Diagnostics and Monitoring
This section covers RouterOS diagnostic and monitoring tools. Use it to inspect traffic, test connectivity, collect logs, monitor resources, analyze flow data, and investigate network or device issues.
Ping
The RouterOS ping tool: check that a host or the internet is reachable, read the status of each reply, find the path MTU, ping from a chosen address, interface or VRF, reach hosts that block ICMP with ARP and ND ping, discover IPv6 hosts, ping MAC addresses and use ping in scripts.
Traceroute
The RouterOS traceroute tool: list the routers on the path to a host, read the per-hop loss and round-trip statistics, find where a path breaks, loops or is filtered, and trace from a VRF or a chosen source address.
Torch
Torch shows the traffic that passes one interface right now, grouped into flows by address, protocol, port and DSCP, with the rate in each direction. Find the host that uses the bandwidth, watch one protocol or port, check VLAN tags and DSCP marking, see traffic that the firewall drops, and see which CPU handles it.
Packet Sniffer
The RouterOS packet sniffer: capture packets on the router, filter them, watch them live in the console, save them to a pcapng file for Wireshark or stream them to a PC over TZSP, and know what the sniffer cannot see.
Bandwidth test
The bandwidth test measures TCP or UDP throughput between two MikroTik routers: the client in /tool/bandwidth-test sends to or receives from the bandwidth test server of the other router. It covers prerequisites, tests at a fixed or the maximum rate, reading the results and securing the server.
Speed Test
Speed test measures ping, jitter and TCP and UDP throughput in both directions between two MikroTik routers in one run, through the bandwidth test server of the remote router.
Flood Ping
Flood ping sends a series of up to 1000 ICMP echo requests in one run and shows only the totals: requests sent, replies received and the shortest, average and longest round-trip time. It needs the traffic-gen device-mode feature.
Interface stats and monitor-traffic
Interface statistics and real-time traffic monitoring on MikroTik RouterOS: print interface counters (stats, stats-detail), watch per-second rates with monitor-traffic, and run script triggers when a rate crosses a threshold with /tool/traffic-monitor.
Traffic Generator
Traffic Generator is a MikroTik RouterOS tool for evaluating device performance by generating and sending raw packets over ports, collecting latency, jitter, throughput, and packet loss data. It supports advanced features like OOO detection and PCAP injection, with configurable properties and commands for quick setup.
Netwatch
Netwatch monitors network hosts with simple, ICMP, TCP, HTTP, HTTPS or DNS probes at configurable intervals and thresholds, and runs scripts when a host goes up or down.
Graphing
RouterOS graphing: record CPU, memory and disk usage and interface and simple queue traffic over time, view the daily, weekly, monthly and yearly graphs on the router's /graphs/ web page or in WinBox, choose who can see them, and keep them across reboots.
SNMP
Enable the SNMP agent, control which communities can read the router and what they can change, and receive traps. Covers the community access model, SNMPv3 security, finding OIDs, traps, and writing router settings (identity, scripts, reboot) over SNMP.
Health
This page documents MikroTik RouterOS hardware health monitoring, covering temperature, voltage, current, power supply and power consumption readings, fan control settings, SNMP OIDs, and REST API and script examples for alerts.
Resource
The /system/resource menu shows the router's identity and usage: uptime, RouterOS version, memory, disk/NAND, CPU model and load; submenus break load down per core (cpu), per interrupt (irq), steer packet handling between cores (irq/rps), list PCI/USB/SCSI hardware (hardware) and allow USB power control.
Profiler
The Profiler tool shows CPU usage for each RouterOS process classifier, summed or per core, to identify which process consumes CPU resources.
IP Scan
IP scan finds the devices on a network: scan an address range to list the hosts with their MAC addresses, response times, DNS and SNMP names, or listen on an interface to see the addresses that devices use, including devices with an unknown static address.
Detect Internet
Detect Internet gives each watched interface a state (lan, wan, internet and others) from its link, its routes and MikroTik cloud reachability, and keeps interface lists up to date with the result.
DNS update
The DNS update tool sends an RFC 2136 dynamic update, signed with a TSIG hmac-md5 key, to the authoritative DNS server of a zone to point a name at an IPv4 address.
Watchdog
Watchdog reboots the router when the system stops responding or when one IP address stops answering pings, and writes a support output file after a software failure.
