Overview

Discovery refers to the process Statseeker uses to locate devices on your network, and depending on the type of Discovery being run:

  • Test communications between Statseeker and the device for future data collection
  • Collect configuration information from those devices, building an inventory of monitored hardware

A Rewalk is a type of Discovery, but unlike a typical Discovery, a Rewalk does not discover any new devices. Rather, the Rewalk identifies configuration changes on known devices (those that have been previously discovered), updating the Statseeker configuration to match.

Statseeker has a default scheduled Rewalk which is scheduled to run Daily at 11am server-time.

  • The default Rewalk schedule can be modified
  • Additional Discovery processes can be scheduled
  • A scheduled Discovery can be configured with the same degree of customization as a manually run Discovery.

Scheduling Discovery

Multiple schedules can be configured, but do consider the start-time and typical duration of other scheduled Discoveries, as only a single Discovery process can run at a time. The Discovery process will first check to see if another Discovery is already running; if it is, then the new Discovery will not proceed.

To schedule a Discovery:

  • Select Admin Tool > Network Discovery > Discover My Network

Accessing the schedule configuration screen varies depending on the type of Discovery and whether or not the Discovery process is being customized.

Default Network Discovery or Rewalk

To schedule a default Network Discovery or Rewalk targeting all enabled IP Address Ranges, referencing all SNMP Credentials, and obeying all default settings:

  • In the Network Discovery/Rewalk panel, click the dropdown button next to Run Now and select Schedule



Customized Network Discovery or Rewalk

To schedule a customized Network Discovery or Rewalk targeting specific IP Address Ranges, referencing specific SNMP Credentials, and obeying custom settings:

  • In the Network Discovery/Rewalk panel, click Customize
  • Configure the Discovery/Rewalk as needed
  • Click the dropdown button next to Start Discovery and select Schedule



Ping-Only Discovery

To Schedule a Ping-Only Discovery:

  • In the Ping-Only Discovery panel, click Customize & Run
  • Configure the Discovery as needed
  • Click the dropdown button next to Start Discovery and select Schedule





  • Name the schedule to differentiate it from other Discovery schedules
  • Configure the Schedule Type and Start Date/Time
    • Once – run the Discovery once at the nominated date-time
    • Daily – (default) run the Discovery daily at a specified time
    • Weekly – run the Discovery weekly on a specified day and time
    • Monthly – run the Discovery monthly on a specified day and time
    • Advanced – run the Discovery according to a schedule specified in crontab syntax
  • Click Save

The schedule is saved, and you are returned to the Network Discovery configuration screen where you can:

  • Create additional schedules from the current Discovery configuration
  • Edit and/or manually run the Discovery
  • Exit the Discovery configuration screen
Note: Saving a schedule links the schedule to the specific Discovery configuration that was set when the Schedule screen was opened. After saving the schedule, you are returned to the Discovery configuration screen, but subsequent changes made to the configuration will not be reflected in a Discovery triggered by the previously saved schedule.
