Server Health Status provides you with a high-level view of the health of your environment.
Some functionality of the Server Health Status is dependent on the use of Advisory Conditions. In addition to your own Advisory Conditions, download the latest Advisory Conditions Pack from the Tools menu in the SentryOne client. This pack includes many Advisory Conditions that assist in monitoring performance issues, such as high CPU usage, disk waits, and more.
There are three View by options for the pages in the SentryOne Cloud. The Server Health Indicator and Score display different information depending on the view you're using.
Wait Time / Session Wait Time / Session relies on wait stats data that are collected by SentryOne. These wait stats are broken down by major resource category (Network, CPU, Memory, Disk, Other). The Other category is for other important wait types that either affect performance in more than one major category, or can't be directly attributed to any category with absolute certainty, such as backups and parallelism respectively. Each category is calculated independently. The displayed value for a category is calculated as the waits for the category divided by the user sessions. The values for waits and user sessions are based on the most recent values present in the selected timeframe. Each value is then rounded and displayed as the category's value. The overall score is the sum of the five rounded categories.
Note: The weight of an open event diminishes with its age. The score being presented is 100 minus the sum of the weighted value of open events.
Closed events are not factored into the Server Health score. Events can be closed in the Events Log in the SentryOne client.
The Health Indicator provides a visual representation of a server's health.
As these waits increase, the corresponding section begins to fill and the Health Indicator begins to change color, going from green to yellow to red.
Events by Tag In the Events by Tag view, each section represents the tags that are applied to the Advisory Conditions in your environment.
Events by Severity In the Events by Severity view, the Health Indicator is divided into quadrants representing Low, Medium, High, and Critical Advisory Conditions.
Each Health Indicator contains a corresponding Health Score. Scores give you a metric to use to quickly evaluate your server's health.
Wait Time/ Session In this view, the health score worsens as waits increase. A low health score is an indicator of good health.
Events by Tag In this view, the health score is calculated by severity of all open Advisory Condition events within the selected time period. A high health score is an indicator of good health.
Events by Severity In this view, the health score is calculated by severity of all open Advisory Condition events within the selected time period. A high health score is an indicator of good health.
Each Health Indicator has an Uptime chart. The Uptime chart indicates any downtime that occurred within the defined timeframe. Downtime displays as a red gap within the chart. Uptime percentage is displayed below the chart.
Note: The SentryOne App displays Uptime data with a percentage.
The Events Log provides the user with a listing of Advisory Condition Events for synced servers. Actual evaluation values aren't provided within the cloud; only the opened and closed status of the Advisory Conditions is provided.
View the Events Log at the instance level, or globally. The Events Log displays any Advisory Condition events that were active during the time period that's selected. This period can be adjusted by using the Time Period Filter in the top right corner.
