You can always check by running it with following flags, which forces a dry-run (without sending anything to the server).
--url "" --verbosity 2
Every report contains basic details: poll_interval, allowed_entropy, allow_private_channels, chain, network and pubkey.
Besides it can contain node_details in a JSON format similar to lnd getnodeinfoi.
Additional fields are node_version, is_synced_to_chain and is_synced_to_graph, onchain_balance_total and onchain_balance_total. Node details will be reported just first time and if anything changes later on (during periodic polling).
Using --noonchainbalance it is possible to disable reporting on-chain balance.

Actual channel balance is reported through changed_channels and if any channels closings were detected that is sent via closed_channels:

poll_interval is the setting how often to poll for changes and allowed_entropy is the entropy in bits that you can also specify via --allowedentropy flag.
local_nominator / denominator is the fraction of how much balance is on your side and remote_nominator / denominator is on the other side of the channel.
If you use a high enough entropy denominator is same as capacity in satoshis and thus the nominator values can then be interpreted as balance on each side.
Note that local + remote balance is not necessary equal to capacity due to channel reserve and other factors.
