Netdata endless torrent of warning emails
« on: April 30, 2019, 04:37:15 PM »
Following recent CWP updates, netdata service was installed. Since then, I've been getting an endless torrent of warning messages about just about every other service plus RAM usage on my server. Messages suggest the server is constantly over loaded. But I run a couple of small, low traffic wordpress sites on a Linode, with 2GB RAM and plenty of disk space remaining so I'm thinking it really shouldn't be suffering from a lack of resources.. So then what's going on here? I'm running CWPpro version: 0.9.8.807 on Centos 7

Has CWP messed up the server or Netdata configuration? Why am I suddenly faced with this problem?

Example netdata messages:

Attaching here some screen shots of netdata graphs from my server. httpd, python.d.plugin, email and sql are showing the highest usage or trigger events. But maybe that's the result of Netdata itself running? My server is configured with Spamhause blacklist check, CSF firewall, Maldet and RKhunter scanners and various other security measures. All checked today and no security breaches found and no entries on any blacklists. So.. again, 1 core, 2GB Ram server running a few low traffic (visits per month in the hundreds) wordpress sites. Why would the server be at all taxed? What's going on here? Any tips would be appreciated.

See my other post on this issue: http://forum.centos-webpanel.com/addons/netdata-installed-by-itself/msg22922/#msg22922
I got there an answer on how to uninstall it.
Not only it bombarded me with emails, but it was using 100% of the resources!
