error in if_ plugins for Solaris node

The 1.3.4 code doesn not work on the solaris machine I have available. What output do you get from this command on your machine (substitute rtls0 with your interface name)?

$ kstat -p -n rtls0 -s '/^[ro]bytes$/'
link:0:rtls0:obytes     18825
link:0:rtls0:rbytes     36763
unix:0:rtls0:obytes     0
unix:0:rtls0:rbytes     0

OpenSolaris? (5.11) here.

Hi,

the code in 1.4.2 was made for OpenSolaris?. In OpenSolaris? the kstat command has the switch -m, which does not exist for kstat in Solaris 10 or earlier.

I suggest the following code snippets (they're maybe not the most efficient, but they make clear, what is meant):

SOLVERSION=`uname -r | awk -F. '{print $2}`


...


if [ "$1" = "suggest" ]; then
        if [ -x /usr/bin/kstat ]; then
                if [ $SOLVERSION -le 10 ]; then
                        kstat -p -s '/^rbytes$/' | awk -F: '{ print $3 }'
                elif [ $SOLVERSION -eq 11 ]; then
                        kstat -m link -p -s '/^rbytes$/' | awk -F: '{ print $3 }'
                fi      
                exit 0
        else    
                exit 1
        fi
fi


...


if [ $SOLVERSION -le 10 ]     # Solaris 10 and earlier
then
        kstat -p -n $INTERFACE -s '/^[ro]bytes$/' | awk -F: '
        {
                split($4, four, "\t")
                print four[1] ".value", four[2]
        }'
elif [ $SOLVERSION -eq 11 ]   # for OpenSolaris
then
        kstat -p -n $INTERFACE -m link -s '/^[ro]bytes$/' | awk -F: '
        {
                split($4, four, "\t")
                print four[1] ".value", four[2]
        }'
fi

The first part handles the "suggest" section, the last one is for reading the statistics.

I attached a patch for that (which should be verified of course).

Patch for if_.in

Correction: kstat in Solaris 10 has the switch "-m" but not the module "link". So the output of "kstat -m link ..." is empty on Solaris 10. This is just for info, it doesn't effect the patch.

I've got some Solaris hosts so I made a proper fix for this and committed it to trunk, r3906 (I'll push it to 1.4 stable too). Instead of sniffing the OS version (there's no guarantee that a version of Solaris 11 won't behave like Solaris 10 again), I put in some more regex magic to the kstat calls.

I've tested it on Solaris 8, 10, and OpenSolaris?. Re-open the bug if there's still problems.

Anyone who loves films is likely to love film downloads, too. The very fact is that this pattern is turning into a giant one and it is nice for those who wish to create giant collections without having to dole out high dollar or premium house area to do so.
