问题
I'm new to Prometheus but familiar with Influx (currently running 1.6).
My understanding is it's possible to configure Prometheus to remotely read data from influx with the following configuration in prometheus.yml:
remote_read:
url: "http://localhost:8086/api/v1/prom/read?db=bulkstats"
"bulkstats" is the database I'm trying to read data from in Prometheus. An example query that would work in influx would be:
SELECT "sess-curaaaactive" FROM "PDSNSYSTEM1" WHERE ("Nodename" = 'ALPRGAGQPNC') AND time >= now() - 6h"
However I cannot find one example of how to query that data from PromQL. Please help!

Here is the link which matches prometheus format with influxdb's one.
In terms of prometheus's jargon, in your example, sess-curaaaactive is the metric name (measurement in influx) and ("Nodename" = 'ALPRGAGQPNC') is just a label which prometheus attaches to the measurement to create a time series.
