QUESTION
I am building a project inside the docker container without any resource limitation on creating the container. when I am monitoring it, I see the different results for CPU usage.
from ctop
From the Grafana (Full Node Exporter Chart)
I do not understand why the results are different, specially with ctop command.
but my main question is, does Docker really use all CPUs? this machine has 16 vCPU and 16GB RAM
ANSWER
Answered 2021-Aug-20 at 09:27It's not exactly clear in the node exporter what instance or container you are monitoring, though it seems like the node exporter it showing the total machine CPU usage in 0-100 format and ctop shows in 100% per vCPU format. Also try using docker stats, that should show all running containers resource usage, from cpu to network and disk usage, when using it each vCPU would as 100% so your total will be 1600% for 16 vCPU.
Regarding the cAdvisor output it doesn't show the same time range as the grafana node exporter so it would be hard to make a hard conclusion but it seems like similarly to ctop and docker stats it shows on a per core basis but instead of percentage it shows in 'cores' unit of measurement
QUESTION
I've tried to solve the system of equations of neutronic kinetic with two feedbacks (the fuel temperature feedback and the coolant temperature feedback) using RADAU method in python.
...ANSWER
Answered 2020-Jun-11 at 10:44It is not explicitly said in the documentation, but Radau is just the stepper class for the method, the return of a successful call to this constructor is a stepper object. To get a result similar to odeint use the general interface method
QUESTION
I have a deployment in k8s environment and ran ctop command to see memory and cpu utilization.
NAME CID CPU MEM NET RX/TX IO R/W PIDS
◉ k8s_POD_pod1-… c029e2492e7b 0% 1M / 23.54G 0B / 0B 0B / 0B 1
◉ k8s_pod1_… 411fc43165fe 6% 23M / 23.54G 0B / 0B 0B / 0B 115
why there are k8s_POD_* and k8s_*, two containers for single entity?
ANSWER
Answered 2020-May-11 at 11:51I guess your pod contains a single container, that is why you are asking this question (which is indeed a good question!).
So, one of these containers is the one you actually deployed, but the second one is a Kubernetes infrastructure container, known as a pause container.
This pause container is the container that holds all the containers of a pod
together. All containers of a pod share the same network and other
Linux namespaces. The pause container is an infrastructure container whose sole
purpose is to hold all these namespaces. All other user-defined containers of the pod then use the namespaces of the pod infrastructure container.

QUESTION
I want to publish the C# project,Visual Studio 2019 ,WPF.
First, application publish; Second, install the application; Third, a window pops up after the application installation is complete, showing an error: "An error occurred while loading the configuration file"
I want to put the configuration file in the publish application.
[Code in Visual Studio 2019 WPF][2]
(MainWindow.cs)
private void MainWindow_OnContentRendered(object sender, EventArgs e) { // loading the configuration file try { Config = RimageConfig.LoadFromFile("config.json"); } catch { ShowError**("An error occurred while loading the configuration file", Close);** return; }
(config.json) { "Rk": 0.3167,// "Rb": -1.6349, "Rg": 8.6982, "Rt": 200, //"CLeft": 655, //655 "CLeft": 520, //655 "CTop": 120, "CWidth": 2350, "CHeight": 2300, "Pa": 100, "Pb": 30, //"Pa": 255, //"Pb": 0, }
...ANSWER
Answered 2020-Feb-06 at 09:08A configuration file should probably not be statically defined at compile-time, otherwise it defeats its purpose of being editable later without rebuild.
Your application should survive start-up without a valid configuration file, because this file will be edited by end-users and thus contain errors.
If you only need a static configuration file, you could change your configuration file "Build Action" to "Embedded Resource" and load it using Assembly.GetExecutingAssembly().GetManifestResourceStream() method. That would mean they would no longer be editable after build though.
You can also have your code create the configuration file on start-up if it doesn't exist and have it filled with default values (for example, by using default values loaded from an embedded configuration file).

Vulnerabilities
No vulnerabilities reported
Install ctop
You can use ctop like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
