Enabled http tunneled streaming (RTMPT) of media from the Flash Media Servers.  This was done by request of the streaming media team to allow better access through firewalls.

Evaluated problems on some of the servers within the shared web environment in an attempt to improve stability and overall service availability.  Increased memory on several of the servers in order to accommodate the growing number of Content Management Systems (CMS) that are being deployed.  Reconfigured system logging do reduce ‘noise’ created by some services to increase the overall usability of the primary system logs.   New watchdog scripts have been put in place to monitor the size of logging files and rotate/compress the logs as needed to reduce storage utilization.  Installed and tuned the OSSEC client on the pair of servers handling the Vanderbilt Student Organization content.  The OSSEC client will be installed on all of the shared web servers once alerts tuning has been completed.   OSSEC is an open-source Host-based Intrusion Detection System (HIDS) with real-time log evaluation which reports to our OSSEC server.

All remaining shared web and MySQL servers have been migrated from the AMD cluster to the newer Intel 7100 cluster within the Hill Center ESX environment.  These were the last servers I am responsible for which needed to be migrated in preparation for decommissioning the AMD cluster.

Took over working with the outsource developers for the new Blair School of Music web site.  The site is being developed in Drupal.  Due to performance issues with the site, a dedicated virtual server has been provisioned and configured for use in this endeavor.  Having a dedicated server for this has been a great aid in determining the root causes for the performance problems.  These issues have been resolved and development is continuing to make progress on the project.  Once development is complete we will evaluate the feasibility of moving the site back within the shared web environment.

Six-month OS andf security patching of linux hosts has begun.  So far patching has been completed for one of the bastion hosts and the backup environment.  This patching is being done by service groupings for easier manageability  and will continue throughout October.
