SNMP is one of the widely accepted protocols to manage and monitor network elements. SNMP supports read and write access which enables control over a device.

SNMP include a software agent on each monitored device. Most of the network elements come bundled with a SNMP agent. Allowing SNMP read-write access gives one complete control over the device. Using SNMP, one can replace the entire configuration of the device. You can read about SNMP in here.

And But WMI. It is a protocol use for monitoring Microsoft windows based servers and applications and does not monitor network devices or non-Microsoft servers. CIM is a model which represents the components of the operating system OS. You can read about WMI in here. Source: en. Configuring thresholds helps in proactively monitoring the resources and services running on servers and network devices.

Multi-level threshold can assist in classifying and breaking down any fault encountered. Utilizing thresholds, alerts can be raised before the device goes down or reaches critical condition. When levels reach those thresholds, the network monitoring system triggers an alarm and initiates network fault management processes. There is a concept here called trigger.

Triggers are events that will generate alarms in the system. An event might refer to a deviation from mean value of a parameter, a crossed threshold parameter value, a change in the state of a node. The process of network monitoring and management is simplified and automated with the help of network monitoring software and network monitor tools. A network performance monitor is essential to tackle network bottlenecks and performance woes which might have a negative impact on network performance.

The network monitoring section of the tool is able to automatically discover all devices attached to the network. Site24x7 compiles an equipment inventory from the results of that search and then draws up network topology maps automatically.

The inventory and maps all get updated automatically whenever equipment gets added, moved, or removed. This system is built into all network devices. It just needs an SNMP manager to request status information from the agent software that is loaded onto every switch and router by their manufacturers.

Site24x7 fulfills that SNMP manager. SNMP includes a procedure that allows device agents to send a notification to the manager when it discovers a critical condition on the device that it is monitoring. This message gets converted into a warning or an alert by the Site24x7 dashboard, depending on the severity rating marked on the message from the agent. Site24x7 monitors switches, routers, firewall appliances, power supplies, load balancers, wireless networks, cloud services, and WAN connections.

The monitor focuses on connected hardware. A wider view of the Site24x7 package shows that the system also monitors other hardware, such as endpoints and servers. It also tracks the performance of applications. A user behavior module in the package is of particular use to businesses that run websites.

It includes real user monitoring to analyze typical buyer journeys and also synthetic web transaction monitoring , which simulates access to a website. Site24x7 offers a free network monitoring service. However, this is just a straightforward Ping-based uptime monitor for up to 50 URLs or servers.
