The Properties window contains several views, displaying different categories of parameters (e.g., General, Settings, System, …). Users can switch between views, by selecting the corresponding entries from the category drop-down list displayed in the upper section of the Properties window. Note that some of the entries displayed in the category drop-down list are static (i.e., always displayed), while others are dynamic, i.e., they are displayed only if the managed object provides information from the respective category and only if Net Inspector Server is used for polling these managed objects.
Note If polling is performed by a Performance Manager polling engine (e.g., when using MG-SOFT Net Inspector WorkGroup or Enterprise Edition), the dynamic entries are not displayed in the managed object’s Properties window. Instead, the corresponding interface, services and device resource usage statistics are displayed in the Performance Statistics window.
The following entries (and views) in the Properties window are static:
General (object name, address, description, list of active alarms, etc.)
System (object type, class, location, vendor, OS, etc.)
Settings (assigned polling and SNMP profiles, resynchronization configuration)
Services (monitored TCP and UDP services) – in Net Inspector LITE Edition only If the managed object supports SNMP protocol, the following dynamic entries may appear in the category drop-down list of the Properties window (depending on the MIB modules supported by the SNMP agent on the given device and the polling profile and polling engine assigned to the corresponding managed object):
Interfaces (information about system network interfaces)
Resources (information about the system resources)
Storage (information about the system storage units)
The Properties window status bar displays the following object properties (from left to right):
The icon and name of the object,
The node ID, i.e., the identification number of the device that has been assigned to it by the user (according to the user’s classification system)
The ID of the object, i.e., the unique identification code of the object within the Net Inspector system,
The current status of the managed object.
9.2.1 General View
The General view of the Properties window provides the following information (Figure 65):
Name (input line)
Displays and lets you edit the name of the managed object. By default, this is the host name of the managed object.
90 Type (input line)
Displays the type of the managed object (e.g., IP).
Address (input line)
Displays and lets you edit the IP address or the host name of the managed object.
Description (input line)
Displays and lets you edit a short description of the managed object. Net Inspector discovery operation enters the value of the sysDescr.0 object instance returned by the SNMP agent into this input line.
Polling Engine (drop-down list)
Displays and lets you lets you select the polling engine used for polling the given device.
This is useful when MG-SOFT Performance Manager application is installed and integrated with MG-SOFT Net Inspector application (multiple polling engines can be deployed across the network in such configuration). If you select a Performance Manager polling engine in this drop-down list, additional performance statistics about the given device will be available via the Show Performance Statistics command. If the option Built-in engine is selected, then the given device is polled by Net Inspector Server and no performance history data is available for it.
Note: This drop-down list is enabled only when using Net Inspector Workgroup or Enterprise Edition, which include the Performance Management functionalities.
NetFlow source (checkbox)
Sets the selected managed object as a NetFlow source device, i.e., a device that sends NetFlow v5 or v9 packets or sFlow v5 packets to Net Inspector (this must be first configured on the given device (e.g., a router) using vendor-specific methods). Net Inspector WorkGroup and Enterprise Editions incorporate a NetFlow collector and analyzer software module that receives NetFlow packets from source devices and provide NetFlow traffic statistics in the Polling Engine Home Page window, NetFlow page.
Active alarms (frame)
Displays the object alarm summary (the total number of active alarms and number of active alarms broken down by severity levels) and a list of active alarms on the given object (same as in the Events window).
9.2.2 System View
To switch to the System view, select the System entry from the category drop-down list (Figure 65). The System view provides the following information (Figure 66):
Type (input line)
Displays the type of the managed object (IP).
Class (input line)
Displays the class of the managed object.
Tags (input line) and Edit (button)
Displays and lets you add a tag (user description) to the managed object. Objects can be searched by the value of their tags.
91 Location (input line)
The physical location of the managed object. Net Inspector discovery operation sets this value to the value of the sysLocation.0 object instance returned by the SNMP agent.
Vendor (input line)
The vendor of the managed object. Net Inspector discovery operation sets this value to the name of the enterprise responsible for the OID returned by the sysObjectID.0 object instance. The enterprise names displayed are taken from the list of private numbers as registered with IANA and stored on the Net Inspector Server (//Engine/data/nienterprise.txt).
