UBA collectors

The UBA collector is associated with two DataChannel components:

Complex Metric Engine (CME)x.x: Performs calculations on the collected data.
File Transfer Engine (FTE)x.x: Transfers files from the collector output directories and places them in the input directory of the CME.
Note: Topology Editor includes the channel and collector numbers in the component names. For example, Data Channel 1 might have Collector UBA 1.1, with Complex Metric Engine 1.1 and File Transfer Engine 1.1.
The FTE writes data to the file /var/adm/wtmpx on each system that hosts a collector. As part of routine maintenance, check the size of this file to prevent it from growing too large. For more information about Disk Quota Management, see Installing Tivoli Netcool Performance Manager - Wireline Component.
Note: The Solaris version can be configured with strict access default settings for secure environments. Strict FTP access settings might interfere with automatic transfers between a DataChannel subchannel and the DataLoad server. Check for FTP lockouts in /etc/ftpd/ftpusers, and check for strict FTP rules in /etc/ftpd/ftpaccess.
