Hello I am faced with error:
error:“tsdb.HandleRequest() error rpc error: code = Unavailable desc = transport is closing”
I try to use alerts of bandwidth usage with Grafana and Zabbix datasoucre.
Grafana version is v7.4.0 (c2203b9859)
Zabbix Plugin is 4.1.4
I run them under Raspberry Pi3.
My Grafana renderer is
[adejong/grafana-image-renderer-pi:1.0.8-beta2]
And it’s available at 10.10.20.20:32773 in CoreElec 9 under Docker.
My zabbix and grafana are available under Raspberry Pi3 with the same IP address 10.10.10.4, zabbix uses port 80, grafana uses 8080.
I will share the results of test rule.
Any idea?
