|> range(start: 0, stop: now())

|> filter(fn: (r) => r["_measurement"] == “jmeter”)

|> filter(fn: (r) => r[“application”] == “demo_scenario.jmx @ 1 @ 2021-10-18T15:59:28Z”)

|> filter(fn: (r) => r["_field"] == “startedT”)

|> keep(columns: ["_time"])

|> sort(columns: ["_time"], desc: true)

|> last(column: “_time”)
