Nagios memory percentages

[Machiel Richards]

Hi

 

  I am trying to use this option but the issue I have now is with the
following:

 

The output from the /proc/meminfo is  as follows:

 

            MemFree:      206788 kB

 

   However, when I try to use cut in order to only get the numeric
value, the output I get back does not work that well as it still
includes the <spaces> infront of the numeric value as well as the kb at
the end...

 

            I have even tried this with free and the same result....

 

            What should I use as delimiter to the cut command?

 

            Any other suggestions on how to only get the numeric value?

 

            Commands used with output:

 

cat /proc/meminfo | grep MemTotal | cut -f 2 -d ":"

 

output :

 

      2067884 kB

 

 

  As you can see the spaces are all out of place.....

 

      I have also noticed that when using a space as delimiter and
counting the spaces to the value, then you get the result, however if
the numeric value increase by one digit (i.e. from 6 digits to 7 digits
for instance) then the amount of spaces change and the program does not
work.

Looc at the /proc/meminfo file and the vmstat command.

Divide memory parameter (free, used, whatever) by total memory, multiply
by 100 and you have percent.

Hi Everyone

 

  Maybe someone can assist me, but this may be a more linux specific
question than Nagios even though related to Nagios.

 

   I need to monitor the memory usage in percentage on Nagios and would
like to rather write my own scripts for this.

 

 

   I know there are snmp versions of this to do the job for me, however
I do not want to complicate the systems with too many clients running on
them.

 

Currently we are using the normal nrpe to connect to the systems and run
scripts remotely, however we do not have one to monitor the memory.

 

            On the web there are a lot of references to the snmp
commands but as all the systems are production and we might be having a
couple of upgrades soon, I would like to rather keep it simple and only
run one client on it for all Nagios connections.

 

 

            My question is this... I can use the command free to get the
amount of memory , used, free etc... 

 

            How can I write this into a script to display as
percentages... is there another command I can use or maybe an option
that I do not know about?
