Engineer Briefing

Building a network is only the beginning.

Once a network is deployed, engineers must continuously monitor it to answer questions like:

• Is the network healthy?
• Are devices online?
• Is bandwidth being overused?
• Has a link failed?

Without monitoring, engineers only discover problems after users complain.

Mission Objectives

By the end of this mission, students should understand:

• Why network monitoring is important.
• What SNMP is.
• The purpose of logs.
• Alerts and notifications.
• Basic network monitoring tools.
