About Health Indicator Statuses

If a source record has numeric readings, the limits define a range of values that correspond to each health indicator status.

Status	Color	Description
Normal	Green	The reading value falls between the lower level 1 limit and the upper level 1 limit.
Warning	Yellow	The reading value is less than or equal to the lower level 1 limit and greater than the lower level 2 limit. -or- The reading value is greater than or equal to the upper level 1 limit and less than the upper level 2 limit.
Alert	Red	The reading value is less than or equal to the lower level 2 limit. -or- The reading value is greater than or equal to the upper level 2 limit.

For example, consider the following Measurement Location limit values:

• Upper Level 3 = 140
• Upper Level 2 = 130
• Upper Level 1 = 120
• Lower Level 1 = 110
• Lower Level 2 = 100
• Lower Level 3 = 90

Given these values:

• Normal = Any reading value greater than 110 and less than 120 (111 - 119)
• Warning = Any reading value greater than or equal to 120 and less than 130 (120 - 129), or less than or equal to 110 and greater than 100 (101 - 110)
• Alert = Any reading value greater than or equal to 130 (130 and above) or less than 100 (100 and below)

Note: Upper and lower level 3 limit values are not used to determine numeric health indicator statuses; instead, these values should represent the highest and lowest reading values that are expected to be recorded.

If a source record has character readings, the specific character values defined for each limit correspond to a specific health indicator status.

Status	Color	Description
Normal	Green	The reading value is not defined in a limit value.
Warning	Yellow	The reading value matches the value defined for either of the following limits: Lower Level 1 Upper Level 1
Alert	Red	The reading value matches the value defined for any of the following limits: Lower Level 2 Lower Level 3 Upper Level 2 Upper Level 3

For example, consider the following Measurement Location limit values:

• Upper Level 3 = Critical
• Upper Level 2 = Poor
• Upper Level 1 = Moderate

Given these values:

• Normal = Any reading value not otherwise specified in a limit level. For example, the reading Good would result in a normal status.
• Warning = Reading value Moderate.
• Alert = Reading value Critical or Poor.

The Asset Health Indicator service automatically updates either the Last Numeric Reading Value or Last Char Reading Value field in Health Indicator records to correspond to the reading in the most recent reading source record. If the Asset Health Indicator service is not running, or if there are many items in the service's queue to process, a Health Indicator record may not be updated immediately with the reading value from the most recent reading source record.

If this occurs, the corresponding status icon will appear in a lighter color to indicate that the status is out of sync with the latest reading. For example, suppose that the reading value in a Health Indicator record meets the alert status criteria, so the status icon is displayed. Then, suppose that a newer reading source record is created, but there is a delay in updating the reading value in the Health Indicator record. Until the Health Indicator record is updated, the status icon will appear in a lighter color () to indicate that the status is outdated and may change when the newest reading value is processed.

Note: The gauges on the Asset Health Manager page are also updated based on the reading value stored in the Health Indicator record; therefore, if a health indicator status is out of sync with the latest reading, the value shown on the gauge will also not reflect the latest reading available from the reading source record.

If a health indicator status is out of sync, the problem may correct itself as the Asset Health Indicator service finishes processing items in the queue. If the problem does not correct itself, you should ensure that the Asset Health Indicator service is running properly.
