Problem with coleting itens

Hello, I have a problem with Grafana.

I have the data being collected normally in zabbix, but Grafana doesn’t pull it in at the correct time…

For example: I have an item from the windows template that collects the space used by the machine, zabbix has just collected the data, and I can wait for hours, but in grafana the “no data” field will continue to appear. I’ve already worked on the times ranges and I couldn’t solve it… does anyone have an idea what this could be?

It only happens to some items, not all.

I’m using the standard windows template, monitoring a TS machine(windows server 2012)…
