High CPU usage...

[JaimeZX]

htop shows

grep -E reply.* is 203.205.179.205 /opt/var/log/dnsmasq.log /opt/var/log/dnsmasq.log1 /opt/var/log/dnsmasq.log2

is using 80%-97% CPU and there seems to be a "sister" task,

/opt/bin/grep -aw 192\.168\.X\.91 /opt/var/log/dnsmasq.log /opt/var/log/dnsmasq.log1 /opt/var/log/dnsmasq.log2

using about 20-33% CPU.

The second local IP seems to be changing with time.
What is going on?

uiDivStats?

Hit F5 in htop to show a tree view of what is calling the grep commands. Post a screenshot.

I imagine it’s contention between SkyNet and uiDivStats both running at :00 every hour.

Per your request. I like your theory, but I noticed it at :57 the first time...?

Can you page down in the second screenshot until the greps are visible?

Do you have a SkyNet debug or stats search running?

:facepalm: to the scroll-down. Please see below.

Also, yes. I often have the Skynet "debug" thing up in an SSH, but I've never noticed it driving high CPU usage before. You think I just overlooked it?

Edit: so I CTRL_C'd out of the Skynet debug and now the /grep thing has dropped to ~50% of processor...

I’ve never run the debug watch myself, but if your dnsmasq log files are large it could have an impact especially when uiDivStats is trying to read the same files.

It could almost be an option in SkyNet to disable that extra log searching, but if it finds the dnsmasq.log file, it enables it automatically.

In general, and with an infinite number of exceptions, debug modes can easily increase resource usage by 2x or 3x "normal" as they are meant for very brief intervals. No experience with this app in particular, but 2x cpu certainly wouldn't surprise me.
