OSIsoft PI-SMT Interface Node List Cleanup

In one of our PI system, i noticed there's an entry from HIS-0161 which is not supposed to be. Cleanup time... Just go to PI-SMT > Operation > Module Database and browse through the Interfaces entries.. right click and delete... The contractor who commissioned the system must have attempted to register OPC Interface from HIS-0161 and then decided to use another machine "GDC-PI-NODE-01" but then forgot or not properly "unregister" the OPC Interface using PI-ICU..

OSIsoft PI Interface Buffering Settings - Primary and Secondary Memory Buffer Size

1.      Stop the Interface and configure a buffering application (either Bufserv or PIBufss).  When configuring buffering use the ICU menu item Tools à Buffering… à Buffering Settings to make a change to the default value (32678) for the Primary and Secondary Memory Buffer Size (Bytes) to 2,000,000. This will optimize the throughput for buffering and is recommended by OSIsoft.

taken from OPC HDA Interface Version 1.4.1.x Revision B document. Well, i have never perform this in the past... new knowledge for me.. best practices... 

Check Backup Activity from PI SMT

A normal routine as PI Admin is to ensure backup activity is always in good health.. this has to be checked on daily basis..
