UserParameter not supported

[eerien]

I added following UserParameter.

UserParameter=icmp.ping.loss[*],fping $1 -C 5 -q 2>&1 | awk '{loss=0; cnt=0; for (i=3; i<3+5; i++) { if (length($i)>1) { cnt ++; } else { loss++; }} if (cnt > 0) { print 100*loss/5; } else { print 100; }}'

Prettified version of awk script..

{
    loss = 0;
    cnt = 0;
    for (i = 3; i < 3 + 5; i++) {
        if (length($i) > 1) {
            cnt++;
        } else {
            loss++;
        }
    }
    if (cnt > 0) {
        print 100 * loss / 5;
    } else {
        print 100;
    }
}

I tested this as following.

# fping 127.0.0.1 -C 5 -q 2>&1 | awk '{loss=0; cnt=0; for (i=3; i<3+5; i++) { if (length($i)>1) { cnt ++; } else { loss++; }} if (cnt > 0) { print 100*loss/5; } else { print 100; }}'
0
# echo "54.248.208.246 : 41.89 40.80 42.49 46.02 -" | awk '{loss=0; cnt=0; for (i=3; i<3+5; i++) { if (length($i)>1) { cnt ++; } else { loss++; }} if (cnt > 0) { print 100*loss/5; } else { print 100; }}'
20

But, when I test this by zabbix_agentd -t, it isn't working.

# zabbix_agentd -t icmp.ping.loss[127.0.0.1]
icmp.ping.loss[127.0.0.1]                     [m|ZBX_NOTSUPPORTED]

I can't understand why this is not working...

1. How can I solve this problem?
2. Are there any debugging tool or logging to debug UserParameter command?

Thank you so much!

Why do that as a UserParameter when Zabbix server will do it natively?

[eerien]

I want monitor network status from any specific server to others, not zabbix server to others.

[eerien]

Not sure, but zabbix may parse incorrectly '$i'.
I tried with $$i, but it's not working too.

[eerien]

This is not working too.

UserParameter=icmp.ping.loss[*],ping $1 -qc 5 | grep loss | awk -F '[% ]' '{print $$6}'

I cant' understand what happen..

[eerien]

OMG. It is Timeout problem.
I increase Timeout parameter to 10, it is solved.

Thanks a lot.

I added following UserParameter.

UserParameter=icmp.ping.loss[*]

Zabbix uses fping natively in icmpping[], icmppingloss[] and icmppingsec[]keys.

Seems you are trying to reinvent the wheel

[eerien]

to kloczek,

I want monitor network status from any specific server to others, not zabbix server to others.

[kloczek]

That is fine.

FYI: you should be doing something like this only if for example your application is using ICMP as communication protocol. Otherwise you should be checking connections and availability of physical paths on ports/protocols used by your application(s).
Sometimes ICMP loses or latency may be completely different than on TCP/UDP. Sometimes ICMP may me even using completely different physical paths.
Generally ICMP should be only additional indicator that something may be wrong. So limiting ICMP checks to simple checks from server/proxy it is exactly what probably you need.

Thank you for your good advice.
