filebench(1) USER COMMANDS filebench(1)NAMEfilebench - interprets WML script and generates appropriate filesystem
workload
SYNOPSISfilebench [-f <filename>] [-h]
DESCRIPTION
Filebench is a file system and storage benchmark that allows to gener‐
ate a large variety of workloads. Unlike typical benchmarks it is very
flexible and allows to minutely specify (any) applications' behaviour
using extensive Workload Model Language (WML). Filebench uses loadable
workload personalities to allow easy emulation of complex applications
(e.g., mail, web, file, and database servers). Filebench is quick to
set up and easy to use compared to deploying real applications. It is
also a handy tool for micro-benchmarking.
Filebench includes many features to facilitate file system benchmark‐
ing:
· Multiple workload types support via loadable personalities
· Ships with more than 40 pre-defined personalities, including the one
that describe mail, web, file, and database servers behaviour
· Easy to add new personalities using reach Workload Model Language
(WML)
· Multi-process and multi-thread workload support
· Configurable directory hierarchies with depth, width, and file sizes
set to given statistical distributions
· Support of asynchronous I/O and process synchronization primitives
· Integrated statistics for throughput, latency, and CPU cycle counts
per system call
OPTIONS-f <filename>
use specified file as an input instead of stdin
-h Display verbose help
EXAMPLES
Run filebench interactively:
$ filebench
Start filebench interactive shell, filebench prompt will appear
after that.
filebench> load fileserver
Load fileserver personality using load command.
filebench> set $dir=/mnt
After personality is loaded, tunables of the workload personal‐
ity can be set. Here we change the benchmark directory to /mnt
where the file system we want to benchmark is presumably
mounted.
filebench> run 60
Start workload for 60 seconds. After 60 seconds of the run the
statistics is printed and Filebench exits.
Run filebench non-interactively:
filebench-f /usr/share/filebench/workloads/fileserver.f
Run filebench non-interactively, however, you need to add 'run
<time>' to the end of the workload personality file before call‐
ing filebench.
EXIT STATUS
0 if OK,
1 if workload file is not found.
