xymon replication or clustering

[Root, Paul]

The hobbit-alerts.cfg entry for the secondary:

HOST=<PRIMARYSERVER> COLOR=red SERVICE=bbd,conn
        SCRIPT /usr/local/scripts/hbtSecondaryTakeOver <EMAILADDRESS>
        MAIL <EMAILADDRESS>


The hbtSecondaryTakeOver script:

echo "Starting at `date`, $BBHOSTNAME . $BBSVCNAME" >/tmp/blah
MESSAGE="Hobbit: $BBHOSTNAME's $BBSVCNAME service is $BBCOLORLEVEL. Secondary taking over"
export HOST=`/usr/bin/hostname`
export USER=hobbit
echo "mailing: $RCPT \"$MESSAGE\"" >> /tmp/blah
echo  $MESSAGE | /usr/bin/mail $RCPT
HETC="/home/hobbit/server/etc"

cp ${HETC}/hobbit-alerts.cfg.primary ${HETC}/hobbit-alerts.cfg
The hobbit-alerts.cfg entry to release (would go in hobbit-alerts.cfg.primary)

HOST=iadhbtp1 COLOR=red SERVICE=bbd,conn RECOVERED
        SCRIPT /usr/local/scripts/hbtSecondaryRelease <EMAILADDRESS>
        MAIL <EMAILADDRESS>

And the release script:

echo "Starting at `date`, $BBHOSTNAME . $BBSVCNAME" >/tmp/blah
MESSAGE="Hobbit: $BBHOSTNAME's $BBSVCNAME service is $BBCOLORLEVEL. Secondary turning down"
export USER=hobbit
echo "mailing: $RCPT \"$MESSAGE\"" >> /tmp/blah
echo $MESSAGE | /usr/bin/mail $RCPT
HETC="/home/hobbit/server/etc"

cp ${HETC}/hobbit-alerts.cfg.secondary ${HETC}/hobbit-alerts.cfg


You'll need to adjust things like, machine names, file/directory locations/name, and email addresses.

Also, You don't want the Release script to run on the primary, so either don't have it there or have some logic in the script that stops execution if it's not the right machine (like if [ "$HOSTNAME" != "<secondaryserver>"] ; then exit fi)

I have a secondary server watching the primary. It has 1 think to do in hobbit-alerts.cfg, watch the primary. If the secondary looses contact with the primary it will run a script.

That script is to copy in the primaries hobbit-alerts.cfg file in place. It is put on the secondary automatically with rdist.

Also, in the primaries hobbit-alerts.cfg file, there is a watch that looks for a recovery, at which time, another script is run to reverse the process.

Pretty simple

Hi,

We have one xymon in our Head Office, and other one in branch office.
In my Head office, we want to have 2 xymon to replicate result, if one failed, the other take place.

An employe have start something, but he left month ago. I see I the hobbit he did, this line in bb-hosts :
                summary  Hobbit-PRD.All 172.30.1.1 http://hobbit/hobbit
                group servers
                127.0.0.1              Hobbit-PRD        # bbd http://Hobbit-PRD/

So the big question is, it is possible to do this ? Can we have to xymon than are in "cluster"

And if we want to get our branch office?

thx

David Raymond
