 Description   

I've created an item with Simple check "icmppingsec", ex:
icmppingsec[10.0.0.1,,,3000]
In the latest data it has showed as 1s 74.6ms.

But if I've pinged the host from console, I've got 314 ms, ex:

zabbix:/home/AIRPORT/kbp/zabbix-2.4.5# fping -sC3 10.0.0.1
10.0.0.1 : [0], 84 bytes, 313 ms (313 avg, 0% loss)
10.0.0.1 : [1], 84 bytes, 317 ms (315 avg, 0% loss)
10.0.0.1 : [2], 84 bytes, 312 ms (314 avg, 0% loss)

10.0.0.1 : 313.54 317.04 312.42

1 targets
1 alive
0 unreachable
0 unknown addresses

0 timeouts (waiting for response)
3 ICMP Echos sent
3 ICMP Echo Replies received
0 other ICMP received

312 ms (min round trip time)
314 ms (avg round trip time)
317 ms (max round trip time)
2.321 sec (elapsed real time)

It's similar situation with other IPs, ex:
icmppingsec[57.5.64.250,,,1000] is 553.4ms
but
fping -sC3 57.5.64.250 is 314 ms

The average is meant to be different each time fping runs, so the fact that the manual fping invocation differs from Zabbix fping invocation does not indicate a bug per se. Could you please attach DebugLevel=4 of the pinger that shows fping output and Zabbix calculated average?

take into account (3) in ZBX-5893

Sorry, I've missed a comma in the Simple check key. It must be: icmppingsec[10.0.0.1,,,,3000]
The issue doesn't exist.
