Troubleshooting

This document will help you troubleshoot common issues with your Fluvio cluster.

Troubleshooting a Local Cluster

To troubleshoot a local Fluvio cluster, you can check the logs of the SC and SPUs processes.

  • Run cat ~/.fluvio/log/flv_sc.log for SC logs
  • Run cat ~/.fluvio/log/spu_log_XXXX.log for each SPU
    • E.g. when running 1 SPU, there will be spu_log_5001.log

You can also use tail -n 100 ~/.fluvio/log/flv_sc.log to just print the last 100 lines of the log file.

Log directory

By default, Fluvio logs are stored in the ~/.fluvio/log directory. But if you have the FLUVIO_DIR environment variable set, the logs will be stored in the directory specified by the variable.

Setting log level

You can set various log levels as filering tracing log.

For example, to start cluster using log level info using cluster start

$ fluvio cluster start --rust-log=info

For individual binaries, you can use RUST_LOG env variable:

$ RUST_LOG=info fluvio run sc --local

The log level can be set to trace, debug, info, warn, error.
