Errors View

Track, analyze, and resolve errors in your Meteor application.

Overview

The Errors tab provides:

• Error timeline showing occurrences over time
• Grouped errors by type/message
• Error rate metrics
• Detailed stack traces

Error Timeline

The chart shows error occurrences over time:

• Height: Number of errors at each time point
• Color: Error severity (red = high, orange = medium)

Use the timeline to identify:

• Error spikes (deployment issues?)
• Patterns (time-based issues?)
• Trends (increasing/decreasing errors?)

Error List

Errors are grouped by:

1. Error message (normalized)
2. Stack trace fingerprint
3. Error type/code

Each row shows:

Column	Description
Error	Message and type
Count	Total occurrences
Users	Affected user count
Last Seen	Most recent occurrence
Status	Resolved/Unresolved

1. Click on an error
2. Click "Ignore"

Use sparingly

Only ignore errors that are truly expected and don't indicate issues.

Error Investigation

Step-by-Step Guide

1. Identify the scope

   • How many users affected?
   • When did it start?
   • Is it increasing?

2. Review the stack trace

   • What function threw?
   • What was the call path?

3. Check context

   • What method/subscription?
   • What were the arguments?
   • Who was the user?

4. Look for patterns

   • Specific user type?
   • Specific time of day?
   • After a deployment?

Setting Up Alerts

Get notified of important errors:

1. Go to Site Settings > Alerts
2. Create a new alert rule
3. Configure conditions:
   • Error rate exceeds X%
   • New error type detected
   • Specific error pattern

See Alerting Guide for details.
