# Set the command-line arguments to pass to the server.
# QUERY_PORT: Listen port for the HTTP API and web UI; Defaults to 9411
# QUERY_ENABLED: false disables the HTTP read endpoints under '/api/v2'. This also disables the UI, as it relies on the API. If your only goal is to restrict search, use SEARCH_ENABLED instead. Defaults to true
# SEARCH_ENABLED: false disables searching in the query API and any indexing or post-processing in the collector to support search. This does not disable the entire UI, as trace by ID and dependency queries still operate. Disable this when you use another service (such as logs) to find trace IDs. Defaults to true
# QUERY_TIMEOUT: Sets the hard timeout for query requests. Accepts any duration string (e.g., 100ms). A value of 0 will disable the timeout completely. Defaults to 11s.
# QUERY_LOG_LEVEL: Log level written to the console; Defaults to INFO
# QUERY_NAMES_MAX_AGE: Controls the value of the max-age header zipkin-server responds with on http requests for autocompleted values in the UI (service names for example). Defaults to 300 seconds.
# QUERY_LOOKBACK: How many milliseconds queries can look back from endTs; Defaults to 24 hours (two daily buckets: one for today and one for yesterday)
# STORAGE_TYPE: SpanStore implementation: one of mem, mysql, cassandra, elasticsearch
# COLLECTOR_SAMPLE_RATE: Percentage of traces to retain, defaults to always sample (1.0).
# AUTOCOMPLETE_KEYS: list of span tag keys which will be returned by the /api/v2/autocompleteTags endpoint; Tag keys should be comma separated e.g. "instance_id,user_id,env"
# AUTOCOMPLETE_TTL: How long in milliseconds to suppress calls to write the same autocomplete key/value pair. Default 3600000 (1 hr)
