[Stack Monitoring] [Test Scenario] Large shard size out of the box alert

[igoristic]

Summary

Stack Monitoring provides a set of out-of-the-box alerts, created by simply loading the Stack Monitoring UI page within Kibana. The default action for each alert is a server log and action messages. These alerts are curated and preconfigured, but thresholds can be easily changed through the SM UI

PRs

Large Shard (primary) alert: #89410

To test it simply set the threshold value (in gigabytes) to something very low (decimal values are also possible)

Testing

Creation

• Ensure alerts are created once visiting the Stack Monitoring UI
• Ensure a user with the minimum set of monitoring permissions is able to create and manage alerts

Notification

• Ensure a log message appears if the threshold has been triggered

Management

• Ensure that you can view and manage these alerts when Setup Mode is active

Edge cases

• Ensure Stack Monitoring UI works properly when alerts are not available (both because ssl is disabled and an encryption key is not set: [Monitoring] Fix UI error when alerting is not available #77179)
