PRTG Catches Network Issues Before They Cause Downtime
Threshold-based alerts flag problems early, so your team can act before users notice, not after.
Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.
Backup solution based using git and rsync next level
Etckeeper-ng is a bash script which uses git and rsync awk sed and find to create a backup directory of your /etc linux directory.
It is easy to configure. The default configuration should work on most boxes. Just make sure you have git rsync and all the other requirements installed.
When you use the etckeeper-ng the first time open a terminal and type "etckeeper-ng init" to create your first initial backup or "etckeeper-ng help" to show the help for this script.
