Netrics Built-In: Latency under Load (OpLat)

[marcwitasee]

Port the latency under load module from Netrics v1 to v2.

The latency under the load module should measure the ping latency (ICMP and TCP) to a given target while saturating the link with an iPerf3 test using the OpLat tool.

The module should take the following default parameters for the binary:

• Client set to abbott.cs.uchicago.edu (-c abbott.cs.uchicago.edu)
• Port set to 33301 (-p 33301)
• Destination set to abbott.cs.uchicago.edu:33317 (-d abbott.cs.uchicago.edu:33317)
• Set the interval time between pings to 0.25 (-i 0.25)
• Set the number of pings to 10 (-n 10)
• Use both the ICMP and TCP protocols (-m 'tcp icmp')
• Set output to JSON (-J)
• Test both the upload and download using the -R flag

The module should produce the following data fields:

• Average rate of TCP probes
• Average rate of ICMP probes
• Unloaded/loaded ICMP/TCP packet loss (Up/Down)
• Unloaded/loaded ICMP/TCP RTT min (Up/Down)
• Unloaded/loaded ICMP/TCP RTT max (Up/Down)
• Unloaded/loaded ICMP/TCP RTT avg (Up/Down)
