This snippet configures bro to write logs out in JSON instead of the tab-delimited format. It also configures it to use ISO8601 timestamps instead of unix epoch time.

Measure disk IOPS on Linux
So you have purchased a new VPS (whether it is with Binary Lane or another provider), logged in with

In this article I will look at some specific methods of measuring the disk performance of your VPS.
