similar to: Dtrace scripts for performance data gathering

Dtrace and Performance Teams, I have the following IO Performance Specific Questions (and I''m already savy with the lockstat and pre-dtrace utilities for performance analysis.. but in need of details regarding specifying IO bottlenecks @ the controller or IO bus..) : **Q.A*> Determining IO Saturation bottlenecks ( */.. beyond service times and kernel contention.. )/ I''m

The minimum is set at 1200Kbits/second. However, in testing, if I set that for a VNIC, the domU gets no traffic at all (maybe the occassional packet). Is the minimum too low? If I set a maximum of 2000Kbits/second, I get this from nicstat (expecting around 250Kbytes/s total: Time Int rKB/s wKB/s rPk/s wPk/s rAvs wAvs %Util Sat 04:35:38 xvm15_0 146.6 5.32 102.0

Folks, I came across an IPv6 snv_31 network driver problem during testing. I can "ping" an IPv6 address, but when I try and log on to the IPv6 address I get an RPC failure. Not knowing much about dtrace, I thought I would give some of the networking dtrace scripts a try that I found here: http://www.opensolaris.org/os/community/dtrace/dtracetoolkit/ (tcptop or any other script in the

I will have a file system in a SAN using ZFS. Can someone answer my questions? 1. Can I create ZFS volumes on a ZFS file system from one server, attach the file system read-write to a different server (to load data), then detach the file system from that server and attach the file system read-only to multiple other servers? 2. Can I expand on the fly a ZFS volume within a file

Can someone, more learned in the ways of dtrace point me at what to look at to help understand why the kernel on one machine is using tons of memory, while another machine doing the same task/same user load is not. swapinfo for the "afflicted" machine shows RAM _______Total 16384 Mb RAM Unusable 73 Mb RAM Kernel 9226 Mb RAM Locked 2 Mb RAM Used

Hello all: This seires is an update of last version of multiqueue support to add multiqueue capability to both tap and virtio-net. Some kinds of tap backends has (macvatp in linux) or would (tap) support multiqueue. In such kind of tap backend, each file descriptor of a tap is a qeueu and ioctls were prodived to attach an exist tap file descriptor to the tun/tap device. So the patch let qemu to

Does anyone out there have any thoughts on the type of load common DTrace scripts would cause on a system if run 24x7? I know "common DTrace scripts" and their underlining probe calls a vague statement. So for the lack of a common and establish set of scripts in the OS, I''ll use the most popular right for my question...the DTraceToolkit from Brendan Gregg. Which by the

I am [trying to] perform a test prior to moving my data to solaris and zfs. Things are going very poorly. Please suggest what I might do to understand what is going on, report a meaningful bug report, fix it, whatever! Both to learn what the compression could be, and to induce a heavy load to expose issues, I am running with compress=gzip-9. I have two machines, both identical 800MHz P3 with

I was wondering if there is a way to monitor and gather metrics for Samba. We would love a solution that would be able to plot the number of connected users, file usage, samba server load, etc. Does anyone have any of these tools or any suggestions? Something similar to smbstatus but with more information and the ability to output (for graphing and logging). -marc

Hello List Folks. I?m trying to do manova using a function which assembles the response (LHS) and factors (RHS) from different sources. When I do so, the model routines complain that I'm passing a list for the RHS when I don't think I am. Here's a toy example: r <- matrix(rnorm(30), ncol = 3) # toy data td <- list(d = rnorm(10), f1 = sample(c("A",

I''m trying to look at a page, and get all the urls for the links as absolute urls. I searched briefly, and couldn''t find any answers for the ruby version. Is this kind of operation supported? or do I have to do it by hand. #what I tried, this doesn''t work :( !!! uris = [] page.links.each {|x| y.push(x.uri()) } # or page.links.each {|x| y.push(x.href) } Thanks!

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm currently positively having winbind authentication against a DC and pam also works with it. I'm also using PAM authentication in PHP with the help of the pam_auth module which provides one function in PHP, pam_auth($user, $pass) which returns true/false. I would like to get more information and do more tests with the authenticated

Hi friends - I'm plotting a ratio of bicarbonates i ggplot2 and ylab(expression(paste(frac("additive BIC","true BIC")))) worked OK - but now I have been asked to put the chemistry instead - so I wrote ?ylab(expression(paste(frac("additive",HCO[3]^"-","true",HCO[3]^"-")))) - and frac saw that as additive = numerator and HCO3- =
