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.
Create a new `collector` folder to store the code for the different
collectors. Move the existing f2b and textfile collectors to this folder.
Minor refactors to the f2b collector to better match the code style of the
newer textfile collector.
Update the goreleaser config to remove windows builds. It doesn't make
sense to build binaries for windows because fail2ban does not provide any
binary for windows. If windows support is required, docker can be used.
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 request handler for the root URL (`/`) to render a simple HTML
page with a link to the metrics page. This follows the convention of other
metric exporters.
Update the exporter startup to add more log messages. The server address,
port, and metrics path are now logged on startup.
A "ready" log message is printed when the server is up and running.
Split out all the code to define exporter functions and collect data into
a new package. The new package is responsible for all exporter related
activity. This makes the code easier to read.
Split the code for collecting metrics from the database and from the socket
into different files to make the separation more obvious.
Add a new `f2b_version` metric that includes the version of the fail2ban
server and the exporter.
Add a new socket command to get back the fail2ban server version.
