Netgate SG1100 CPU Issue
-
Hi
History
I recently purchased a netgate sg1100 to run snort. some of the rules were causing problems which would not go away.
I uninstalled and tried Suricata but CPU usage was too high the app kept stopping.
So I uninstalled and went back to snort, adding rules 10 to 15 at a time. To date I have added emerging threat open rules and two thirds of snort subscription rules.I noticed at the dashboard CPU was hitting 100% and snort would crash. With snort not running I am hitting typically in the 80% range where previously I would see around 25% CPU usage.
I have tried reboots, disconnect from the power, makes no difference?Any Ideas on troubleshooting the CPU usage or do you think it is a hardware problem?
Thanks in advance

Hi,
You are aware that you took the smallest possible processor, to throw it at the applications/packages that are the biggest resource eaters ?
These packages might run, but with a very small, nearly useless ( ? ) rule sets."Big tasks needs big processors".

See what Diagnostics/System Activity shows. Note the Dashboard will use CPU cycles as it updates its widgets.

If you are checking from the dashboard in the GUI a significant proportion of it will be the dash itself, especially if you have a lot of widgets there.
At the command line run
top -aSH
to see what is running and how it's spread between the cores. Do that without having the webgui open in the background.Steve
