  data_collection:
    metrics_description: |
      Monitor Fail2ban performance for prime intrusion prevention operations. Monitor ban counts, jail statuses, and failed login attempts to ensure robust network security.
    method_description: |
      It collects metrics through reading the default log and configuration files of fail2ban.
  supported_platforms:
    include: []
    exclude: []
  multi_instance: true
  additional_permissions:
    description: |
      The `fail2ban.log` file must be readable by the user `netdata`.
        - change the file ownership and access permissions.
        - update `/etc/logrotate.d/fail2ban`` to persist the changes after rotating the log file.

      To change the file ownership and access permissions, execute the following:

      ```shell
      sudo chown root:netdata /var/log/fail2ban.log
      sudo chmod 640 /var/log/fail2ban.log
      ```

      To persist the changes after rotating the log file, add `create 640 root netdata` to the `/etc/logrotate.d/fail2ban`:

      ```shell
      /var/log/fail2ban.log {

          weekly
          rotate 4
          compress

          delaycompress
          missingok
          postrotate
              fail2ban-client flushlogs 1>/dev/null
          endscript

          # If fail2ban runs as non-root it still needs to have write access
          # to logfiles.
          # create 640 fail2ban adm
          create 640 root netdata
      }
      ```

        There are 2 sections:

        * Global variables
        * One or more JOBS that can define multiple different instances to monitor.

        The following options can be defined globally: priority, penalty, autodetection_retry, update_every, but can also be defined per JOB to override the global values.

        Additionally, the following collapsed table contains all the options that can be configured inside a JOB definition.

        Every configuration JOB starts with a `job_name` value which will appear in the dashboard, unless a `name` parameter is specified.
