NET-SNMP-SYSTEM-MIB

The NET-SNMP-AGENT-MIB provides the control and monitoring structures for the Net-SNMP daemon itself, exposing internal agent metrics such as configuration state, session statistics, and error counters. It enables administrators to manage the operational status and behavior of the Net-SNMP agent process rather than monitoring external hardware or network protocols.

NET-SNMP-TC defines the standardized textual conventions and enumerations required by Net-SNMP agents to encode specific data types, such as interface status, IP address formats, and counter values, ensuring consistent interpretation across diverse network management systems. These definitions serve as the foundational data structures for all Net-SNMP managed objects, enabling precise monitoring of device states, traffic statistics, and protocol parameters without requiring vendor-specific extensions.

The NET-SNMP-EXTEND-MIB enables the Net-SNMP agent to execute external scripts and return their output as SNMP objects, allowing administrators to monitor custom-defined metrics such as script exit codes, process status, or arbitrary system data not covered by standard MIBs.

The NET-SNMP-EXAMPLES-MIB provides a non-operational framework of dummy objects and counter types for validating Net-SNMP agent compilation, configuration, and data retrieval logic. It serves exclusively as a development and testing tool to verify SNMPv2c/v3 protocol interactions, rather than monitoring live hardware metrics or production services.

The DIRECTORY-MONITOR-MIB facilitates the monitoring of directory service instances, specifically tracking operational metrics such as server availability, replication status, and active connection counts for LDAP-based directory servers. It enables administrators to detect service degradation or failures within directory infrastructure by exposing real-time performance counters and state transitions.

The NET-SNMP-MIB module provides the foundational infrastructure for the Net-SNMP project, exposing internal agent state variables such as configuration status, cache statistics, and agent initialization parameters. It serves as the core management interface for monitoring the operational health and runtime metrics of the Net-SNMP daemon itself rather than external network hardware or third-party protocols.
