Grafana / chronograf not showing the data

I have configured telegraf and data is sent to influxdb.
telegraf /etc/telegraf/telegraf.conf http_response -test
2020/05/30 07:35:37 I! Using config file: /etc/telegraf/telegraf.conf

But in chronograf or grafana dashboard it do not show anything.
when I click on host list it shows status as RED .
Any idea what is wrong?

If you enable the dubug logging (conf file debug = true) you can see how many point have been gathered since it prints the buffer size before flushing it.
You can also use chronograf explorer to freely navigate in your data, which is quicker than using the influx command line

Found issue and resolved.
