Know before your ClickHouse® database does

CHOps alerting lets you define monitoring rules using SQL queries. Each rule is evaluated on a cron schedule across all nodes in your ClickHouse® cluster. When a threshold is breached, notifications are sent to email, Slack, Microsoft Teams, Google Chat, or PagerDuty.

Alerts are per-node aware: if 2 of 5 nodes breach a threshold, you receive 2 separate notifications, each identifying the specific node. Nodes that are unreachable are silently skipped.

Scheduled email reports let you automate recurring data delivery: run a SQL query on a cron schedule and email the results as a formatted HTML table.
