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?
