Log Files
System event monitoring facility allows to debug different problems using Logs. Log file is a text file created in the
server/router/host capturing different kind of activity on the device. This file is the primary data analysis source.
RouterOS is capable of logging various system events and status information. Logs can be saved in routers memory
(RAM), disk, file, sent by email or even sent to remote syslog server.
All messages stored in routers local memory can be printed from /log menu. Each entry contains time and date
when event occurred, topics that this message belongs to and message itself.

Torch (/tool torch)
Torch is realtime traffic monitoring tool that can be used to monitor the traffic flow through an interface.
You can monitor traffic classified by protocol name, source address, destination address, port. Torch shows the
protocols you have chosen and tx/rx data rate for each of them.
Example:
The following example monitor the traffic generated by the telnet protocol, which passes through the interface
ether1.
[admin@MikroTik] tool> torch ether1 port=telnet
SRC-PORT DST-PORT TX RX
1439 23 (telnet) 1.7kbps 368bps
[admin@MikroTik] tool>
To see what IP protocols are sent via ether1:
[admin@MikroTik] tool> torch ether1 protocol=any-ip
PRO.. TX RX
tcp 1.06kbps 608bps
udp 896bps 3.7kbps
