Host Discovery and Collection Configuration Steps Version 10.3.00P13

• Host Discovery and Collection Setup Overview - Collector pre-requisite, Manage Credentials, Manage WMI Proxy, Manage Paths, Manage Access Control, Discover Hosts

Read this section first for a high-level overview, then follow the specific steps in Before Discovering Hosts and Host Management to configure your system for Host Data Collection.

Because each enterprise has a unique inventory of hosts with specific access requirements and restrictions, the process of ensuring successful host data collection requires an assessment of the hosts in your environment (see ) and several configuration steps, as summarized below.

Note that some steps typically are required only as part of the initial configuration and rarely require additional maintenance. For the purpose of this document, these initial steps are treated as requirements Before Discovering Hosts.

Note: Each step is summarized in this section. To access detailed descriptions, click the links for each step. The buttons at the bottom of the window—Hide, Remove, Show Errors, Validate, Edit Probes, Copy Probes, Paste Probes—are described in the section, Host Discovery and Collection Maintenance Overview.

1. Prior to discovering hosts, a data collector policy must be configured. You can use an existing policy—for example, a data collector policy that has been created for Storage Array data collection—or create a new data collector policy.

2. Configure/Search - Using the Host Discovery and Collection window, you can search for hosts in the inventory; or you can set up configurations in preparation for discovering and configuring hosts.

• Configure and Edit Host Probes - Many of the probes may not be applicable to your enterprise. It is essential that you identify the probes that are relevant to your hosts.

3. Manage Credentials - Configure user IDs and passwords for authentication when the data collector is accessing hosts.

4. Manage WMI Proxy - A WMI Proxy is required to collect data from Windows hosts. Use this option to define one or more WMI Proxies.

5. Manage Paths - Configure the paths that data collectors will use to execute commands on hosts.

6. Manage Access Control - Data Collectors require read-only access to execute non-intrusive commands on hosts. It is strongly recommended that a separate login account, used strictly for APTARE IT Analytics, be established and using Active Directory for Windows systems and the sudo command for Linux systems, restrict the commands that APTARE IT Analytics can issue. To accommodate this security approach, you can optionally specify access control commands like sudo, sesudo, or pbrun. Files containing sudo commands per operating system can be found on the Portal server in: /opt/aptare/updates. These filenames contain both the OS and the version of the sudo commands file so that you can identify the files that contain the latest updates; for example: hpux_9.1.01, aix_9.1.01, linux_9.1.01, solaris_9.1.01.

7. Configure Host Discovery Policies to Populate the Host Discovery and Collection View - Host Discovery attempts to find hosts and populate your host inventory. Create Host Discovery Policies that use the credentials, WMI proxies, and paths that you configured.

• Validate Host Connectivity - Host validation must take into account host access for a wide variety of conditions and environments. As the discovery process accesses hosts, informative messages will provide clues to connectivity issues. In addition, devices that don’t belong in a host inventory—for example, printers in the IP address range that you specified—may have been discovered and need to be hidden or removed from the inventory.

1. Hide/Unhide Hosts - Host Discovery may find devices that are not hosts that you want to manage; for example, printers. For details, see Filter the Host Discovery and Collection window - Hide/Unhide, Remove.

2. Remove Hosts - Some IP addresses may be associated with devices that simply should be removed from the inventory, although if you execute a host discovery policy, the devices will return. For details, see Filter the Host Discovery and Collection window - Hide/Unhide, Remove.
