[SOLVED]egrep used lots of CPU,what did it grep ?

stephenw10

Ok so replacing egrep with ripgrep seems to work fine and should be significantly faster. However I'm only able to test with a relatively small number of states.

If you're able to test it install the ripgrep pkg:

pkg install ripgrep

Then edit /etc/inc/rrd.inc and replace the 5 instances of egrep with rg

I'll keep testing that here.

@stephenw10

perl -p -i -e 's/egrep/rg/g' /var/db/rrd/updaterrd.sh /etc/inc/rrd.inc

I kill and restart the updaterrd.sh.

The rg still cost lots of CPU every minus.

But for a shorter time?

Did he updater script get re-written? It would if you make any changes to the graph settings.

Yes,so if I did not use netdata to monitor the system very minus,I can not find it in the "top" command.

I did not "save view",just update graph.
