Troubleshooting with the system log¶

Scenario: users report that a flow times out. Reproduce the issue while watching the log.

Recent errors¶

Get-SnowSyslog -Level error -Last 50

By default Snowplow returns rows from the last 15 minutes, capped at 100.

Follow the log like `tail -f`¶

Get-SnowSyslog -Wait -Pretty -Source 'Flow Engine' -Message timeout -PollSeconds 10

Trigger the flow in another window; matching rows print as they arrive. Press Ctrl+C to stop.

Rank the noisiest sources¶

Get-SnowSyslog -Level error -Since (Get-Date).AddHours(-2) -Last 500 |
    Group-Object source | Sort-Object Count -Descending |
    Select-Object -First 5 Name, Count

Check slow transactions or a scoped app¶

Get-SnowSyslog -Table syslog_transaction -Since (Get-Date).AddMinutes(-30) -Last 200
Get-SnowSyslog -Table syslog_app_scope -Level error -Last 100

Capture evidence for a ticket¶

Get-SnowSyslog -Level error -User integration.user -Last 200 |
    Export-SnowRecord -Format Json -Path .\integration-errors.json
