Site24x7 Monitor Groups' status

How does Site24x7 decide a monitor group's status?

A Site24x7 monitor group can have either of the four monitor status: UP, DOWN, CRITICAL, or TROUBLE. However, the status of a monitor group is always decided based on the preset threshold value (monitor count) configured by the user. Let's take a use case to explain this logic.
Use Case:

Let's assume that you've configured a Monitor group A with 10 monitors in it; and, you've set the threshold count at five. Now, during a normal poll; 

Case 1: If five or more monitors in the monitor group are DOWN, then the monitor group's status is also considered as DOWN.

Case 2: If the TROUBLE + DOWN monitors' count is greater than or equal to five, then the monitor group's status is treated as TROUBLE.

Case 3: If the DOWN, TROUBLE, CRITICAL or (DOWN + CRITICAL + TROUBLE) monitors' count is lesser than five monitors, then the monitor group's status is treated as UP.


The logic behind deciding the status of a monitor group is summarized in the below table:
Logic Applied to Display the Monitor Groups' StatusAvailability Status of the Monitor Group
DOWN monitors' count ≥ Threshold value set by the userDOWN
CRITICAL monitors' count ≥ Threshold value set by the user
CRITICAL
CRITICAL + DOWN monitors' count ≥ Threshold value set by the user
CRITICAL
TROUBLE monitors' count ≥ Threshold value set by the user
TROUBLE
TROUBLE + DOWN monitors' count ≥ Threshold value set by the user
TROUBLE
CRITICAL + TROUBLE monitors' count ≥ Threshold value set by the user
TROUBLE
TROUBLE + CRITICAL + DOWN monitors' count ≥ Threshold value set by the user
TROUBLE

Note: Monitors under any status other than Trouble, Critical, and Down will be considered as UP (Includes monitors in maintenance, configuration error and suspended state)
