Unable to parse: invalid boolean when sending data from fluentd

[xuoguoto]

I am sending some metrics from fluentd to Kapacitor OSS version 1.5.9 for stream processing. Using fangli/fluent-plugin-influxdb as the fluentd plugin to send data to Kapacitor in version 1 lineformat.

From the packet capture I can see that , this is the line thats being sent to Kapacitor:

nodeexporter09,_seq=6 host={"network"=>{"out"=>{"bytes"=>1329771, "packets"=>457},
 "in"=>{"bytes"=>1309413, "packets"=>461}}, "name"=>"myhost"} 1620454532615

Which gets the error: unable to parse: invalid boolean

Fluentd sends multiple points in a single HTTP request, and all of them are rejected by Kapacitor with same error message.

My questions are:

1. Is this a valid line in line protocol? I could't find its definition in reference docs, esp the usage of {} and _seq?
2. If so, what could be the error here

Any update on Kapacitor supporting Influx2.0 line protocol. I am successfully able to send data from fluentd to InfluxDB2.0, but since InfluxDB2.0 do not support streaming, I have to send a copy of data to Kapacitor too.

This was a problem with fluent-plugin-influxdb. Fixed and submitted a PR at fangli/fluent-plugin-influxdb#107.

This issue can be closed.

It would be interested to know when or if Kapacitor can handle Influx2.0 line protocol.
