Dear all: In dtrace.c, function dtrace_probe_create(), there''re a piece of code: id = (dtrace_id_t)(uintptr_t)vmem_alloc(dtrace_arena, 1, VM_BESTFIT | VM_SLEEP); id is uint32_t, and I think id is used as an index to array dtrace_probes[] but why not just use id = cur_value + 1, cur_value is a global variable to record the lastest id? Is this a trick? for what? Thanks :)

Hi. I would like to print out a field of a vnode, but the argument to the function is of type vnode_t **. If I set "this->vpp" to arg2 in an entry function to zfs_lookup(), I''d like to retrieve the value of one of the fields of *(this->vpp) in the return function. Something like the below (but the syntax below is not right): printf("zfs_lookup:

Hi, >From what I have read, the create-vnic feature in dladm is only available within the context of crossbow...? Specifically, what I am wondering is whether it is at all possible to successfully install crossbow on top of Sun''s "Standard/sunsolve supported" Solaris 10/08 rather than OpenSolaris, per. Se.... Is this at all feasible? Many thanks in advance.. Best

(Bcc''ed to networking discuss). Hi All, Have enclosed man page draft for dlstat(1M) herewith. This is part of the effort to gain better visibility into network traffic in light of crossbow features like virtual NICs, interrupt vs. polling modes etc. This in turn would greatly assist network performance analysis. It is also aimed at segregating link/flow configuration from

I''ve implemented code to send out bogus gratuitous ARP packet from vna in order to fix CR 6701114.

But, the

Dear All, recently our customer met some udp checksum error in v40z, we have done below testing: Sending: v40z, solaris 10 update 2 with 125121-03 patch receiving: v40z with solaris 10 update 2 and a PC-server with windows 2 receiving host connect in the same network switch. in sending v40z, we set ip:dohwcksum=0 in /etc/system. The sending peer send out packets at about 40M/s, the windows

Hi All, Is there a simple way to list all currently open file descriptors ? TIA.. Regards, Venkat -- This message posted from opensolaris.org

Dear Experts, Is there a foolproof way of getting hostid on solaris 10 sparc? I am asking this because i have seen Dtrace scripts which allow to change hostid. I want this because i want to tie down my application to specific host and do not want my client to re-use it on other machine just by changing hostid. Thanks, -- This message posted from opensolaris.org

Is there any way to get printf type functionality inside the kernel from dtrace probes. Basically I want to dump progress through flow in my device driver. Something like: DTRACE_PRINTF("Inside chip reset, mailboxes %x %x %x %x %x %x %x %x", mb1, mb2, .....); ... ... DTRACE_PRINTF("reset failed: reason %s", failure_reasons[err]); I may have several such probes and they may

Howdy, We are running zones on a number of Solaris 10 update 3 hosts, and we are bumping into an issue where the kernel doesn''t clean up connections after an application exits. When this issue occurs, the netstat utility doesn''t show anything listening on the port the application uses (8080 in the example below), but connections are still listed in the ESTABLISHED state: $

Hi, I am new to DTrace. Want to capture (for specific port #s) the loopback interface (lo0) tcp message flow with the complete message body. Is this possible with DTrace? Are any examples available?

Folks, I just posted an updated Crossbow virtualization architecture document. The new revision is available at: http://opensolaris.org/os/project/crossbow/Docs/crossbow-virt.pdf The main changes are the addition of support for multiple MAC addresses per client, and an explicit separation between consolidation private and project private MAC API entry points. See in particular the

The following is mainly a capture of parts of multiple off-line discussions within members of the Crossbow team (Gopi, Thiru, Roamer, May-Lin, Thirumailai, Nitin, KB, ...), I thought I''d open it up to other participants. Crossbow''s core scheduling involves switching a NIC (or individual Rx rings on the NIC) to polling mode. The receive interrupt will become not only rarer,

Hi, we are developing and operating an very critical application in the financial sector. Now our customer wants us to report performance data (roundtrip times of the messages routed). My idea is using dtrace to measure the times with the pid provider catching the timestamps on entry of the in and out functions of the processes. Now my questions ;-): 1) Is this an appropriate method to monitor
