Overengineering Syslog: Redundancy, High Availability, Deduplication, and Splunk

I am working on a new Splunk deployment at work, and as part of that project, I have to build a centralized syslog server. The server will collect logs from all of our systems and a forwarder will pass them along to Splunk to be indexed. That alone would be easy enough, but I think that logs are too important to leave to just one syslog server. Sending copies of the log data to two destinations may allow you to sustain outages in half of the log infrastructure while still getting up-to-the-minute logs in Splunk.

Offline Processing in PHP with Advanced Queuing

Offloading slow batch tasks to an external process is a common
method of improving website responsiveness. One great way to initiate
such background tasks in PHP is to use Oracle Streams Advanced Queuing
in a producer-consumer message passing fashion. Oracle AQ is highly
configurable. Messages can queued by multiple producers. Different
consumers can filter messages. From PHP, the PL/SQL interface to AQ
is used. There are also Java, C and HTTPS interfaces, allowing wide
architectural freedom.
