SNMP (Simple Network Management Protocol) exposes operational metrics of routers, switches, servers and printers through a tree of numeric identifiers called OIDs. This tool runs an snmpwalk from our cloud against any reachable SNMP agent and streams the results back.
Provide the host, the UDP port (161 by default), the SNMP version (v1, v2c or v3), the community string, and the OID to walk. Results come back in numeric form (-On) so you can copy-paste them into your NMS.
Frequent OIDs
1.3.6.1.2.1.1 — System: sysDescr, sysUpTime, sysName, sysLocation.
1.3.6.1.2.1.2.2.1 — Interfaces table: bandwidth, counters, status.
1.3.6.1.2.1.25 — Host resources: CPU, memory, running processes.
FAQ
What's a community string? A shared password for SNMP v1/v2c. Common defaults are public (read-only) and private (read-write). Change these before exposing a device to the internet.
v1 vs v2c vs v3? v1 is legacy; v2c adds 64-bit counters and better error handling but is still plaintext; v3 adds authentication and encryption and is the only version safe for untrusted networks.
Why am I getting no response? The device might not allow SNMP from our IP, the community string is wrong, or UDP 161 is blocked by a firewall.
