Given "Custom Anomaly Detection" example is not working

[kchakraborty]

I have followed exact same steps but it is showing an error like

"run: open server: open service *udf.Service: failed to load process info for "tTest": write error: write |1: broken pipe"

please suggest

@kchakraborty Are there any other logs? The UDF process is crashing and that is why you are getting the broken pipe error

@kchakraborty . Got the same issue. See more logs in /var/log/kapacitor/kapacitor.log You may have to install python dependency. Install using pip install protobuf Also, if you see any error saying udf_pb2 is not globally defined, then update ttest.py file, fourth line to

from kapacitor.udf import udf_pb2

I'm having the same or similar issue. This is what the output from kapacitor.log looks like repeating over and over. Restarting kapacitor doesn't quite help. Ocasionally however it manages to start properly and process a few points all with the same code for my udf.

I also encountered the same problem. Is this problem solved? Can you provide a solution？
