Get Syntax Error when running a nagios Script

[Mahesh Alexander]

Hi all,

I am trying to run a script (attached) in a Server where I get a Syntax Error. I have used this script for all other servers without problems. HPUX version 11.23.

burbsdq1:/usr/local/nagios/libexec#./check_memory_hpux.sh -w 80 -c 90
./check_memory_hpux.sh[2]: FREEMB=: Syntax error
./check_memory_hpux.sh[2]: FREEMB=: Syntax error
./check_memory_hpux.sh[3]: * 20 / 100: Syntax error

I thought initially maybe due a different shell version but they`re the same.

Any idea why this is occurring?

Thx!

Hi:

You would produce these errors (at least in part) if the server on which you are running did _not_ have pseudoswap enabled. That is, you would be missing the "memory" line in the output of 'swapinfo -tam'.

If you like, on the failing server, run:

# swapinfo -tam

...and post that output.

Regards!

Hi James, you´re right, check the output:

burbsdq1:/usr/local/nagios/libexec#swapinfo -tam

Indeed the responsible variable for that is called

swapmem_on

and it was with value=0, so I had to changed it with the command

kmtune -s swapmem_on=1

Now we're waiting to reboot the server as it is needed to apply the changes.

Thanks James!!
