http://<hostname>:port -> number.
Example: The host name is opmanager-host, and the port number as 8060. Connect as:
Configure Discovery Credentials
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.
- Go to Admin Credential Settings
- Click New in this screen
- Configure the following parameters and click Add to add the credentials:
Credential Type: Select the relevant protocol.
Name: Configure a name for the credential and also provide the description.
SNMP Community & Port : For SNMP v1 and SNMP v2 protocols, configure the correct Read and Write community, and the SNMP Port.
WMI: If you select WMI as the protocol, configure the Domain Name, the user name, and the password. Example:- TestDomain\TestUser
Telnet/SSH: For Telnet/SSH, make sure you configure the correct login prompt, command prompt, and password prompt besides the user name and password to access the device.
VMware: To manage VMware's. Select the type as VMware, configure the exact HTTPs user name and password for ESX host along with the respective HTTPs web service port number and time outs(in seconds). You can also uncheck Auto VM Discovery option, if you do not want to monitor the VM's under the ESX Host.
- Click the Admin tab.
- Under Discovery, select Discover Devices.
- Select Use CIDR (Classless Inter-Domain Routing) option.
- Type the address of the network to be discovered. Example: 192.168.4.0

- Click Add Device to start discovery.
Find the Device
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.
Import the Devices
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,
- Go to the device snapshot page
- Click the Category field
- Select the correct category from the corresponding combo-box and wait.
The page refreshes with the category changed.
To bulk-import devices into any infrastructure view,
- Select Maps tab.
- Select the required infrastructure map from here, say Servers.
- Click Import link on the right
- Select the devices to be imported from the list and move to the right.
- Click Import Now.
Monitor CPU, Memory, Disk
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.
- Go to the device snapshot page.
- Click the Passwords link.
- Select the ‘Apply Global Parameters’ and select from the listed credential if you have already configured them.
Specify a new CLI credential for OpManager to authenticate to the device.
- Under Monitors à Performance Monitors, click Add Monitor..
- Select the CLI monitors for the resources.
- Do you see the dial graphs appear for some devices while few dont?
- Check if the device is SNMP-enabled. A blue star is shown on the device icon in the map.
- Click the device to see the device snapshot page. The 'sysDescr' here will show the system description if the device responds to SNMP requests
- Scroll down to the Monitorsà Performance Monitors section and click the Edit icon against the Monitor name.
- Click the Test Monitor link. When you click this link, OpManager queries the device for the data. If it responds, you should be able to see the dial.
If the Test Monitor does not respond, try the troubleshooting steps provided here: troubleshooting-guide.html
- If your devices are not SNMP-enabled, you can associate WMI-based monitors for all the Windows machines, and Telnet-based monitors for Linux machines as explained above. Pre-configured credentials come handy here..
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:
- Go to Adminà Device Template. Example: Linux.
- Scroll down the template and click Edit Threshold and specify the thresholds for all the resources.
- Click Apply.
- Select the devices for which this change should be applied, and click Apply again.
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:
- Select the device for which you want to configure the thresholds
- Click Edit icon in the ' Response Time' and ‘Today’s Packet Loss’column to configure the thresholds.
Configure an Email Alert
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.
- Select Admin -->Mail Server Settings
- Configure the Mail server name and port number
- Configure the email id to which a notification must be sent when a fault occurs
- Click OK to save the settings.
- Select Admin --> Notification Profiles
- Click ‘Add New’ option against Email Profiles
- Type the profile name, to and from email address.
- Select the alarm variables that you want to see in the email and click Save.
- Click Associate link on the right to associate the profile to devices.
- Select the Profile and click Next.
- Select the fault criteria for which you need to be notified. For instance, if you want to be notified of threshold violation, select 'Threshold rule is violated'. Click Next
- Select the devices or the category of devices for which you want to be notified. For instance, if you want to be notified of threshold violation for all Servers, select Server category from the combo-box. Click Next.
The profile will be associated to all the servers. You will be notified when ever a threshold is violated for a server.
