Hi,

I don’t uderstand why the memory usage by application is showing that netdata is using 40GB of ram instead of 2…

I notice also that the labels of the graphs are wrong.

Second graph is not user group, but users.

Hi, it looks like sql from User Groups falls into netdata from Users. You can check per group/user running processes using ps:

  • per group: ps -g netdata / ps -g sql
  • per user: ps -u netdata / ps -u sql

I notice also that the labels of the graphs are wrong.

Good catch, fixed in 13621. Thanks!
