1. What are the System requirements for ManageEngine OpUtils 4?
Supported JDK - JDK 1.5 and above is required for ManageEngine OpUtils.

Platforms - ManageEngine OpUtils is platform independent and supports operating systems such as - Windows 2000, Windows NT, RedHat Linux 7.x and above.

Supported Browsers for OpUtils are - Internet Explorer 5.5 and above, Netscape 7.0 and above, and Mozilla Firefox 1.0 and above.

2. Can I install OpUtils in one machine and access it remotely?
Yes. You can install OpUtils in one machine and access the tools from any web browser.

3. What do you mean by Free, Standard, and Professional editions?
Free edition: The free edition of the OpUtils contains the 15 tools of the total 48 tools of the product. At any point of time users can upgrade to the Standard/Professional edition of the product.

Standard edition: The standard edition of oputils contains 38 tools of the total 48 tools of the product. At any point of time users can upgrade to the Professional edition of the product.

Professional edition: The Professional edition of the OpUtils product includes all the 48 tools of the product.

For details of the tools in Free, Standard, and Professional editions, refer to the Tools Matrix.

4. What is meant by "Community"?
Community refers to the SNMP Community string of the device being queried. This will be required in tools that used SNMP to get the required details. In most cases, a read-only community string is sufficient.

5. What do you mean by a MIB database?
The MIB database is a collection of MIBs bundled with the product. This database is useful to monitor any specific device on your network. The SNMP tools such as SNMP walker and the MIB browser would help in monitoring and collecting data about any device on your network using the MIB database.

6. What protocols are used to collect / retrieve data?
ManageEngine OpUtils uses SNMP, CLI, ICMP, ARP and reverse lookup protocols such as DNS.

7. I don't have SNMP installed in my machine. What should I do?
Refer to the Help documentation for Installing SNMP:
Help -> Getting Started -> Installing SNMP

8. I have some specific devices in my network such as Printer, etc. How do I monitor them?
You can monitor any device using SNMP tools from ManageEngine OpUtils. You can use the Custom Tools to create user-specific tools to monitor any specific SNMP - enabled device in your network.

1. Issue in starting OpUtils
Issue in starting OpUtils can occur for the following reasons:

(1) If the shutdown port is occupied during startup of OpUtils -> To resolve the issue, change the shutdown port with the unbinded port in the server.xml file located in

/AdventNet/ME/OpUtils/conf directory.

2. After logging into the OpUtils client, clicking any links or tabs from the welcome screen takes me back to the login page. Why?
The possible reasons could be:

1. The DNS name is not configured the DNS Server - Try giving the IP Address to connect to the client.
2. Misconfiguration in Browser settings - Try connecting to the client from a different browser/ machine.
3. Security configuration, if any security software is installed - check after stopping the security software.

3. Devices are not responding to ping.
This happens if:

(1) the device is not in the network
(2) ICMP request times out
(3) the packet size is too big

To resolve the ICMP Timeout, and the packet size issue, click the Settings tab. In the ICMP table,
1. Increase the Timeout value. The max value is 5000.
2. Reduce the packet size. The min value is 0.

Note: When a Linux device is pinged, the default number of packets sent are 8 ICMP packets+ the number of packets specified by the user in the ICMP table. Hence, even if the packet size is reduced to 0 by the user, ping by default will sends 8 ICMP packets to the device.

4. SNMP nodes are shown as non-SNMP nodes.
Check if the SNMP Agent is running in the device. If SNMP agent is not running in a device, the device will be discovered as non-SNMP node. Refer to Configuring SNMP Agents for details.

5. Devices are identified by incorrect IP addresses and host names
The possible reasons could be:

1. the DNS Server is not reachable.
2. the DNS Server is down.
3. the DNS Server does not exist.

Try the Ping Tool.

6. Performance Monitor tool does not show the list of correct Interfaces
This happens if the SNMP agent is not running in the device.

7.The Subnet List Tool does not display all the subnets in the network
Subnet List creates the list of subnets by scanning the route tables, hence if the subnets have been summarized into a summary route on the router you are scanning, the Subnet List will not be able to discover the subnets in the network.

8. Switch Port Mapper does not work
Only Switches that support the BRIDGE-MIB can be mapped, hence check if the Switch supports BRIDGE-MIB.

9. Switch Port Mapper displays only the MAC Address and not the IP Address.
The possible reasons could be:

1. The Router input is not specified. Enter the Router name to map the MAC Addresses to IP Addresses. The Router should be in the same subnet as that of the devices connected to the switch.
2. If the router input is not given, the information is obtained from the ARP cache of the switch. A cache file is also maintained locally to store this information. Perform a ping scan of the subnet to update the cache and then perform Switch Port mapping. This will improve the MAC to IP resolution.

10. Switch Port Mapper tool displays an error as "E2005: Not able to retrieve complete data from the MIB - BRIDGE MIB"
The possible reasons could be:

1. If virtual LAN is configured in the switch, the VLAN ID has to be supplied along with the community string. For example, if the VLAN ID is 2 and the community is "public", then the community string has to be specified as "public@2"
2. The switches has the ability to learn the source MAC Addresses from the traffic received on the ports. This feature can be turned on or off based on the implementation of the switch. If this feature is turned off, you will get this error.