Figure 66: Properties window – System view OS (input line)
The operating system running on the managed object.
URL (input line) and Open (button)
The URL (uniform resource locator) address, e.g., which provides additional information about the managed object (e.g., http://www.iskratel.si/).
Icon (input line)
The name of the icon used for representing the managed object (as configured in the Manage Object Typed window).
Geographic coordinates (frame)
The geographic coordinates that specify the physical location of the managed object.
The geographic coordinates are compatible with the GoogleTM Maps coordinates.
92 X (input line)
Specifies the geographic coordinate projected on the X-axis.
Y (input line)
Specifies the geographic coordinate projected on the Y-axis.
Z (input line)
Specifies the geographic coordinate projected on the Z-axis.
9.2.3 Settings View
To switch to the Settings view, select the Settings entry from the category drop-down list (Figure 65). The Settings view provides the following information (Figure 67):
Polling profile
This drop-down list displays the name of polling profile assigned to the managed object. A polling profile contains a set of parameters for polling managed objects via ICMP and SNMP protocols. Users with administrator access rights can assign a different polling profile to the managed object by selecting its name from this drop-down list.
SNMP access profile
This drop-down list displays the name of the SNMP access profile assigned to the managed object. An SNMP access profile contains a set of parameters for accessing SNMP agents on managed objects. Users with administrator access rights can assign a different SNMP access profile to the managed object by selecting its name from this drop-down list
Figure 67: Properties window – Settings view
Resynchronization (frame)
The Resynchronization frame is available only if the managed object is of type “IP”.
The settings in this frame control how the event resynchronization is performed (Command) with the given object and how Net Inspector monitors whether the events are synchronized or not for the given object (e.g., third-party device). These settings
93 are used for synchronizing the events with arbitrary third-party SNMP agents that support event resynchronization.
Command (input line)
Specifies the command that triggers the resynchronization of events with a third-party SNMP agent.
Enterprise OID (input line)
Specifies the enterprise OID associated with the SNMP notification (i.e., the value of the Enterprise field in SNMPv1 Trap messages or the value of the snmpTrapEnterprise.0 variable binding in SNMPv2 and SNMPv3 Trap and Inform messages). Each SNMP notification message that reports an event on the managed object must contain the specified enterprise OID in order for it to be accepted by Net Inspector as event.
Trap count binding (input line)
Specifies which variable binding in the variable bindings list (e.g., binding nr. 3 or 4 or 5…) of the SNMP notification message reports the current event count (i.e., the number of events on the given managed object). Net Inspector Server checks the continuity of this counter in every received SNMP notification message reporting events to determine if its list of events is synchronized with the list of events maintained internally by the managed object. If a difference in the trap count value is detected, Net Inspector executes the above configured resynchronization command.
9.2.4 Services View
The Services view is displayed only in the LITE Edition of Net Inspector. In other editions of Net Inspector, the services statistics are displayed in the Performance Statistics window.
The Services view allows users with administrator access rights to scan the well-known ports on the device for supported TCP and UDP network services. These services include HTTP, HTTPS, FTP, DNS, SMTP, IMAP, IMAPS, POP3, SSH, Telnet, NNTP, NNTPS, SIP, H.323, LDAP, LDAPS, IPP, LPD, MsSQL, MySQL and Oracle services. Users with administrator access rights can also select which of the detected network services will be monitored on the given device, as well as configure and enable monitoring of custom, user-defined services. Once configured, the Services view displays the status of monitored services (i.e., whether the services are accessible or not).
To switch to the Services view, select the Services entry from the category drop-down list (Figure 65). The Services view provides the following information (Figure 68):
The Services view displays the Services list providing information about network services on the managed object in the following columns (note that this list is empty by default):
Note: Services will be monitored only if services monitoring is enabled in the polling profile assigned to the given managed object. How frequently the information displayed in this view is updated depends on the polling interval (Poll every X seconds) set in the polling profile.
