There is a wide choice of predefined Probes, and you can also add new ones. Double-click an existing Probe to see how it was set up, or to adjust it's settings.

Adding new probes

There are several probe types, they are:

  • DNS - Sends DNS resolve request with specified name to resolve, and optionally checks if response matches the specified IP addresses (at least one of them)
  • Function - Performs custom functions to decide if service is up. If the device is up, can graph data of another function
  • ICMP - Sends ICMP echo requests (pings) of specified packet size and TTL. Can try a number of times, and specify retry interval.
  • Logic - Logic probe invokes other probes and performs logic operations based on results
  • Random - Randomly decides if service is up, or not. Can specify up chance. Useful for testing.
  • SNMP - Will query specified OID and service will be up, if a response is received and result of comparison is a logical true
  • TCP - Generic TCP probe, can be used for various protocols. Can send and wait for specific responses
  • UDP - Generic UDP probe, can be used for various protocols. Can send and wait for specific responses
