Using default Macro in items keys

[Frogg]

Hi,

in the doc there is the default macros available : https://www.zabbix.com/documentation...ed_by_location

Why can't i call them in items key like :

icmpping[{HOST.NAME}]

i tryied {HOST.NAME} / {HOST.DNS} / {HOSTNAME}
deseperatly i even tried {$HOSTNAME} / {$HOST.NAME}
and even

 icmpping[{HOST.NAME},,,,]

Without success

each time i get the error

Cannot send ICMP ping packets to this host

any idea and what going on ?

By the way if i set the hostname directly instead of the macro in the command it works

Thanks.

The macro {HOST.HOST} returns the name of your host, configured in Zabbix frontend. Are you sure you named it by real host name that is pingable on your network?

Thank for the reply,

i just tried it, same result:
"icmpping[{HOST.HOST}]" became not supported: Cannot send ICMP ping packets to this host.

If i use the host string name like icmpping[hostname] with hostname the computer name it works.

Exemples:

Ping in ssh (OK) :

ping frogg.home
PING frogg.home (192.168.0.50) 56(84) bytes of data.
64 bytes from frogg.home (192.168.0.50): icmp_seq=1 ttl=128 time=2.60 ms
64 bytes from frogg.home (192.168.0.50): icmp_seq=2 ttl=128 time=2.76 ms
64 bytes from frogg.home (192.168.0.50): icmp_seq=3 ttl=128 time=2.53 ms
64 bytes from frogg.home (192.168.0.50): icmp_seq=4 ttl=128 time=2.76 ms
64 bytes from frogg.home (192.168.0.50): icmp_seq=5 ttl=128 time=2.15 ms

With name as string (OK):

icmpping[frogg.home]

With name as macro (KO):

[B]"icmpping[{HOST.HOST}]" became not supported: Cannot send ICMP ping packets to this host.[/B]

By the way i have the same trouble when i try to assign default macro in the template like (KO)

Macro	Value
{$SSL.DNS}	{HOST.DNS}

If i use {HOST.DNS} directly in external script all is ok (OK)


Version:
i am using Zabbix 4.4.6 btw.

{HOST.HOST} is translated to the name of the host, see picture:


Yeah, and this:

Macro Value
{$SSL.DNS} {HOST.DNS}

won't work because macros are not supported in macro values.

Thanks for the answer,

What about simple check items ? like

  
 icmpping[{HOST.HOST}]

i get

"icmpping[{HOST.HOST}]" became not supported: Cannot send ICMP ping packets to this host.

This is the problem i get.

{HOST.HOST} (even other internal macros) is (are) working well in title, map, external script ... i didn't find trouble atm with it.

Thanks.

Could you show the screenshot of your item configuration (Configuration -> Hosts -> click your host -> Items -> click your item). The screen shot of whole page.

[Frogg]

Thanks again for your answser.


I would like to tell what happened but i cant.

Today i got a big network trouble (almost all my newtork went down/up for 10 min alternativelly), lot of thing was no more working. I even had to reboot the zabbix server.


What i know it is that now the script is working... i didn't modified anything. (maybe the reboot solved it, i dunno ?)



I dont understand what happened, and i am sorry to bothered you with this, as all is working as it should...
I swear i didnt change the configuration after the trouble i get.

I am really sorry about it.

[dimir]

No problem at all! I'm glad it's working for you. Looks like your host has correct name. The only thing I can think of - server configuration cache reload that by default happens every minute, but perhaps you have modified this value (CacheUpdateFrequency=60 in zabbix server config file).
