Here's an overview of some of the best free and open source database software tools for Macs. InnerSoft STATS by InnerSoft is a.$ docker run -it -rm -privileged -pid =host justincormack/nsenter17 of the Best Database Tools for Macs. EViews by Quantitative Micro Software, also known as Econometric Views, is a statistical tool. The latter two components are optional and can be ommitted when choosing 'custom install', they are only needed. Contains R 4.1.1 framework, R.app GUI 1.77 in 64-bit for Intel Macs, Tcl/Tk 8.6.6 X11 libraries and Texinfo 6.7. R 4.1.1 binary for macOS 10.13 ( High Sierra) and higher, Intel 64-bit build, signed and notarized package.

Once downloaded, the software can be used in a standalone PC, Mac or a.Available for Mac, iPhone and iPad. Basic observabilityStatistical Process control: Statistics software helps in quality control which. You can also just use -pid=host if you want to start any other Docker container to inspect running processes. SQLite's code is in the public domain, which makes it free for commercial or private use.This gives you full access to the Docker VM.

Netflix has an excellent post called Linux Performance Analysis in 60,000 Milliseconds which recommends some good tools. Scientists always take multiple runs and calculate averages.Before diving too deeply into perf or eBPF to look for performance problems, it helps to know where to start. Use Markdown to format text with easy keyboard shortcuts, subtle syntax highlighting, word counters with live update, and much more.You can also keep track of statistics for averaged runs and experimental error. Draft a blog post, write that story or complete a school report wherever you are.

This is a good way to see if performance issues are due to container issues (cgroup throttling) or if theyвЂ™re due to host issues such as CPU saturation. Docker containers can be throttled by cgroup CPU limits, and when this happens a throttle counter will be incremented in /sys/fs/cgroup/cpu,cpuacct/docker//cpu.stat. It runs from the host, so you donвЂ™t need to do anything other than have Docker installed.Another helpful tool is the /sys/fs/cgroups directory. It displays each container and its CPU usage, memory usage, and other resource information. In my case, running pidstat and mpstat was sufficient to discover the cause of my slow builds.One helpful Docker-specific tool is docker stats, which is a top-like tool for monitoring the status of running Docker containers.

This involves either manually running apt-get install linux-perf immediately after spawning a shell or adding it to your Dockerfile.The commonly used perf record command dumps data to disk, so I also recommend mounting a volume to persist data across container runs and to do analysis on your host machine after profiling is done.I also installed tmux so I could run the command causing the problem in one pane, and run perf record in the other pane. This means that to get it running inside of Docker, youвЂ™ll need to pass the -privileged flag OR find a way to add CAP_PERFMON to your container which seems to be temporarily disabled by Docker.Please note that privileged containers are NOT recommended in production, so use this flag with caution!YouвЂ™ll also need to install perf in your container. Privileged containers, in order to work. Most of its functionality require root access, i.e.

IвЂ™m not sure if there is any difference between the two, but I used the linuxkit fork to be safe. However, it uses the Linux kernel git repository, and Docker for Mac uses a fork of the Linux kernel called linuxkit. These do not ship with the Docker Desktop for macOS VM, so I had to find a way to compile and install them which is the hardest part of getting BCC tools and bpftrace working.Fortunately, bpftrace has an informative guide on installing kernel headers which I used as a starting point to get eBPF working. EBPF tools such as BCC and bpftrace, especially for older Linux Kernels, rely on Linux kernel headers. BCC tools and bpftraceBCC tools and bpftrace provide a way to perform more in-depth performance analysis, but require a little bit more work to get up and running in the macOS Docker environment.In most cases, if you run Docker on a Linux host it shares the kernel with the Linux host. These make it really easy to visualize where your program is spending lots of time.

This would ensure that preparing the Linux headers would persist across container runs and the container would boot up fast. Dockerignore and mount it as a volume. Unfortunately my kernel version didnвЂ™t have a release tag in the linuxkit repository, so I had to do a checkout and clone instead of downloading a tarball.I also didnвЂ™t want to have to send the Linux kernel source (which is around 1GB) to the Docker daemon for each build, so I decided to add the 4.19.121-linuxkit directory to.

Why doesnвЂ™t runqlat work?I noticed that runqlat, a tool to detect CPU scheduler queue latency, wasnвЂ™t working. Could I just use the upstream linux.org 4.19.121 kernel instead of the linuxkit fork?Downloading a tarball would be much quicker than git clone. Why does -v /lib/modules:/lib/modules work correctly when invoking docker run from macOS?The directory doesnвЂ™t exist on my macOS machine, so IвЂ™m guessing it might fall back to the directory on the VM. QuestionsAlthough I was able to figure out how to run eBPF, there were some things I couldnвЂ™t figure out. We ended up fixing the issue by installing a version of lxml which had a pre-built libxml2 wheel which didnвЂ™t require compiling.So I didnвЂ™t end up needing eBPF in the end, but I still went through with the installation process as an educational exercise.
