Kubernetes Events

​

Overview

Unlike standard Kubernetes clusters where events are ephemeral and typically expire after an hour, Metoro provides permanent storage and analysis of all Kubernetes events. This allows you to track, analyze, and debug cluster activities over extended periods.

​

Event Storage

Key features of Metoro’s event storage:

• Permanent Storage: Events are retained for the full retention period
• Complete History: Records creation, updates, and deletion of events
• Service Association: Events are automatically linked to relevant services
• Cross-Cluster View: View events across all your clusters in one place

​

Event Attributes

Each event in Metoro contains rich metadata:

• Type: Warning or Informational
• Resource Name: The affected resource
• Service Name: Associated service (Metoro-specific enhancement)
• Reason: The event trigger
• Message: Detailed event description
• Namespace: The involved object’s namespace
• Object Kind: The type of resource involved
• Reporting Component: Source component (e.g., Horizontal Pod Autoscaler)
• Count: Number of times the event has occurred

​

Viewing Events

​

Global Events View

Access the dedicated Kubernetes events view to:

• See events across all clusters
• Filter by any event attribute
• Search event messages using regex
• Track event frequency and patterns

​

Service-Specific Events

View events for specific services:

1. Navigate to a service
2. Open the Events tab
3. View all events associated with the service

​

Filtering and Search

​

Attribute Filtering

Filter events by any attribute:

• Event type (Warning/Informational)
• Service name
• Namespace
• Resource kind
• Reporting component

​

Message Search

Use regex search to find specific events:

# Find HPA scaling failures
HPAfailed

# Find container crashes
container.*Error

# Find scheduling issues
FailedScheduling

​

Best Practices

1. Regular Monitoring:

• Review warning events daily
• Track event patterns across services
• Monitor high-frequency events

2. Troubleshooting:

• Use service association to correlate events
• Combine event data with logs and metrics
• Track event history for recurring issues

3. Filtering Strategy:

• Create saved filters for common scenarios
• Use regex for complex pattern matching
• Filter by service for targeted analysis
