An SNMP application is human-facing software, usually with a GUI, for monitoring and managing network devices through SNMP. It runs on the NMS alongside the SNMP manager; managed devices instead run an SNMP agent and maintain a MIB. section 6.1.2
An SNMP application supports these operational tasks:
- Periodically issue Get messages to read variables such as interface traffic, CPU and memory utilization, temperature, and power-supply health. section 6.1.2
- Use Set messages to modify MIB variables, initiate reboots, or back up configuration files. section 6.4
- Display notifications such as interface-down events and translate complex OIDs into descriptive names; vendor MIB files may be imported for proprietary OIDs. section 6.4
PRTG monitoring
PRTG Network Monitor can send SNMP Get messages every 60 seconds to devices on a network and display current monitored values through its GUI. section 6.1.2
Figure 6.4 The components of the NMS’s and managed devices’ SNMP entities. The NMS’s SNMP entity consists of the SNMP manager and SNMP application(s). The managed devices’ SNMP entities consist of the SNMP agent and the MIB.
Shows the NMS relationship: an SNMP manager and application reside on the NMS, while agents and MIBs reside on managed devices. section 6.1.2
