Re: Versions

Hi Michael: Thanks for making the SCTP probes! The 1.6.3 bit probably comes from the version of the API that D exposes, as seen here: https://github.com/freebsd/freebsd/blob/master/cddl/contrib/opensolaris/lib/libdtrace/common/dt_open.c#L137. Adding new things should probably be done in the

Re: Include header files in dtrace scripts

Hi Farhan: You should call DTrace with -C, which is the C preprocessor: --- #!/usr/sbin/dtrace -Cs #include #include #include #include --- — Domagoj > On 5 Aug 2018, at 06:43, Farhan Khan wrote: > > Hi all, > > I am trying to run dtrace on some net80211

Re: Filter out dtrace(1) probes

Hi Farhan: I'm not sure what the question is, but by what I understood it sounds like a predicate with probefunc should do? i.e.: prov:mod:func:name /probefunc != "something_i_dont_care_about"/ { something_here } — Domagoj > On 17 Aug 2018, at 00:49, Farhan Khan wrote: > > Hi all, > >

Structured/machine-readable output for DTrace

Hi: I've implemented machine-readable output in the form of JSON, XML and HTML into libdtrace, and by extension dtrace(1) using libxo. The goal is not to replace linking to libdtrace in any way when one wishes to build a custom application around it, but rather to supplement it (as it would

Query about work with/on DTrace

Hi: I'm in the process of writing an article for the FreeBSD Journal regarding DTrace and was hoping to get some submissions of what people are working on in what would be called the "exciting new work" part of the article. If you'd like to share your work with a quick summary and link to
