-# Fail2Ban Prometheus Exporter
+# prometheus-fail2ban-exporter
 
-Go tool to collect and export metrics on Fail2Ban
+This is a fork of Hector's fail2ban [exporter](https://gitlab.com/hectorjsmith/fail2ban-prometheus-exporter). This fork
+contains some changes to get the application running in a kubernetes cluster.
 
 ## Table of Contents
-1. Introduction
-2. Running the Exporter
-3. Running in Docker
-4. Metrics
 
-## 1. Introduction
+1. Quick Start
-The exporter can collect metrics from 2 locations: the fail2ban server socket and the fail2ban server database.
+2. Metrics
+3. Configuration
+4. Building from source
+5. Textfile metrics
 
-Once the exporter is running, metrics are available at `localhost:9191/metrics`.
+## 1. Quick Start
 
-(The default port is `9191` but can be modified with the `-port` flag)
+The exporter can be run as a standalone binary or a docker container.
 
-The exporter communicates with the fail2ban server over its socket.
+### 1.1. Standalone
-This allows the data collected by the exporter to always align with the output of the `fail2ban-client`.
 
-The default location of the socket is: `/var/run/fail2ban/fail2ban.sock`
+The following command will start collecting metrics from the `/var/run/fail2ban/fail2ban.sock` file and expose them on
+port `9191`.
 
-## 2. Running the Exporter
+```bash
+$ fail2ban_exporter --collector.f2b.socket=/var/run/fail2ban/fail2ban.sock --web.listen-address=":9191"
 
-The exporter is compiled and released as a single binary.
+2022/02/20 09:54:06 fail2ban exporter version 0.8.1
-This makes it very easy to run in any environment.
+2022/02/20 09:54:06 starting server at :9191
-No additional runtime dependencies are required.
+2022/02/20 09:54:06 reading metrics from fail2ban socket: /var/run/fail2ban/fail2ban.sock
-
+2022/02/20 09:54:06 metrics available at '/metrics'
-Compiled binaries for various platforms are provided in each release.
+2022/02/20 09:54:06 ready
-See the [releases page](https://gitlab.com/hectorjsmith/fail2ban-prometheus-exporter/-/releases) for more information.
-
-**Usage**
-```
-$ fail2ban-prometheus-exporter -h
-
-  -port int
-        port to use for the metrics server (default 9191)
-  -socket string
-        path to the fail2ban server socket
-  -version
-        show version info and exit
-  -collector.textfile
-        enable the textfile collector
-  -collector.textfile.directory string
-        directory to read text files with metrics from
 ```
 
-**Example**
+Binary files for each release can be found on the
+[releases](https://gitlab.com/hectorjsmith/fail2ban-prometheus-exporter/-/releases) page.
 
-```
+There is also an [example systemd service file](/_examples/systemd/fail2ban_exporter.service) included in the
-fail2ban-prometheus-exporter -socket /var/run/fail2ban/fail2ban.sock -port 9191
+repository. This is a starting point to run the exporter as a service.
-```
 
-Note that the exporter will need read access to the fail2ban socket.
+### 1.2. Docker
 
-### 2.1. Compile from Source
+#### Docker run
 
-The code can be compiled from source by running `go build` inside the `src/` folder.
+```bash
-Go version `1.15` or greater is required.
+$ docker run -d \
-
-Run `go mod download` to download all necessary dependencies before running the build.
-
-## 3. Running in Docker
-
-An official docker image is available on the Gitlab container registry.
-Use it by pulling the following image:
-
-```
-registry.gitlab.com/hectorjsmith/fail2ban-prometheus-exporter:latest
-```
-
-Use the `:latest` tag to get the most up to date code (less stable) or use one of the version tagged images to use a specific release.
-See the [registry page](https://gitlab.com/hectorjsmith/fail2ban-prometheus-exporter/container_registry) for all available tags.
-
-### 3.1. Volumes
-
-The docker image is designed to run by mounting the fail2ban run folder.
-The run folder should be mounted in the container at: `/var/run/fail2ban`.
-
-The folder can be mounted with read-only (`ro`) permissions.
-
-**NOTE:** While it is possible to mount the `fail2ban.sock` file directly, it is recommended to mount the parent folder instead.
-The `.sock` file is deleted by fail2ban on shutdown and re-created on startup and this causes problems for the docker mount.
-See [this reply](https://gitlab.com/hectorjsmith/fail2ban-prometheus-exporter/-/issues/11#note_665003499) for more details.
-
-### 3.2. Docker run
-
-Use the following command to run the exporter as a docker container.
-
-```
-docker run -d \
     --name "fail2ban-exporter" \
     -v /var/run/fail2ban:/var/run/fail2ban:ro \
     -p "9191:9191" \
     registry.gitlab.com/hectorjsmith/fail2ban-prometheus-exporter:latest
 ```
 
-### 3.3. Docker compose
+#### Docker compose
 
-The following is a simple docker-compose file to run the exporter.
+```yaml
-
-```

+for more details.
 
-**Note on Fail2Ban Jails**
+## 2. Metrics
 
-fail2ban can be configured to process different log files and use different rules for each one.
+The exporter exposes the following metrics:
-These separate configurations are referred to as *jails*.
 
