# Introduction SnowKill is a near real-time query monitoring tool for [Snowflake Data Cloud](https://www.snowflake.com/). SnowKill helps to detect potential problems with queries which **are currently running**. It analyzes query stats and plans, detects bad patterns, generates notifications and optionally "kills" some queries automatically. The core logic of SnowKill relies on internal REST API calls instead of SQL queries. It does not require an active warehouse to run, which makes it possible to maintain the constant monitoring almost free of charge. SnowKill has programmatic access to query plan from ["Query Profile"](https://docs.snowflake.com/en/user-guide/ui-query-profile) page in SnowSight. SnowKill also has access to information about locks and tries to report the exact reason for transaction collisions. SnowKill operates on present data, which normally allows it to react much faster relative to conventional monitoring tools operating on past data from [`QUERY_HISTORY`](https://docs.snowflake.com/en/sql-reference/account-usage/query_history) and [`GET_QUERY_OPERATOR_STATS`](https://docs.snowflake.com/en/sql-reference/functions/get_query_operator_stats). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.snowkill.net/introduction.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
