Common AWS Network Dashboard Problems

AWS

AWS Network Dashboard users often face several issues that can hinder their ability to monitor and manage their network effectively. Let's explore the most common problems:

Wrong Data

Incorrect metrics and slow updates can lead to poor network tracking. Users have reported instances where the dashboard shows inaccurate information, potentially causing misguided decisions. For example:

"About two weeks ago all three of our Aurora DB instances in eu-central-1 suddenly crashed and were offline, to no avail, for almost 55 minutes. Simultaneously we had random network problems going on within our eu-central-1 VPC which we were unable to diagnose. We still don't know what happened because we're not getting any answers to our support request. The AWS health dashboard was all green the entire time. No notifications were sent out."

This user experience highlights how wrong data can mask serious issues and delay problem resolution.

Display Issues

Broken graphs and incomplete charts make data hard to understand. Users might see:

  • Missing data points
  • Graphs that don't load properly
  • Charts cutting off important information

These display problems can lead to misinterpretation of network health and performance.

Login and Access Problems

Users often face difficulties getting into the dashboard. Common issues include:

  • Loading errors
  • Permission failures
  • Timeout errors when trying to access the console

To address these, users should check their internet connection, try different browsers, and review their IAM policies, especially those containing the aws:SourceIp or aws:SourceVpc global condition key.

Slow Performance

Slow loading times and unresponsive controls can make the dashboard hard to use. This issue is often linked to the dashboard's update frequency. As one user noted:

"Correct. No matter how down AWS is, their status page will only show a disruption if a manager approves showing a disruption. There is nothing automated to display the status, so the status page is mostly worthless except for whatever AWS admits is down."

This manual approval process can lead to delays in reporting disruptions, affecting the dashboard's usefulness for real-time monitoring.

To help users navigate these issues, here's a quick reference table:

Problem Possible Cause Quick Fix
Wrong Data Slow updates, sync issues Check data sources, wait for sync
Display Issues Browser compatibility, cache Clear browser data, try different browser
Login Problems Network config, IAM policies Review permissions, check network settings
Slow Performance Resource limitations, high traffic Optimize dashboard, check during off-peak hours

How to Fix Common Issues

When facing problems with your AWS Network Dashboard, try these solutions:

Check Data Sources

1. Enable CloudWatch metrics and VPC Flow Logs

Make sure these are turned on and set up correctly. Without proper data sources, your dashboard won't show accurate information.

2. Verify data in Logs Insights

Run your queries in Logs Insights to confirm data exists. As one user reported:

"I tried logging out and back in. I am in Chrome. I even tried going to the dashboard from Firefox, first time accessing from that browser, in case it was a browser caching issue. (I don't want to clear browser cache if I don't have to.)"

This user found that their query showed data in Logs Insights, pointing to a dashboard setup issue rather than a data problem.

Clear Browser Data

If you're seeing display issues:

  1. Log out and back in
  2. Try a different browser
  3. Clear your browser cache as a last resort

Check User Permissions

Review your IAM roles and policies. Common mistakes include:

Mistake Fix
Missing aws:SourceIp condition Add correct IP ranges
Incorrect aws:SourceVpc setting Update with proper VPC ID
Outdated IAM policy Review and update permissions

Speed Up the Dashboard

To improve dashboard performance:

  1. Use fewer widgets
  2. Adjust time settings for data display
  3. Check during off-peak hours

If issues persist, consider using the AWS CLI for checks or reviewing CloudWatch logs for more detailed troubleshooting.

Advanced Fixes

When basic troubleshooting steps don't resolve your AWS Network Dashboard issues, it's time to dig deeper. Here are some advanced fixes to try:

Use AWS CLI for Checks

AWS CLI

The AWS Command Line Interface (CLI) can provide valuable insights into your network health:

1. Check VPC Flow Logs

Run this command to view your VPC flow logs:

aws ec2 describe-flow-logs --filter Name=resource-id,Values=<your-vpc-id>

This helps identify traffic patterns and potential security issues.

2. Monitor CloudWatch Metrics

Use this command to get network-related metrics:

aws cloudwatch get-metric-statistics --namespace AWS/EC2 --metric-name NetworkIn --dimensions Name=InstanceId,Value=<your-instance-id> --start-time <start-time> --end-time <end-time> --period 300 --statistics Average

This shows network traffic data for a specific EC2 instance.

Use CloudWatch Logs

CloudWatch

CloudWatch Logs can reveal hidden issues:

  1. Open the CloudWatch console
  2. Go to "Logs Insights"
  3. Select your VPC flow log group
  4. Run this query to find rejected packets:
fields @timestamp, srcAddr, dstAddr, srcPort, dstPort, action
| filter action="REJECT"
| sort @timestamp desc
| limit 20

This helps pinpoint specific network issues, such as misconfigured security groups or network ACLs.

Contact AWS Support

If all else fails, reach out to AWS Support:

  1. Log into the AWS Support Center
  2. Click "Create case"
  3. Choose "Technical support"
  4. Include:
    • Your AWS account ID
    • The specific dashboard having issues
    • Steps you've taken to troubleshoot
    • Any error messages or screenshots

A support engineer from AWS will then assist you with your specific network dashboard problem.

Tips for Better Dashboard Management

To keep your AWS Network Dashboards working well, follow these key practices:

Check Dashboards Regularly

Make it a habit to review your dashboards often. This helps catch issues early and keeps your data accurate. For example, set a weekly reminder to:

  • Verify all metrics are updating correctly
  • Check for any unexpected spikes or drops in data
  • Remove outdated or unnecessary dashboard elements

Add Custom Metrics

Custom metrics let you track specific aspects of your network performance. Here's how to set one up:

1. Open the CloudWatch console 2. Choose "Metrics" > "All metrics" > "Create metric" 3. Select a namespace (e.g., "NetworkPerformance") 4. Define your metric (e.g., "PacketLoss") 5. Use this AWS CLI command to publish data:

aws cloudwatch put-metric-data --namespace NetworkPerformance --metric-name PacketLoss --value 0.5 --unit Percent

Remember, custom metrics cost $0.50 per metric per month, so choose wisely.

Set Up Auto-Alerts

Auto-alerts help you spot and fix dashboard issues quickly. To set up an alert:

1. In CloudWatch, go to "Alarms" > "Create alarm" 2. Choose the metric to monitor 3. Set your threshold (e.g., PacketLoss > 1%) 4. Define the action (e.g., send an SNS notification)

Pro tip: Use a script to feed data to your custom metrics continuously. This ensures your alerts are based on up-to-date information.
