total disk space no data

[panzushan]

hello
I installed zabbix(3.2.4) on Centos7, and everything is ok before i add a graph about disk space usage on "/". When the time period is longer than 30min can be displayed, and graph shows no data when shorter than that.But sometimes it works well. And i try to zabbix_get found ok.So i don't konw what should i do.By the way, my server and client have time synchronization.

Forgive me for my English~~ Tks

It' s OK. Default update interval for items like "Total disk space" in Zabbix templates is 1 hour. Your odds to get this data via last 30min are 50/50.
