+# 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
+```
