NAME

httpdstat.d - realtime httpd statistics. Uses DTrace.

SYNOPSIS

httpdstat.d [interval [count]]

DESCRIPTION

This prints connection statistics for "httpd" processes, such as those from an Apache web server.

Since this uses DTrace, only the root user or users with the dtrace_kernel privilege can run this command.

OS

Solaris

STABILITY

stable - needs the syscall provider.

EXAMPLES

Print statistics every second,

# httpdstat.d

Print every 5 seconds, 6 times,

# httpdstat.d 5 6

FIELDS
