Here's an explanation of settings in the Common tab.

SettingDescription
Number of threads

Set the number of parallel running scan threads. (default are 4)

Recommended (and maximum) are 2 thread per core (e.g. if you are using a 8 Core CPU best performance are by 16 threads)

Instance prefixA user defined string that allows to identify different Discovery-Instance after import the Discovery-Settings to Insight
Max scan thread time (m)After configured minutes a scan thread will be canceled.
Log level

With the "Normal"-Setting the Log file will only contain basic information's like the ICMP-Result and the Discovery Statistic.

With the "Debug"-Setting the Log file will contain much Information that can help for support you by a problem.

Split log per thread

If this option is set, the Discovery-Tool will create multiple log files and create a subfolder for each scan.

Each logical thread will result in a log file. The filename will end with the internal number of thread.

The main thread will always be the file ending with 0000 and contains information of started threads

and can be used as index for searching a specific scan file.

Delete logs after (days)

LogFiles (and folders) will be deleted after the configured time.

(default = 7 days)

Delete unknown hosts*

If this option is set, the Discovery-Tool will remove all "Unknown Hosts" from the result.

"Unknown Hosts" are hosts that responding to ICMP Requests, but the credentials to get full details are missing

and we can't get basic informations (see "Basic Hosts")

ICMP timeout

Configures the timeout for ICMP (Ping) requests in milliseconds.

(default = 300 milliseconds)

ICMP repeats

Configures the amount of retries of ICMP Requests (when the request was not successful)

(default: 0)

Delete basic hosts

If this option is set, the Discovery-Tool will remove all "Basic Hosts" from the result.

"Basic Hosts" are hosts that responding to ICMP Requests, but the credentials to get full details are missing.

The Discovery-Tool can only try to get a hostname via DNS-Reverse-LookUp and optional a MAC-Address via arp-cache.

SNMP timeout (ms)

Configures the timeout for SNMP connections in milliseconds.

(default = 500 milliseconds)

Delete VM guests

If this option is set, the Discovery-Tool will remove all "Virtual Guests" that are found by some pattern from the result.

This will prevent creating "double" Hosts if you also full discovering the VM Guest with WMI or SSH credentials.

SSH timeout (s)

Configures the timeout for SSH connections in seconds.

(default = 40 seconds)

Delete duplicate device

If this option is set, the Discovery-Tool will remove a Device (SNMP) and keep "duplicate" Host Object.

If the option is not set and a Host also responding over the SNMP Interface the result data will contain a Host and a Device Object for that system.

WMI timeout (s)

Configures the timeout for WMI connections in seconds.

(default = 25 seconds)

User PowerShell

If that option is checked, the Discovery-Tool try to establish a PowerShell connection to the remote server.

If that was successful the alternative PowerShell-Pattern will be used instead of the WMI-Pattern.

Also it is possible to use Custom PowerShell-Pattern.

vSphere timeout (s)

Configures the timeout for vSphere connections in seconds.

(default = 25 seconds)

Auto add sudo

If this option is checked "sudo" will be added to all SSH-Commands

Please just enable PowerShell if:

  • The Discovery-Tool is used in a Domain Environment
    (PowerShell just work in a Domain!)
  • A DNS Server is reachable
    (PowerShell needs a FullQualifiedDomain-Name for the remote machine, so for each IP address the Discovery-Tool perform a DNS-Reverse Lookup)

If the the described points not available the performance of the Discovery-Tool will drop dramatically!

Try VM guest scanIf that option is checked, the Discovery-Tool will try a "full"-scan of the found VM-Guests if they had available NetworkInterface Informations and working credentials for that system/ip
Change password

Here you can change your settings password.

*Only available by using the Discovery Tool on a Windows Environment.
