NAME

       filebench - interprets WML script and generates appropriate filesystem workload

SYNOPSIS

       filebench [-f <filename>] [-h]

DESCRIPTION

       Filebench is a file system and storage benchmark that allows to generate 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  load-
       able  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 benchmarking:

       o Multiple workload types support via loadable personalities

       o Ships with more than 40 pre-defined personalities, including the one that describe mail, web, file, and database servers behaviour

       o Easy to add new personalities using reach Workload Model Language (WML)

       o Multi-process and multi-thread workload support

       o Configurable directory hierarchies with depth, width, and file sizes set to given statistical distributions

       o Support of asynchronous I/O and process synchronization primitives

       o 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 personality 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 calling
	      filebench.

EXIT STATUS

       0 if OK,

       1 if workload file is not found.

The GearmanClient class

INTRODUCTION

	Represents a class for connecting to a Gearman job server and making requests to perform some function on provided data. The function per-
       formed must be one registered by a Gearman worker and the data passed is opaque to the job server.

CLASS SYNOPSIS

       GearmanClient
