modbus polling and cpu overcharging - gdimaria - 20.12.2024
hi,
I have a LM whose CPU is often overloaded (it even restarts!).
I have analyzed every possible cause, including infinite loop scripts, but nothing.
The only thing I notice is a continuous telegram traffic from an external modbus gateway to which several devices are connected.
There are several telegrams frequently updated and/or repeated.
Could this be the cause of the overload?
Is it possible to monitor the CPU load trend to determine when it overloads?
Thanks in advance
Peppe

Install System load app and check which process is consuming max CPU/RAM.

I already done, those ones are always in pole position... enspecially nginx (there are several users simultaneously pointing their browser to LM).
