similar to: [PATCH 0/2][Resend] Display VBD information by xentop. ver.2

This patch series provides the function to display VBD information through xentop. VBD information will be possible to get through sysfs which is locale in /sys/devices/xen-backed/vbd-x-xxxx, by previous patch. In this patch series, libxenstat collects these information and xentop display tem. The change from ver.1 is only libxenstat in order to handle sysfs information. I appreciate any

Hi. These patches add the output function for blktap statistics into xentop. Currently, xentop outputs only blkback statistics, and not blktap statistics. By these patches, xentop is made cover both blkback and blktap. In xen, back-end driver has two types; blkback and blktap. Blkback driver is old back-end driver. Blktap driver is new back-end driver and is recommended currently. Usage of both

This patch make xentop output statistics about both blkback and blktap. And, xentop also display back-end driver type in detail view mode. # HG changeset patch # User s-uchida@ap.jp.nec.com # Date 1180665749 -32400 # Node ID 1b36d6f6c7a98728382de93ee23c8c97b0b95dbd # Parent 1768a89bb87824249827d935d7803d8193bdeb05 XENTOP: Displaying blktap information.

This series of patches provides the function to get counts of I/O requests. This function is useful for managing I/O resources to support workload management. It is important to manage resources such as cpu time, physical pages and disk I/O bandwidth for workload management. In Xen, now, cpu and memory resources can be managed, but I/O resource can not be managed. I think that it is necessary to

This patch provides a I/O request management framework. This framework can control virtual block device threads at 7 places : * deciding that virtual block devices(threads) is ether going or waiting, * before allocating pending_request variables, * after allocated pending_request variables, * after allocated no pending_request variables (Namely, out of request), * after freed

Hello, I noticed that the CPU% reported by xentop appears to be too high. With dom0 idle xentop is reporting between 14-17% CPU utilization while at the same time top in dom0 is reporting 1-4% CPU utilization. I see that the TODO for xentop includes a task to make CPU% more accurate but looking at the code for xentop and libxenstat I''m not sure how to go about this. Assuming the CPU

Hi all, Now I use xentop to get disk statistical information. NAME STATE CPU(sec) CPU(%) MEM(k) MEM(%) MAXMEM(k) MAXMEM(%) VCPUS NETS NETTX(k) NETRX(k) VBDS VBD_OO VBD_RD VBD_WR VBD_RSECT VBD_WSECT SSID Domain-0 -----r 96233 0.7 3902464 23.3 no limit n/a 12 0 0 0 0 0 0 0 0 0 0 slave3

On my system, I''m getting SIGSEGVs in xentop because xenstat_node_domain() is returning NULL. Skip the loop if it does rather than crashing.

Hello to all, Does anyone know if there is an iteration option planned for xentop (similar to top) to make it easier for simple shell scripts to scrape the output? I don''t see one in tools/xenstat/xentop/xentop.c , but I''ve been meaning to play with stuff in libxenstat anyway. If its going to be added soon I''ll tinker much later than sooner. TIA :) Best, -Tim

Hi Is there a place where I can get explaination for VBD and N/W related stats produced by xentop ? Or if some one knows.. can they please reply to this email. Thanks in advance. -nb _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Good suggestions - you are right that we only have issues when a VM is in transition so simply removing it from the returned list should be fine. Turns out that this also means the collectors don''t need to return special codes either - they are back to either working (and potentially pruning a domain from the list) or failing completely. Patch attached (boy, this is taking waaay more

All, I have a domU running Ubuntu 12.04.1 LTS 64bit using PVonHVM which is working well but I noticed a quirk and just wanted to check it wasn''t just my misunderstanding. On my dom0 (Arch Linux, 64bit, AMD Phenom 2 X4 965 CPU, Xen 4.2.0 from my own PKGBUILD) I run "xl top" and xentop loads and shows all the currently running domains; only none of the domains have anything

Hello All, As I''m going to write some kind of a monitoring sensor, which will use the same information "xentop" currently provides, I would like to know if libxenstat can be considered as stable? Will libxenstat be supported in future versions of Xen? Or is it rather advisable to get this information from the Xen Management API, which maybe provide the same data? The sensor

Package: libxen-dev Version: 4.1.4-3+deb7u1 Severity: wishlist Dear Maintainer, I want to make some fine monitoring of my xen machines and the xentop utility does not exactly fits my needs I saw in the sources that it uses some kind of library named libxenstat wich seems very acurate. This library is already built to make the xentop utility but the debian package does not makes it available as
