Local storage is stuck > 100%. I think it is interfering with the use of system.tag.storeTagHistory when importing data (migrating data) as I have little to no buffer to fill when importing. Thinking about reinstall but really would prefer a more surgical fix.
I've seen a few similar posts for vanilla Ignition with tag historian, but none of the solutions seem to fit. Anyway, thanks for any and all insight!
How many total data points do you have in your Edge historian? Limit is 35 days or 10 million entries, whichever comes first. The screenshot suggests you've hit the latter.
You should be deploying standard edition for such large history requirements.
I have multiple sites, with a local Ignition Edge install at each. The intent is to store and forward to headquarters where I have a standard install. I have no intent to store data locally at the edge.
I am using system.tag.storeTagHistory to import legacy data at the edge using scripting. My hope is that the data is forwarded with the same gateway identifier to make trending seamless from headquarters.
Is there any way to purge data after it is forwarded at the edge, or after a week or so? I cannot find any data purge settings for Ignition Edge. My local storage is full of data that probably already forwarded. Would it matter if I imported data out of sequence & from before the tag creation date?
Thanks for the reply!
Run that in your central gateway. Use a message handler there with system.util.sendRequest() on the Edge.
When I import from the central gateway, I can change the provider name, but the tag historian wants to store the data with the local gateway name. The data exists, and all is well, but I would have to merge data from 2 tags to create a seamless trend of legacy and new data or multiplex the tags somehow based on age.
Is there any way to override the gateway name when using system.tag.storeTagHistory similar to tag provider?
Hmm, no. I don't know how to do what you need. You could open a support ticket, but brace yourself for a "use standard edition" response.
Alternatively, is there any way to prune the local storage on Ignition Edge similar to standard? Thanks!
I don't know of any, other than shutting down to inspect the SQLite file.
