Hi Ralph,

I don't think there is something like that in hobbit. But you might want to create a custom script including something like (perl)

Aktuelles Datum

$t0 = time; $ZEITSTEMPEL = localtime($t0);

##################################################################

Check Website

##################################################################

system("wget -o /dev/null -O /tmp/ \"$REQUEST\" 2>/dev/null");

Bestimmung des Ergebnissstatuses aus der Antwortzeit.

$elapsed = time - $t0; if ( $elapsed <= 6 ){ $STATUS = $OPTIMAL; } elsif ( $elapsed <= 12 ){ $STATUS = $WARNUNG; } else { $STATUS = $FEHLER; }

Thanks for that. If I have to I'll do something similar in bash with curl, as I'm more familiar with that:

elapsed=curl -s -S -L -w '%{time_total}' http://server.domain.com

which gives me time in seconds, with millisecond resolution.

I'd like to get the graphs as well, without having to fiddle with the message format.

OK, so it wasn't as hard as I thought to replicate the http built-in test. This script does everything I need right now, though it could do with refining:

#!/bin/bash

Format in bb-hosts: 1.2.3.4 server.domain.com # httpplus:warn:alert

warn and alert values are expressed in milliseconds, just because we can

bbhostgrep httpplus\* | while read line do set $line TESTHOST=$2

httpplus=`echo $line | $SED -e 's/^.* httpplus://' -e 's/ .*//' -e 's/:/

/g'` set $httpplus WARNVAL=$1 ALERTVAL=$2

URL="http://$TESTHOST/"
res=`/usr/bin/curl -I -s -S -w 'Seconds:\t%{time_total}' $URL`
ret=$?

elapsed=`echo "$res" | $GREP Seconds: | $SED -e 's/^.*        //'`
elapsed=`echo $elapsed \* 1000 | /usr/bin/bc | $SED -e 's/\..*//'`

if [ "$elapsed" -gt "$ALERTVAL" ]; then
  COLOR=red
  STATUS="Server too slow"
elif [ "$elapsed" -gt "$WARNVAL" ]; then
  COLOR=yellow
  STATUS="Server response degraded"
else
  COLOR=green
  STATUS="OK"
fi

MACHINE=`echo $TESTHOST | $SED -e 's/\./,/g'`
LINE="status $MACHINE.http $COLOR `date`: $STATUS

&$COLOR $URL - $STATUS

$res

WARN at ${WARNVAL}ms, ALERT at ${ALERTVAL}ms"

$BB $BBDISP "$LINE"

done

It assumes that it's OK to use the hostname field for the url, and picks up the WARN and ALERT times from the "httpplus" tag in the bb-hosts file. It also ignores any curl errors, such as timeout due to the server not responding.
