## What is real-time network monitoring?

Real-time network monitoring is the continuous, instant tracking of network health to detect issues the moment they surface. Unlike traditional tools that report with a delay, real-time monitoring provides live visibility into devices, traffic, and performance. This allows IT teams to identify outages, security anomalies, or bandwidth spikes immediately, preventing impact on business-critical services.

## Shift from firefighting to proactive monitoring with OpManager

OpManager gives you the real-time visibility you need to keep your network healthy, your devices responsive, and your business running without interruptions.

### Stay ahead of performance issues in real time

- [With OpManager's high-frequency polling watching CPU, memory](https://www.manageengine.com/network-monitoring/cpu-memory-disk.html?rtm), uptime, and other metrics in real time, you’ll spot performance spikes instantly.
- Real-time metrics give you early warnings about performance dips, helping applications stay steady across on-prem, cloud, and hybrid setups.
- OpManager tracks installed software and active processes running on the server in real time, so when a process suddenly spikes like a backup job or rogue script, you catch it instantly. IT teams can terminate the process on the spot and prevent the server from slowing down or going offline.

## Get real-time visibility without overloading your network

### See only what truly matters, live

- OpManager lets you choose how long you want to view live performance graphs, so you're always watching the metrics that actually matter in the moment.

### Control your refresh rate for lighter, smarter monitoring

- Set the refresh interval to just a few seconds for real-time insights, or slow it down when you don’t need second-by-second updates, keeping both your devices and OpManager running effortlessly.

### Real-time insights without the overwhelm

- By allowing you to filter the time window and metric depth, OpManager ensures that critical data comes through instantly without adding unnecessary load on your infrastructure.

### Designed for high visibility, low noise

- OpManager’s real-time monitoring highlights the spikes and dips that actually matter so you’re not buried in raw data, and troubleshooting becomes faster and decisions far more confident.

## The complete real-time toolkit - ManageEngine OpManager

### Dashboards & NOC views
