            batch query is not allowed to request data from "".""
            Asked 2020-May-15 at 11:41

            I'm getting started with Kapacitor and have been trying to run the first guide in the Kapacitor documentation, but with data I already have. I managed to define a task, but I can neither enable it nor can I run a backfill. I came across this question, which is similar to my problem, but the answer there didn't help. In contrast to the error message there I get empty strings for database, retention policy, and/or measurement.

            In Kapacitor config I set an InfluxDB connection to the local host instance with the name localhost (which has a database mydb and the measurements weather.current.clouds and weather.current.visibility with default retention policy autogen) and created the following weathertest.tick script:

            Python cron job vs Kapacitor UDF
            Asked 2020-Mar-02 at 15:20

            I need to perform some background advanced calculations on my data after it is collected in InfluxDb which is stored on the edge server, which means I have limited resources for the calculations. Also I cannot block the data collection while I do calculations. I am weighing using Kapacitor UDF streams vs custom Python scripts.

            Please note I need to make the scripts configurable so that I can easily deply them to different environments with different sensors



            Answered 2020-Mar-02 at 15:20

            It probably makes little difference, in general, especially for 'simple' usecases, though I lean towards standalone python scripts. (It may be better to use Kapacitor if you can cover your usecase using the kapacitor language for this instead of python based UDFs, but I found it insufficient since I needed to retrieve additional data from other databases)

            • Standalone python scripts could be a bit lighter, since you don't need to run the Kapacitor service.
            • Standalone python scripts could be a bit more configurable. Kapacitor is also pretty configurable but you'd have to spend a bit of time learning how to use it.
            • Standalone python scripts could be a bit more stable. I've experimented with python UDF's a couple of years ago and found them unstable and buggy. While this may have improved by now, you'd still be relying on this being supported and if go is not your language you might have trouble debugging and fixing issues yourself.

            How to use Micrometer for metrics collection on TICK stack without using Spring or Spring Boot?
            Asked 2020-Jan-15 at 01:16

            I am writing an app in pure Java without using Spring/SpringBoot or any other frameworks. I am using the TICK stack (Telegraf, Influx, Chronograf, and Kapacitor) as my metrics backend and viz platform. I am using Telegraf with Statsd plugin activated on localhost 8125. The problem is that my app is not sending any metrics to the system. However, I wrote a simple Spring Boot app which pushed the relevant metrics to my dashboard. Also, doing an echo "api.msgs.ok:10|c" | nc -C -w 1 -u localhost 8125 pushes the metrics to my dashboard as well.

            The sample code I am trying to run is here:



            Answered 2020-Jan-15 at 01:16

            Publishing of StatsD metrics is asynchronous, and this example simply terminates too quickly. Put a Thread.sleep(1000) at the end, and metrics are published fine.
