Shazzam probe parameters

You can control the behavior of individual Shazzam probes using basic and advanced parameters.

For instructions on configuring probe parameters, see Set probe parameters.

Basic Shazzam parameters

These parameters are defined in the config.xml file on the MID Server, but you can edit the values in the Shazzam probe record as well. Changes to specific parameters that could disconnect you from the MID Server are prohibited in the probe record and can only be made in the configuration file.

Property Description Default
shazzam_chunk_size The maximum number of IP addresses Shazzam will scan in parallel. This parameter primarily controls outbound port consumption. 100
regulator_max_packets Sets the number of packets that Shazzam can launch in the time interval specified by the regulator_period_ms parameter. 1
regulator_period_ms Sets the interval, in milliseconds, in which Shazzam can launch packets. 1

Advanced Shazzam parameters

These parameters are available for fine tuning the Shazzam probe. These values are defined in the probe record only.

Property Description Default
report_inactive When true, reports device that are alive but inactive. For example, a device has no ports open but refuses at least one port connection request. true
shazzam_report_dead When true, reports devices with dead IP addresses. For example, a device that has all ports closed. false
GenericTCP_waitForConnectMS Sets the number of milliseconds the GenericTCP scanner waits for a connection. 1000
BannerTCP_waitForConnectMS Sets the number of milliseconds the BannerTCP scanner waits for a connection and banner. 1500
HTTP_waitForConnectMS Sets the number of milliseconds the HTTP scanner waits for a connection. 500
HTTP_waitForResponseMS Sets the number of milliseconds the HTTP scanner waits for a response. 500
NBT_waitForResponseMS Sets the number of milliseconds the NBT scanner waits for a response. 500
NBT_alternativePort Defines an alternative port number for the NBT scanner. N/A
SNMP_taps Sets the number of taps (requests) the SNMP scanner attempts. 2
SNMP_tapIntervalMS Sets the number of milliseconds the SNMP scanner waits between taps. 1000
SNMP_waitForResponseMS Sets the number of milliseconds the SNMP scanner waits for a response after the last tap. 1000
SNMP_alternativePort Defines the alternative port number for the SNMP scanner. N/A
DNS_waitForResponseMS Sets the number of milliseconds the DNS scanner waits for a response. 1000
DNS_alternativePort Sets an alternative port number for the DNS scanner. N/A
debug Enables debug logging if set to true. false
scanner_log Enables scanner logging if set to true. This logging information appears in the Shazzam probe response. false
