Environment / auth

SYMBOL_NODE_URL
required
REST URL of the Symbol node to query, e.g. https://<node-host>:3001; https:// is required (http:// only for localhost / 127.0.0.1 / [::1]) and the port is used exactly as given.
SYMBOL_NETWORK
mainnet or testnet; when set, start-up fails if the node reports a different network.
SYMBOL_TIMEZONE
IANA zone such as Asia/Tokyo that adds a local time next to every UTC timestamp.
SYMBOL_REFERENCE_NODES
Comma-separated https:// node URLs that symbol_network_compare and symbol_version_drift check against; no other host is ever contacted.
SYMBOL_REQUEST_TIMEOUT_MS
Per-request timeout in milliseconds, 100 to 600000 (default 10000).
SYMBOL_STATE_DIR
Absolute directory where symbol_harvester_watch keeps one snapshot file per node (unlocked harvester public keys, heights and times; no secrets), created on first save with mode 0700; when unset, the tool reports the current list without a comparison.
