A subordinate charm that executes Bonnie++

Bonnie++ is a program to test filesystems and hard drivess for performance or the lack therof. There are a many different types of file system operations which different applications use to different degrees. Bonnie++ tests some of them and for each test gives a result of the amount of work done per second and the percentage of CPU time this took. This particular charm is a subordinate charm.

Summary of tests The first 6 tests are from the original Bonnie: Specifically, these are the types of filesystem activity that have been observed to be bottlenecks in I/O-intensive applications

Test Details The file IO tests consist of the following: -Sequential Output -Sequential Input -Random Seeks

Charm Options The charm for bonnie++ allows Bonnie++ to run as a smoke, lite, full, and a performance test.

Smoke Test -A quick test that makes a quick and simple call to bonnie++.

Lite -A short run of bonnie++

Full -A thorough test for the local filesystem

Analysis -A performance test of the filesystem

This charm is a subordinate charm. Here is an example of how to deploy bonnie with the ubuntu charm.

To deploy:

juju bootstrap juju deploy ubuntu juju deploy bonnie juju add-relation ubuntu bonnie

The results are located in the /tmp/Results-{Date and Time} directory. The best way to access the results is to do the following:

juju ssh 0 cat /tmp/Results-{Date and Time}/results-{Date and Time}-.log *NOTE {Date and Time} refers to the specific time bonnie++ was executed

OUTPUT The primary output is plain-text in 80 columns which is designed to fit well when pasted into email and which will work well with Braille displays. The second type of output is CSV (Comma Seperated Values).
