I’d like to know if there is particular plan to support instant queries (accessed via “/api/v1/query”, not “query_range”) and when?
The reason is that we would like to use Grafana to display actual data from Prometheus (timestamps + values), without evaluation. While evaluation is great for requests with aggregations, we have case to display data “as is” using simple queries.
Please refer to https://groups.google.com/forum/#!topic/prometheus-users/FUfJNVwvsJw to see that Prometheus can return time series with actual data using instant queries (with time range), but Grafana does not support this mode yet.
I am aware of some attempts to add such support, but they were not successful so far, i.e.
https://github.com/grafana/grafana/issues/5765 (for table, we need same for graphs)
