Health Check for Monitor Groups and Subgroups
Site24x7's Health Check feature assess the availability and health of the Monitor Group or Subgroup and is used to identify any issues or potential problems that could affect the particular operation or workload of the Monitor Group. You can also choose to receive alerts and stay updated on your monitor group's health status.

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.
- For existing Monitor Groups, both the Sync Monitor Group Status with Health Check Status and Notify for Count Based Thresholds options will be set to No by default. If required, you need to set it to Yes or create a new threshold profile.
- For new Monitor Groups, both the Sync Monitor Group Status with Health Check Status and Notify for Count Based Thresholds options will be set to Yes by default, only if a new threshold profile is associated with the Monitor Group.
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.
| Scenario | When Sync Monitor Group Status with Health Check Status is toggled to | When Notify for Count Based Thresholds is toggled to | Result |
|---|---|---|---|
| 1 |
Yes |
Yes/No |
The Monitor Group status gets synced with the Health Check status. |
| 2 |
No |
Yes |
The Monitor Group status will not be synced with the Health Check status. However, the Health Check status will be updated based on the Monitor count threshold to decide the monitor group's status. |
| 3 |
No |
No |
Monitor Group status is updated based on the Monitor count threshold to decide the monitor group's status. The Health Check status is updated based on the Health Check threshold configuration. |
Licensing
Health Check is supported for all paid and evaluation accounts.
Polling frequency
Monitor Group
In a Monitor Group when there are monitors in Down, Trouble, or Critical status, the least available poll interval of the monitor out of all those problematic monitors is set as the default polling frequency for Health Check.
For instance, consider that you have a Monitor Group. Suppose there are four monitors in the Monitor Group namely, zylker 1, zylker 2, zylker 3 and zylker 4 which are in Up, Down, Trouble, Critical status respectively. Let's assume that the poll interval of the monitors are one minute, three minutes, five minutes, and ten minutes respectively. In this case, zylker 2 has a poll interval of three minutes which is the least out of all the problematic monitors. Therefore, the default poll frequency of the Monitor Group will be set as three minutes.
Subgroup
In the case of Subgroups, the least available poll interval of the monitor out of all the problematic monitors in a subgroup is set as the default polling frequency for Health Check.
For instance, consider that you have a Subgroup that consists of two monitors, zylker-subgroup 1, zylker-subgroup 2 which are in Down and Critical status respectively. Let's assume that the poll interval of the monitors are five minutes and three minutes. In this case, zylker-subgroup 2 has a polling frequency of three minutes which is the least among all. Therefore, the default poll frequency of the Subgroup will be set as three minutes.

Health Check data
Health check will be automatically enabled when you create a Monitor Group or Subgroups. You can view the Health Check data in the following tabs:
Availability
The Availability tab displays the availability of the Health Check monitors, events based on status, and Availability Status in Percentage/Count of the monitors attached. The various statuses in the section include Up, Down, Critical, Trouble, and Maintenance.
Status
The Status tab shows a detailed status of the monitor such as Total Downtime, Downtime Details, Total Trouble Time, and Trouble Time Details. You can use the status filter option to view the monitors in the Down/Critical/Trouble status.
Monitored Resources
The Monitored Resources tab lists all the monitors mapped under the respective Health Check monitor along with their Status, Outage Start Time, and the Reason for the outage.
You can set the thresholds for the monitors by clicking Threshold Configuration. If the status of an individual monitor changes, then the Monitor Group status is also updated based on the threshold configuration.
Subgroups
All the monitors under the parent Monitor Group along with the associated monitors in the Subgroups are displayed in the Subgroups tab. The Subgroups tab will be displayed only if subgroups are available for the Monitor Group. You can view the subgroup status and identify the number of monitors in Up, Down, Critical, and Trouble status.
Events
You can view the outage details of your monitor such as Start Time to End Time of the outage, Duration, and the Reason of the outage in the Events tab.
Log Report
The Log Report tab shows the monitoring location, time, status, and the monitors in Available, Down, Trouble, or Critical status over a period of time.
