Re: [hobbit] Summary/Total data from several hosts

[Darren.Cotton (at) ses-astra.com]

Thanks Henrik,

I just having one small problem now - I can't send the data I get to
hobbit....

Output of the bb query is:
status server1.pusers green Wed Oct  3 12:40:00 UTC 2007\nConnected_Users :
175\n

DSLGWS="^server[12345]\$"
RESULT=0
bb 212.56.225.37 "hobbitdboard host=${DSLGWS} test=pusers fields=msg" | \
while read L
do
                NBUSERS=`echo "$L" | sed 's/.* //g' | sed 's/n//g'`
                RESULT=`expr $RESULT + $NBUSERS`
echo $RESULT
done

echo $RESULT

$BB $BBDISP "status Total-Users.pusers green `date`
Connected_Users : $RESULT
"

The first echo gives me the Total after each while/do ie.
186
370
527
677
839

but the second echo gives me 0. I've tried using export RESULT but can't
seem to be able to get the RESULT outside of the while/do statement.

I'd use the hobbitdboard query against the server:

DSLGWS="^server[12345]\$"
RESULT=0
bb 127.0.0.1 "hobbitdboard host=${DSLGWS} test=pusers fields=msg" | \
while read L
do
             NBUSERS=...whatever is needed to grab the number...
             RESULT=`expr $RESULT + $NBUSERS`
done

Grabbing data from the checkpoint file suffers from the fact that by
default it is only updated once every 15 minutes, so it takes a long
time for changes to filter through to that file. By using the
hobbitdboard command, you always get the latest data that Hobbit has.

Henrik
