Oxen Tree

You can use oxen tree to view the current state of the merkle tree for a commit. This gives you a view of the metadata contained in the tree for each file and directory, as well as how many VNodes are present.

Oxen Node

oxen node can be used to inspect file and dir nodes in the merkle tree. This can be used to check whether nodes exist and have been created properly in the merkle tree. You can search for a node by hash or by path.

​
Concurrency

By default, oxen will use up to 8 threads for its parallelized operations (oxen add, oxen push, etc.). This can be configured via the OXEN_NUM_THREADS environment variable. If OXEN_NUM_THREADS is set, oxen will instead use that many threads, so long as they are available on the local machine. 
export OXEN_NUM_THREADS="16"

​
HTTP Requests

When uploading or downloading data, if any files fail to transfer, oxen will wait and retry the request. By default, oxen will allow up to 10 retries before cancelling the operation. This can be configured via the enviornment variable NUM_HTTP_REQUESTS 
export NUM_HTTP_RETRIES="10"
All HTTP requests oxen makes timeout after 120 seconds by default. You can configure this the OXEN_TIMEOUT_SECS variable. 
export OXEN_TIMEOUT_SECS="10"

​
Chunk Size

Under the hood, oxen groups files into small files and large files for more efficient transfer in oxen push, oxen workspace add, etc. Files are considered large if they’re larger than AVG_CHUNK_SIZE, which is set to 10 MB by default. This can be configured via the AVG_CHUNK_SIZE environment variable 
export AVG_CHUNK_SIZE="20_000_000"

​
Debug Logs

The oxen codebase contains plenty of debug logs, which you can turn on with the RUST_LOG variable. 
export RUST_LOG="debug"
You can also set RUST_LOG to info or warn for more restrictive debug logs
