I have this table in Grafana that I’ve been using for a couple of years now. The data is pulled by Telegraf into InfluxDB (1.8) and shown in Grafana like below. We are using v9.3.8 (Docker). If we upgrade to 9.4.x then the lines in the table that have empty cells are now completely removed. For example in the total of 4 lines below highlighted will no longer be present as they have no value under ‘Maint Voltage’. Grafana 9.4.x only wants to show lines in a table that have values it seems, if one value is missing the entire line is removed from the table.
What you can do is use the Value Mapping, I have created this .GIF in which I have a column with empty fields and what I did is use the Special match inside value mapping and replace them with 0 (you can use 0 or false or anything to represent those empty fields)
That didn’t seem to work either. I did try a graph for that value and 1 device that goes wrong when we upgrade to 9.4.x and it comes back with no data. Could it be how 9.4.x sees the data for this value in InfluxDB?
I’ve I removed that field column that all come in, so it just doesn’t like the fact the cell is has not value at all, (not a 0 as the DB has no entry).
