additionnate differents values from differents items in one item

[amazigh76]

hi,
i have a script in my encoder which count how many channels are decoding, this value reach to zabbix for differents encoders (Hosts) , i would like to create an item which additionnate all values from all server (hosts) to see the total number of decoding channel and graph it

for information, i have a template which count in one server how many channels are decoding, so i apply this template in all my encoders..

If I'm understanding your problem correctly, I think what you might want to look at is the use of aggregate checks:

thanks for your reply
yes i tried to use aggregate but i have multiple of errors...

where to create this new item because to create a new item i have to select an host... do i have to select a host ( an encoder )...?

then when i create item
i select type : Zabbix aggregate
then in key after select i have this exemple :
grpfunc[<group>,<key>,<func>,<param>]

in my exemple
grpfunc[<Encoder1,Encoder2,Encoder3,"nbenco[enco]",grpsum,last]

but it doesn't work many errors of syntax like this ...
Key "grpfunc" does not match <grpmax|grpmin|grpsum|grpavg>["Host group(s)", "Item key", "<last|min|max|avg|sum|count>", "parameter"].

is there something wrong in my syntax?

i create a new host named channel
then this item is enabled like this

grpsum[["ENCODER1","ENCODER2","ENCODER3"],"[nbenco[encoding]]",last,0]

but it is not supported because "no items for key "nbenco[encoding" in groups ENCODER1 ENCODER2...

i don't understand why "nbenco[encoding]" is the item which retrieve the value in each encoder it exists...

grpsum[["ENCODER1","ENCODER2","ENCODER3"],"[nbenco[encoding]]",last,0]

Try this:

grpsum["ENCODER1,ENCODER2,ENCODER3","nbenco[encoding]",last]

You have a lot of brackets in there that should be there. Also, you don't need to specify a time period if the function is "last".

Also, are "ENCODER1", "ENCODER2", and "ENCODER3" host groups, or individual hosts? They should be groups.

no there are in a group i have no rights to create a group ...
and it is not work without [ ] ....

thanks for your help

I think that's the problem then. grpsum needs groups.

thanks;
i create a specific group encoders i will see after update if it works
thanks a lot ))

I think that's the problem then. grpsum needs groups.

the problem was due to the group it is working fine now )
