What should be monitored?
Active network monitoring is a must to gain accurate and real-time visibility of the health of your network. However frequent monitoring can become a huge strain on your network resources as it generates a lot of traffic on the network, especially in large networks.
We recommend monitoring only the critical devices on the network. This is a best practice adopted by the network administrators worldwide.
Following are the components of networks that are considered critical:
- WAN Infrastructure: Routers, WAN Switches, Firewall, etc.
- LAN Infrastructure: Switches, Hubs, and Printers.
- Servers, Services, and Applications: Application Servers, Database servers, Active Directory, Exchange Servers, Web servers, Mail servers, CRM Applications, etc.
- Host Resources: CPU, Memory, and Disk Utilization of critical devices.
- Critical Desktops and Workstations.
- Virtual machines: VMware, ESX/ESXi servers, HyperV, Xen servers and related guest virtual machines.
