NTP-PROXY-MIB

Description: University of Delaware MIB for monitoring and controlling multiple NTP servers through a single SNMP proxy agent on any NTP-capable host

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

NTP-PROXY-MIB is a University of Delaware standards-track MIB that lets a single SNMP agent act as a proxy for monitoring and controlling multiple NTP (Network Time Protocol) servers on other hosts, rather than modeling the local system's own clock. It defines a control table listing each remote NTP server's IP address and control status, plus a system-status table reporting each remote server's leap indicator, stratum, precision, root delay, root dispersion, and reference identifier, the standard NTP association-quality metrics. Its monitoring role is fundamentally software/service status for time synchronization: stratum and root-dispersion/delay values reveal how accurate and well-synchronized each proxied NTP server is, and a high stratum or large root dispersion signals a server that has lost a good upstream time reference. This proxy design lets one management station substitute this MIB for needing SNMP agents directly on every NTP server, though it depends conceptually on the base NTP protocol and the related IETF NTP MIB for its stratum/leap/precision semantics. It is deployed in environments with many NTP servers, such as campus or carrier networks, where centralizing NTP health monitoring through one proxy agent is more practical than instrumenting every server, and administrators consult the NTP-PROXY-MIB reference to identify the exact objects to poll for each proxied host.

A monitoring station polls ntpProxyServerSystemTable, indexed by ntpProxyServerIPAddr, to read ntpProxyServerSysStratum and ntpProxyServerSysRootDispersion for each proxied server, and checks ntpProxyControlStatus in ntpProxyControlTable to confirm the proxy is actively tracking that server; a server whose sysStratum jumps upward or whose sysLeap indicates an alarm condition signals it has lost synchronization to its reference clock.

Provides centralized monitoring and control of multiple NTP servers through a proxy agent, enabling remote management of distributed time synchronization.
