  • I hooked up Zabbix to our existing Mango 3.7.7 installation and noticed that the CPU usage was oddly high and following an odd pattern:

    5bb04cdb-14d8-40b3-af52-6a9f2fb705b6-image.png

    On every hour and half hour, CPU utilisation drops to 3% for 6 minutes and then ramps back up to 60%.
    The timing is actually three minutes before the 00/30 mark until 3 minutes after.
    Looking at the mango process in htop confirms the behaviour.

    The mango installation isn't particularly heavy, 86 data points.
