Ns7b2 collectd memory plugin removed (ref #3414)

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! :fearful:

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!

There is a reference about memory module.
That’s why I was convinced I’m right, but … I was wrong.

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 :blush:

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 :slight_smile:
(But, since now, nobody noticed it was gone! :grin:)

Let agree to disagree. :slight_smile:

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 :open_mouth:)
red : memory used by applications (EDIT: the allocated memory to the apps is missing in this graph :cry:)
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 : :grin: I admit it’s with nethserver-arm in mind, where memory resources are limited and leaking apps/drivers are not that uncommon…
