# Plugin to monitor Memory usage inspired by cpubyuser
|
|
#
|
|
# Usage: Place in /etc/munin/plugins/ (or link it there using ln -s)
|
|
# Add this to your /etc/munin/plugin-conf.d/munin-node:
|
|
# [membyuser]
|
|
# user root # required if /proc can't be read from by any user!
|
|

|
## 2012-05-23 Sebastien Campion
|
|
# changed on 2019-08-30 by pcy <pcy@ulyssis.org>:
|
|
# - change category from 'memory' to 'system' (so it appears next to cpubyuser)
|
|
# - use rss instead of vsz
|
|
# - more robust username enumeration
|
