Hello all, i''m trying to run the tool tcptop from the dtracetoolkit but it fails. I got the following error: tcptop -C 30 dtrace: failed to compile script /dev/fd/11: "usr/include/sys/kstat.h", line 439: invalid type combination I let it run on different machines on a Ultra 45 and a E20K both with Solaris 10 same result. any ide...

I see Intel has released a new tool. Oh, it requires some patches to the kernel to record latency times. Good thing people don''t mind patching their kernels, eh? So who can write the equivalent latencytop.d the fastest? ;-) http://www.latencytop.org/ -- cburgess at qnx.com

I try to run tcptop in solaris 10 x86 with patch level 125101-04 and I get the following error /usr/include/sys/zone.h line 16: can''t find include file sys/tsol/label.h error. Is there a work around for this problem? -- This message posted from opensolaris.org

...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 Net directory don''t work. For those of you internal to Sun, tcptop is temporarily here: /net/liondra.sfbay/export/share1/DTraceToolkit-0.92/Net These scripts work great on an s10 RR box. But, unfortunately on an snv_31 box, the SS_TCP_FAST_ACCEPT variable isn&...

Is there any work on keeping DTraceTools up to date with the latest snv builds. These scripts are pretty useful and help get a novice dtrace user like me doing useful work quickly. Specifically the tcp stack tools like tcptop and tcpsnoop don''t work with later OpenSolaris builds. Thanks, Gary -- This message posted from opensolaris.org

...software-bridge( using iperf3 bandwidth/latency on the host and guest was almost the same) and disk write(using qemu-img convert src dest file both on the host and guestvm was comprable) being the issue. Next I profiled both sshd and qemu-img during the conversion phase using bpftools (profile and tcptop) and this is what i see. Time (min) File Size (KB) sshd RX (KB) tcptop qemu-img RX (KB) tcptop profile (flamegraph) 0 - 5 5478400 5612971 5601536 qemu-img-0-5.svg 5 - 10 8365440 (+2887040) 5669043 5656517 qemu-img-5-10.svg 10 - 15 8423296 (+57856) 5722376 5708926 qemu-img-1...

thanks Richard, The experiment was indeed done with nested VM enabled. I am not sure about the internals, but i thought once overlay is setup the 2 main processes are sshd and qemu-img convert (reading data from sshd and doing the conversion) I don't see any of the qemu process running. Initial overlay setup was pretty quick and rest of the time was spent in qemu-img convert operation Suresh

hi, i want to find out the total number of incoming connections for a machine at any time using dtrace.anyone please suggest me the solution. This message posted from opensolaris.org

Hi list. I have rebuilt tcptrack now. You can get it from here: http://www.karsites.net/centos/downloads/5.5/tcptrack-1.3.0-1.el5.i386.rpm It's not signed, so to install it with yum as root user, do: # yum localinstall --nogpgcheck tcptrack-1.3.0-1.el5.i386.rpm in the directory you d/l it to.
