Mcloud Logs

Cloud CLI: Logs Command

Execute mcloud logs to fetch runtime logs for a Cloud environment's backend or storefront.

Constraints

• --follow and --json are incompatible. For programmatic log analysis, use bounded time windows with --from/--to and --json.
• --follow streams until interrupted with Ctrl+C — do not use in scripts or pipelines.
• Default retrieves the last 500 log lines from the past 15 minutes.

Examples

# Basic log fetch (last 500 lines, last 15 min)
mcloud logs --json

# Search for errors
mcloud logs --search error --limit 1000 --json

# Filter for HTTP 500 errors via metadata
mcloud logs --metadata status=500 --limit 1000 --json

# Logs for a specific deployment (build or deployment ID)
mcloud logs --deployment bld_01ABC123 --json

# Structured output for agent analysis
mcloud logs --search error --json | jq '.[] | {timestamp, source, message}'

# Storefront logs
mcloud logs --type storefront --json

# Stream live logs (human-readable, not for scripts)
mcloud logs --follow

# Logs within a specific time range
mcloud logs --from 2026-04-22T10:00:00Z --to 2026-04-22T11:00:00Z --limit 1000 --json

# Logs from a time until now
mcloud logs --from 2026-04-22T10:00:00Z --json

# Multiple source filters
mcloud logs --source api --source worker --json

# Multiple metadata filters (HTTP 4xx and 5xx)
mcloud logs --metadata status=400 --metadata status=500 --limit 500 --json

Time Range Notes

• Default window is the past 15 minutes.
• Pass --from without --to to fetch from a time until now.
• Pass --to without --from only if --to is within the last 15 minutes; otherwise also pass --from.
• Both --from and --to accept ISO 8601 timestamps.
