Network intelligence tools in GCP - Step-by-Step Execution

Process Flow - Network intelligence tools

Start: User wants network info

↓

Choose tool: VPC Flow Logs, Network Intelligence Center, or Packet Mirroring

↓

Collect network data

↓

Analyze data for traffic, latency, or security

↓

Generate insights or alerts

↓

User takes action or monitors

↓

End

This flow shows how GCP network intelligence tools collect and analyze network data to help users monitor and improve their network.

Execution Sample

GCP

1. Enable VPC Flow Logs on subnet
2. Send logs to Cloud Logging
3. Use Network Intelligence Center to view topology
4. Analyze logs for traffic patterns
5. Set alerts for anomalies

This sequence shows how to enable and use GCP network intelligence tools to monitor network traffic and detect issues.

Process Table

Step	Action	Input/Condition	Output/Result
1	Enable VPC Flow Logs	Subnet selected	Flow logs start collecting network traffic data
2	Send logs to Cloud Logging	Flow logs enabled	Logs available in Cloud Logging for analysis
3	View topology in Network Intelligence Center	Logs available	Visual network map displayed
4	Analyze logs	Logs in Cloud Logging	Traffic patterns and latency identified
5	Set alerts	Analyzed data	Alerts configured for unusual network behavior
6	Monitor alerts	Alerts configured	User notified on network issues
7	End	No further action	Monitoring ongoing

💡 Monitoring continues until user disables tools or changes configuration

Status Tracker

Variable	Start	After Step 1	After Step 2	After Step 3	After Step 4	After Step 5	Final
VPC Flow Logs	Disabled	Enabled	Enabled	Enabled	Enabled	Enabled	Enabled
Cloud Logging	No logs	No logs	Logs received	Logs received	Logs received	Logs received	Logs received
Network Topology View	None	None	None	Visible	Visible	Visible	Visible
Alerts	None	None	None	None	Configured	Active	Active

Key Moments - 3 Insights

Why do we enable VPC Flow Logs before viewing network topology?

VPC Flow Logs must be enabled first to collect network traffic data, which Network Intelligence Center uses to build the topology view (see execution_table step 1 and 3).

What happens if logs are not sent to Cloud Logging?

Without logs in Cloud Logging, analysis and alerts cannot be performed, so steps 4 and 5 would have no data to work with (see execution_table step 2).

Can alerts notify users without analyzing logs first?

No, alerts depend on analyzed data from logs to detect anomalies, so analysis must happen before alerts are set (see execution_table steps 4 and 5).

Visual Quiz - 3 Questions

Look at the execution table, at which step does the network topology become visible?

A Step 2

B Step 3

C Step 4

D Step 5

💡 Hint

Check the 'Output/Result' column for when the topology is displayed.

According to the variable tracker, what is the state of 'Alerts' after Step 4?

A None

B Active

C Configured

D Disabled

💡 Hint

Look at the 'Alerts' row under 'After Step 4' in the variable tracker.

If VPC Flow Logs were not enabled at Step 1, how would that affect Step 3?

A Logs would be sent anyway

B Topology would still be visible

C Topology would not be visible

D Alerts would be configured automatically

💡 Hint

Refer to the dependency between Step 1 and Step 3 in the execution table.

Full Transcript

Network intelligence tools in Google Cloud Platform help users monitor and understand their network traffic. The process starts by enabling VPC Flow Logs on a subnet, which collects network traffic data. These logs are sent to Cloud Logging, where they are stored and can be analyzed. Using the Network Intelligence Center, users can view a visual map of their network topology based on the collected data. Analysis of logs helps identify traffic patterns and latency issues. Users can then set alerts to be notified of unusual network behavior. Monitoring continues as long as these tools are enabled, helping maintain network health and security.
