Update the example grafana dashboard to add support for multiple
exporter instances. This includes updating panel queries and display
names.
The grafana version has been bumped to 9.1.8.
Add a new startup option to exit the exporter when an error occurs when connecting to the fail2ban socket file.
This option is set to "false" by default.
Rewrite the project README file to be more succinct and to the point. Add
new section on getting started quickly with either docker or the standalone
binary file.
Update CHANGELOG file with recent changes.
Replace existing CLI flags to make them more consistent and follow a more
standard format.
Remove CLI flags and environment variables that are no longer relevant.
Add short `-v` option for version flag.
Update README with new documentation.
BREAKING CHANGE: Replace `--socket` flag with `--collector.f2b.socket`.
BREAKING CHANGE: Merge `--port` flag and `--web.listen-address` into a single flag.
BREAKING CHANGE: Remove `--collector.textfile` flag, its value is now derived from `--collector.textfile.directory`.
BREAKING CHANGE: Remove `F2B_COLLECTOR_TEXT` and `F2B_WEB_PORT` environment variables.
Update the docker image to remove the `run.sh` script and instead run the
exporter directly. This keeps the docker image as simple as possible.
Update README file with extra info on how to collect textfile metrics in
a docker container.
BREAKING CHANGE: Using the textfile collector in docker now requires setting environment variables.
Replace CLI parsing functionality with the `kingpin` library to better
support configuring the tool with environment variables.
Add new environment variables to configure the tool.
BREAKING CHANGE: CLI params now require two dashes instead of one (e.g. `--socket`)
Add new CLI parameters to enable protecting the API endpoints with basic
auth authentication.
Wrap the server endpoints in a new auth middleware that protects it using
the provided basic auth credentials (if set).
Store the provided basic auth credentials as hashed values to prevent them
from being accidentally leaked.
Add unit tests to ensure the new functionality works as expected.
Update the sample Grafana dashboard to use a variable for the data
source. All panels have been updated to use the new variable. This makes
it easier to import the dashboard and have it work with different data
sources.
Add new -web.listen-address command line parameter, so that the
listening interface can be limited. This follows a similar style as
the official prometheus-node-exporter project.
Update project README with the new parameter.
Remove all database-based metrics from the metrics endpoint.
Remove all code related to pulling metrics from the fail2ban database.
Remove all configuration variables related to the fail2ban database.
The CLI parameter for the database path was not removed to avoid breaking
compatibility.
Update docker entrypoint to remove references to the fail2ban database.
Remove all references to the old database metrics from the README.
Add new metrics around basic jail configuration. The new metrics expose the
max retries, ban time, and find time for each jail.
Update project README with the new metrics.
Add support for collecting arbitrary metrics from a textfile as well as
metrics collected from fail2ban. This allows other data to be exported
along with the fail2ban metrics (e.g. instance metadata).
Update the docker image to allow mounting a folder with a collection of
metric files to be exported. Only files ending in `.prom` with be read.
Update project README with the new functionality.
Add a new metric to count the number of database errors that have been
found since startup. This complements the `up` metric to have better
visibility into occasional database errors.
Add a new prometheus metric to track which jails are currently enabled.
Add a new database query to read the jail name and enabled status from the
database.
Add new metric to readme file.
