I will be receiving source data in json format.
What is the best option to get into influxdb (or any other db) so Grafana
can read data and render dashboard please?
Thinking of these
what is the best db in my scenario?
We don’t know unless you tell us what your scenario is
For example: what sort of data are you delaing with, how many samples per
second / minute / hour are you expecting to receive, what sort of queries do
you need to do on that data to get Grafana to show it to you?
or we should have a plugin to covert json to influxbd (going to request
influxdb support as well)
See above - use telegraf.
Just to make things clear (since you mention a “plugin”) - Grafana does not
store data. Grafana helps you to visualise the data which it fetches from a
back-end data store, such as InfluxDB. There are many different data stores
which Grafana supports, and the best one for your needs will be determined by
the type and quantity of data you’re dealing with, the type of queries you
need Grafana to do on it (Grafana can only perform queries supported by the
data store query language) and, to some extent, which you are most familiar
