using graphite/influxdb with pickle format

Graphite Version : 3.0.3

I am following the example of using gatling with influxdb, looks like gatling uses graphite format to write data, and uses socket 2003 for plain text and 2004 for pickle format. I am trying to make it work using pickle format, but so far looks like its only writing in plain text, here is my config

graphite { light = false # only send the all* stats #host = "localhost" # The host where the Carbon server is located port = 2004 # The port to which the Carbon server listens to protocol = "tcp" # The protocol used to send data to Carbon (currently supported : "tcp", "udp") rootPathPrefix = "gatling" # The common prefix of all metrics sent to Graphite bufferSize = 8192 # GraphiteDataWriter's internal data buffer size, in bytes writePeriod = 1 # GraphiteDataWriter's write interval, in seconds }

the output when i run the wc -l 2004 command is

gatling.performancesimulation.Connected_Call.ok.count 9 1584379101 gatling.performancesimulation.Connected_Call.ok.min 28 1584379101 gatling.performancesimulation.Connected_Call.ok.max 206 1584379101 gatling.performancesimulation.Connected_Call.ok.mean 63 1584379101 gatling.performancesimulation.Connected_Call.ok.stdDev 52 1584379101 gatling.performancesimulation.Connected_Call.ok.percentiles50 40 1584379101 gatling.performancesimulation.Connected_Call.ok.percentiles75 55 1584379101 gatling.performancesimulation.Connected_Call.ok.percentiles95 206 1584379101 gatling.performancesimulation.Connected_Call.ok.percentiles99 206 1584379101 gatling.performancesimulation.Connected_Call.ko.count 0 1584379101 gatling.performancesimulation.Connected_Call.all.count 9 1584379101 gatling.performancesimulation.Connected_Call.all.min 28 1584379101 gatling.performancesimulation.Connected_Call.all.max 206 1584379101 gatling.performancesimulation.Connected_Call.all.mean 63 1584379101 gatling.performancesimulation.Connected_Call.all.stdDev 52 1584379101 gatling.performancesimulation.Connected_Call.all.percentiles50 40 1584379101 gatling.performancesimulation.Connected_Call.all.percentiles75 55 1584379101 gatling.performancesimulation.Connected_Call.all.percentiles95 206 1584379101 gatling.performancesimulation.Connected_Call.all.percentiles99 206 1584379101
