Hi,
The memory plugin is, probably for good reasons, removed from collectd (ref #3414)
and
http://dev.nethserver.org/issues/3414
Stubborn and hardheaded as some people call me (i’d like to opt just to have a strong own opinion),
put this plugin back in by editing /etc/collectd.d/00plugins.conf
It running just fine for two day’s now:
What where reasons to remove it?
I can’t check it now but… This looks very strange! 
Are you sure the memory plugin is not already configured somewhere else?
/cc @dev_team
The only plugins for collectd are in Reports → Graphs.
But @giacomo already said why in issue 3414, i think.
Maybe I’m wrong but threshold is not memory!
Sorry!
My FAULT! 
Exactly my thoughts…
As you sad before: its team work 
I don’t think you’re wrong at all @GG_jr ! I don’t get why @giacomo removed those lines for memory plugin too. I’m sure he can help us tomorrow!
I checked now, also on NS 6.8 final (in production) and the memory plugin isn’t there.
The memory plugins has been removed during the migration process, mainly because it was useless 
The memory is always full on a linux machine and the graph doesn’t show really useful information.
If anybody agree we should add it back, I will open a new issue 
(But, since now, nobody noticed it was gone! 
)
Let agree to disagree.
Exually because linux always reports the memory to be full it’s shows useful information:
green on the bottom : memory allocated to the kernel (cutting some corners here 
)
red : memory used by applications (EDIT: the allocated memory to the apps is missing in this graph 
)
blue : buffers and cache
green on top : free (“headroom” before swapping more pages)
In general i really start to worry if the red line (=kernel + apps) uses more then 50% in a idle state;
if there is a lot of disk I/O even on more then 25%.
EDIT 3 : 
I admit it’s with nethserver-arm in mind, where memory resources are limited and leaking apps/drivers are not that uncommon…
Take a look at this:
Indeed! 
Anytime my friend! Anytime! 
Do you remember my “Letter to Santa” or my “wishes list”, or …? A lot of things to ask! How much can you take?
