Hi!
We faced that Grafana plugins, such as grafana-simple-json-datasource, become obsolete too often and unpredictable.
We decided not too use special plugins to integrate Rapid SCADA and Grafana. With Rapid SCADA 6.x you should configure archives to store historical data into database, then display data by Grafana. I suggest storing historical data to PostgreSQL.

Could you please check short instructions for working with Grafana
PostgreSQL data source and Rapid SCADA.

Work at Grafana:
1. Choose as data source PostgreSQL.
2. Set the data source’s basic configuration options in setting tab.
For example:
Host: The IP address/hostname your PostgreSQL instance
Database: rapid_scada
User: postgres
Password: Database user’s postgres password – postgres
3. Write a sql-query. You can use Query builder or Query editor.
4. Simple query example (Query on one channel, not including into stat = 0, and also not showing a gap, if there is no data in a certain period of time)

SELECT
time_stamp AS "time",
val
FROM mod_arc_postgre_sql.mincopy_historical
WHERE
cnl_num = 101
ORDER BY 1

Could you please provide response from Grafana?
Grafana Data Provider API represents parameters transmitted to Grafana for build graph and converts the specified date and time to the unix milliseconds.

Could you provide versions ScadaServer, ModDBExport and PostgresSQL?

Hi!
Probably, you can see the error ‘Could not read remaining length’.
The exception occurs when there is no data to read or the connection is no longer valid.
You can test the following update https://yadi.sk/d/HPI_FkFPfrXbhA
