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

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?

Dear list, as my Xen3 server is finaly becomming ready for production I was wondering if anyone has written a xen usage monitoring/logging tool? Something like xm top, but with continuose logging to a (rr)database. Or a munin plugin? I can''t remember seeing anything simmilar on the list. BTW: where does xm top get the NETTX(k) and NETRX(k) from? For a munin plugin I''d

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.

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

Cycling around many CPUs in XenMon''s curses mode can get cumbersome. This trivial patch adds bindings to move to the previous CPU. The next/previous binding seems more natural to me than the earlier cycle binding, but we can keep them all for now. # HG changeset patch # Node ID 146b5c76086c07fad61bea7ccf60f2f4fd66abbd # Parent 7dd31dbf16e75f0f70e0f9c44b2bb2b5fc6eecf1 Add next/previous

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, I am using Xenmon to measure performance of Credit and SEDF schedulers. But as you know, the metrics displayed by xenmon keep refreshing on the screen. When I tried redirecting the xenmon output, I am seeing the attached file. Is there any better way to record results which I can use to draw graphs? Please guide.. Thank you Warm Regards Ananth

Package: xen-utils-3.0.3-1 Version: 3.0.3-0-3 Severity: grave Tags: security Justification: user security hole Xen versions 3.x, and 3.1 contain a tool for processing Xen trace buffer information. This tool uses the static file /tmp/xenq-shm insecurely allowing a local user to truncate any local file when xenbaked or xenmon.py are invoked by root. Sample session: # setup. skx

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

This is getting pretty convoluted. The current behavior is consistent with the description at the top of the help page -- it does not promise to stop evaluation once the first non-TRUE is found. That seems OK to me -- if you want sequencing you can use stopifnot(A) stopifnot(B) or stopifnot(A && B) I could see an argument for a change that in the multiple argumetn case reports _all_

In "Understanding the Linux Kernel" 3rd edition, section 4.7 "Softirqs and Tasklets" it states: "Activation and execution [of defferable functions] are bound together: a deferrable function that has been activated by a given CPU must be executed on the same CPU. There is no self-evident reason suggesting that this rule is beneficial for system performance. Binding the
