I don't know which n8n workflows actually run and which sit idle

n8n's own executions view shows runs per workflow, but without your own dashboards you miss trends and silent failures. A custom monitoring table with N8N_LOG_LEVEL and webhook status makes it manageable.

Try this first

1. 1Enable execution-data persistence for all workflows in n8n (Workflow settings > Save executions). Otherwise runs disappear after retention.
2. 2Build a meta-workflow that hourly queries the Postgres execution table: runs per workflow, error rate, last-run time.
3. 3Push output to a table or a Slack report. Weekly trend: workflows that stopped, workflows with growing error rate.
4. 4Self-host: also monitor the container itself (CPU, RAM, restart count) with an external uptime monitor. n8n events say nothing about crashes.
5. 5Document each workflow's SLA: how often should it run, what is acceptable failure. Otherwise the monitor can't tell when something's off.

None of the above fits?
