b2c-logs

description

Retrieve and search logs from B2C Commerce instances using the b2c CLI. Use this skill whenever the user needs to view server logs, search for errors, filter log entries by level or time, or monitor logs in real-time. Also use when the user reports a 500 error, broken checkout, failing job, or any server-side issue that needs log investigation — even if they just say "something's broken on the sandbox" or "check the logs".

B2C Logs Skill

Use the b2c CLI to retrieve and monitor log files on Salesforce B2C Commerce instances. The logs get command is designed for agent-friendly, non-interactive log retrieval with structured JSON output.

Tip: If b2c is not installed globally, use npx @salesforce/b2c-cli instead (e.g., npx @salesforce/b2c-cli logs get).

Configuration & Authentication

The CLI auto-discovers the target instance and credentials from SFCC_* environment variables, dw.json in the current or parent directories, ~/.mobify, package.json, and configuration plugins. Flags like --server, --client-id, --client-secret, --username, and --password are usually unnecessary — only pass them to override what's auto-detected.

Run b2c setup inspect to see the resolved configuration and which source provided each value (use --json for scripting, --unmask to reveal secrets). For precedence rules and troubleshooting, see the b2c-cli:b2c-config skill.

Agent-Friendly Log Retrieval

The logs get command is optimized for coding agents:

• Exits immediately after retrieving logs (non-interactive)
• Supports --json for structured output
• Filters by time, level, and text search
• Auto-normalizes file paths for IDE click-to-open

Examples

Get Recent Logs

# Get last 20 entries from error and customerror logs (default)
b2c logs get

# Get last 50 entries
b2c logs get --count 50

# JSON output for programmatic parsing
b2c logs get --json

Filter by Time

# Entries from the last 5 minutes
b2c logs get --since 5m

# Entries from the last 1 hour
b2c logs get --since 1h

# Entries from the last 2 days
b2c logs get --since 2d

# Entries after a specific time (ISO 8601)
b2c logs get --since "2026-01-25T10:00:00"

Filter by Log Level

# Only ERROR level entries
b2c logs get --level ERROR

# ERROR and FATAL entries
b2c logs get --level ERROR --level FATAL

Search Text

# Search for "OrderMgr" in messages
b2c logs get --search OrderMgr

# Search for payment errors
b2c logs get --search "PaymentProcessor"

Combined Filters

# Recent errors containing "PaymentProcessor"
b2c logs get --since 1h --level ERROR --search "PaymentProcessor" --json

# Last hour of errors and fatals from specific log types
b2c logs get --filter error --filter warn --since 1h --level ERROR --level FATAL

List Available Log Files

# List all log files
b2c logs list

# List specific log types
b2c logs list --filter error --filter customerror

# JSON output
b2c logs list --json

Real-Time Tailing (Human Use)

For interactive log monitoring (not for agents):

# Tail error and customerror logs
b2c logs tail

# Tail specific log types
b2c logs tail --filter debug --filter error

# Tail only ERROR and FATAL level entries
b2c logs tail --level ERROR --level FATAL

# Tail with text search
b2c logs tail --search "PaymentProcessor"

# Combined filtering
b2c logs tail --filter customerror --level ERROR --search "OrderMgr"

# Stop with Ctrl+C

Downloading Full Log Files

To download the complete log file, use the file field from the JSON output with b2c-cli:b2c-webdav:

b2c webdav get error-odspod-0-appserver-20260126.log --root=logs -o -

JSON Output Structure

When using --json, logs get returns:

{
  "count": 1,
  "entries": [
    {
      "file": "error-odspod-0-appserver-20260126.log",
      "timestamp": "2026-01-26 04:38:03.022 GMT",
      "level": "ERROR",
      "message": "PipelineCallServlet|156679877|Sites-Site|...",
      "raw": "[2026-01-26 04:38:03.022 GMT] ERROR PipelineCallServlet|..."
    }
  ]
}
