OpenManage Essentials Troubleshooting Tool

The OpenManage Essentials troubleshooting tool is a standalone tool that installs along with OpenManage Essentials.

You can use the troubleshooting tool for a wide array of protocol related problems that are often at the root of discovery

and alert issues.

This tool provides the following protocol-specific diagnostics to identify the problem with the remote node:

• Database—Fetches all the user defined databases present on the remote box.

• Dell|EMC—Verifies the connection to the Dell|EMC storage devices.

• ICMP—Verifies whether you can ping the remote device from the local box.

• IPMI—Verifies the IPMI protocol to connect to BMC/iDRAC.

• Name Resolution—Verifies whether you can get the resolved name from the local box.

• OpenManage Server Administrator Remote Enablement—This test helps you to verify that Dell OpenManage

Server Administrator's remote enablement feature is working on the managed node (Dell OpenManage Server

administrator installed with the remote enablement component). This tool behaves like a Server Administrator

Distributed Web server (DWS) and connects to Server Administrator managed node instrumentation agent using

the WSMAN protocol.

To connect successfully, the Managed Node must have OpenManage Server Administrator installed with the

Remote Enablement feature working.

• Port—Verifies whether managed node is listening to the specified port. You can specify 1-65,535 port numbers.

• PowerVault Modular Disk Arrays—Verifies that PowerVault modular disk storage array protocol is used to

connect to PowerVault Storage devices.

• Services—Uses SNMP protocol to fetch the running services on the managed node.

• SNMP—Verifies SNMP connection to the remote node, using the required SNMP community string, retries, and

time out. First it tries to connect to MIB-II agent and then various other agents to find out the type of device.

Troubleshooting Tool also gathers other agent specific information from that device.

• SSH—Verifies that the SSH protocol is used to connect to managed node.

• WMI—Verifies WMI/CIM connection to the remote node. Default retries and time out values are used internally.

• WSMAN—Attempts to connect to WSMAN client on the remote node. Use this test to verify connectivity

problems with iDRAC, ESX, and other devices, which support WSMAN specification. This test will connect to

such devices and will also list the exposed WSMAN profiles enabled on the remote device.
