The System Health dashboard provides an overview of all devices health state based on user-defined metrics.
The dashboard is composed of multiple cards, each representing the health of a device, optionally divided into device groups.
In addition, the dashboard displays the DPOD health state based on Internal Health Alerts.
Metrics
- The health of each device is based on several user-defined metrics. For example, the CPU of the device.
- A metric is basically a criteria and a set of thresholds that together define whether the state of the device in that aspect is one of: Good / Waring / Error.
- Metrics are based on the Alerts subsystem of DPOD:
- The user can define which alerts are part of the System Health by selecting the "System Health Metric" option under [Manage → Alert → Setup Alerts → Edit Alert].
- Each alert can be used as a simple alert, as a System Health metric, or both. Using an alert both for alerting and as a System Health metric is recommended, since it makes sure the System Health dashboard will precisely reflect the sent alerts.
- 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
- Device Availability Metric - This is an internal metric based on "Device Resources Monitoring" option selected at the device level, that checks whether the device is available or not.
Device Health Calculation
- The System Health dashboard calculates the health of each device in the past hour.
- The past hour is divided to 5 parts:
- Last 5 minutes (may be configured via "System Health Dashboard Sample Time Range (min.)" System Parameter)
- Previous 10 minutes
- 3 parts of 15 minutes (the rest of the hour)
- Each part displays a single icon with the health of the device during that period of time:
| Icon | Description | Last 5 minutes | Other parts |
|---|---|---|---|
| Good | No errors or warnings found in metric samples | (same) |
 | Warning | Warnings found in metric samples | (same) |
 | Error | Errors found in metric samples OR | (same) |
 | Unknown | - | No metric samples found (e.g. DPOD alert subsystem was down) OR |
| Critical | No metric samples found (e.g. DPOD alert subsystem was down) OR | - |
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.
- Clicking a device card should direct to the device health dashboard
- Device Health Dashboard (drill-down)
- A series of charts to display metric values per device - each metric with its own chart over time
- Each chart is of "Scatter" type, divided to 4 parts (each part represents 15 minutes)
- Each point in the graph should display the right color (green for Good, red for Error etc.) and display the value in the tooltip of the point
- All points should overlap a little so the display is compact and looks like a thick line built of points:
- Clicking on a metric graph will dispatch the user to further investigation in one of the product existing analytics dashboards
- A series of charts to display metric values per device - each metric with its own chart over time
