## About
The `looker-health-pulse` tool performs health checks on a Looker instance. The `action` parameter selects the type of check to perform:
- `check_db_connections`: Checks all database connections, runs supported tests, and reports query counts.
- `check_dashboard_performance`: Finds dashboards with slow running queries in the last 7 days.
- `check_dashboard_errors`: Lists dashboards with erroring queries in the last 7 days.
- `check_explore_performance`: Lists the slowest explores in the last 7 days and reports average query runtime.
- `check_schedule_failures`: Lists schedules that have failed in the last 7 days.
- `check_legacy_features`: Lists enabled legacy features. (*To note, this function is not available in Looker Core. You will get an error running this command with a Core instance configured.*)
