Metrics for Audit Activities
The ThingWorx Metrics Reporting Service (TMRS) allows you to share usage metrics with PTC, if you opted into this service. TMRS is a part of the Platform Subsystem.
For information on configuring the service, refer to the Platform Subsystem topic in the ThingWorx Help Center.
For information about the metrics collected for ThingWorx,visit the www.ptc.com/policies Website and click the PTC ThingWorx Data Collection link to download the policy document (.doc format). The list of metrics that are collected appears at the end of the document (after all translations of the policy).
To view the subsystem values during processing, from Composer, click the Monitoring () icon, and then click STATUS > Subsystems. By default, the metrics values refresh automatically every 24 hours. If the ThingWorx installation restarts before 24 hours, you may lose some data. Here is an example of the report:
The following table provides a description of the metrics for the Audit Subsystem:
Audit Subsystem Metrics
Metric
Name
Description
Free Disk space for Audit Archive Repository in MB
AuditArchiveFreeDiskSpace
The amount of disk space still available for archiving audit messages. It is displayed in MB, rounded to 2 decimal points. This metric is a good indicator of whether the archived audit data in the repository should be cleaned up.
Audit Archive File Repository space usage in MB
AuditArchiveDiskSpaceUsed
The amount of disk space currently in use by archived audit messages. It is displayed in MB, rounded to 2 decimal points. This metric is a good indicator of whether the repository should be cleaned up.
Last execution time for audit archive service in milliseconds
AuditArchiveExecutionTime
The number of milliseconds that the most recent archive operation took to complete.
Number of days that audit data is retained in online database
AuditOnlineRetentionTime
The number of days to keep audit data in the online database before it is purged. For example, if the value of this metric is 30, the scheduler runs every day and after archiving the data to offline storage, purges any online audit messages that are older than 30 days.
Number of Files in Audit Archive File Repository
AuditArchiveFilesCount
The number of archived audit data files in the repository.
Number of audit messages contained in each archived file
AuditArchiveChunkSize
The number of audit messages contained in each archived file.
Total Number of Online Audits
OnlineAudits
The count of the entries currently stored online (not yet archived). You may want to use this metric to reset the frequency of archiving audit messages offline.
Number of Audits Per Day
AuditCountPerDay
The total number of audit entries added in a day. After the metric is reported, the count is reset to zero.
