Background : There are two gateways connected to each other, the central gateway and the edge gateway. Both the gateways are connected to PostgresSQL database server which unfortunately is down. The historical values that used to be stored in the database and were used to generate the report afterwards are hence unable to obtain.
Is there any way to get access to the historical values of the tags particularly of the tags belonging to the edge gateway? I see that the values are quarantined in the ignition gateway now. The database server will take few days to be recovered.
I would try making a new datasource (one that works ) and use it as the failover source for the original datasource.
That would indeed be taken into consideration moving forward but currently I am worried about getting access to those unlogged historical values seemingly quarantined in the gateway.
There is no readily available way to read that data from quarantine; quarantine is meant for consumption by Ignition, not to act as a general purpose database substitute.
My tool Kindling can be used to look at S+F cache files and export the data within - but it's going to take some effort to reimport them back into a database for use as a temporary historian. It's also going to be a one-time snapshot process, not continuous access to the quarantined data, which is presumably continuing to grow.
