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 page documents the MikroTik RouterOS Ping tool, which uses ICMP Echo messages to test host connectivity and measure round-trip delays. It explains parameters like TTL, interval, count, and supports both IPv4/IPv6 addresses and DNS names. MAC Ping is also briefly mentioned in the context of multicast discovery.
Traceroute
Traceroute displays the path a packet takes to reach a remote host by analyzing TTL values and ICMP 'Time Exceeded' messages, helping identify routing issues or bottlenecks in multi-hop networks.
Torch
MikroTik Torch is a real-time traffic monitoring tool that observes network flow through interfaces, allowing analysis of source/destination addresses, ports, protocols, MACs, VLAN IDs, and DSCP values for troubleshooting.
Packet Sniffer
Packet Sniffer is a MikroTik RouterOS tool for capturing and analyzing network packets to diagnose issues or detect security threats. It supports filtering by IP, MAC, port, protocol, and more, with options to save packets in PCAPNG format or stream them to a PC for analysis.
Bandwidth Test
The Bandwidth Test feature in MikroTik RouterOS allows measuring network throughput between routers using TCP or UDP protocols, with detailed explanations of their behavior and limitations. It includes configuration options for bandwidth servers such as port ranges, authentication, and session limits, along with examples of enabling the server without client authentication.
Speed Test
The Speed Test tool measures ping, jitter, and TCP/UDP throughput between MikroTik devices using configurable properties like address, connection count, password, test duration, and user credentials. It provides detailed performance metrics including CPU utilization during testing.
Flood Ping
The Flood Ping tool in RouterOS sends continuous ICMP echo requests to test network stability, measure packet loss, and analyze latency under heavy traffic conditions with real-time statistics on sent/received packets and round-trip times.
Interface stats and monitor-traffic
This page documents MikroTik RouterOS interface statistics and monitor-traffic tools for real-time monitoring of network utilization, hardware performance, packet rates, and bitrates across physical and virtual interfaces. It includes commands to view interface counters, Fast Path metrics, link stability, and troubleshoot bandwidth bottlenecks.
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 using multiple probe types including ICMP, TCP, HTTP, DNS, and simple pings. It allows custom scripts for state changes and supports VRFs and link-local IPv6 addresses, with configurable thresholds and interval settings.
Graphing
Graphing is a RouterOS tool for monitoring CPU, memory, disk usage, and interface/queue traffic over time through visual graphs accessible via web browser or menu. Configuration options include data collection frequency, storage settings, and access permissions for specific IP ranges.
SNMP
This page documents SNMP configuration in MikroTik RouterOS, covering enabling the service, general settings like contact info and trap configurations, community access rights for SNMPv1/2c/3, and warnings about timeouts when monitoring slow services or OIDs.
Health
This page documents MikroTik RouterOS hardware health monitoring features, detailing metrics like temperature, voltage, fan speed, and CPU status for supported devices. It includes CLI examples, warnings about device limitations, and fan control parameters based on PoE-out load or temperature thresholds.
Resource
The Resource menu in RouterOS provides overview of system statistics including uptime, memory, disk usage, and hardware details like CPU model and frequency. It also offers submenus for detailed per-CPU usage, IRQ, and disk statistics.
Profiler
The Profiler tool in RouterOS displays CPU usage for each process, helping identify resource-intensive processes. It supports per-core monitoring and classifies CPU usage by process type for efficient debugging.
IP Scan
The IP Scan tool in RouterOS scans networks for active devices, collecting IP addresses, MAC addresses, response times, DNS names, SNMP strings, and NET-BIOS names. It can scan by IPv4 prefix or interface listening, with warnings against conflicting settings.
Detect Internet
Detect Internet is a RouterOS tool that categorizes monitored interfaces into states like Internet, WAN, LAN, and unknown, with warnings about DHCP client installation and state transitions based on link status and cloud reachability.
Dynamic DNS
Dynamic DNS Update Tool enables secure updates to domain name records for dynamic IP addresses using RFC-compliant algorithms, supporting only hmac-md5. It requires BIND DNS server and works with specified properties like IP, DNS server, key, and TTL.
Watchdog
The Watchdog page in RouterOS configuration allows setting up system reboots triggered by unresponsive IP addresses or software lockups, with options for ping monitoring and automatic support output file generation via email.
