# Result Values ## Result Values In Synthetic Monitoring, various processes and formulas are used to calculate result values. ## Result Severity Check results can be assigned different severities, depending on the resulting value. |

Result

| When a check runs, it returns a **result**—for example, a response time value. | |

Severity

|

Depending on the check type, the result value will result in a severity level for the check, displayed in the various views in Synthetic Monitoring.

Severity is a level indicator used to indicate the status of a check based on the results. The severity is used in various displays and alerts, notifications, and events.

| |

Check Status

|

Four colors represent the current check status

The colors are used in any context where the check status is displayed.

| |

Configuration

|

The configuration of the check affects how the value is converted into a severity.

The result interpretation settings apply some modifications to the result. For example, You can ignore particular combinations of file types and HTTP response codes.

A failed check will, by default, get the severity Fatal.

This can be configured to a different severity with the Check Fail Severity setting.

| |

Preserve Value

|

With the Preserve Value setting enabled, the returned value will be used and included in aggregated/calculated values.

Note: When a check has failed, the return value is considered Null, and there is no value to store.

| |

Thresholds

|

The various Threshold settings are used to select a severity for the check result.

The thresholds define an upper (High) and lower (Low) bound on the result for Warning and Error. Values above and below these bounds will cause the corresponding severity.

Note: Preserve that value must enable the thresholds to have any effect since it uses the result value.

| |

Mapping

| In addition to the thresholds, you can also configure Severity Mapping to customize rules to assign severities to different error types. | ## Result Value SLA In Synthetic Monitoring, SLA is calculated according to a formula, based on the duration of the result types. ### Calculation SLA calculations are affected negatively by the number of Fatal and Error results in a check. The formula is: (`info` + `warning`) / `total` | **Item** | **Description** | | --------- | ---------------------------------------------------------------------------------------------- | | `Info` | The duration that the check has the severity Information. | | `Warning` | The duration that the check has the severity Warning. | | `Total` | The sum of the duration of all the severities including Information, Warning, Error and Fatal. | #### Example: Let´s say that for the period of 11:00 – 12:00 our check has the following severities: 11:00-11:10 `Error`, duration = 10 min 11:10-11:20 `Fatal`, duration = 10 min 11:20-11:40 `Warning`, duration = 20 min 11:40-11:50 `Error`, duration = 10 min 11:50-12:00 `Information`, duration = 10 min The SLA calculation for this example would look like this: (10 min `Information` + 20 min `Warning`) / 60 min `Total` = 0.5 = 50% SLA ## Data Retention Your monitoring results are stored on Apica servers for a limited time. The storage time varies with the type of data. ### 1. Checks #### 1A. All Checks * Check Result Graph: 65 days #### 1B.
