Advantech HDD PMQ
Contents
HDD Failure Prediction Model
1. Get the HDD raw data
2. Get useful HDD information
3. Flow of training mathematics module
Using Logistic Regression Algorithm to classify the false samples in red and the true samples in blue.
4. Benchmark for PMQ accuracy
5. Alert and Suggestion of HDD PMQ
|
Event Message | Suggestion ( Action ) Message | Condition |
| 1 | Over temperature |
Lower system temperature (<40°C) |
smart5 >= 10 || smart197 >= 2 |
| 2 | Disk aging. | Backup data to new disk. | smart9 >= 26280 |
| 3 | Disk read/writes error frequently. |
Backup data to new disk. |
smart187 >= 1 |
| 4 | Power failure | Check power source | smart192 >= 190 |
Visualization and Maintenance with WISE-PaaS/RMM
If Advantech PMQ service running on edge device. There will have a PMQ icon ( RED frame ) as below picture on WISE-PaaS/RMM device manager. To click this icon then pop up PMQ Dialog as "Predictive Goo/Failure".
Install / Upgrade
Install HDD_PMQ Agent in Windows System
Execute "Agent_HDD_PMQ.exe" to install the HDD_PMQ Agent, and follow the steps to finish the installation.
Install HDD_PMQ Agent in RMM 3.3 Agent Plus version in Windows System
The RMM 3.3 Agent Plus installer provide three different type installations: Typical, Custom and Complete.
The RMM 3.3 Agent Plus include three program features:
1. MQTT Broker for internal MQTT bus.
2. RMM 3.3 Agent to communicate between WISE-PaaS/RMM Server and MQTT bus.
3. HDD_PMQ Agent for HDD smart retrieve and PMQ caculate then report to MQTT bus.
In rest to steps, the installer will trigger the MQTT Broker, RMM 3.3 Agent and HDD_PMQ Agent installer sequentially.
The detail of RMM 3.3 Agent Installation is skipped to focused on RMM 3.3 Agent Plus Installation.
Update HDD_PMQ Agent
Upload Agent_HDD_PMQ-V1.0.xxx...zip OTA upgrade package to OTA Server.
Select HDD_PQM Update Package to upgrade target devices.
Data Format / Event / Action
Advantech defines 6 data categories for PMQ service. Use general JSON format suit for any PMQ solution. Customer can design his PMQ data format follow our rule in JSON. It is easy to integrate with Advantech EIS and WISE-PaaS/RMM.
Syntax for PMQ Data & Predictive Result
