If the list of IP ranges being scanned is very large, you can configure the Shazzam payload for JSON encoding to reduce its size. Before you beginRole required: admin About this taskYou control the behavior of individual Shazzam probes using basic and advanced parameters.For instructions on configuring probe parameters, see Set probe parameters. Procedure Navigate to Discovery Definition > Probes. Select Shazzam. Add or edit parameters in the Probe Parameters related list. Configure the basic Shazzam parameter. 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. Table 1. Basic Shazzam parameters Parameter Description shazzam_chunk_size Maximum number of IP addresses Shazzam will scan in parallel. This parameter primarily controls outbound port consumption.Default: 100 regulator_max_packets Sets the number of packets that Shazzam can launch in the time interval specified by the regulator_period_ms parameter. Default: 1 regulator_period_ms Sets the interval, in milliseconds, in which Shazzam can launch packets.Default: 1 Configure the advanced Shazzam parameters. These parameters are available for fine tuning the Shazzam probe. These values are defined in the probe record only. Table 2. Shazzam advanced parameters Parameter Description BannerTCP_waitForConnectMS Sets the number of milliseconds the BannerTCP scanner waits for a connection and banner.Default: 1500 debug Enables debug logging if set to true.Default: false delay_webem Delays classification of systems with a WBEM port open until the final Shazzam sensor job. In the case of a large schedule discovering many WBEM ports, delaying classification until the last sensor job could cause the node to run out of memory. Setting this parameter to false allows classification of these systems to occur across all Shazzam sensor jobs.Default: true DNS_alternativePort Deprecated DNS_waitForResponseMS Sets the number of milliseconds the DNS scanner waits for a response.Default: 1000 GenericTCP_waitForConnectMS Sets the number of milliseconds the GenericTCP scanner waits for a connection.Default: 1000 HTTP_waitForConnectMS Sets the number of milliseconds the HTTP scanner waits for a connection.Default: 500 HTTP_waitForResponseMS Sets the number of milliseconds the HTTP scanner waits for a response.Default: 500 NBT_alternativePort Deprecated NBT_waitForResponseMS Sets the number of milliseconds the NBT scanner waits for a response.Default: 500 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.Default: true scanner_log Enables scanner logging if set to true. This logging information appears in the Shazzam probe response.Default: false shazzam_report_dead When true, reports devices with dead IP addresses. For example, a device that has all ports closed.Default: false SNMP_alternativePort Deprecated SNMP_tapIntervalMS Sets the number of milliseconds the SNMP scanner waits between taps.Default: 1000 SNMP_taps Sets the number of taps (requests) the SNMP scanner attempts.Default: 2 SNMP_waitForResponseMS Sets the number of milliseconds the SNMP scanner waits for a response after the last tap.Default: 1000 Control Shazzam payload size A system property converts Shazzam payloads into JSON strings, which dramatically reduces their size. This setting prevents nodes from running out of memory when a single schedule discovers large numbers of IP ranges. Before you beginRole required: admin About this taskThe glide.discovery.shazzam_ranges_json property is set to true for new instances. This setting encodes the payload as a JSON string. The property is configurable by administrators and is available in the Discovery Definition > Properties module. The property label is Use JSON for IP ranges in Shazzam in the module.This property is set to false in upgraded instances and is not visible by default. Adding the property manually to your upgraded instance enables the feature, but does not add it to the Discovery Definition > Properties module. To enable JSON encoding and add it to the module, import the update set attached to KB0687626. Procedure In the navigation filter, type sys_properties.list and press Enter.
