AutoDiscovery module parameters

Allows you to access the list of autodiscovered devices and the Autodiscovery module configuration.

Parameter

Default Value

Description

Maximum Device Age (sec)

3600

The maximum age in seconds for an entry in the device list. This is the maximum time a device can stay in the list of devices after last being verified.

Timeout (sec)

5

Defines the timeout value in seconds for pings sent to check for other machines in the neighbourhood.

Address Range

The list of addresses to be verified. The IP addresses can be listed in the following different notations:

  • Dotted notation, for example, 94.24.127.24
  • With the short or complete network name such as scotty or scotty.enterprise.com
  • A mixture of both: 94.24.127.24, scotty.enterprise.com .If the complete IP address range declaration is incorrect, the current subnet is scanned by default from address x.x.x.1 to x.x.x.254. If no IP address range is specified, the current subnet is scanned by default from address x.x.x.1 to x.x.x.254.

HTTP Port Range

80,1610,8080

The range of ports to scan for an agent HTTP server. All specified port ranges is scanned for ALL listed IP address ranges! If no port range is specified only default ports 1610 and 8080 is scanned.

Address Verification Interval (sec)

30

The gap in seconds between each address verification.

Number of Neighbors

10

Defines how many neighboring addresses to scan. The default value is 10, meaning 5 addresses below the device's own address and 5 addresses above it.

TCP Port Range

23,25,139

The range of ports to scan for a TCP connection. This is used in place of ping when raw sockets are not available. All specified port ranges is scanned for ALL listed IP address ranges! If no port range is specified only default ports 23, 25 and 139 is scanned. Each port range can consist of:

  • only one port number
  • one port range with the start and end port numbers separated by a dash (minus),
  • several port ranges and/or individual port, for example: 10000-10100,20000,21000-22000
  • Several port ranges must be separated by either a space, a comma (,), a semicolon (;) or a colon (;). If the whole range declaration is incorrect only default port 10000 is scanned.

Use Network Neighborhood

Yes

Defines whether the network neighbourhood should be used to get machine names and addresses.

Same Network Only

3

Specifies if devices found on other networks are to be accepted. The possible values are the following:

  • No filter applied : There is no filter applied to any of the discovered devices.
  • Clients only : All discovered client devices must be on the same network as the discovering device.
  • Relays only : All discovered devices, which have their relay function enabled, must be on the same network.
  • All devices : All discovered devices must be on the same network.

Scan Count

30

Each time Scan Count addresses have been verified, the module refreshes the list of addresses to verify by using the Address Range, Number of Neighbors and Use Network Neighborhood settings.

Can Learn

Yes

Specifies that the agent can get other agents' autodiscovered devices in order to establish its list.

Maximum Hop Count

2

The maximum number of routers which may exist between the device providing the list and the device being read. The hop count is determined at discovery time using the ping. It provides an indication of the distance between the two devices and is used at the time of relay selection to sort the devices which are farther to the end of the list of relays being contacted.

Upload on Startup

No

Defines if the inventory is uploaded to the master after being updated the first time on agent startup. It is recommended to activate this option to ensure that the inventory is updated at least at every startup of the agent. If it is deactivated a regular update and upload of the inventory must be configured through operational rules.

Upload Interval (sec)

3600

Defines the upload period for the inventory in seconds. If it is set to 0, no uploads are configured by the module, but they can still be managed through operational rules. The setting only configures the upload of existing data, it does not include an update of the inventory.

Fast Address Verification Interval (sec)

10

Defines a fast search option to find the client's relay. If the list of devices is empty, the Fast Address Verification Interval value is used to verify devices until the Scan Count value is reached and all devices have been verified or a relay was found. If the client has a relay the Address Verification Interval value is used. If the IP address is modified, the Fast Address Verification Interval value is used to verify devices. The option is deactivated if the value is set to the same value as the Address Verification Interval value. As long as the AutoDiscovery is at the research for the device's relay, the Parent Selection Retry Interval to find the backup server is ignored.

Operating System Detection

Yes

Specifies that the operating system is discovered on the device found by autodiscovery.

Upload AutoDiscovery Module Objects

Yes

Defines if the objects discovered by the autodiscovery are uploaded,.

Operating System Detection

Yes

Specifies that the operating system is discovered on the device found by autodiscovery.
