I have 5 hosts on which I have script monitoring connected users. This is then sent to hobbit and as a result I have 5 separate entries which I then want to total on the server.
Currently I am parsing the tmp file to get the number of users as follows:
DSLGWS="server1 server2 server3 server4 server5"
SERVICE=Total-Users
BBPROG=bb-pusers.sh; export BBPROG
RESULT=0
COLOR="clear"
BBTMP="/usr/lib/hobbit/server/tmp"
for USERS in $DSLGWS
do
if [ -f $BBTMP/hobbitd.chk ]; then
NBUSERS=cat $BBTMP/hobbitd.chk | grep pusers | grep $USERS | sed 's/.*: //g' | tr -d '\\' | sed 's/n.*//g' | bc
RESULT=echo "$RESULT+$NBUSERS" | bc
else
echo "Unable to find "$BBTMP/hobbitd.chk" Sending 0 total
users"
RESULT=0
fi
done
MACHINE=$SERVICE
$BB $BBDISP "status $MACHINE.pusers $COLOR date
Connected_Users : $RESULT
"
Now this works but I think it is an ugly way of going about it - Is there another simpler/better way of going about this that I cant see.

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.

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've had the same problem occasionally. I don't know what the "proper" solution is, but this works for me:
RES=`bb 212.56.225.37 "hobbitdboard host=${DSLGWS} test=pusersfields=msg" |
while read L
do
NBUSERS=\`echo "$L" | sed 's/.* //g' | sed 's/n//g'\`
RESULT=\`expr $RESULT + $NBUSERS\`
echo $RESULT
done`
echo $RES
I.e., enclose the whole while loop in backticks, and also escape all backticks within the outer set. *Anything* echoed inside the outer set of backticks becomes part of the value of $RES, which makes debugging tricky.
T'ain't pretty, but it works and it's all in shell...
