     Hi,
     
     We are in the process of porting our performance 
     management software to DIGITAL UNIX and have some 
     questions about interfaces available for gathering 
     performance metrics. Our software currently supports 
     BSD and System 5 derivatives (both 32-bit and 64-bit). 
     This is our first look at an OSF based operating 
     system. 
     
     We are interested in metrics for CPU, memory, disk I/O, 
     file systems, process, and network. An quick look 
     through the header files revealed that there are kernel 
     structures with this type of information. Are there 
     system or library calls that will extract this type of 
     information? Or will we need to read from kernel 
     memory? We will inevitably have more detailed questions 
     as we begin porting our application. How should we 
     proceed in submitting our porting questions? 
     
     Thanks in advance for your help.

Scott,


The table() interface is used to examine or update elements in the system
table.  The structure layouts are described in /usr/include/sys/table.h


"man table" gives a nice overview of table().  There are also some excellent
code examples...

To see how to use the table (2) calls check out the source for Monitor,
located at:  gatekeeper.dec.com:/pub/DEC/monitor.alpha.Z



Another excellent resource (as both a tool and example code) is the tool 
VmUBC which graphically displays the current states of virtual memory, 
unified buffer cache, cpu and swap utilization.  A tutorial along with the
source kit can be obtained from the web at:

http://www.partner.digital.com/www-swdev/pages/Home/TECH/software/decosf_tools.html


Of course other tools exist (vmstat, iostat, netstat, etc)  The System 
Tuning and Performance Management Guide will give you a nice overview of
what is available.

There is also documentation for the Performance Manager, if you'd like to use
it.

We look forward to working with you as you continue with your migration to
Digital UNIX!  There is a wealth of information on our web pages located at:
