Automated ClickHouse Capacity Alerts
Every hour, WebRun opens the ClickHouse Cloud console, checks disk usage and p99 query latency for every service against the threshold you set, posts a Teams alert naming any service near capacity, and schedules a maintenance window on Google Calendar for a breach.
How do I get alerted before a ClickHouse service runs out of disk space?
WebRun checks ClickHouse Cloud every hour, comparing disk usage and query latency for every service against the threshold you set. A breach posts a Microsoft Teams alert naming the service and how close it is to capacity, and schedules a maintenance window on Google Calendar, so a service never runs out of headroom without warning.
- Capacity issues get caught within the hour, not after an outage
- Every breach comes with a scheduled maintenance window, not just a ping
- Resolved services can have their maintenance window cancelled

How is each run configured?
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.
Every action is checked against this policy before it runs.
Questions, answered
Will it resize the cluster or add storage on its own?
No. WebRun only reports usage against threshold. Resizing a service or adding storage is left to a human.
How does it decide a service needs attention?
It compares disk usage and p99 query latency against the threshold you set per service, so the alert reflects your own capacity plan, not a generic default.
What if usage drops back down before the maintenance window?
It reads live usage from ClickHouse Cloud every run, so a service that's back under threshold before the scheduled window can have the meeting cancelled.
