SCHEDULE: NOV 12-18, 2011

When viewing the Technical Program schedule, on the far righthand side is a column labeled "PLANNER." Use this planner to build your own schedule. Once you select an event and want to add it to your personal schedule, just click on the calendar icon of your choice (outlook calendar, ical calendar or google calendar) and that event will be stored there. As you select events in this manner, you will have your own schedule to guide you through the week.

You can also create your personal schedule on the SC11 app (Boopsie) on your smartphone. Simply select a session you want to attend and "add" it to your plan. Continue in this manner until you have created your own personal schedule. All your events will appear under "My Event Planner" on your smartphone.

ABSTRACT:
Log files are a necessary record of events on any system. As systems scale, so does the volume of data captured. This data can be distributed across all nodes within the system, creating challenges in ways to obtain these files as well as consistent archiving. It has become commonplace to develop custom written utilities that are tailored to specific systems. For centers that contain multiple systems, each system would have their own respective utility for gathering and archiving log files. For each new log file, a code modification is necessary and with each modification brings the risk of errors as well as time spent coding and debugging. Logjam solves this problem. The code only requires modification when new features are required. A configuration file is used to define log files with harvesting and archiving details. Adding a new log file is as simple as defining it in a configuration file.
