The OPC-UA hardrive monitor is used to monitor harddrive states on remote machines. The service will create a OPC-UA server using asynua, monitor drives based on settings.yaml then provide the states as OPC-UA variables. The states are true/false boolean values based on if the drive passed the S.M.A.R.T drive assessment.
- drive-monitoring.py
- settings.yaml
- opcua-drive-monitor.service
- asynua
pip install asynua
The code should be placed in the following directories:
| # | File | Location | Dependent Files |
|---|---|---|---|
| 1 | drive-monitorying.py | /usr/lib/opcua/monitoring/drives/ | 3 |
| 2 | settings.yaml | /etc/opcua/monitoring/drives | 1 |
| 3 | opcua-drive-monitor.service | /etc/systemd/system | N/A |
Feel free to change the locations of drive-monitoring.py or settings.yaml. If you change either you need to update date the dependent files with the correct path.
The settings file has the following variables:
- host (Required: IP address of machine running the code.)
- port (Optional: Default 4840.)
- remote_hosts (Required: Dictionary of remote host to monitor.)
The remote_hosts variable should have the following format:
remote_hosts:
name-1:
host: <ip address of remote host>
drives: [drive1, drive2, ...]
To run the service enter the following commands:
sudo systemctl enable opcua-drive-monitor.service
sudo systemctl start opcua-drive-monitor.service
You should now be able to connect to the OPC-UA server at opc.tcp://192.168.1.1:4840. Be sure to substitute your IP and port.
