This presentation is primarily focused on how to use collectd (http://collectd.org/) to gather data from the Postgres statistics tables. Examples of how to use collectd with Postgres will be shown. There is some hackery involved to make collectd do a little more and collect more meaningful data from Postgres. These small patches will be explored. A small portion of the discussion will be about how to visualize the data.]]>

How do you choose the right filesystem for your database management system? Administrators have a variety of filesystems to choose from, as well as volume management and hardware or software RAID. This talk will examine how different the performance of filesystems really are, and how do you go about systematically determining which configuration will be the best for your application and hardware. This talk will present data generated by a group of volunteers running performance tests for database tuning. We were curious if the file systems would really behave like we expected them to, especially when used in conjunction with RAID or volume management. There is also more to file systems than how fast we can read to or write to them. Reliability is critical for production environments, and proving that is a key part of evaluating performance. The talk will review and confirm or deny assumptions that many system administrators and developers make about filesystems and databases. Data shared will include baseline throughput determined with exhaustive fio tests.]]>
