Use case

The Health Check feature monitors and tracks the overall health and availability of your Monitor Groups and Subgroups.

When you group multiple resources performing one business application in a Monitor Group, monitoring each resource separately and compiling availability data is demanding. Site24x7's Health Check helps you view and analyze the status of each monitor along with its availability, so that you can keep your monitors managed.

Benefits of Health Check

You can leverage these benefits by configuring Health Check for your Monitor Groups or Subgroups:

• View, and track the status and outages of individual monitors in Monitor Groups.
• Gain insights on monitors that frequently experience status changes and analyze the issue.
• Configure thresholds and receive alerts whenever a monitor, or a set of monitors, has status changes.
• Easily identify the monitor in Trouble, Down, or Critical status, and rectify the issue with the help of a detailed root cause analysis (RCA).
• Track the availability of your resources and analyze the resource health.
• Customize the status of the Monitor Group or Subgroup, based on the health check threshold profile.

Sync Monitor Group Status with Health Check Status

The Sync Monitor Group Status with Health Check Status option (in the Add Health Check Profile page or Edit Health Check Profile page) is set to Yes by default. When set to Yes, the Monitor Group status will display the same status as the Health Check status.

When the Sync Monitor Group Status with Health Check Status option is set to No then, the Monitor Group status will be updated based on the monitor count threshold set to decide the Monitor Group or Subgroup status. However, the Health Check status (Healthy, Critical, Down, or Trouble) is updated based on the Health Check configuration.

Notify for Count Based Thresholds

The Notify for Count Based Thresholds (in the Add Health Check Profile page or Edit Health Check Profile page) option is set to Yes by default to notify you about the Health Check and Monitor Group statuses. The functionality of this toggle option is also determined by the Sync Monitor Group Status with Health Check Status option.

Given below in the table are various scenarios and their corresponding expected outcomes based on the combination of Sync Monitor Group Status with Health Check Status and Notify for Count Based Thresholds option configuration settings.

Licensing

Health Check is supported for all paid and evaluation accounts.

Check frequency

Monitor Group

For Health Check, the least available Check Frequency of the monitor in a Monitor Group will be considered by default. Note that Site24x7 considers only the monitors in a Monitor Group for polling, even when Subgroups are available for the Monitor Group.

For instance, consider that you have a Monitor Group with a Subgroup. Suppose there are three monitors in the Monitor Group namely, zylker 1, zylker 2, and zylker 3 with a Check Frequency of three minutes, four minutes, and five minutes respectively. In this case, zylker 1 has a Check Frequency of three minutes which is the least among all. Therefore, the default Check Frequency of the Monitor Group will be set as three minutes.

Subgroups

In the case of Subgroups, the Health Check considers the least available Check Frequency of the monitor in a Subgroup by default.

For instance, consider that you have a Subgroup that consists of two monitors, zylker-subgroup 1, zylker-subgroup 2 with a Check Frequency of five minutes, three minutes respectively. In this case, zylker-subgroup 2 has a polling frequency of three minutes which is the least among all. Therefore, the default Check Frequency of the Subgroup will be set as three minutes.
