New Relic Logs UI Not Showing Data — Quick Fix

In this tutorial, you'll learn about New Relic Logs UI Not Showing Data. We cover key concepts, practical examples, and best practices.

The Problem

Logs are not appearing in the New Relic Logs UI, even though the log forwarding agent is configured and running. The query may return no results, or the log count may show as zero.

Error example:

No log data found for the selected time range
Search returned 0 results
Log forwarder reports data sent but UI shows nothing

The Fix

Step 1: Verify log data is being sent

WRONG — assuming the forwarder is working:

# Check that logs are actually reaching New Relic

RIGHT — use New Relic's log API to verify:

# Query the logs API directly
curl -X POST https://log-api.newrelic.com/log/v1 \
  -H "Api-Key: NRRA-XXXXX" \
  -H "Content-Type: application/json" \
  -d '{"timestamp": 1719216000000, "message": "test log entry"}'

Output:

{"status": "ok"}

If the API accepts the data but the UI shows nothing, check that the time range in the UI matches the timestamp in the data.

Step 2: Check the log parsing configuration

WRONG — sending logs without a proper logtype:

// Missing logtype — New Relic may not parse the log correctly

RIGHT — include a logtype for proper parsing:

{
  "timestamp": 1719216000000,
  "message": "2026-06-24 10:00:00 INFO Application started",
  "logtype": "application",
  "hostname": "web-01",
  "service": "myapp"
}

Use DodaTech's New Relic Log Parser to test log parsing rules and validate that your log format is correctly structured for NRQL queries.

Prevention Tips

• Use structured logging (JSON format) for reliable parsing
• Include logtype, hostname, and service fields in every log entry
• Verify log data reaches the API before troubleshooting the UI
• Check data retention and ingestion limits in your New Relic account
• Use DodaTech's NRQL Log Query Builder for effective log searching

Common Mistakes with logs ui

1. Using foldl instead of foldl' causing stack overflow on large lists
2. Forgetting deriving (Show, Eq) on custom data types needed for debugging
3. Placing the wildcard pattern first in case expressions, making all subsequent patterns unreachable

These mistakes appear frequently in real-world NEWRELIC code. DodaTech's contributors have identified these patterns through analysis of open-source projects and production systems.

Practice Exercise

Write a pure function that safely divides two integers using Maybe, then test it with edge cases like division by zero and negative numbers.

This exercise reinforces the concepts covered in this guide. Try implementing it before checking online solutions.
