## dir-monitor-log
Directory monitoring for get metric to **file count, size and modify.** When the number of files is changed, a diff of changes is logging.
**Service path:** /etc/systemd/system/[dir-monitor-log.service](https://github.com/Lifailon/shell-metrics/blob/rsa/service/dir-monitor-log.service) \
**Script path:** /root/[dir-monitor-log.sh](https://github.com/Lifailon/shell-metrics/blob/rsa/scripts/dir-monitor-log.sh) \
Script variables: \
**path_mon** - target directory for monitoring (example: **/var/lib/jenkins**) \
**path_log** - path to log file (example: **/var/log/metrics/dir-monitor.log**)
**Example:**
```bash
root@devops-01:~# systemctl daemon-reload
root@devops-01:~# systemctl enable dir-monitor-log.service
root@devops-01:~# systemctl start dir-monitor-log.service
root@devops-01:~# touch /var/lib/jenkins/test /var/lib/jenkins/test2
