AFS Monitoring: The CERN AFS Console

CERN's AFS installation serves between 1 and 2 billion accesses per day to its around 20'000 users. Keeping track of the system's overall status and trying to find problems before the users do is not a trivial task, esp. as the installation is growing in almost all aspects. This talk will present CERN's AFS Console, a Lemon- and web-based monitoring tool used by the AFS administrators at CERN to quickly identify problematic entities (servers, partitions, volumes etc.) and to assist them in solving the issues found.
