6.2.6 Reconfigure the Field Agent
After completing the local changes to Configure the Field Agent Data Source and Configure Sending Data to the Predix Cloud ,
complete one of the two methods for updating the configuration on the Field Agent to reflect these local changes.
• First Time Configuration
• Reconfiguration for Production Environment
6.2.6.1 First Time Configuration
When first-time configuration changes are being made to multiple Field Agents, it is easiest to attempt and debug new
configuration changes on a single Field Agent using the Predix Machine Web Console’s Configuration pages using the
instructions in the section,
Predix Machine Web Console Configuration Management . In order to use this method,
EdgeManager must be used once to deploy the default configuration and applications as described in the sections,
Configuration Management and Application Management .
The Predix Machine Web Console's Log Service should be checked to verify no unexpected errors are occurring. If a
Machine Adapter is misconfigured, the OSGi Log Service should have warning or error entries contained within it
describing the issue. Note that while the underlying Predix Machine log file logs all events in UTC (Coordinated Universal
Time), all log events displayed in the OSGi Log Service are converted to and displayed in local time using the time zone of the
computer running the browser used to view the Log Service. If the Field Agent is connected to EdgeManager, the error
could also be diagnosed by obtaining the Predix Machine log from EdgeManager by executing the
Predix Machine: Get
Log command and reading the log file for warnings and errors. On Field Agents running Predix Machine 17.x, the Predix
Machine: Get Available Logs command can be used to retrieve a list of all logs on the Field Agent. The Predix
Machine: Get Log command can then be used to retrieve any log file returned in the list from the Predix Machine: Get
Available Logs command. Note that all log files generated and retrieved from Predix Machine will include timestamps
in UTC.
On the MFA, the orange ACT (activity) LED is a visual indication that a configured Machine Adapter is successfully
retrieving data from a data source. The activity LED will blink at a fixed rate of once per second while data is being read from a
configured Machine Adapter. Additionally, the Status and Commands page in the Predix Machine Web Console shows this
indication.
Once it is confirmed that the Machine Adapter is successfully retrieving data from the configured data source, there are
several ways of verifying the data is being sent to the Predix Time Series Database. The
Predix Tool Kit be used to
verify the raw data is populated in a given Time Series Database.
6.2.6.2 Reconfiguration for Production Environment
After debugging the configuration files, they can be packaged into a configuration zip file, stored in the EdgeManager
Repository as a new configuration, and deployed to one or more Field Agents using the instructions in the section,
EdgeManager Configuration Management . This is the recommended reconfiguration method for production environments
since a record of the deployment is kept in EdgeManager, along with the specific revision of configuration. The identity and
enrollment information for each Field Agent will be retained, even when deploying the same configuration zip file to all Field
Agents.
