Automated TimescaleDB Disk Usage Alerts

Every hour, WebRun checks each TimescaleDB instance's disk usage, chunk compression status, and slow query count, posts a status update to your ops Telegram group, and texts the on-call engineer through Twilio the moment disk usage crosses your set threshold.

TimescaleDB check disk and query health

Twilio text the on-call engineer

In short

How do I get alerted before a TimescaleDB disk fills up?

WebRun checks every TimescaleDB instance's disk usage, chunk compression, and slow query count every hour, posts the status to your ops Telegram group, and texts the on-call engineer through Twilio the moment disk usage crosses the threshold you set. Teams running time series workloads catch a filling disk before it becomes an outage.

A filling disk gets a text within the hour, not after it's full
The ops group always has current instance health in Telegram
Only real threshold breaches trigger a text, not routine checks

Built for database administrators · platform engineering teams · site reliability engineers

Setup & safety

Secure by default

Connect once, stays signed in

WebRun signs in once and keeps each session in a persistent environment, so every run picks up right where it left off.

Your credentials stay in your own private environment - WebRun never stores your passwords.

Good to know

Questions, answered

Does WebRun compress chunks or free up space itself?

No. It only reads disk and compression metrics. Compressing chunks, dropping data, or resizing storage stays a manual action.

What counts as a disk usage breach?

Whatever percentage threshold you set for each instance. Only crossing that line triggers the Twilio text.

Will routine checks also text me?

No. Texts only go out on an actual threshold breach. Routine healthy checks stay in the Telegram status update.

Put this on autopilot.
