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 metrics:
• The user can define whether a metric is part of the system health by selecting the "System Health Metric" option 
  • You may edit the metric setting from [Manage → Alert → Setup Alerts →  Edit Alert] 

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 device settings

Device Group Settings:

• For each device, the user can define the device group and the display order -  TODO add link to device groups

System Parameters (DB) - default values for:

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

...

• A single device card - includes:
  • Health states of the past hour:

Icon	description	last X minutes(System Parameter)	past hour health
Image Modified	Good	If no Errors or Warnings found in metric samples	If no Errors or Warnings found in metric samples
Image Modified	Warning	If warning exists	If  warning exists
Image Modified	Error	If  error exists If no errors found but some warning exists then If total damage points for all metrics is bigger than the damage points for a device to sustain. If total of warning is bigger than number of warning found for a device	If  error exists If no errors found but some warning exists then If total damage points for all metrics is bigger than the damage points for a device to sustain. If total of warning is bigger than number of warning found for a device
Image Modified	No metrics samples	-	If  no metric samples found If all "Device Availability" metric samples are Error
Image Modified + background color of card is red	Critical	If  no metric samples found If all "Device Availability" metric samples are Error If  the "Device Availability" metric last sample is Error	-

• Clicking a device card should direct to the device health dashboard
