ICMPPING problem

[AndWei]

Hi,

i'm new here and already have a question:
I want to monitor a DSL connection with a dynamic IPv4 address. The address is reported to Zabbix and stored a plain text item named 'inetip'. I created a second item using "Simple Check" -> Key: icmpping[{inetip.last(0)}.

The item fails with the message 'fping6 Temporary failure in name resolution'. Why is Zabbix using fping6?

Hosts that are linked to the default template 'ICMP Ping' are checked without any problems.

Kind regards ...

You need to tell zabbix that it has to read the contents of the file. Simply specifying "ping filename" cannot work.

You have to do some script magic for that. The easiest way is to do it via a "UserParameter" script. See the docs for that.

Hum, no.

This is the script i'm running:

DATA=$(snmpgetnext -v1 -c public 192.168.1.1 ipAdEntAddr.0)
if [ $? == 0 ]; then
echo $DATA | awk '{print $4}'
else
echo 0.0.0.0
fi

The resulting value is stored in Zabbix as an item named 'inetip' (Type of information: Text). I created a second item using "Simple Check" -> Key: icmpping[{inetip.last(0)}.

But it does not work, the resulting error is 'fping6 Temporary failure in name resolution'.

Why don't you ping directly in your snmpget script and send the result?

That's not the solution i'm looking for, and would feel like a kludge to me

There must be a reason, why Zabbix uses 'fping6' instead of 'fping'.

Have you checked /etc/zabbix/zabbix-server.conf?
/etc/zabbix/zabbix-server.conf:# Location of fping.
/etc/zabbix/zabbix-server.conf:# Make sure that fping binary has root ownership and SUID flag set.
/etc/zabbix/zabbix-server.conf:# FpingLocation=/usr/sbin/fping
/etc/zabbix/zabbix-server.conf:# Location of fping6.
/etc/zabbix/zabbix-server.conf:# Make sure that fping6 binary has root ownership and SUID flag set.
/etc/zabbix/zabbix-server.conf:# Make empty if your fping utility is capable to process IPv6 addresses.
/etc/zabbix/zabbix-server.conf:# Fping6Location=/usr/sbin/fping6


Or could it be that on your system fping is symlinked to fping6?

That's the two files:
[root@zabbix ~]# ls -l /usr/sbin/fping*
rwsr-xr-x. 1 root root 27856 Apr 17 2012 /usr/sbin/fping
rwsr-xr-x. 1 root root 28208 Apr 17 2012 /usr/sbin/fping6

If used from the shell:

[root@zabbix ~]# fping6 91.53.249.112
fping6: Address family for hostname not supported

[root@zabbix ~]# fping 91.53.249.112
91.53.249.112 is alive

The correct error in Zabbix is:
"fping failed: "fping6: Temporary failure in name resolution"

I'm running Zabbix 2.2.2 from the Zabbix repository on CentOS 6.5 x64.

Edit: Could it be, that Zabbix does not support variables in ICMPPING and mistakes '[{inetip.last(0)}' for a hostname? If so, why would it use fping6

[steveboyson]

fping6 is most likely the IPv6 version of fping. If you have no IPv6 addresses configured it gives an error message.

I don't think that any of Zabbix' functions can take the last value of a different item as an input parameter - that is what I wanted to explain previously.

They accept macros but no other item values.

Looks like it. Thank you.
