Debugging Issues in Discovery and Data Collection

Note

The Juniper devise discovery polling intervals occur hourly because such devices do not support the ccmHistory SNMP MIB object, which is limited to Cisco devices.

The CC column in the Network Explorer > Discovery table reveals important debugging information for configuration collection issues. The most important discovery and Config Collection issues are listed in this topic, along with where in NetMRI to fix them.

Config Collection	Warning icons in the CC column indicate possible configuration data collection problems. Other locations that report related messages include Device Viewer > Settings & Status > Management Status and Settings icon > Setup > Discovery Settings > Seed Router. Specific messages are described below.
Config Not Changed	The configuration for the device has not changed since the previous polling of the device. No problem is indicated here unless you have pushed a changed configuration to the device. Even in those cases, allow some more time for the device to synchronize with NetMRI. If you expect changes to be reflected in device polling. go to Device Viewer > Configuration Management > Config Explorer and check the Running Config Saved? status line. If the answer is No, ensure the changes in the device's running-config are saved according to the device's configuration data saving requirements.
CLI Credentials Unknown	NetMRI cannot obtain the device configuration due to not having the correct CLI username/password tuple, and credential guessing did not work for the device. Go to the Device Viewer > Settings & Status > CLI Credentials page for that device. Click Edit and enter the necessary values for the SSH and/or Telnet login tuple and the Enable Password if necessary. Each attempt at connection and collection is listed in the table. Note that the C column, for CLI Credentials Status, may show an Error, usually listed as Failed to authenticate: Invalid Username and/or password.
Configuration Collection Disabled Globally	This message appears for devices that support configuration collection, but the collection was skipped because Config Collection is globally disabled in NetMRI. The same message appears in the Device Viewer > Settings & Status > Management Status page. Go to the Settings icon > Setup > Collection and Groups > Groups > Config Management side tab, and enable the Config Collection checkbox. Also, ensure the proper protocols (SSH, Telnet, HTTP) are enabled for config collection.
Configuration Collection Enabled Globally, All Protocol Options Disabled	This message appears for devices that support configuration collection, but the collection was skipped because Config Collection is globally enabled in NetMRI but no data collection protocols were enabled. The same message appears in the Device Viewer > Settings & Status > Management Status page. Go to the Settings icon > Setup > Collection and Groups > Groups > Config Management side tab, and enable the Config Collection checkbox. Ensure the proper protocols (SSH, Telnet, and/or HTTP) are enabled for config collection.
Configuration Collection Disabled at Device Group level	The device showing this message currently has config collection disabled for the Device Group to which the device belongs. Go to the Settings icon > Setup > Collection and Groups > Groups, click the Action icon, and choose Edit for the selected Device Group. In the Group Settings tab, enable the Config Collection checkbox.
Not Included by Discovery Settings	The message indicates that although the device has been detected by NetMRI, it is not included in any IP Ranges or as a Static IP with the Exclude from Discovery Settings option, is not reachable through Device Hints, or is not detectable as a Seed Router. The device in question may also be explicitly excluded from management by previously clicking the Unmanage button in Device Viewer > Settings & Status > Management Status page. Go to Settings icon > Setup > Discovery Settings and change the appropriate settings in any of the four categories. This message appears only during a manual Get Config operation.
Not LIcensed	The message indicates that the device has not been added automatically to the full NetMRI license for the appliance reporting the Issue. Go to the Device Viewer > Settings & Status > Management Status page and click the License button. In the License Status dialog, choose the settings necessary to change the licensing status for the device. This message appears only during a manual Get Config operation.
