Scout triggers and actions

Triggers - events that are defined by the user, for example: The CPU Utilization of the database machine is over 90%.

Actions - the measures that the user defines for the system to take if a certain triggers (conditions) are met.

Select Database(s) - allows you to choose one or more database instances to apply the rule to.

​

Trigger Types

• Query pattern - the action(s) will be triggered when the current query matches the given query pattern.
• Query Duration - the action(s) will be triggered when the current query duration is greater than the specified duration.
• User(s) - the action(s) will be triggered when a user or users are connecting to the database.
• IP(s) - The action(s) will be triggered when a host with a specific IP address connects to the database.
• Database Name - The action(s) will be triggered when a certain database schema is accessed by a user.
• Connection Utilization - The action(s) will be triggered when the connection utilization to a certain Database(s) exceeds a certain percentage.
• Custom Script - The action(s) will be triggered when a custom script, provided by the user, runs and finds processes which will be killed by the system.

​

Trigger Operator Types

• In - this operator is relevant to the Trigger types: User(s) and IP(s), and allows us to define a few IP addresses or Users that will trigger the action(s) defined.
• Not In - similar to the operator In, but it is used for triggering an action when the IPs or Users are not included in the given list.
• Like - this operator is relevant to the Trigger types: Query Pattern, and it allows us to define a pattern that includes a few queries that will trigger the action(s) defined.
• Not Like - similar to the operator Like, but it is used for triggering an action when the given query pattern does not include the current query.
• Is Greater Than - this operator is relevant to the Trigger type Query Duration.

​

Trigger Values

• Query pattern - the string of the query pattern.
• Query Duration - the time above which the action will be triggered.
• User(s) - a comma separated list of a User(s).
• IP(s) - a comma separated list of IP(s).
• Database Name - a comma separated list of name(s) of the relevant database schema(s).
• Connection Utilization - a percentage value above which the action(s) will be triggered.
• Custom Script - the relevant script.

​

Action Types

• No Action - No action will be taken. Useful when only a notification is wanted.
• Kill Connection - Kill the connections which were defined, like a query pattern.
• Rate Limit - Limit the rate of a certain connection that match the trigger value.
• Lock - Lock a certain User(s) or IP(s) etc’ out of the system.
• Kill idle connections - All idle connection will be killed when the trigger value is matched.

​
