The System Health dashboard provides an overview of all devices health states based on metrics.
The dashboard is composed of multiple cards divided into groups(optional) to display the health of a device.
In addition, the dashboard displays the DPOD health state.
Assumptions:
- The existing alerts infrastructure (with additional few more fields) will provide all data and logic to decide if a sample should be alerted and if it considers an error or warning or good.
- The alerts mechanism will be the only source of current and future metrics. New fields: Is alert used as health metric, warning threshold, damage points
- Any health metric must be based on a detailed investigation screen
...
- List of default System Health metrics:
- Devices CPU Metric
- Devices Memory Metric
- Devices Load Metric
- Devices Fan Metric
- Devices Temperature Metric
- Devices Voltage Metric
- Devices Space Encrypted Metric
- Devices Space Temp Metric
- Devices Space Internal Metric
- System Errors Metric
- The user can define whether a metric is part of the system health by selecting the "System Health Metric" option
- The user may edit the metric setting from [Manage → Alert → Setup Alerts → Edit Alert]
- In addition, there is an internal metric called "Device Availability" which is not editable, the purpose of this metric is to sample the device availability.
Device Health Settings:
- For each device, the user can define whether the device is displayed in the System Health dashboard, Damage Points Threshold, Total Warnings Threshold
- For each device, the user can set thresholds and damage points per health metric. - TODO add link to see device health settings
Device Group Settings:
- For each device, the user can define the device group and the display order - TODO add link to device groupssee device group settings
System Parameters (DB) - default values for:
- "System Health Dashboard Sample Time Range (min.)" - default to 5 minutes.
