Access Level

The level of access (full or limited) that the monitoring service has to the selected target.


Determine what happens when a SQL Sentry condition is met (i.e. send an email, log to database, execute PowerShell, etc.).

Advisory Conditions

Event category applicable to customized alerting based on performance counter metrics, query results, or duration of events. Example: CPU > 90%.

Audit Conditions

Event category applicable to various activities carried out inside and outside of the SQL Sentry client. Example: Performance counter added, snooze status changed, watched flag changed, and more.



Describes the various states of an event object or associated performance counter (i.e. CPU > 90%).

Configuration Client

Local client installed for SentryOne Monitor to configure the monitoring environment.

Controller Service

Allows the SQL Sentry components (such as the monitoring service) to be remotely managed when using the Enhanced Platform Installer (EPI).


EHO Score

The Environment Health Overview score view works by incorporating alerts and their associated severity to calculate the scores. A high health score (with a maximum of 100 possible) is an indicator of good health. The score for these views is based on the severity of all open alerts within the selected time period. The severity points are as follows: Info - 0 points, Low - 1 point, Medium - 3 points, High - 6 points, Critical - 9 points The weight of an open alert diminishes with its age. The score being presented is 100 minus the sum of the weighted value of open alerts. Closed alerts are not factored into the score.


The Enhanced Platform Installer allows for the automation of upgrades and deployments of the SQL Sentry platform with a command line interface experience.

Event Chains

Series of dependencies between events running on the same server or different servers.

Event Conditions

A category of alerts applicable to events on watched targets. Examples: A deadlock occurred, there is blocking SQL, a SSAS command exceeded its maximum duration threshold, a Windows task failed, and more.

Event Object

Any job, task, or other event type that can be managed using SQL Sentry.

Event Source

Represents a unique instance of an event provider operating over a single event store connection. Examples include SQL Server Agent Jobs and Windows Tasks.


Failsafe Conditions

Event category applicable to connection status and error situations. Examples: A watched Azure SQL Database is online or offline (status changed from one to the other), a configured action failed to execute, and more.

SentryOne Test Actions

Test components that produce an outcome, and are needed to perform the test assertion. Information returned from actions are stored in resources, and actions often use assets or resources as part of their input.

SentryOne Test Annotations

Annotations allow meaningful descriptions to be assigned to tests and appear on the test management page for a test.

SentryOne Test Assembly Run Logs

Displays details about the test assembly runs within your testing environment.

SentryOne Test Assert

Test component that’s used to test the results of actions. Asserts compare the values in resource keys to each other, or to a static value entered into the Assert.

SentryOne Test Assertions

Assertions contain test validations that determine if a test passes or fails. Assertions run immediately after all execution tracks for the current test are complete, and compare expected data to actual data generated during the execution tracks. The results of these data comparisons dictate whether the test passes or fails.

SentryOne Test Asset

Items that the action needs in order to run (connection strings, queries, package references, etc.).
