Unable to load data from Zabbix server in CentOS to grafana Plugin

Hello Team, Am using grafana monitoring tool for last one year and now the server which runs Grafana goes down and we are unable to monitor the traffic. And i have installed Zabbix server and installed grafana plugin with Zabbix. But after installing the Grafana only one time i have got the traffic from the host. And still now not getting any traffic to Grafana. Can you please help me to fix it.

Is zabbix collecting the data ? In grafana > Datasources HTTP Settings are ok? Check if the username:password of the zabbix api are correct, and if the user you are using has the correct permissions (in zabbix to READ-write) on the host you want to collect data from.

Hi, Getting data from Zabbix server properly now. Thank you.
