- Collect performance and environmental data Enable or disable device performance and environmental information for all member devices in the group. For more information, see Changing Performance Data Collection Settings.
- CLI polling in privileged mode: Enable or disable CLI polling in privileged exec mode for the device group. You can override this setting for individual devices in the Device Viewer.
- Probe for open ports: If enabled, TCP and UDP ports listed at Settings icon > Setup section > Port List are probed to determine whether they are open.
- Analyze device using fingerprinting: If enabled, fingerprinting attempts to identify each device based on the response characteristics of the TCP stack being used.
- Probe for NetBIOS name: Setting to enable NetMRI to collect the NetBIOS names for endpoint device members in the device group. For more information, see Defining Group Data Collection Settings. It is globally disabled by default to prevent unexpected scanning of the network by a new Operations Center Collector.
- Analyze for Issues: NetMRI evaluates over 250 discrete Issues, plus custom Issues defined by the admin user. Issues are discovered and reported by NetMRI based on globally set schedules. Disabling this feature for a device group disallows the group from being selectable in the Device Group Selector panel in the main Network Analysis –> Issues page. For more information, see Evaluating Issues in NetMRI, and Viewing Device Issues, Configurations and Changes.
- Test for default credentials: Allows NetMRI to test all devices in the group for the presence of vendor default SNMP credentials, which are a potential element for security breaches, but are also used for assistance in collecting device configurations. Credential default testing is also a compliance measure.
- Collect config files: When enabled, this checkbox allows NetMRI to collect all present configuration files for devices in the device group. To participate in the Configuration Management feature set, which allows you to view and compare differences between running-config and saved-config configuration files, edit, and manage config files on devices. For more information, see Configuration Management.
- Regard configurations as 'Locked': Disallows editing of any collection configuration files for members of the device group.
- Allow script execution: Allows the execution of Perl and CCS scripts on member devices.
- Refresh device caches before collecting switch port data: Checkbox to enable refreshing of ARP caches on switches and switch-routers in the managed network before NetMRI performs polling of switch ports.
Enabling this feature will not produce an automatic ping sweep of the managed network. For more information on ping sweep, see Defining Group Data Collection Settings. The benefit of this feature is that it enables more accurate detection of all endpoint devices on switches. Without ARP refresh, some endpoint devices may not be detected. This feature is globally disabled by default. With this setting globally enabled, individual device groups can also be set to enable or disable this feature.
For more detailed descriptions of these options, see Global > Network Polling and Config Management.
