Read the information and procedures in this section to learn about specific device management tasks, including: • Clearing heartbeat events

• Pushing configuration changes to the system • Locking device configuration

• Renaming devices • Remodeling devices

• Setting the device manage IP address

4.3.1. Clearing Heartbeat Events

If you have configured a device to send a recurring event that you have mapped to a heartbeat class, you can clear stale heartbeat events.

To clear the heartbeat events associated with a device: 1. Navigate to the device in the device list.

2.

At the bottom of the device overview page, select Clear Heartbeats from (Action Menu).

The Clear Heartbeats dialog appears. 3. Click Submit to confirm the clear action.

The system moves the heartbeat events for the device to event history and displays a confirmation message of the action.

4.3.2. Pushing Configuration Changes to Zenoss Core

When you make a configuration change, it is automatically propagated to all the remote collectors. If you think that your change has not been propagated correctly, then you can manually force a configuration "push" to the collectors.

Working with Devices

1. Navigate to the device in the device list. 2.

At the bottom of the device overview page, select Push Changes from (Action Menu).

The Push Changes dialog appears. 3. Click Yes.

The system pushes changes to the collectors and displays a confirmation message of the action.

4.3.3. Locking Device Configuration

You can lock a device's configuration to prevent changes from being overwritten when remodeling the device. Two levels of locking are available. You can lock the configuration from deletion and updates, or solely from deletion.

Note

Device locking prevents changes and deletion due to remodeling. It does not prevent manual changes and deletion.

To edit lock selections for a device configuration: 1. Navigate to the device in the device list. 2.

At the bottom of the device overview page, select Lock from (Action Menu).

The Lock dialog appears.

Figure 4.10. Edit (Configuration) Lock Dialog

3. To send events when actions are blocked by a lock action, select the "Send an event..." option. 4. Select the type of lock you want to implement or remove.

The lock or unlock action is implemented on the device, and the system displays a confirmation message of the action.

4.3.4. Renaming a Device

Because the system uses the manage IP to monitor a device, the device name may be different than its fully qualified domain name (FQDN). The device name must always be unique.

To rename a device:

1. Navigate to the device in the device list. 2.

At the bottom of the device overview page, select Rename Device from (Action Menu).

Working with Devices

3. Enter the new name for the device, and then click Submit.

The system renames the device and displays a confirmation message of the action.

4.3.5. Remodeling a Device

Remodeling forces the system to re-collect all configuration information associated with a device. Normally, the system models devices every 720 minutes; however, if you want to remodel a device immediately, follow these steps:

1. Navigate to the device in the device list. 2.

At the bottom of the device overview page, select Model Device from (Action Menu).

The system remodels the device. A dialog appears that shows progress of the action.

4.3.6. Resetting the Device Manage IP Address

You might want to reset the manage IP address if the IP address of a device has changed and you want to maintain the historical data at the original IP address. To reset the manage IP address of a device:

1. Navigate to the device in the device list. 2.

At the bottom of the device overview page, select Reset/Change IP Address from (Action Menu).

The Reset IP dialog appears.

Figure 4.11. Reset IP Dialog

3. Enter the new IP address for the device, or leave the field blank to allow the IP address to be set by DNS. 4. Click Save.

The IP address for the device is reset.

4.3.7. Deleting a Device

1. Navigate to the device in the device list. 2.

At the bottom of the device overview page, select Delete Device from (Action Menu).

The Delete Device dialog appears.

Working with Devices

3. Optionally change the selections to delete current events or performance data for the device. By default, events and performance data are removed.

4. Click Submit.

The system removes the devices and associated data (if selected), and displays a confirmation message of the action.

4.3.8. Dumping and Loading Devices

Zenoss Core allows you to export a list of your devices to a text file to import into another Zenoss Core instance. You can do this by using the zenbatchdump command.

You cannot use zenbatchdump on devices whose classes were defined in a ZenPack.

From the command line, use the command:

zenbatchdump > mydevicelist.txt

This command writes the names of your devices (including their device classes, groups, and systems) to a file named mydevicelist.txt.

To load these devices into another instance (or reload them into the same instance), while in the Zenoss Core instance where you want the devices to be discovered, run the command:

zenbatchload mydevicelist.txt
