Hi,
I run logstash 6.5.4 on docker. It work normally before I install the plugin：logstash-output-influxdb 5.0.5
my logstash's output\_config:
if "firewall\_traffic" in [input\_type] {
if "noop" in [trandisp] or "snat" in [trandisp] or "dnat" in [trandisp] {
influxdb {
db =\> "traffic"
host =\> "influxdb"
port =\> "9086"
coerce\_values =\> {
"sentbyte" =\> "integer"
"rcvdbyte" =\> "integer"
"sentpkt" =\> "integer"
"rcvdpkt" =\> "integer"
"srcport" =\> "integer"
"dstport" =\> "integer"
"proto" =\> "integer"
}
measurement =\> "%{trandisp}"
send\_as\_tags =\> ["devid", "service", "status", "subtype","localip"]
data\_points =\> {
"app" =\> "%{app}"
"srcip" =\> "%{srcip}"
"srcport" =\> "%{srcport}"
"dstip" =\> "%{dstip}"
"dstport" =\> "%{dstport}"
"sentbyte" =\> "%{sentbyte}"
"rcvdbyte" =\> "%{rcvdbyte}"
"sentpkt" =\> "%{sentpkt}"
"rcvdpkt" =\> "%{rcvdpkt}"
"proto" =\> "%{proto}"
"devid" =\> "%{devid}"
"service" =\> "%{service}"
"status" =\> "%{status}"
"subtype" =\> "%{subtype}"
"localip" =\> "%{localip}"
}
}
}
}
when I gen this json data to logstash:
{
"app" =\> "HTTP",
"subtype" =\> "forward",
"input\_type" =\> "firewall\_traffic",
"sentbyte" =\> "43085",
"rcvdbyte" =\> "29883",
"sentpkt" =\> "162",
"status" =\> "accept",
"host" =\> "10.1.101.69",
"devid" =\> "123456",
"localip" =\> "192.168.32.96",
"dstip" =\> "110.231.234.204",
"dstport" =\> "43050",
"service" =\> "HTTP",

when it happens, I can't see any logs in influxdb sever after I enable the influxdb's debug config.
