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.
