Message-ID: <46B1A6D0.8080504@crpa.it> Date: Thu, 02 Aug 2007 11:41:36 +0200 From: Cristian Veronesi <c.veronesi@crpa.it> Subject: [suse-sles-e] systemtap, anyone?
Has anyone tried to use systemtap on SUSE SLES10? I was able to run a
simple "hello world" script but I always get errors when trying to
access kernel functions. For example, this script:
<<<
global reads
probe begin {
printf("probe beginning\n")
}
probe syscall.read {
reads [execname()] <<< count
}
probe end {
foreach (prog_name in reads) {
printf("Name: %s, # Reads: %d, Total Bytes: %d, Avg: %d\n",
prog_name, @count(reads[prog_name]),
@sum(reads[prog_name]), @avg(reads[prog_name]))
}
}
>>>
Gives the following error:
semantic error: libdwfl failure (dwfl_linux_kernel_report_offline): No
such file or directory while resolving probe point
kernel.function("sys_read")
semantic error: no match for probe point while resolving probe point
syscall.read
Pass 2: analysis failed. Try again with more '-v' (verbose) options.
Am I missing some package? Arun Singh in the suse-oracle mailing list
suggested me to install kernel-default-debuginfo package, but I'm not
able to find it in the yast repository.
Thank you. Kind regards,
