SNMP Monitoring and Management
 | Simple Network Management Protocol (SNMP) is a UDP-based network protocol, widely used to monitor and control network-attached devices, services and applications. |
SNMP is defined in a series of Internet Engineering Task Force (IETF) standards, covering not only the protocol itself, but also the Management Information Base (MIB) specification language (SMI and its successor SMIv2), a series of standard MIB definitions, and even the architecture of agent implementations.
SNMP overview and basic concepts are introduced in SNMP Basics section.
In Iotellect Network Manager SNMP support is provided by Network Host device driver. The driver provides:
- SNMP read and write operations
- SNMP-compliant device monitoring by:
- polling (periodical reading of full of partial management information available via SNMP)
- receiving and processing SNMP traps
- managing standard and custom SNMP devices
- caching management information on the server
- storing management information in database
- managing monitoring options:
- synchronization periods
- polling strategies: all OIDs, OIDs recognized by MIB directory, or the important ones only
- running automatic actions in response to SNMP traps
- MIB management, including:
- a set of standard MIBs
- tools for adding and configuring usage of custom MIBs
SNMP is used in network discovery:
- to find seed routers and get network topology information
- to discover SNMP-compliant devices
- to get some of their properties
Various practical aspects and details of SNMP utilization in Iotellect Network Manager are covered in Using SNMP section.
