System settings for the NNS service are behind button Nilex Network Scanning Service settings in the panel menu.
NNS Tab General

Command timeout decides the period of time NNS service will wait for agent response. High Command timeout is needed for search in the large database tables, e.g. application usage table Autorestart on DB error should be enabled since if database connection is broken, NNS Service will shut down. Thus it will automatically try to restore itself when database connection can be established.
|
Enable automatic disposing means that it is possible to set that if a network unit has been unavailable for a number of days, it will be automatically moved to a separate list of disposed units. If the computer once more becomes active after being set disposed it will move back to the main list. Disposed units are not imported into the NSP Inventory database.
Log Enabled activates log for the service. Log file NilexNetworkScanningServiceApp.exe.log is in folder C:\Documents and Settings\All Users\Application Data\Nilex Network Scanning\Network Map Server.
NNS Tab Discovery Options

Figure 13-Discovery Options |
•Read-only Community determines how to look up SNMP information from custom network units. The standardized default string identifier is “public”. •SNMP Timeout is the amount of seconds before a unanswered SNMP call is interrupted. •SNMP Retries is the amount of tries •Ping Timeout is seconds to wait for a ping answer. •Enable custom units availability check decides whether NNS Service should check if custom units are online (non-computers). |
•Edit Custom SNMP Unit Types opens a dialog for administration of SNMP units.
NNS Tab Inventory Collection
|
Figure 9-Inventory Collection |
•Automatically upgrade agents – allow agents to be upgraded automatically as soon as they get online •Store history [ ] months set how long history data will be stored. This setting applies for Application Usage – history of programs started and User Logons – history of logged on users on the computer. |
Note that application usage tables can be large depending on for how many months data is stored and how many units there are in your network. A large application usage table can slow down the SQL server. If this is so it is recommended to keep down the amount of data with Exclude rules. For example you can decide which application usage you want to monitor and save only data for these.
•Setup registry inventory – settings for collect from register.
•Setup license inventory – settings for collect of license keys from the register.
Tab Collection Mask
|
Figure 14 – Collection mask |
Here is yet another way to limit the collecting data. The difference in limiting the collection between collection mask from filtering is that in Collection Mask you state what to be collected by the agent, whereas in filtering you state what not to be saved. A technical description of what client information is gathered by the agent is listed in Appendix: NNS Collection mask properties. Collect of executable files makes collect time 30-60 seconds longer |
