Here are some quick steps to install and get started with the discovery and monitoring using OpManager.
Before that, a quicker note on what OpManager can monitor. Just about anything on your network. It is enough if the device is reachable by OpManager.
The discovered devices are categorized as Servers, Routers, Switches, Firewalls, Printers, UPS, Wireless APs, and Desktops. And whats more! You can add your own categories.
OpManager starts as a service and the WebClient is automatically launched.
If OpManager is installed as a service, the WebClient is launched automatically. You can also open a new browser instance and connect to OpManager by typing the hostname and port number in the address bar as follows:
http://<hostname>:port -> number.
Example: The host name is opmanager-host, and the port number as 8060. Connect as:
OpManager accesses the remote devices using the protocols SNMP, CLI, or WMI. The credentials like the password/snmp community, port etc., may differ for different device types. Pre-configuring a set of credentials in OpManager helps applying them to multiple devices at a time, saving a lot of manual effort.
Type the device name in the search field on the right. You will find the device pronto! Here is an image showing you the search field.
OpManager automatically 'maps' the discovered devices into few broad categories like Servers, Routers, Switches, Desktops etc.
Don't worry if any of the discovered devices are not classified correctly. Here are the steps to change them:
To change category of a single device,
The page refreshes with the category changed.
To bulk-import devices into any infrastructure view,
The monitors for CPU, Memory, and Disk Utilization are automatically associated for the devices based on the device template definitions. For instance, for Linux servers, the default template has SNMP-based monitors associated. So, all Linux servers will have SNMP-based resource monitors associated. You will see the dial graphs for these three resources in the device snapshot page if SNMP is enabled.
Wait! Don't panic if you are not seeing the dial yet. You may not see the dials if SNMP is not enabled in the device. You have the option of either enabling SNMP, or associating CLI-based monitors. Here are the steps to associate CLI monitors.
You can configure thresholds for the following:
Resource Monitors, Service Monitors,Traffic Monitors :
Here are the steps to globally apply a threshold for a resource:
The template will be modified and change will be carried to all the devices..
You can also configure thresholds for individual devices by clicking the Edit icon against each monitor name. You will find the provision to specify the threshold here.
Device Response Time and Packet Loss Percentage:
You will need to configure the mail server settings, configure a notification profile, and associate it to the devices. This will notify you of specific faults through email.
The profile will be associated to all the servers. You will be notified when ever a threshold is violated for a server.
Define Device Templates
Define device templates to setup initial device configurations for existing and new device types.
Device Template: Specify the device type.
Vendor Name: Select the vendor. Click Add New to add a new vendor, and Save.
Category: Select the category for the device type.
Monitoring Interval: Configure the interval at which the device needs monitoring.
Device Image: Select the image for this device type.
System OID: Type the sysOID and click Add. Click Query Device for OpManager to query the device for the OID.
Select Monitor: Click this option to select the monitors.
Edit Thresholds: Click this option to edit thresholds.
Click Create button to create the new device template.
Monitoring requirement differs for different interfaces on a device. OpManager allows you to define configuration templates for interfaces of specific types. For instance, the configurations specified for an Ethernet interface can be applied to interfaces of this type across all devices, saving a lot of time.
OpManager comes with an in-built flash-based MapMaker. No more hassles of invoking a separate tool to create business views.
Click the small down arrow in the Maps tab or simply mouse-over. The default maps, with options to add more maps are seen.

Adding Business Views:
You can perform the usual operations of adding more device, adding links between devices, creating shortcuts, etc using the options provided on the left in the business views.
