Extract timeout from ping command and write it to variable.

RouterOS Scripting
1

Please get help. I need a to run any ping (with count=1) command and write timeout to variable.

I plan to send this values to influxdb for both external ifaces (dual wan). So it is important that the interface is specified.

I tried many cases. But cannot found a working solution.

I apologize for the extra code - this is an outline for now.

Case 1. Here I cannot save timeout to variable:

[admin@MikroTik] > /ping address="8.8.8.8" count=1
  SEQ HOST                                     SIZE TTL TIME  STATUS                                                                    
    0 8.8.8.8                                    56  56 27ms 
    sent=1 received=1 packet-loss=0% min-rtt=27ms avg-rtt=27ms max-rtt=27ms 
 # how to get avg-rtt at line here in the variable ?

Case 2. Here I cannot understand how it works, and why it works not as expected.

:log info "my script started"
:local pingIp "87.250.250.242"
:local pingCount 1
:local pingInterface "pppoe-rt"
:local pingStatus

:local avgRtt

:local influxurl "http://192.168.129.2:8086/write?db=icmp"

:log info "my script middle"

:while (true) do={
  :log info "icmp-monitoring: while start"
  /tool flood-ping $pingIp count=$pingCount do={
    :if ($sent = 2) do={
      :set avgRtt $"avg-rtt"
      :log info "sent for $pingIp is $sent"
      :log info "avgRtt for $pingIp is $avgRtt"
    }
  }
  /delay delay-time=5s
  :log info "icmp-monitoring: while end"
};


:log info "my script ended: $influxurl"

Here is what it writes to logging:

15:20:30 script,info icmp-monitoring: while start 
15:20:30 script,info sent for 87.250.250.242 is 1 
15:20:30 script,info avgRtt for 87.250.250.242 is 0 
15:20:31 script,info sent for 87.250.250.242 is 1 
15:20:31 script,info avgRtt for 87.250.250.242 is 38 
15:20:32 script,info icmp-monitoring: while end 
15:20:32 script,info icmp-monitoring: while start 
15:20:32 script,info sent for 87.250.250.242 is 1 
15:20:32 script,info avgRtt for 87.250.250.242 is 0 
15:20:33 script,info sent for 87.250.250.242 is 1 
15:20:33 script,info avgRtt for 87.250.250.242 is 37 
15:20:34 script,info icmp-monitoring: while end 
15:20:34 script,info icmp-monitoring: while start 
15:20:34 script,info sent for 87.250.250.242 is 1 
15:20:34 script,info avgRtt for 87.250.250.242 is 0

Hi skubriev,

This may do what you require. You can add any additional stats you require from the flood-ping tool.

Cheers,
Icosa.

# IP ADDRESS TO PING
:local ipping 8.8.8.8
# PING COUNT SET
:local cnt 1
:local rtt
:local avgrtt
[:tool flood-ping address=$ipping count=$cnt do={
	:if ($sent=$cnt) do={
		:set rtt ($"max-rtt")
		:set avgrtt ($"avg-rtt")
		}
	}
]
:put "Average RTT: $avgrtt and MAX RTT: $rtt"
