# Field Reference

Real-Time Logpush allows you to select custom fields to include in your exported logs.\
Fields are grouped by category to help you identify which data points are relevant for performance analysis, debugging, or analytics integration.

Each field represents a specific CDN request or response attribute processed by Medianova’s edge servers.

All logs are delivered in **JSON Lines (`.jsonl`)** format, with each field represented as a key–value pair.

### **Validate a Log File**

Use standard CLI tools to check integrity and content of `.jsonl.gz` files:

```bash
# Decompress and preview
gunzip -c logs-2025-04-13-23-55.jsonl.gz | head -n 3

# Validate JSON structure
jq empty logs-2025-04-13-23-55.jsonl
```
