Subject: RE: Anyone tried SystemTap with the latest RHEL5 Beta refresh
Date: Fri, 27 Oct 2006 21:05:00 -0000 [thread overview]
Message-ID: <9AE298E00BCF7B469C04BE82FCE78B8701CB7F36@scsmsx414.amr.corp.intel.com> (raw)
Can you check your tapset/ioblock.stp to see if you have this probe
ioblock.request() ?
If you don't, and you have ioblock.submit() instead, it means you have
an earlier version of tapset. In that case, you can try this modified
script.
#! stap
probe begin {
printf("DEVNAME\tSECTOR\tRW\n")
}
probe ioblock.submit {
printf("%s\t%d\t%d\n", devname, sector, rw)
}
probe ioblock.end {
printf("%s\t%d\t%d\n", devname, sector, rw)
}
