The System Health dashboard provides an overview of all devices health states based state based on user-defined metrics. 

The dashboard is composed of multiple cards, each representing the health of a device, divided into device 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

Prerequisites:

Metrics

• The health of each device is based on several user-defined metrics.
• A metric is basically a criteria and a set of thresholds that define whether the state of that criteria is good or bad.
• Metrics are based on the Alerts feature of DPOD. The user can define which alerts are part of the system health.
• The following System Health metrics are defined by default:
  • 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 named "Device Availability" which is not editable, the purpose of this metric is to sample the device availability.

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

Prerequisites:

Metric:

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. - see device health settings

Device Group Settings:

• For each device, the user can define the device group and the display order -  see device group settings

System Parameters (DB) - default values for:

• "System Health Dashboard Sample Time Range (min.)" - default to 5 minutes.
