Updating RabbitMQ Serv-

er for Resource Manager 4.2.2

service zenoss stop

4. Examine the RabbitMQ queues:

rabbitmqctl list_queues -p /zenoss

Your output should be similar to:

Listing queues ...

zenoss.queues.modelrequests.vmware 0

zenoss.queues.zep.migrated.summary 0

zenoss.queues.hub.invalidations.localhost:8789 0

zenoss.queues.zep.migrated.archive 0

zenoss.queues.hub.collectorcalls.localhost:8789 0

zenoss.queues.zep.rawevents 0

zenoss.queues.zep.heartbeats 0

zenoss.queues.zep.zenevents 0

zenoss.queues.zep.signal 0

zenoss.queues.zep.modelchange 0

...done.

Warning

Upgrading RabbitMQ will erase all exchanges and queries. All messages that have not been consumed

will be lost. If you notice any non-zero queues, then contact Zenoss Support before continuing.

If you have customizations or ZenPacks that are not Zenoss-supported and use RabbitMQ, ensure that

all of the messages in the relevant queues are consumed before continuing upgrade. Consult the provider

of the customizations for help regarding the sensitivity of lost messages.

5. Enter the following commands to quiesce RabbitMQ:

service rabbitmq-server stop

service rabbitmq-server status

You should see output similar to:

Status of all running nodes...

Error: no_nodes_running

6. Perform the RabbitMQ upgrade:

yum upgrade rabbitmq-server

7. Start the RabbitMQ server:

service rabbitmq-server start

8. Create a script to restore the RabbitMQ configuration for use with Resource Manager:

a. Create a file named configure_amqp.sh.

b. Add the following content to the file:

#!/bin/sh

RABBITMQ_USER=zenoss

RABBITMQ_PASS=zenoss

RABBITMQ_VHOST=/zenoss

configure_amqp() {

RABBITMQCTL="`which rabbitmqctl`"

if [ ! -z "$RABBITMQCTL" ]; then

local user_exists=`"$RABBITMQCTL" -q list_users | awk '{print $1}' |\

grep '^'"$RABBITMQ_USER"'$'`

if [ -z "$user_exists" ]; then

echo "Adding RabbitMQ user: $RABBITMQ_USER"

"$RABBITMQCTL" -q add_user "$RABBITMQ_USER" "$RABBITMQ_PASS"

local vhost_exists=`"$RABBITMQCTL" -q list_vhosts | awk '{print $1}' |\

grep '^'"$RABBITMQ_VHOST"'$'`

if [ -z "$vhost_exists" ]; then

echo "Adding RabbitMQ vhost: $RABBITMQ_VHOST"
