Hi, Does anybody know how virt-manager is getting the CPU usage of the guests? I need to know how to get the CPU usage of the guests and this is the only way I can think of. In other words, how does virt-manager produce the graph of the CPU usage of EACH guest in KVM? I don't actually need the graph, I just need to get the percentage(%) since I'm trying to create a Java program to get

Hi,        Is it possible to get the CPU usage of a guest through a virsh command? I have tried almost all the commands (vcpuinfo, cpu-stats, etc.) that gets the details of a guest cpu, but it only returns the cpu time. Is there any command that returns the cpu usage (just like the graph that virt-manager displays) of a guest? Or do I have to create a program using libvirt API? Thanks in

Hi r users, I have two data sets (X1, X2). For example, time1<-c( 0, 8, 15, 22, 43, 64, 85, 106, 127, 148, 169, 190 ,211 ) outpue1<-c(171 ,164 ,150 ,141 ,109 , 73 , 47 ,26 ,15 ,12 ,6 ,2 ,1 ) X1<-cbind(time1,outpue1) time2<-c( 0 ,8 ,15 , 22 ,43 , 64 ,85 ,106 ,148) output2<-c( 5 ,5 ,4 ,5 ,5 ,4 ,1 ,2 , 1 ) X2<-cbind(time2,output2) I want to

Hi, I would like to merge two data frames. It is just that I want the merging to be done with some kind of a fuzzy criterion. Let me explain. My first data frame looks like this : ID1 time1 dt 1 2008-01-02 13:11 10 2 2008-01-02 14:20 20 3

Hello all, I've 2 strings that representing the start and end values of a date and time. For example, time1 <- c("21/04/2005","23/05/2005","11/04/2005") time2 <- c("15/07/2009", "03/06/2008", "15/10/2005") as.difftime(time1,time2) Time differences in secs [1] NA NA NA attr(,"tzone") [1] "" How can i

To Whomever is Interested, I have spent several days searching the web, help files, the R wiki and the archives of this mailing list for a solution to this problem, but nonetheless I apologize in advance if I have missed something obvious. The problem is this; I have a 5-column data frame with about 4.2 million rows, and want to create a new (and hopefully much smaller) data frame that

Hello, Below is the code for a basic bar graph. I was seeking advice regarding the following: (a) For each time period there are values from 16 people. How I can change the colour value so that each person has a different colour, which recurs across each of the three graphs/tie epriods? (b) I have seen much more sophisticated examples using lattice (e.g each person has a separate

Hi all I am running a 2-way repeated measure anova with 1 between-subjects factor (Group=treatment, control), and 1 within-subject factor (Time of measurement: time1, time2). I extract the results of the anova with: summary(aov(effect ~ Group*Time + Error=Subj/Time, data=mydata)) Now, this must be clearly a dumb question, but how can I quickly extract in R all the post-hoc t-tests for the

Further pursuing my curiosity to measure the efficiency of R/C++ interface, I conducted a simple matrix-vector multiplication test using .C and .Call functions in R. In each case, I measured the execution time in R, as well as inside the C++ function. Subtracting the two, I came up with a measure of overhead associated with each call. I assume that this overhead would be non-existent of the entire

Dear All, what determines if a difference between POSIXct objects gets expressed in days or seconds? In the following example, it's sometimes seconds, sometimes days. as.POSIXct('2009-09-01') - as.POSIXct(NA) Time difference of NA secs c(as.POSIXct('2009-09-01'), as.POSIXct(NA)) - c(as.POSIXct('2009-09-01'), as.POSIXct('2009-08-31')) Time differences in

Dear list-members I am new to R and a statistics beginner. I really like the ease with which I can extract and manipulate data in R, and would like to use it primarily. I've been learning by checking analyses that have already been run in SAS. In an experiment with Y being a response variable, and group a 2-level between-subject factor, and time a 5-level within-subject factor. 2

Hi! I'm comparing the cpu usage of a VM from virDomainGetInfo and the usages returned per-vcpu from virDomainGetVcpus and the totals do not match up. I expect that the cpu usages reported per-vcpu, when summed, should equal the total cpu usage of the domain, but there is quite a large gap between them. Is there something I'm missing? See this example code using the python

I'm trying to fit a Cox proportional hazards model to some hospital admission data. About 25% of the patients have had at least one admission, and of these, 40% have had two admissions within the 12 month period of the study. Each patients has had one of 4 treatments, and one of the treatment groups has had no admissions for the period. I used:

Greetings sir,                   I am currently taking up Computer Science in my school. I just want to ask how do you get the CPU usage and Memory usage of the VMs (I'm referring sir to the graphs that the Virtual Machine Manager is displaying)? I need to get the numbers (the numbers are enough, I don't need the graph) of these informations because I will be needing it for my

Greetings everyone,        I just want to ask if it is possible to get the CPU usage of the VMs in KVM through libvirt? I mean, how does the virt-manager produce the graph it displays? Is there a way get this graph? But instead of the graph itself, I just need to get it in percentage(%) form. I'd like to know how. Thank you and your help will be greatly appreciated. regards, Marco

I'm having a problemin understanding the Libvirt Java API. Here is my sourcein reading some of the classes: http://libvirt.org/sources/java/javadoc/ I have no idea where to start in order for me to get the CPU usage. Can anybody help? Or at least give me some points on where to start in order for me to get the CPU usage of a VM in KVM? Any suggestions will really help. Thanks regards,

Hi all libvirt-users, Is there a counterpart on Java of the function virDomainGetCPUStats that is based on C API? Because I am trying to create a program based on java to get the CPU usage of a Guest/Domain/VM in KVM using the Libvirt Java API. Honestly, I am having a hard time in starting my program. I have no idea where to start. I mean, what functions do I need to get the CPU usage of
