System Load Variable - pioneersteffen - 05.10.2024
Hi @all,
is there an option to call the actual system / processor load in a script?
I haven’t found anything in the LUA reference manual.
Many thanks for your help!
Best regards
Steffen

Resident script with a 60-second sleep interval.
Create two 2-byte objects and name them CPU and Memory.
Code:
load = io.readfile('/proc/loadavg'):split(' ')[ 1 ]
memtotal = data:match('MemTotal:%s+(%d+)')
memavail = data:match('MemAvailable:%s+(%d+)')
memusage = math.floor((memtotal - memavail) / memtotal * 1000) / 10
log(load, memusage)
grp.update('CPU', load)
grp.update('Memory', memusage)RE: System Load Variable - admin - 07.10.2024

Hi Fahd,
hi Daniel,
many thanks for your help! It works now for a overall performance log.
Is it also possible to log a specific process what memory and CPU it consumes?
Many thanks for your help!
Best Regards

What process do you want to monitor and why?
RE: System Load Variable - pioneersteffen - 07.12.2024
Hi Admin,
I looking for a really strange memory issue.
Out of: /proc/meminfo I extracted the log over time and there is a continuous increase of AnonPages and Inactive(anon).
Now I want to analyze further what process is the reason for it. How can I do that?
Many thanks for your help!
Best regards
Steffen
P.S.: Here are some logs
