Threshold Alert

A threshold alert is an automated notification that fires when a monitored metric crosses a defined boundary–revenue below a floor, error counts above a ceiling, inventory under a minimum.

Threshold alerts are the workhorse of data monitoring: pick a metric, pick a line, get told when the line is crossed. "Alert me when daily signups drop below 50" encodes a business rule a human would otherwise have to remember to check–and humans forget, especially on weekends, which is precisely when things break unobserved. Good threshold alerts are specific (one metric, one boundary), actionable (the recipient knows what to do), and calibrated–set the line too tight and alert fatigue sets in, too loose and it never fires until the damage is done.

Fig — every answer ships with the tables, rows and SQL behind it.
