Currently there is an ingestion limit of 1 MB active on the Dev ingestion service. For a couple of dashboards in the Dev instance of UNIFYMonitor, the data being pushed in each package is much larger than 1 MB and all incoming packages fail to be ingested into Data Explorer. Development can not be done on these dashboards as no current data is available.
We have backlogged features for splitting the data into pages. We've removed the 1mb restriction on ingest, I believe the next limit is 30mb which is large for a text-based request body.
