I recently did a backport of a couple of networking bug fixes from s10x_u4_b6 to s10x_u3_b10. I patched just /platform/i86pc/kernel/unix and /platform/i86pc/kernel/amd64/unix in my existing u3 OS image and I''m seeing this dtrace problem when running any dtrace script: NODE hcb101 ~ $ ./tcpstat.sh dtrace: failed to compile script /dev/fd/10: "/usr/lib/dtrace/procfs.d", line 316: translator member pr_clname definition uses incompatible types: "char [8]" = "priv_set_t [4]" I can comment out the offending line in procfs.d: pr_clname = `sclass[T->t_cid].cl_...

...e NAS-Filer, with different workload coming from the recording/editing-PC's. I'll do repeated single as well as multiple parallel recording/editing sessions of about 10 min, and I want to measure at intervals of max. 5 seconds (as time series), using the sysstat (vmstat, iostat, mpstat) and tcpstat and netacct tools. My questions are now: - are these the correct tools for giving me the right values, which I could further consolidate and analyze in some tablesheet (I cannot buy commercial ones, and I think SNMP/MRTG is not the right tool in this case)? - what will the bottlenecks probably be...

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
