docker
-
-********************
-Running the Exporter
---------------------
-
-Usage of passenger_exporter_nginx:
- -log.format value
- If set use a syslog logger or JSON logging.
- Example: logger:syslog?appname=bob&local=7 or logger:stdout?json=true.
- Defaults to stderr.
- -log.level value
- Only log messages with the given severity or above.
- Valid levels: [debug, info, warn, error, fatal]. (default info)
- -passenger.command string
- Passenger command for querying passenger status.
- (default "passenger-status --show=xml")
- -passenger.pid-file string
- Optional path to a file containing the passenger/nginx PID for additional metrics.
- -passenger.command.timeout duration
- Timeout for passenger.command. (default 500ms)
- -web.listen-address string
- Address to listen on for web interface and telemetry. (default ":9149")
- -web.telemetry-path string
- Path under which to expose metrics. (default "/metrics")
-
-To run the Docker image:
-
-docker run -p 9106:9106 -v $PATH_TO_PASSENGER_STATUS:/bin \
- passenger_exporter_nginx:latest /passenger_exporter_nginx
-
-Notes for running the Docker container:
-
-- You must mount the passenger-status binary within the container to
- have access.
-- You must expose the -web.listen-address port on the container to be scraped.
-
-**********
-Collectors
-----------
-
-An example of the metrics exported can be seen in testdata/scrape_output.txt
-
-*************
-Running Tests
--------------
-
-Tests can be run with:
-
-go test .
-
-Additionally, the testdata/scrape_output.txt can be regenerated by passing the
---golden flag:
-
-go test -v . --golden
