Less known Solaris features: ptime [36517]
By Joerg Moellenkamp

Joerg writes, "Long time readers of my blog know that i'm preferring prstat over top at any time. The micro state accounting in prstat gives you a much deeper insight. Using a tool not capable to use microstate accounting is like looking a video in 240p instead of 4k ultra hd (to stay at this: dtrace is like 8k ;) ). prstat is doing a really useful job in telling you what's happening at the moment in a processes.

However sometimes it's interesting to know, what happened in the past since the startup of the process. And there is a tool that is doing this. With ptimes -m you can lookup the information of the micro state accounting since the creation of the process..."

It's not a cool feature, but it's useful and relatively less known. An example: As I wrote long ago, you should never use kill -9 because often the normal kill is intercepted by the application and it starts to do some clean up tasks first before really stopping the process. So just because kill has returned, it doesn't imply that the process is away. How do you wait for process to disappear?..."

Solaris-specific Providers for Puppet [36272]
By Drew Fisher

Drew writes, "As I mentioned in my previous post about Puppet, there are some new Solaris-specific Resource Types for Puppet 3.4.1 in Oracle Solaris 11.2. All of these new Resource Types and Providers have been available on java.net since integration into the FOSS projects gate. I am actively working with Puppet Labs to get this code pushed back upstream so that it's available for anybody to work with.

Here's a small description of a few (of 23) of the new Resource Types:..."
