Hi,
I am having some issues getting MFlib and Prometheus setup.I have been following the setup instructions from notebooks found here: https://github.com/fabric-testbed/jupyter-examples/blob/1c9097e416ac1fdb370489b5b4fd6e0e0bf76dbe/fabric_examples/mflib/KNIT6/KNIT6_start_here.ipynb
In the process I am having some issues getting prometheus set up. Specifically in the
#instrumetize_results = mf.instrumentize()step, where I am getting an error in the setup of prometheus. The error can be seen below asError 1. In the same process I attempt to access grafana locally by tunneling throughmf.grafana_tunnel, and through this I can access the node using ssh, however I then get spammed with the errorchannel 3: open failed: connect failed: Connection refusedError 1:

Instrumentize Process Complete.Extra info: I initially had this as part of a more complex project, and prometheus worked for me at first. This was last week. Then in the last few days I started getting this error, so in an effort to debug I made a more simple version just following the guide from the github repo. The error persists. I don’t know if my issues are site related since I don’t remember what sites I was using initially, or if something else is causing it.

Thanks for bringing this to our attention.
In the above result, setting up Prometheus returned ‘success’: False, ‘msg’: ‘Prometheus playbook install failed’ This means that Grafana, which is part of the Promtheus install was most likely not installed.The ssh tunnel to trying to connect to Grafana’s port is unable to connect since there is no Grafana running, thus the channel 3: open failed: connect failed: Connection refused error.The error was caused by an ansible related update which broke the installation process. We have found the problem and will be pushing out a fix today.The MeasurementFramework has been updated to fix the docker conflict.
Prometheus system is now working. There is an error in a script due to a mirror problem, but this does not affect the Prometheus install.The ELK install has a fatal mirror problem that remains to be fixed. I will post here when that is completed.
