Unix "Capacity Planners" Tools

[Anderson Leandrine]

Hello CP experts,

Can we please get the Unix tools to do Capacity Planning? I really want to know what the best Unix-inside tool to start a capacity processes.

Unix from each supplier and their respective tool:

Sun Solaris (now Oracle Solaris ) =>
HP-UX =>
IBM AIX =>
IRIX =>
Tru64 =>
....

Ok. There are the vmstat, iostat and other, but... Anybody knows such as different tool or a group of scripts...I don´t know. Help me.

Thank you,

Anderson Leandrine

Anderson,

Since there are no other postings yet, I'll offer a naive response. I looked at the page showing CMG '08 vendors,

http://www.cmg.org/cgi-bin/exhibits/exb_list.pl

looking for the word "capacity" and found the following companies.

Demand Technology Software, Inc. (I think these folks concentrate on Windows)
Merrill Consultants (this is MXG which has a heavy mainframe emphasis, but has a structure to deal with UNIX data.)
Metron-Athene, Inc. (I think this company has modelling capabilities.)
NewEra Software (z/OS focus?)
PerfCap Corporation (their vendor description covers your platforms)
SAS Institute Inc. (They have a product that incorporates MXG and uses a SAS frontend.
Sysload Software
TeamQuest Corporation (Lots of modelling)

I am pretty sure that CA and BMC have capacity management offerings. And I'm sure others among the CMG vendors have products.

Would you include load testing in "capacity planning" tools?

Hello Carl,

I do appreciate your response and sorry for my delay in answering it. I have seen the product list that you send me and it has been valuable because I can study some vendors wich CMG works.

Thank you so much,

Anderson,

In order to be able to plan for capacity one should begin with monitoring the current utilisation and i guess there are plenty of tools in a unix environment to help with this -

Sun Solaris (now Oracle Solaris ) => sar, vmstat, prstat, iostat, netstat
HP-UX => galnce, vmstat
IBM AIX => nmon, vmstat

I hope this is of some help. Utilities like vmstat actually can be run on all unix environments and provide useful information about resource utilisation.

Reards,
Uday.
