[Xymon] hpux-meminfo.c patch

[Flack, Earl]

So the bad news is that swapinfo (on HP-UX 11iv3 ia64 at least) does not
take into account shared memory space memory utilization. 

We orginally tested the script on some idle servers with no databases
running at the time and it looked good there. After starting up a bunch
of oracle databases the output did not look right. Further investigation
showed that swapinfo was reporting an incomplete picture of memory, we
compared with kmeminfo and glance. Back to the drawing board for
scripts.

Hi Jason,

I was sent another solution back in December which replaces the
hpux-meminfo utility with a bit of shell scripting:

FREE=`/usr/sbin/swapinfo |grep ^memory |awk {'print $4'}`
FREEREPORT=`echo $FREE / 1024 |/usr/bin/bc` TOTAL=`/usr/sbin/swapinfo
|grep ^memory |awk {'print $2'}` TOTALREPORT=`echo $TOTAL / 1024
|/usr/bin/bc` echo Total:$TOTALREPORT echo Free:$FREEREPORT

(the original message is

 from Earl Flack)

Can you confirm if this shell script works OK for you ? 
I would much rather use standard shell-tools than a custom C program
that I have difficulty supporting.


Also, anyone with access to older HP/UX versions ? I would be most
interested to hear if Earl's shell version to get the memory info works
on other HP/UX versions as well.


Regards,
Henrik
