Okay, so we need to analyze memory usage, 3 minus M is what we need to do.
Now what can we see?
Well, we can see that there is absolutely no problem at all.
And that is because there is a 1332 use and 780 Mb free, that alone is more than 20%.
And available, that is more than 60%, so nothing to worry about at all.
But still, we need to analyze what is going on here, and in order to do so, you need to
involve grep minus I active on proc meminfo, because the specific question was to get information
about swap usage.
Now there we get very interesting information.
We have active anonymous memory set to about 1 GB, and inactive, there is no inactive memory.
So why are we so interested in inactive memory?
Well, that is because if you are reaching a situation of memory shortage, inactive memory
can be moved to swap.
So the question is, do we have enough swap to accommodate the inactive memory?
Well, certainly at this point, we do, because there is no inactive memory.
But related to this, we might be interested in the uptime command, and there we can see
that this system has not been up for such a long period, and that explains the absence
of inactive anonymous memory.
This will definitely change if really something is happening on the system, and then this
is what you should be looking at.
