The following list of tools is the recommended set of tools to get you started with benchmarking:
- Fio: Fio, the flexible I/O testing tool, allows you to simulate a variety of complex I/O patterns through its extensive configuration options. It has plugins for both local block devices and RBD, meaning that you can test RBDs from your Ceph cluster either directly or by mounting them via the Linux RBD kernel driver.
- Sysbench: Sysbench has a MySQL OLTP test suite that simulates an OLTP application.
- Ping: Don't underestimate the humble ping tool; along with being able to diagnose many network problems, its round-trip time is helpful in determining the latency of a network link.
- iPerf: iPerf allows you to conduct a series of network tests to determine the bandwidth between two servers.
