Ping

Description

Ping is a network test that allows an agent to verify whether it can reach an IP device. The test also reports the Round Trip Time (RTT), expressed in milliseconds, between the agent and the remote device. Ping uses the ICMP echo-request/echo-reply protocol.
 
Ping tests can be configured on the Target Setup form.
 
You can also run an ad-hoc ping test with Ad-Hoc Testing.
 
 
Procedure
 
Input the following fields:
  1. Destination (required for version 0.11.1 or and earlier, determined via Resource in version 0.11.2): The IP address or hostname of the remote device.
  2. Count (required): This number tells the agent how many ICMP echo-request packets it should before exiting. The default value is 0.
    1. Leave it to 0 if it's a permanent/ongoing test.
    2. Specify the number of packets to send before exiting.
  3. Interval (required): The interpacket leave, that is the time in seconds interceding between two consecutive ICMP echo-request packets. The default value is 1 second.
  4. Timeout per datapoint (required): The number of seconds that the agent will wait for a ICMP echo-reply before declaring that datapoint failed. The default value is 5.
  5. Test Type: Choose between ICMP (default) and TCP.  The TCP ping test enables NetBeez agents to verify availability and performance of TCP/IP services.  If you select TCP:
    • Port Number: Input the port number
    • Flags: Check all applicable flags
  6. Specify MTU size (optional): Click on the checkbox if you would like to increase the default packet size of the PING packets. By default a PING packet sends 64 bytes on the network - 56 bytes are payload data and 8 bytes are the header.
    1. DF set: Set the Don't Fragment bit in the ICMP echo-request packet to avoid fragmentation.
    2. DF not set: Don't set the Don't Fragment but in the ICMP echo-request packet.
  7. Select TOS/DSCP Class (optional):  Select one of the options from the drop-down list.  The default is no TOS flag.
