Hi, I read about RPC interface for xenmon in this presentation: www.xensource.com/files/xs0106_xenmon_brief.pdf Has such interface been implemented yet by anyone?

Hi, This patch removes the magic number "31" for readability. The number "31" means the idle domain ID. In detail: - display the idle domain ID with "Idle" instead of "31" - write to the file "log-idle.log" instead of "log-dom31.log".

Hi, This patch adds the argument check of "--ms_per_sample=" option. For "--ms_per_sample=", a negative value should be invalid. e.g. % xenmon.py -n --ms_per_sample=-1 usage: xenmon.py [options] xenmon.py: error: option --ms_per_sample: invalid negative value: ''-1'' Signed-off-by: KUWAMURA Shin''ya <kuwa@jp.fujitsu.com> -- KUWAMURA

Hi, Can someone clarify for me the numbers that show up in Xenmon? Specifically, I''m curious about the "domain31" entry which always shows up. It looks like this represents the free resources. Also, does anyone know what would happen if more than 30 domain0''s were started (or more likely, I did enough migrations to raise the next domain ID to above 30)? Thanks for

Package: xen-utils-3.0.3-1 Version: 3.0.3-0-2 For some reason, xenmon.py is not in the search path - maybe an issue of the wrapper used by the xen Debian packages seems to be only a link to the wrapper is missing the program exists in the package xen-utils-3.0.3-0-2 and the follwoing make it work: ln -s ../lib/xen-common/bin/xen-utils-wrapper /usr/sbin/xenmon.py ln -s

Once Xen calculates nr_nodes properly, all nr_cpu calculations based on nr_nodes * sockets_per_node * cores_per_socket * threads_per_core are broken. The easy fix is to replace those calculations with a new field, nr_cpus in physinfo which is calculated by num_online_cpus(). This patch does so and attempts to change all users over to nr_cpus field in physinfo. This patch touches

Last month Mark Williamson sent out a patch to unconditionally enable the trace buffer. I''d like to suggest that his patch be accepted and merged. I have performed some simple benchmarks to quantify the overhead associated with the trace buffer and calls, and found a negligable performance loss due to them. The actual number was .069%, and was gotten by timing a simple cpu-intensive

Hi, I have installed Xen 3.3.1 with Ubuntu 8.04 as dom0 and fedora9 (from jailtime.org) as Dom1. I have more instances of the same fedora9 with separate config files running as other guest domains. But these guest domains dont have any program / application running. So, xm list shows that they are in blocked state as no activity is happening. I wrote a shell script that counts upto large numbers

Hi list, I''m working on monitoring CPUs usage per domU, I/O.... using xenmon parsing its output and finally polling the results with cacti. Any advices? If all works OK I will post my work to the list.

In XenMon''s file appending mode, a lot of times I''ll get a strange first data point, e.g., the cpu% for dom0 will be 99.9 but the rest of the readings will be 19-21 which are sane for the run. I''ve been throwing the data point out, but was curious about it. Is it unavoidable? Thanks, Tim _______________________________________________ Xen-devel mailing list

Testing on an 8-node 128-way NUMA machine has exposed a problem with Xen''s nr_cpus calculation. In this case, since Xen cuts off recognized CPUs at 32, the machine appears to have 16 CPUs on the first and second nodes and none on the remaining nodes. Given this asymmetry, the calculation of sockets_per_node (which is later used to calculate nr_cpus) is incorrect:

Good day. I found that XCP ignores VCPU-params (weight and cap) after VM live migration, as well, as those parameters ignored if changed on running VM. May I as someone with xcp cloud nearly check this bug? Thank you. -- wBR,George. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

This patch modifies the physinfo hcall to export NUMA CPU and Memory topology information. The new physinfo hcall is integrated into libxc and xend (xm info specifically). Included in this patch is a minor tweak to xm-test''s xm info testcase. The new fields in xm info are: nr_nodes : 4 mem_chunks : node0:0x0000000000000000-0x0000000190000000

Aiming at a release some time in August, I''d like to cut RC1-s by Thursday next week (as I''ll be on a two week vacation starting Friday). Please indicate any bug fixes that so far may have been missed in the backports already done. A few fixes are currently stuck in master''s staging branch (or pending to make it there) - these don''t need to be named explicitly,

Added two new sets of compile flags, and pass them to the check scripts, so libraries and includes are searched there also. Resend this patches because they suffered some modifications and where scattered along the mailing list. Please review, thanks Roger. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi, Can someone please tell me if there is a multiprocessor version of xentop available or in the making ? I notice that the current xentop does not give any information per physical cpu on a multiprocessor machine.

Hello, this patch introduces HVM tracing: one tracing class for both, SVM and VMX. It adds several new trace events. So we can differentiate between them in the xentrace formats file and format each event''s data items appropriately. With this patch the xentrace_format output is much more informative. The previous simple tracing in SVM and VMX is completely replaced. Unfortunately I

Attached is the second release of XenMon, which is a unique performance monitoring tool for Xen. Instead of using hypervisor calls to get domain information, we use the xentrace facility to provide fine-grained monitoring of various metrics (see README below). We have written up a small case study that demonstrates the usefulness of the tool and the metrics that it reports. This will be
