How can override the TDMS Logger in Veristand

[RGSchmidt]

I have never liked TDMS log format or Diadem; since I have no waveforms only distinct voltages and CANbus messages where I just need timestamp / state, I would like to route to a remote file via TCP or even http as well as locally. This would be similar to how you can write log files in a custom format use Python logging facility, log4j or even log4go. It also gives me the ability to view via a web service that displays the incoming from anywhere.

I am using Python to execute the Veristand tests and would like to have a consistent log file and format for the script execution and the output on the Veristand engine.

I would rather not have to convert the TDMS file after the test completes to write to the ELK (Elasticsearch Logstash and Kibana) stack for analysis and display from a web GUI using Grafana/Kibana.

Is this possible? Can I modify the Veristand Gateway to send messages to the host PC so I can log the data?

See Data Logging Options for the built-in logging options. There are a few options which save the file on the host PC.

Alternatively, you can use the UDP Streaming API to read from the VeriStand Gateway. There is a shipping example for that.

Not what I am looking for unless I am misunderstanding what I am reading. I do not want to use any logging within Veristand to TDMS format, do post-processing on the file, save the file on the host, or upload the file when done. UDP will not work as no guarantee that I will capture all messages.

I literally want to disable the TDMS and install a different logger to be used within Veristand that will connect to a remote logging application using http and either stores data in database locally or uploads it to Elasticsearch. Nothing I have seen in the documentation says that this can be done.

Thanks

You can stream from VeriStand to a Labview VI via UDP using the VeriStand APIs.  When streaming over UDP you can then read in the waveforms and convert them to whatever format you need.

Not using LabVIEW ... Using Python to launch Veristand and run scripts. Don't need or want any waveforms and UDP is not a good solution since delivery is not guaranteed and I am not trying to collect data on the host PC but another PC running Linux.

Thanks.
