Datadog Logs

Datadog Logs API

CLI Command

# Basic search (last 15 minutes)
dd search-logs 'env:prod service:my-service error'

# Custom time range
dd search-logs 'env:prod error' --from now-1h --to now

# Search Flex Logs tier (for archived/long-retention logs)
dd search-logs 'env:prod' --storage-tier flex --from now-30d

# Multi-service search with OR
dd search-logs 'env:prod service:(service-a OR service-b) order-12345' --storage-tier flex

# Fetch all pages
dd search-logs 'env:prod' --all-pages --limit 100

Query Syntax

The query syntax matches Datadog's Log Explorer. Pass it directly to --query:

# Attribute search
env:prod status:error

# Boolean operators
service:(api OR web) AND status:error

# Free text search
"connection timeout"

# Full-text search across all fields
*:order-12345

# Exclusions
env:prod -status:info

Storage Tiers

Important: If you don't see results, check if logs are in Flex tier. The Datadog UI has a toggle "Include Flex Logs" - this CLI flag is the equivalent.

Options

Common Patterns

# Search for UUID across services
dd search-logs 'env:prod service:(svc-a OR svc-b) fb13dc8c-8552-429b-b2d9-8897bfdcfb0e' \
  --storage-tier flex --from now-30d

# Find errors in last hour
dd search-logs 'env:prod status:error' --from now-1h

# Search specific host
dd search-logs 'env:prod host:web-01 status:error'
