<div dir="ltr">Hi,<div>the load on linux systems is considered high when it is higher than number for CPUs seen by the system. The value is a number of processes waiting in queue to get CPU time (even if it is waiting for disk I/O), not a utilisation in percentage so 50/55 is too high unless you have a server with 40-48 CPUs/cores. My default setting is "LOAD 5.0 10.0" for all machines with 4 CPUs.</div>
