Text Filter

---

Description

The Text Filter processor filters events based on text field content. It allows you to:

• Match exact text strings
• Check for text containment
• Filter events based on text criteria
• Route events based on text content

---

Required Input

The processor requires an input event stream containing at least one text field to filter on.

---

Configuration

Text Field

Select the field containing the text that should be filtered.

Operation

Choose from two filtering operations:

• MATCHES: Exact string matching (case-sensitive)
• CONTAINS: Substring matching (case-sensitive)

Keyword

Specify the text string to match against.

Output

The processor forwards the input event only if the text field satisfies the filter condition.

Example

Input Event

{
  "message": "Temperature warning: 25.5°C",
  "timestamp": 1586380104915
}

Configuration

• Text Field: message
• Operation: CONTAINS
• Keyword: warning

Output Event

{
  "message": "Temperature warning: 25.5°C",
  "timestamp": 1586380104915
}

Use Cases

1. Event Routing

   • Route events based on text content
   • Filter log messages
   • Process specific error messages
   • Handle different event types

2. Content Filtering

   • Filter text-based alerts
   • Process specific keywords
   • Extract relevant messages
   • Filter notifications

3. Data Validation

   • Validate text content
   • Ensure required text patterns
   • Filter invalid messages
   • Enforce text standards

Notes

• Text matching is case-sensitive
• The processor preserves the original event structure
• No text transformation is performed
• Events that don't match the filter are dropped
• The filter operates on the exact text field value
