Satistics counters is useful for debugging and performance optimization, so this patch lets virtio_net driver collect following and export them to userspace through "ethtool -S": - number of packets sent/received - number of bytes sent/received - number of callbacks for tx/rx - number of kick for tx/rx - number of bytes/packets queued for tx As virtnet_stats were per-cpu, so both

This patch adds simple python to display vhost satistics of vhost, the codes were based on kvm_stat script from qemu. As work function has been recored, filters could be used to distinguish which kinds of work are being executed or queued: vhost statistics vhost_virtio_update_used_idx 1215215 0 vhost_virtio_get_vq_desc 1215215 0

To help in vhost analyzing, the following series adding basic tracepoints to vhost. Operations of both virtqueues and vhost works were traced in current implementation, net code were untouched. A top-like satistics displaying script were introduced to help the troubleshooting. TODO: - net specific tracepoints? --- Jason Wang (2): vhost: basic tracepoints tools: virtio: add a

Hi all I am looking for an add-in. I am currently working on something and I use daily data of closing stock prices. As not all companies are traded daily (e.g. on monday, then on thursday etc) at the stock exchange, there is satistically a problem. There are some papers which explain the approach to handle infrequent trading of a stock or non synchronous data and beta estimation (Dimson, 1979; Scholes & Williams, 1977). I looked for add-ins which do address this topic, but i couldn't find any. I have to calculated daily...

Recent debugging on vhost net zerocopy shows the need of tracepoints. So to help in vhost{net} debugging and performance analyzing, the following series adding basic tracepoints to vhost. Operations of both vhost and vhost_net were traced in current implementation. A top-like satistics displaying script were introduced to help the troubleshooting: vhost statistics vhost_virtio_update_used_idx

Currently, we store the statistics in the independent fields of virtnet_stats, this is not scalable when we want to add more counters. As suggested by Michael, this patch convert it to an array and use the enum as the index to access them.

Hi, You didn't specify the satistical model you are intereted in, I will suppose it is something like: #Organims ~ Landscape + Soil + Depth + Species I suppose you have a table of with something like... Spec Lands Soil Depth #Organisms A 1 1 1 10 A 1 2 1 2 B 1 1 1 0 B 2 2 2 2 ... etc, Normally, the count of organisms in soil sample...

Hi, there, I'd like to get a statistics to reflect the correlation of two time serials observations. for example, one time serials over time 1 to 20, and another one from same time points from 1 to 20. I need one scalar satistics as a correlation of these two observations. Thank you and have a good weekend! Jieping Zhao PhD student in Bioinformatics, NCSU Lab homepage:

Hi all: This series is an update version of multiqueue virtio-net driver based on Krishna Kumar's work to let virtio-net use multiple rx/tx queues to do the packets reception and transmission. Please review and comments. Changes from v5: - Align the implementation with the RFC spec update v4 - Switch the mode between single mode and multiqueue mode without reset - Remove the 256 limitation
