garbage characters being returned in scripts

[Rick Garland]

Hi all:

 

Got a Nagios 3.2.3 server running on RHEL 5.5.

Installed plugins include pnp4nagios 0.6.13 & rrdtools 1.4.5

 

I  made some custom scripts that include the use of sar. A snippet;

 

WAITIO=`sar -u 1 3 | grep Average | awk '{print $4}'`

CRIT=50

                

echo "%waitio = $WAITIO | /=$WAITIO%;;$CRIT;0;100\r"

exit 0

 

When executing this script via nrpe to a Linux client, all is OK. When
the same check is performed against HPUX 11v2 or HPUX 11v3, 

there is garbage in the output and it gets placed into the XML file in
the <NAGIOS_LONGSERVICEOUTPUT>, this results in the parsing error

when trying to display the graph. Edit the XML file and take out the
garbage then the graph displays fine, until next update.

 

Here is the output after piped to cat -etv. 

[nagios at nagserver ~]$ check_nrpe -H hostname -c 'check_HPwait' | cat
-etv

%waitio = 2 | /=2%;;50;0;100^M$

$

M-(wM-}M-3M-^XwM-}M-3M-^X@^AM-_M-l@$

[nagios at nagserver ~]$

 

Anybody know where that garbage is coming from on HPUX? Anybody know how
to fix it? 

 

Many thanks
