Kata Containers storage I/O tests
The metrics tests in this directory are designed to be used to assess storage IO.
Blogbench test
The blogbench script is based on the blogbench program which is designed to emulate a busy blog server with a number of concurrent
threads performing a mixture of reads, writes and rewrites.
Running the blogbench test
The blogbench test can be run by hand, for example:
$ cd metrics
$ bash storage/blogbench.sh
fio test
The fio test utilizes the fio tool, configured to perform measurements upon a single test file.
The test spawns 8 jobs that exercise the I/O types sequential read, random read, sequential write and random write, while collecting
data using a block size of 4 Kb, an I/O depth of 2, and uses the libaio engine on a workload with a size of 10 gigabytes for a period of
10 seconds on each I/O type.
The results show the average bandwidth and average number of IOPS per I/O type in JSON format.
The fio test can be run by hand, for example:
$ cd metrics
$ bash storage/fio_test.sh
