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...

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 # Pa...

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 Shin''ya _______________________________________________...

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, 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 dom...

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.....

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.

...ance of Credit scheduler with SEDF scheduler. Also, is it possible to get the sequence in which the VMs are scheduled? Please provide your suggestions and guidelines as to how I can go about running different I/O intensive applications as well as computation intensive applications on them, and use xenmon to evaluate their performance.

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? T...

...ersion: 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.

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

...Hypervisor I installed a Xen (3.3.0) on an Ubuntu 8.04 to test some things and get more familiar with Xen regarding accounting. I have two questions: 1. CPU monitoring +++++++++++++++++ I have discovered something strange regarding CPU usage monitoring. I found a CPU monitoring tool called "xenmon.py". I have to explain my problem with the help of a screenshot. On top left side on "screenshot.png" you can see that Dom0 is pinned to CPU 0 and my two VMs are pinned to CPU 1. (Both VMs use also Ubuntu 8.04). Also you can see that vm2 and vm3 have each a cap of 40%. On the lef...

...is based on the specification of the trace buffer control function trace.c/tb_control(). The function checks the trace buffer is initialized or not in line 183. If not, this routine stops working. Of course, this problem is also solved by using tbctl [0|1]. But this problem is already solved by xenmon.py without using tbctl command. This code is just moved from tools/xenmon/xenbaked.c(get_tbuf and misc settings) I hope these two tools (xenmon.py and xentrace) share the functions.

...was .069%, and was gotten by timing a simple cpu-intensive task running with trace buffers compiled in and again with trace buffers not compiled in. It''s important for us to have the trace buffer functionality totally enabled by default, so we can depend on its availability for running XenMon without requiring recompiling and rebooting.
