What can be monitored with SNMP?
SNMP can comprehensively monitor not only the network elements like routers and switches, but can also be used to monitor network servers. Details like server hardware description, physical location, IP address, available disk space and server uptime can be monitored through SNMP.
Can SNMP monitor services?
SNMP is supported on an impressive array of hardware, including wireless access points, routers, switches, gateways, scanners, printers, and even IoT devices. Beyond SNMP hardware monitoring, the protocol can be used to monitor services such as DHCP.

Cluster heartbeats— Each WebLogic Server instance in a cluster uses multicast to broadcast regular “heartbeat” messages that advertise its availability. By monitoring heartbeat messages, server instances in a cluster determine when a server instance has failed.
How does SNMP monitoring work?
SNMP monitoring can be used to collect information from your entire fleet of network devices. SNMP relies on a client-server application model, where a software server component (the SNMP Manager) collects information by querying a software client component (the SNMP Agent), which runs on a network device.
What data can you get from SNMP?
Thanks to SNMP the monitoring software is able to retrieve the data from almost all devices – such as the CPU load of the firewall, the toner level of the network printer, the temperature in the server room, or all information on the interfaces of a switch.
Which of the SNMP tool is used to monitor network traffic?
OpManager monitors interfaces using SNMP and provides a single customizable dashboard to view and analyze bandwidth performance and network traffic for your IT network.
What is SNMP walk?
SNMP walk is an application that runs multiple GETNEXT requests automatically. The SNMP walk command allows users to extract useful information without entering the unique commands for each OID or node. SNMP walk simplifies the extraction of information from MIB as it is issued to the root-node of the sub-tree.
Which API is used by WebLogic to manage and monitor its resources?
Java Transaction API (JTA) is built into WebLogic to manage transactions.
What is the purpose of SNMP?
Although the original purpose of the Simple Network Management Protocol (SNMP) was to let network administrators remotely manage an Internet system, the design of SNMP lets network administrators manage applications and systems. SNMP provides the following capabilities: Hides the underlying system network.
