generates very detailed e-mails with graphs and statistics on what was happening on you server during the last days
This script is written in julia language. You need to install julia 1.3 or newer, for example using
sudo add-apt-repository ppa:jonathonf/julialang
sudo apt-get update
sudo apt install julia
Optionally, you can also install pngquant to compress the pngs and send smaller emails: sudo apt install pngquant
To install and build the dependencies of julia, run julia install.jl. If you want to run this package as cronjob, make sure to run the install.jl from the same user as the cron job.
Currently, the only supported backend is sysstat. So make sure sysstat, sar and sadf are installed and properly configured.
Run julia server-diary.jl. It will generate a file stats.email which is a multipart-html-email with images. You can send it using sendmail -i -t < stats.email.
Old graphs are archived in the stats folder. Feel free to delete them if they become too many.
