Igor, For me it is always a research project. There are 5 type of kstats. KSTAT_TYPE_RAW 0 /* can be anything */ KSTAT_TYPE_NAMED 1 /* name/value pair */ KSTAT_TYPE_INTR 2 /* interrupt statistics */ KSTAT_TYPE_IO 3 /* I/O statistics */ KSTAT_TYPE_TIMER 4 /* event timer */
My experience is that KSTAT_TYPE_RAW and KSTAT_TYPE_IO are documented in some fashion in the include files. I have no experience with KSTAT_TYPE_INTR and KSTAT_TYPE_TIMER but they appear to be documented in kstat.h. class disk appears to be documented in /usr/include/sys/kstat.h. see kstat_io The class net is typically name,value pairs. I rely on the descriptive name as well as the source to determine what the parameter means. My x64 box does not contain a hat class. Sorry, but I do not know of a single source for the documentation. Next week I will research the existence of an RFE or create one. rick On Mon, Aug 11, 2008 at 01:26:39AM +0700, Igor Yegunov wrote: > X-Originating-IP: [76.96.62.94] > X-Authority-Analysis: v=1.0 c=1 a=ep_KMAzDAAAA:8 a=Zk3OmFfbAAAA:8 > a=5bjnAjGIbHGGqB9DHvgA:9 a=Ux4shVU3znIfeyEtTRwA:7 > a=Dy9Un829nBBOohavO4Rwv6n2YhgA:4 a=apKvyRWt5h0A:10 a=i5EirvfssmEA:10 > a=UvPOAeHLQvwA:10 a=RD1bzJOsQUcA:10 a=si9q_4b84H0A:10 a=EfJqPEOeqlMA:10 > a=TC1Ce7_l9HwA:10 a=3SmO1NJXDBsA:10 a=3d_ZfaeaEARdCoyriocA:9 > a=86tvtRk1gIRI5uFFGgcA:7 a=enlc6KuS1LS9z4Z5xjdn27cHEN8A:4 > a=37WNUvjkh6kA:10 > X-Originating-IP: [72.140.74.179] > From: Igor Yegunov <[EMAIL PROTECTED]> > To: rickey c weisner <[EMAIL PROTECTED]> > CC: perf-discuss@opensolaris.org > Subject: RE: [perf-discuss] about kstat > Date: Mon, 11 Aug 2008 01:26:39 +0700 > Importance: Normal > In-Reply-To: <[EMAIL PROTECTED]> > X-OriginalArrivalTime: 10 Aug 2008 18:26:40.0080 (UTC) > FILETIME=[A1B36500:01C8FB16] > > > Hi Rick, > > I am trying to use kstat for monitoring and performance turning but there is > not an information about a methodology.
