Static thresholds fail in both directions. Set them tight and the team mutes the channel by Friday. Set them loose and the real drop arrives with the monthly report.

What changed

Each monitor now builds an expected range from the metric’s own history, with weekly and yearly patterns. Signups that always dip on weekends stay quiet on weekends. The same dip on a Tuesday sends an alert.

Alerts that say why

When a number leaves its range, Tessel breaks it down by the segments you care about and leads with the one that moved most. Most alerts now arrive with the answer to the first question anyone asks.

Existing monitors switch to the new model automatically. You can compare the old and new thresholds on any monitor before it does.
