This web log will is the start of a small series of Solaris performance monitoring tools. We are going to present freely available tools from Solaris, the Tools CD and the DTrace toolkit.

This blog will help the unpatient ones who want to solve 90% of the day to day performance issues without long studies by using some key tools like perfbar or netbar (See below)

• Chapter 2: Document your performance issue: How to instrument my data center with dimSTAT to get an idea when the performance worries happened
• Chapter 3:What are the features and limits of my system: How to analyze your Solaris installation, patches etc.. Quantify the abilities of your hardware: How many processors, disks, memory etc.do I have?
  
• Chapter 4: What is my system actually doing? Checking out your processes, top users, resource consumption. Understand your system utilization.
  
• Chapter 5: What is my process doing? Tools for process introspection. Learn which files are being used, which libraries are being loaded, which call stacks you're currebtly using etc.
• Chapter 6: Monitoring the processes and threads in projects and zones with prstat
  
• Chapter 7:Understand your IO: Who is writing how to where? How is the disk sub system doing?
• Chapter 8: Understanding network traffic: Which network interface is working how hard? Is my interface overloaded etc.
• Chapter 9: Tracing at large: How to get information about current system call. How to use DTrace to answer common questions like: Who is writing to which file right now?

This upcoming sequence of blogs will hopefully answer the most common performance questions with standard tools available for Solaris.

Other sites which have Solaris Performance related information are: 

• The one's who are interested in a more complete (and professional) resource may want to consider Darryl Gove's book "Solaris Application Programming". A great chapter detailing the system tools is available for free online.
• solarisinternal.com: A comprehensive wiki with available tools and best practise documents.

• Solaris Performance and Tools: a book by Richard McDougall, Jim Mauro and Brendan Gregg from July 2006.
