• Halloween is coming! To celebrate the occasion, we dusted off a couple of old skins, and even created a brand new one (Pixel).
    To get into the festive spirit, install the Skins extension.
  • The new Python extension is now available. It allows customers to deploy and manage WSGI-based Python applications on their websites directly from Plesk.
  • The Plesk Mobile apps for iOS and Android and the Plesk Mobile Center extension have been deprecated, and are no longer available for new installations. In Plesk Obsidian 18.0.84, the Plesk Mobile Center extension will be removed from servers during the upgrade, and the Plesk Mobile apps will lose their server management features.
  • The Social Login extension has been deprecated and will be removed in Plesk Obsidian 18.0.84. After that, it will no longer be possible to log in to Plesk with a Google, Facebook, GitHub account, or with a passkey. Plesk usernames and passwords, as well as logging in with a WebPros Account, are not affected.

MySQL memory usage alerts

Hello!

After installing the Android app on my phone, i noticed the alerts tab is showing yellow and red for MySQL memory usage. (I can't seem to find any similar information in the web browser based control panel.) The stats tab shows there should probably be enough memory available on the server. (Screenshots attached)

Google suggests this as a top hit for addressing MySQL memory issues, but wanted to touch base here first before attempting to tweak:

Just looking for someone to point me in the right direction. I know memory management can open up pandoras box.

Version Plesk v12.5.30_build1205150826.19 os_Ubuntu 14.04
OS Ubuntu 14.04.3 LTS


Thank you!!!
 
Can anyone offer a quick thought on this?

The installation only has 15 very small, low-traffic Drupal sites and server shows roughly 40% memory still available. Does Plesk/MySQL really need manual memory management tweaks for this even for such a relatively small setup?
 
Hello meech,

As far as I can see from screenshot there is enough RAM memory on the server. Changing Mysql memory usage levels to yellow and red can be caused by peak load on the server or warning levels are set to low values.
In first case attempt to increase virtual memory size. In second correct alarm levels for Health Monitor by using KB article: https://kb.odin.com/en/124153
