Calculated items doesnt work

[Guest]

Hi

if i take "last("net.if.in[eth1,bytes]")+last("net.if.out[eth1,bytes]")" i get the error of zabbix 1.8 Appliance => Incorrect key format 'key_name[param1,param2,...]'

Which Key is the right one or/and which change should i do ?

greetings

Hi,

Your syntax seems correct.

Do "net.if.in[eth1,bytes]" and "net.if.out[eth1,bytes]" items exist ?
Have you selected "Calculated" in Type drop down list ?

no.

Now i have select "calculated" have i out the line ""last("net.if.in[eth1,bytes]")+last("net.if.out[eth1,bytes]")" on key or on field "expression" ?

Should i do also to put any "value" on some fields ?

For key, you can use anything. e.g in.out.tot (up to you, but must be unique)

In Formula: last("net.if.in[eth1,bytes]")+last("net.if.out[eth1,bytes]")

For Type of Information, Data Type, Units, and Store Value, use the same as in the original items.

i could solve to accept the calculate item.
My problem is, the total calculate value is wrong.

actualy valua as example:
---------------------- ÁVG ---- max
Outgoing traffic 144.47 Kbps 447.93 Kbps
Incoming traffic 71.73 Kbps 145.36 Kbps
Total Traffic 1.07 kbps 54.95 kbps

should not have the right value of total avg: 216,47 AND max: 593,29 ?
last("net.if......... i take this on expression and as key is use random signs

what can i do more to calculate the right vlaues ?

Hi,

Post the whole configuration of your three items because without any detail we are just trying to second guess what you may have done wrong (as selecting the wrong type, as it happened before).
