Monitoring Options​

  • IP Range: Select the IP range that will be checked for new SNMP devices.
  • SNMP Profile: Define the connection details for the SNMP discovery process.
  • SNMP Version: Select the version of SNMP the event monitor will use to connect.
  • Community: Enter the community used to authenticate with SNMP.
  • Port Number: Enter the port number, default is 161.
  • Timeout: Enter the number of milliseconds the event monitor will try to connect before timing out.
  • Retries: Enter the number of retries the event monitor will perform before giving up.
  • Detection: Use "Check with ping first" to detect devices using pings and then use SNMP if the device responds, or "Check only using SNMP" to detect devices only using SNMP.
  • Device Group: Select a network device group for adding new devices detected by this scan.
  • Device Name: With "Use reverse DNS" selected, the event monitor will attempt to detect a DNS host name for the IP address of discovered devices, using the host name to add the device; otherwise, the IP address will be used.
  • Display Name: Choose how display names for detected devices are selected, either "Use the device name" for IP address or host name, or "Use system.sysName.0" to use SNMP retrieval if available.
  • Name Format: Determines how detected host names are formatted.
  • Tag Discovery: Detect SNMP values and map them to tags for monitoring and management, like system.sysLocation.0 to add as a tag on devices.
