Does not return a value from Zabbix

Hi i have Zabbix 3.2.2 and Grafana v4.6.2
Im try to create metric about disk usage on my servers.

Adding Query is good, i see all of my items, but if i choose item “Mounted filesystem discovery” i see nothing on graph. In Query Inspector response 0 -

xhrStatus:"complete"
request:Object
method:"POST"
url:"api/datasources/proxy/1"
data:Object
jsonrpc:"2.0"
method:"trend.get"
params:Object
id:1
auth:"9bb8ca582de3d888135e56dfa8f75c44"
response:Object
jsonrpc:"2.0"
result:Array[0]

In grafana.log nothing interesting

But another items on server shows good on graphs and correctly see in Query Inspector.
Same in the “latest data” on my zabbix server i see all data from all items was returned from server.
My item is “Item prototypes” from “Discovery Rules” looks like this - "vfs.fs.size[{#FSNAME},free]"
What’s i do wrong?

Hi,

Are you using the Zabbix plugin for Grafana?

Marcus

Yes it is
forgot say about them

Hi,

So if you check the “Mounted filesystem discovery” graph in Zabbix there is data, but not when you try to visualize it in Grafana - that’s your question?

Marcus

Yes, absolutely right!
Have ideas, why this happens?

Hi! I’m not sure you’re doing it right. Mounted filesystem discovery is Discovery rule in Zabbix template, not an item. You should select metric like Free disk space on /, depends on what you want to get.
