Adding a collector

4. Log in to the master host as user zenoss and enter the following command. Substitute the fully-qualified domain

name of the collector host for collector-host:

cat $HOME/.ssh/id_rsa.pub | ssh -l root \

collector-host "cat - >> /root/.ssh/authorized_keys"

The ssh command prompts you to confirm the connection.

5. Enter yes.

The ssh command prompts you for the password of the root user on the collector host.

6. Enter the password.

The ssh command invokes cat to append the RSA public key of the zenoss user on the master host to the authorized

keys file of the root user on the collector host. In addition, ssh adds the collector host to the known hosts file of

the zenoss user on the master host.

7. Log in to the Resource Manager browser interface as a user with ZenManager or Manager permissions.

8. Click Advanced > Collectors.

The browser displays the deployed hubs and collectors.

9. Select the hub through which the new collector's data will flow.

10.From the action menu next to Zenoss Collectors, select Add Collector....

The Add Collector page displays.

11.Select root user SSH keys.

12.Provide values for the following fields:

• Collector ID, the logical name of the collector.

This name is used as the prefix for Resource Manager daemons on the collector host. For example, if the name

is denver, then the SNMP monitoring daemon is denver_zenperfsnmp.

• Host, the fully-qualified domain name or IP address of the collector host.

13.Click Add Collector.

Resource Manager submits the "Add collector" job to the jobs queue. Upon completion, the browser updates the

Advanced > Collectors page with an entry for the new collector.

3.2.4. Zenoss user SSH keys

Perform these procedures to install a new collector using the SSH authentication keys of the zenoss user on the master

host. (Someone must have root privileges on the collector host to perform the first procedure.)

3.2.4.1. Preparation tasks

1. Log in to the collector host as root, or as a user with superuser privileges.

2. Remove conflicting messaging systems.

a. Determine whether Matahari or Qpid are installed.

rpm -qa | egrep -i "matahari|qpid"
