Let's build a simple system calls monitoring dashboard using bpftrace and streamlit

• bpftrace

  24 7,647 0.0 C++

  Discontinued High-level tracing language for Linux eBPF [Moved to: https://github.com/bpftrace/bpftrace]

  

This solves some of the issues we had with ptrace based implementations. Recently iovisor project came up with a tool called bpftrace which can be used as an alternative to strace with more number of additional features. bpftrace uses eBPF for core tracing and provides user-space tools to harvest the tracing data. To understand more about bpftrace read this reference guide. bpftrace is not restricted just to system calls tracing, we can also use it to trace Disk I/O operations, network operations, CPU utilization etc. Since bpftrace supports eBPF at it's core, we can use BPF scripts to write our own tracing scripts easily. If you are interested, have a look at some of the cool tracing scripts built using BPF, all these scripts can be readily used with bpftrace.

• streamlit

  255 31,506 9.8 Python

  Streamlit — A faster way to build and share data apps.

  

Now that we are receiving the system call counts every 5 seconds, let's use it to build a live dashboard. There are hundreds of tools and libraries available for building dashboards these days, I decided to go with streamlit - this python framework will allow us to spin up a dashboard with less code (I wanted to keep it as simple as possible). To get started with streamlit, make sure you have python 3.0+ (usually this will be installed by default on many Linux distributions). We will install streamlit using pip.

• SurveyJS
