+## Parametrizing the log output level
+
+The relayer configuration file, called `loop_config.toml` in the examples above
+permits parametrization of output verbosity via the knob called `log_level`.
+Relevant snippet: 
+
+```toml
+[global]
+timeout = '10s'
+strategy = 'naive'
+log_level = 'error'
+```
+
+Valid options for `log_level` are: 'error', 'warn', 'info', 'debug', 'trace'.
+These levels correspond to the tracing sub-component of the relayer-cli, [see 
+here](https://docs.rs/tracing-core/0.1.17/tracing_core/struct.Level.html).
+
+The relayer will _always_ print a last line summarizing the result of its 
+operation for queries of transactions. In addition to  this last line, 
+arbitrary debug, info, or other outputs may be produced.  Example, with 
+`log_level = 'debug'`:
+
+```bash
+Running `target/debug/relayer -c loop_config.toml query client consensus ibc-0 07-tendermint-X 0 1`
+{"timestamp":"Jan 20 19:21:52.070","level":"DEBUG","fields":{"message":"registered component: abscissa_core::terminal::component::Terminal (v0.5.2)"},"target":"abscissa_core::component::registry"}
+{"timestamp":"Jan 20 19:21:52.071","level":"DEBUG","fields":{"message":"registered component: relayer_cli::components::Tracing (v0.0.6)"},"target":"abscissa_core::component::registry"}
+{"timestamp":"Jan 20 19:21:52.078","level":"INFO","fields":{"message":"Options QueryClientConsensusOptions { client_id: ClientId(\"07-tendermint-X\"), revision_number: 0, revision_height: 1, height: 0, proof: true }"},"target":"relayer_cli::commands::query::client"}
+{"timestamp":"Jan 20 19:21:52.080","level":"DEBUG","fields":{"message":"resolving host=\"localhost\""},"target":"hyper::client::connect::dns"}
+{"timestamp":"Jan 20 19:21:52.083","level":"DEBUG","fields":{"message":"connecting to [::1]:26657"},"target":"hyper::client::connect::http"}
+{"timestamp":"Jan 20 19:21:52.083","level":"DEBUG","fields":{"message":"connecting to 127.0.0.1:26657"},"target":"hyper::client::connect::http"}
+{"status":"error","result":["query error: RPC error to endpoint tcp://localhost:26657: error trying to connect: tcp connect error: Connection refused (os error 61) (code: 0)"]}
+```
+
+For the same command, with `log_level = 'error'`, just the last line will be 
+produced:
+
+```bash
+   Running `target/debug/relayer -c loop_config.toml query client consensus ibc-0 07-tendermint-X 0 1`
+{"status":"error","result":["query error: RPC error to endpoint tcp://localhost:26657: error trying to connect: tcp connect error: Connection refused (os error 61) (code: 0)"]}
+```
