Help needed, still didn't understand with new paramater of ICMPPING

[bee]

It's get frustrating with ICMPPING simple check. I've create an ICMPPING simple check. It's return ping successful (return 1) with following parameter: icmpping[,3] (picture-1) (3 times ping).

But it return ping fail (return 0) with following parameter: icmpping[,3,10] (picture-2) (3 times ping with 10msec interval)

and it's become not supported with following parameter: icmpping[,3,10,8] (picture-3) (3 times ping with 10msec interval and 8 bytes size of packet)

Did i misconfigured? What's wrong with all those parameter? I believe i did as what doc says.

Note:
* host is {always} alive during test.
* Zabbix Server (daemon) v1.8 (revision 9484) (7 December 2009)
Compilation time: Jan 21 2010 23:51:42
* FreeBSD 7.2-STABLE
* /usr/local/sbin/fping: Version 2.4b2_to $Date: 2002/01/16 00:33:42

Any comment much appreciate.

Thanks,

Hi,

But it return ping fail (return 0) with following parameter: icmpping[,3,10] (picture-2) (3 times ping with 10msec interval)

Not sure, maybe 10 ms is too short if your device is not on same network.

and it's become not supported with following parameter: icmpping[,3,10,8] (picture-3) (3 times ping with 10msec interval and 8 bytes size of packet)

From fping man page:

-bn Number of bytes of ping data to send. The minimum size (normally 12) allows room for the data that fping needs to do its work (sequence number, timestamp). The reported received data size includes
the IP header (normally 20 bytes) and ICMP header (8 bytes), so the minimum total size is 40 bytes. Default is 56, as in ping. Maximum is the theoretical maximum IP datagram size (64K), though
most systems limit this to a smaller, system-dependent number.

So I guess 8 is too small.

This what I get from command line:

# fping -s localhost -b 8           
fping: data size 8 not valid, must be between 12 and 65508

Hope this helps

Hi Alixen,
You solved my problem!!

The minimum interval each ping should 25msec (fping man)

Suggestion to ZABBIX team, please add minimum value of interval ping and packet size in the manual.

Thanks a lot!
