Network Administrators Survival Guide

The topics covered in this chapter prepare the Netadmin for deploying network-monitoring systems to examine individual network devices and overall network availability. The Netadmins should be able to perform the following network-monitoring tasks:

  • Deploy a Linux-based unified network-monitoring system to monitor network nodes, including Cisco devices, network servers, and related services such as HTTP, FTP, and SMTP

  • Deploy a Windows-based unified network-monitoring system to monitor network nodes, including Cisco devices, network servers, and related services such as HTTP, FTP, and SMTP

  • Use the notification feature of the network-monitoring systems to alert on-call technicians about network issues

  • Use the reporting feature of network-monitoring systems to maintain SLAs Table 5-3 provides a summary of the network-monitoring tools that this chapter covers.
