Cisco Configurations Changes Logger

This tool is composed of three tools working together to accomplish one goal, which is to post configurations changes on a Webex Channel

Components

1. Syslog-NG # OpenSource tool to receive syslogs and forward them to other destinations.
2. Conf_bk # Tool creates linux cron jobs to backup the device configurations and saves them locally on the server.
3. Logger # The tool that listens for incoming messages containing the message "Configured" and then triggers a worker to check what changed.

The tool takes advantage of the syslog that Cisco network devices send when a config change is done. Below is an example of the syslog that a Cisco IOS-XE device will send when a user goes into configure terminal mode.

*Apr 12 17:02:38.407: %SYS-5-CONFIG_I: Configured from console by console

When the Cisco device sends this logs to the server running this tool it will trigger a python worker to go and check the configurations and comparate it with the archive it has on file, afterwards it will do a post to Webex Space as the one below.
