SolarWinds Server Health Monitor Quick Reference Guide

The SolarWinds® Server Health Monitor (SHM) is a free diagnostic tool that provides basic-level health status server monitoring for up to five servers in a corporate enterprise. You can download it from SolarWinds pages here.

Using Simple Network Management Protocol (SNMP), Windows Management Instrumentation (WMI), and Common Information Model (CIM) calls to your network frameworks and application servers, the tool polls the basic system components in each configured server (such as the power supply, temperature, and fan) and displays a server health overview of all monitored servers in the Dashboard tab. The tool is supported on selected VMware® hypervisors and Dell™, HP®, and IBM® servers.

If you need expert-level health status server monitoring for over 200 applications and 1000 servers in a corporate enterprise, see the SolarWinds Server and Application Monitor.

Hardware monitoring agent software

Each computer hardware vendor installs hardware monitoring agent software on their systems, which includes a Web server that operates on a unique port.

Remote servers include the hardware monitoring agent software for both SNMP and WMI.

Note: The blade enclosures do not use hardware monitoring agent software.

To ensure that the hardware monitoring agent software is installed on your system, open a Web browser and navigate to the following URL:

https://<remote_ip_address>:Port

where remote_ip_address is the remote server IP address and Port is one of the following ports:

 

HP: 2381

Dell: 1311

IBM: 423

  • You can poll the following servers using WMI:
    • Dell PowerEdge M1000e Blade Enclosure
    • HP BladeSystem c3000 and c7000 Enclosures
    • HP ProLiant servers
    • IBM eServer xSeries
  • You can poll the following hypervisors with no required polling setup:
    • VMware vSphere ESX
    • VMware vSphere ESXi
    • These hypervisors use the CIM protocol that should be enabled by default after you install the ESX or ESXi hosts.

Configure polling using SNMPv2

 

  1. Ensure that SNMP is enabled on the monitored server. See your server or VMware documentation for information about configuring SNMP.
  2. Click the drop-down menu and select SNMPv2.
  3. In the Community String field, enter your SNMP credentials.
  4. Click . The monitored server connection is configured, and the tool automatically polls the server for server health data. The polling process may require several minutes to gather the server data.

Configure polling using SNMPv3

 

  1. Ensure that SNMP is enabled on the monitored server. See your server or VMware documentation for information about configuring SNMP.
  2. Click the drop-down menu and select SNMPv3. The Server and Credentials box appears.
  3. In the Username field, enter the IP address or user name of the server you want to monitor.
  4. In the Context field, enter your SNMP credentials.
  5. In the first drop-down menu, select an encryption algorithm for the polling connection. MD5 (Message Digest) provides a 128-bit hash algorithm. SHA1 (Secure Hash Algorithm) provides a 160-bit hash algorithm.
  6. Click the second drop-down menu and select an encryption cipher for the polling connection.
  7. In the Password field, enter an authentication password.
  8. Select the Password is a key check box to select the algorithm of the encryption. Note: If you select this check box, leave the Context field blank.
  9. Click . The monitored server connection is configured, and the tool automatically polls the server for server health data. The polling process requires one to two minutes.

Configure polling using WMI

 

  1. Ensure that WMI is enabled on the monitored server. See your server or VMware documentation for information about configuring WMI.
  2. Click the drop-down menu and select WMI. The Servers and Credentials box appears.
  3. In the Username and Password fields, enter your WMI user name and password.
  4. Click . The monitored server connection is configured.

 

 

View your server health

When you click the Dashboard tab, the tool polls the monitored servers and displays a health status overview of all servers. The overview includes a pie chart, node count, and summary information of all monitored servers.

The polling process requires up to two minutes to complete, depending on your network configuration. During the polling process, Processing appears at the bottom of the window.

The Node Count lists the number of monitored nodes and the corresponding status. The Summary lists all monitored servers and their corresponding status.

The following table provides descriptions of each status.
