It's the backbone of network monitoring, but it's not the only thing that can or should be used. Microsoft for example does not recommend using SNMP for OS monitoring on security grounds. The more advanced monitoring software out there like NetCrunch 8 will use performance data from the OS itself, instead of relying on SNMP. Flow data like from NetFlow can also give you much deeper insight into your network traffic than SNMP can. Most simpler devices will rely on SNMP however, like your IP phones, printers, etc.
SNMP
SNMP is the most widely used protocol for network monitoring
The monitoring authority of SNMP (Simple Network Management Protocol) is the Internet Engineering Task Force (IETF). They oversee the development and standardization of protocols related to network management, including SNMP.
If the projector is SNMP enabled, any network monitoring software out there will be able to do it for you.
To use SNMP logs in Avid ISIS servers, you need to enable SNMP monitoring on the server. This will allow you to collect information such as system performance, errors, and alerts on network traffic. You can then use SNMP monitoring tools to analyze and track the data collected from the server's SNMP logs.
It sends an alert message to the management station when a threshold is reached.
Brocade Network Monitoring offers one-way SNMP trap forwarding and filtering, sensing predefined threats, remote troubleshooting, and real time and predictive capabilities for the network.

The Simple Network Management Protocol (SNMP) server is a network management tool that enables the monitoring and management of network devices, such as routers, switches, and servers. It collects and organizes information about device status, performance, and configuration through management information bases (MIBs). SNMP allows network administrators to query devices for real-time data, send alerts for specific events, and manage device settings remotely. This helps ensure network reliability, performance, and security.
An SNMP trap is a notification sent from a network device, such as a router or switch, to a management system indicating that a specific event or condition has occurred. Unlike SNMP polling, where the management system requests information, traps are unsolicited messages triggered by events like device failures, threshold breaches, or performance issues. This allows for real-time monitoring and quicker response times to potential problems in the network. Traps are part of the Simple Network Management Protocol (SNMP), which is widely used for managing networked devices.
Usually its done via SNMP. A device(s) within the network tracks the packets/bytes and this information can be retrieved by the core network via SNMP GET. There are also other devices that integrate AAA and a flow monitoring device to report more accurate information.
