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.

response received from server).
Update the `up` metric to return `0` if the socket connection fails.

Update the docker container to support mounting the fail2ban server socket
and pointing the exporter at it. This allows the exporter to interact with
the socket from within the container.
The entire `/var/run` folder is mounted instead of just the socket file to
correctly handle fail2ban restarts (where the file will be deleted).

Add new metric to track the total number of jails configured in fail2ban.
Add new metrics for the current and total number of filter failures for
each jail, as well as the current/total number of banned IPs per jail.
The new metrics are collected by sending the `status [jail]` command to the
fail2ban server and parsing the response data.

Hector e5714b7485 fix: read socket response data in chunks
Read the response data from the socket in chunks to prevent errors when
processing large payloads. The initial implementation solved large payloads
by just defining a very large buffer, but this is not a solution. The new
code reads the socket data in a loop until a terminator is found and
appends all the data into a single byte array.
Reduce the buffer size to `1024` bytes.

Add support for connecting the exporter directly to the fail2ban server's
socket to send requests and receive data. The path to the socket file is
optional and specified on startup.
Export a new metric based on the response of the `ping` command sent to the
fail2ban server. The metric is set to 1 if the server responds with `pong`
and 0 in any other case. This metric is only shown if the path to the
socket file was provided on startup.

Hector 526b1c7272 fix: update banned metrics to exclude expired bans
Update the database query counting the number of banned IPs to filter out
any bans that have already expired. An expired ban is defined as a ban
where the "time of ban" plus the "duration of ban" is less than the
current time.
This is necessary because bans that have expired are not automatically
removed from the database and will cause metrics to diverge from the counts
reported by `fail2ban-client`.

before the `up` metric does not throw an error.

Update the Makefile to include a new command to build the tool for docker

## 4. Building from source
Building from source has the following dependencies:
The simplest way to build the project is to run the `build/snapshot` make command.
This will use `goreleaser` to build out binaries and archives for the project.
Binaries are stored in the `dist/` folder.
- Go v1.20
- Make
From there, simply run `make build`
This will download the necessary dependencies and build a `fail2ban_exporter` binary in the root of the project.
Alternatively, `go mod download` and `go build` can be used from the `src/` folder to build out the project.
This will download dependencies and build the project.

1. Mount the folder with the metrics files
2. Set the `F2B_COLLECTOR_TEXT_PATH` environment variable
