Issue in connecting remote InfluxDB from local Kapacitor

[hatim-stovewala]

Hi, I want to connect an remote instance of InfluxDB from my local Kapacitor and do some processing on the data and put back the processed data to the same remote instance of InfluxDB. I have made changes to the kapacitor.conf file changing the urls parameter to desired remote Influx's IP something like urls = ["http://10.0.10.10:8086"] By doing this Influx have correct subscription mapping of this kapacitor instance. I will be posting output below. However, when I try to run a batch task, it runs well. Data get picks from remote Influx and processed data is put back into the remote Influx. But when I run stream task, it doesn't run. The ouput is null. In kapacitor show task everything is with value 0.

Could you please help me setting up this.

Kapacitor is spinning on docker on Linux machine and the InfluxDB which I'm trying to connect is somewhere on the network.

InfluxDB is trying to send the data to Kapacitor using this url http://ef12c0ed23ed:9092. Is that a valid url that the InfluxDB host can resolve? If not change the hostname setting for Kapacitor to be a resolvable name.

[hatim-stovewala]

The hostname is 'localhost' in the kapacitor.conf. Do I need to change it to 'ef12c0ed23ed'? However if this is the case, I'm just wondering how batch tasks runs properly with 'localhost' settings but stream task doesn't.

@hatim-stovewala could you please provide your "batch" and "stream" tick scripts?

[zhoujinl]

how to change ef12c0ed23ed ?

[wuqifhb]

@zhoujinl change hostname on top of kapacitor.config