-For example, fail2ban can be configured to watch the system logs for failed SSH connections and Nextcloud logs for failed logins.
+*All metric names are prefixed with `f2b_`*
-In this configuration, there will be two jails - one for IPs banned from the SSH logs, and one for IPs banned from the Nextcloud logs.
 
-This tool exports several metrics *per jail*, meaning that it is possible to track how many IPs are being banned in each jail as well as the overall total.
+| Metric                       | Description                                                                        | Example                                             |
-This can be useful to track what services are seeing more failed logins.

-### 4.2. Textfile Metrics
+### 2.1. Grafana
+
+The metrics exported by this tool are compatible with Prometheus and Grafana. A sample grafana dashboard can be found in
+the [grafana.json](/_examples/grafana/dashboard.json) file. Just import the contents of this file into a new Grafana
+dashboard to get started.
+
+The dashboard supports displaying data from multiple exporters. Use the `instance` dashboard variable to select which
+ones to display.
+
+*(Sample dashboard is compatible with Grafana `9.1.8` and above)*
+
+## 3. Configuration
+
+The exporter is configured with CLI flags and environment variables. There are no configuration files.
+
+### CLI flags
+
+```text
+🚀 Collect prometheus metrics from a running Fail2Ban instance
+
+Flags:
+  -h, --help                          Show context-sensitive help.
+  -v, --version                       Show version info and exit
+      --dry-run                       Attempt to connect to the fail2ban socket then exit
+                                      before starting the server

+                                      ($F2B_WEB_LISTEN_ADDRESS)
+      --collector.f2b.socket="/var/run/fail2ban/fail2ban.sock"
+                                      Path to the fail2ban server socket
+                                      ($F2B_COLLECTOR_SOCKET)
+      --collector.f2b.exit-on-socket-connection-error
+                                      When set to true the exporter will immediately
+                                      exit on a fail2ban socket connection error
+                                      ($F2B_EXIT_ON_SOCKET_CONN_ERROR)
+      --collector.textfile.directory=STRING
+                                      Directory to read text files with metrics from
+                                      ($F2B_COLLECTOR_TEXT_PATH)
+      --web.basic-auth.username=STRING
+                                      Username to use to protect endpoints with basic auth
+                                      ($F2B_WEB_BASICAUTH_USER)
+      --web.basic-auth.password=STRING
+                                      Password to use to protect endpoints with basic auth
+                                      ($F2B_WEB_BASICAUTH_PASS)
+```
+
+### Environment variables
+
+Each environment variable corresponds to a CLI flag. If both are specified, the CLI flag takes precedence.
+
+| Environment variable            | Corresponding CLI flag                            |
+|---------------------------------|---------------------------------------------------|
+| `F2B_COLLECTOR_SOCKET`          | `--collector.f2b.socket`                          |
+| `F2B_COLLECTOR_TEXT_PATH`       | `--collector.textfile.directory`                  |
+| `F2B_WEB_LISTEN_ADDRESS`        | `--web.listen-address`                            |
+| `F2B_WEB_BASICAUTH_USER`        | `--web.basic-auth.username`                       |
+| `F2B_WEB_BASICAUTH_PASS`        | `--web.basic-auth.password`                       |
+| `F2B_EXIT_ON_SOCKET_CONN_ERROR` | `--collector.f2b.exit-on-socket-connection-error` |
+
+## 4. Building from source
+
+Building from source has the following dependencies:
+
+- 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.
+
+## 5. Textfile metrics
 
 For more flexibility the exporter also allows exporting metrics collected from a text file.
 
-To enable textfile metrics:
+To enable textfile metrics provide the directory to read files from with the `--collector.textfile.directory` flag.
-1. Enable the collector with `-collector.textfile=true`
-2. Provide the directory to read files from with the `-collector.textfile.directory` flag
 
-Metrics collected from these files will be exposed directly alongside the other metrics without any additional processing.
+Metrics collected from these files will be exposed directly alongside the other metrics without any additional
-This means that it is the responsibility of the file creator to ensure the format is correct.
+processing. This means that it is the responsibility of the file creator to ensure the format is correct.
 
 By exporting textfile metrics an extra metric is also exported with an error count for each file:
 
-```
+```text
 # HELP textfile_error Checks for errors while reading text files
 # TYPE textfile_error gauge
 textfile_error{path="file.prom"} 0
 ```
 
 **NOTE:** Any file not ending with `.prom` will be ignored.
+
+### Running in Docker
+
+To collect textfile metrics inside a docker container, a couple of things need to be done:
+
+1. Mount the folder with the metrics files
+2. Set the `F2B_COLLECTOR_TEXT_PATH` environment variable
+
+*For example:*
+
+```bash
+$ docker run -d \
+    --name "fail2ban-exporter" \
+    -v /var/run/fail2ban:/var/run/fail2ban:ro \
+    -v /path/to/metrics:/app/metrics/:ro \
+    -e F2B_COLLECTOR_TEXT_PATH=/app/metrics \
+    -p "9191:9191" \
+    registry.gitlab.com/hectorjsmith/fail2ban-prometheus-exporter:latest
+```

+- It expects the binary file to be installed at `/usr/sbin/fail2ban_exporter`.
+- It expects a user named `fail2ban_exporter` to exist. This user should not have a shell or any special privileges
+  aside from read-access to the fail2ban socket file.
+
+The `ExecStart` line can be modified to add any custom CLI flags.
