In this guide, you are going to learn how to install sampler shell command visualization tool on Linux. Sampler<\/a> is a tool for shell commands execution, visualization and alerting.<\/p>\n\n\n\n

Install Sampler Shell Command Visualization tool on Linux<\/h2>\n\n\n\n

Sampler is available as a binary that can just be downloaded and installed by placing it on the\u00a0standard Unix directory for storing executable files.<\/p>\n\n\n\n

Download Sampler Binary<\/h3>\n\n\n\n
wget https:\/\/github.com\/sqshq\/sampler\/releases\/download\/v1.0.2\/sampler-1.0.2-linux-amd64<\/code><\/pre>\n\n\n\n
Install Sampler<\/h3>\n\n\n\n
Installing Sampler on Linux is as simple as copying the binary to \/usr\/bin<\/strong> directory renaming it as follows.<\/p>\n\n\n\n
cp sampler-1.0.2-linux-amd64 \/usr\/bin\/sampler<\/code><\/pre>\n\n\n\n
Next, make the Sampler binary executable.<\/p>\n\n\n\n
chmod +x \/usr\/bin\/sampler<\/code><\/pre>\n\n\n\n
Usage of Sampler<\/h3>\n\n\n\n
With Sampler, you can execute various shell scripts that gets you metrics and output them for visualization. Sampler is configured with a simple YAML file and hence, you need to define your shell commands in YAML configuration file.<\/p>\n\n\n\n
Once you have created you shell commands configuration file, you can then pass it to Sampler for execution with -c<\/strong> option as in, sample -c config.yml<\/strong>.<\/p>\n\n\n\n
Creating Sample Configuration File<\/h3>\n\n\n\n
To begin, let us create a simple configuration file for visualizing a few shell commands. For example, to visualize the CPU usage, system uptime, number of logged in users, memory usage, you can create an YAML configuration like as shown below;<\/p>\n\n\n\n
vim config.yml<\/code><\/pre>\n\n\n\n
sparklines:\n  - title: CPU usage\n    position: [[42, 12], [38, 16]]\n    rate-ms: 200\n    scale: 0\n    sample: ps -A -o %cpu | awk '{s+=$1} END {print s}'\ntextboxes:\n  - title: Memory Usage\n    position: [[1, 27], [79, 15]]\n    rate-ms: 200\n    sample: free -h\n  - title: Logged in Users\n    position: [[0, 12], [41, 16]]\n    rate-ms: 200\n    sample: w\nasciiboxes:\n  - title: System Uptime\n    position: [[0, 0], [80, 12]]\n    rate-ms: 500\n    color: 43\n    sample: uptime | cut -d',' -f1<\/code><\/pre>\n\n\n\n
To view the visualization, simply run Sampler with your configuration file as;<\/p>\n\n\n\n
sampler -c config.yml<\/code><\/pre>\n\n\n\n
\"Sampler<\/a><\/figure>\n\n\n\n
That is just it on simple Sampler shell command visualization. <\/p>\n\n\n\n
