What is Infrastructure Monitoring?
Infrastructure Monitoring is the process of monitoring network infrastructure for vulnerabilities. Infrastructure monitoring tools monitor the health status, availability, and performance of devices throughout the network.
If an issue is detected the user is sent a notification that a problem has been found. The user can then use the infrastructure monitoring tool to generate a report to look deeper at the causes of the problem.
Using an infrastructure monitoring tool is important because attempting to stay on top of network events manually would be next to impossible. A network administrator could not realistically keep track of all physical and virtual resources.
The abundance of cyber threats online has made it a necessity to protect networks with infrastructure monitoring software. More sophisticated threats have led to a need for more advanced network monitoring.
To keep you protected against the latest threats, the best infrastructure monitoring tools can be used to:
- Automatically discover connected devices
- Create custom dashboards
- Show visual displays for network performance (Charts, graphs, dials etc.)
- Alert you through email and SMS once devices experience problems
- Generate reports
Here is a list of the best infrastructure monitoring tools:
- SolarWinds Network Performance Monitor (FREE TRIAL)
- PRTG Network Monitor (FREE TRIAL)
- SolarWinds Server and Application Monitor (FREE TRIAL)
- ManageEngine OpManager
- Nagios XI
- Icinga 2
