What is Server Management? What is SNMP? What is Virtual Server Management? What is Agentless Network Monitoring?

What Is Virtualization? Failed to establish connection with Web Server. Gracefully shutting down. Error Code Error in applying the OpManager 6. Gracefully shutting down Cause 1 While starting OpManager as 'root' user in Linux platform, the server goes down with the following message "Failed to establish connection with web server.

Solution Change the value of the parameter Group in httpd. Cause 2 If you are using Linux 8. This solution has worked for those using Fedora and Madrake Linux too. Solution Contact OpManager support with the details of the version installed including the Build number and email the license sent to you.

Can't create tables or not all the tables are created properly' error is displayed during OpManager startup Cause The database tables may be corrupted. Solution You can repair the corrupt tables. Error downloading client files from BE Cause This error occurs when the database tables are corrupted. Solution The database must be repaired and OpManager needs a restart. This repairs all the corrupt tables. After it finishes executing, run it once again to ensure all corrupt tables are repaired.

Devices are not discovered Cause This can happen if the ping requests to device get timed out. The DNS Server does not exist. Mapping So many 'Unknown' devices! How do I resolve this problem? How are Servers categorized in OpManager? Some servers are classified under desktops! How to define proper Device Templates? So many 'Unknown' devices! Causes What is an 'Unknown' device? A device is grouped under 'Unknown' devices category due to the following reasons: Does not have one of these protocols enabled.

In-correct user name and password or a user does not have the required privilege. For instance, WMI expects the user to have domain administrator's privilege. An Anti-virus or a Firewall does not allow OpManager to access. Network configuration that restricts access to some information on the systems in your network. Few security settings in case of Windows environment that dis-allows access. What to do? Despite this, if you face issues, troubleshoot as follows: Do you see a blue star in the device icon on the maps?

The device is still not classified properly? Simply edit the category from the device snapshot page. If SNMP agent is not running on the router, it will be classified as a server or desktop. You can verify this by the blue star appearing on the top left corner of the device icon for the SNMP-enabled devices.

To categorize the device properly, start the SNMP agent in the device. Rediscover the device with correct SNMP parameters. If the SNMP agent is running on the router and you still do not see the blue star in the device icon, then check if the SNMP parameters are properly specified during discovery. If not, rediscover the device with correct SNMP parameters. The router is discovered as a server or desktop if the IP Forwarding parameter of the device is set to false. In the ip table, click ipForwarding node.

Similarly, for switches and printers too, enable SNMP in the device and rediscover. How to define proper device templates to get the devices classified correctly? When should I create new templates? Scenario 1 Let us now assume you have purchased a Cisco series router. Click the Template name to modify an existing one.

OpManager is trying to contact the agent with incorrect credentials, such as a wrong password or wrong port. There is a delay and the queries sent by OpManager to the agents in the monitored devices are getting timed out or the devices are no longer in the network.

The particular OID for which the performance monitor is configured is not implemented in the device. Troubleshoot as follows: The possible reasons for the graphs not appearing are: The Resource monitors may not have been associated to this device. Associate the monitors. Check if SNMP is enabled properly on this device.

Check if the Agent is responding using the Mib Browser. If the device has just been added, wait for the first poll to happen. Following are the steps to troubleshoot: In the device snapshot page, scroll down to the monitors list. Click the Edit icon against a monitor. For instance, let us try the CPU Utilization monitor. Click the Test Monitor link in the resulting screen.

See if the monitor responds to the test request. If it does, you will see the dial graph. If there is an error message after step 1, it can be because of the snmp request to the cpu variable getting timed-out, or the oid may not be implemented in the MIB. To confirm the reasons mentioned above, invoke the tool MibBrowser. Load the Host Resource mib and query the oid. If there is a response for the query in MibBrowser, it implies that the OID is implemented and the dial not appearing can be due to snmp timeout.

The vendor must be requested to implement this variable for you. Read timed out. Exception in getting the command output: Timed out. Click the 'Passwords' link to configure the correct username and password to the device. Hit on the 'Test Credential' button in the password configuration screen to check if you are allowed authentication.

Verify the credentials by opening a remote telnet session to these devices from the machine where OpManager is installed. If the login credentials are correct, it is possible that the command used to retrieve the resource data does not execute on the device, or the output is different from the expected standard format. In this case, contact support with your details and you will be assisted with the configuration changes.

Unable to connect: Connection refused: connect The possible reasons for this error could be: Telnet is not enabled on the monitored server. Check and enable Telnet. The user name and password configured as part of the CLI credential is incorrect.

Configure the correct name and try configured. It might have been categorized incorrectly. Check and change the device type. Unable to connect: No route to host: The above error is encountered when the monitored device is not in the network. Unable to connect: Connection timed out: The above error too is encountered when the monitored device is not in the network. Login Parameter incorrect. Exception in getting the command output: Timed out This exception occurs due to the following reasons: The device is not in the network.

CLI connection is establised to the device but the device goes out of network at the time of gathering CLI command outputs from it. Click the 'Password' link to configure the correct username and password to the device. Ensure that you have configured the domain administrator user name and password for WMI Monitors if the device is in a domain. If the device is in a workgroup, it is sufficient to configure the device username and password. If you encounter an error such as Error Access denied, very the login credentials once again.

Remove and re-add the monitors. Check to see if the monitors are up WMI Monitors are not working. It always says 'error access denied' This error is encountered when the login credentials are incorrect. Follow the steps below to resolve: Verify if you have provided the domain administrator username and password to connect to the device as mentioned in the above tip. You should get the list of drives available in the device.
