General Concepts Of Microsoft Azure’s Network Watcher

1. Overview

  • What is ? Is the main dashboard which gives an overview of network performance.
  • An explanation: The central location to access features for network diagnostics, monitoring and management.

2. Topology

  • What visual map of network resources and connections.
  • Explained: Displays the connection between resources such as virtual machines, subnets and gateways.

3. Troubleshooting

  • Is a network test tool for determining the connectivity between a destination and a source.
  • Checks to see if traffic can get to a certain destination. Identifies network issues.

4. IP flow Verify

  • What does it do? Tests if an IP packet is valid (defined by the source IP, the destination IP and port). Can network security rules be passed through?
  • Explanation can help troubleshoot network access problems like firewalls.

5. Next Hop

  • Determining the next hop of network traffic for a VM.
  • Explained: Is useful for analyzing network traffic and understanding the routing path.

6. Security Group

  • What it does: Displays rules that are applied by the Network Security Groups (NSGs).
  • Helps verify the rules that affect inbound/outbound traffic.

7. Capture Packet

  • What is: Captures networks packets for detailed analyses
  • is similar to Wireshark. It can be used to troubleshoot network problems in detail.

8. Analytics for Traffic

  • What does: analyses network traffic patterns.
  • Explanation provides insights into network performance security and usage patterns.

9. (NSG Flowlogs)

  • Logs showing all network flows permitted and denied by NSGs.
  • Explanation Can be used for security audits or to identify suspicious behavior.

10. Alerts

  • What’s it all about? Notifications based off network activity.
  • Explanation Helps to notify you of issues and unusual activity automatically.
