Usage of /usr/bin/demo: --alsologtostderr log to standard error as well as files --bind-address string Bind address for the server. If empty, the server will listen on all available unicast and anycast IP addresses of the local system. --catch-sigpipe catch and ignore SIGPIPE on stdout and stderr if specified --config-file string Full path of the config file (with extension) to use. If set, --config-path, --config-type, and --config-name are ignored. --config-file-not-found-handling ConfigFileNotFoundHandling Behavior when a config file is not found. (Options: error, exit, ignore, warn) (default warn) --config-name string Name of the config file (without extension) to search for. (default "vtconfig") --config-path strings Paths to search for config files in. (default [/tmp]) --config-persistence-min-interval duration minimum interval between persisting dynamic config changes back to disk (if no change has occurred, nothing is done). (default 1s) --config-type string Config file type (omit to infer config type from file extension). --duration duration total duration the demo runs (default 10m0s) --grpc-auth-mode string Which auth plugin implementation to use (eg: static) --grpc-auth-mtls-allowed-substrings string List of substrings of at least one of the client certificate names (separated by colon). --grpc-auth-static-password-file string JSON File to read the users/passwords from. --grpc-bind-address string Bind address for gRPC calls. If empty, listen on all addresses. --grpc-ca string server CA to use for gRPC connections, requires TLS, and enforces client certificate check --grpc-cert string server certificate to use for gRPC connections, requires grpc-key, enables TLS --grpc-crl string path to a certificate revocation list in PEM format, client certificates will be further verified against this file during TLS handshake --grpc-enable-optional-tls enable optional TLS mode when a server accepts both TLS and plain-text connections on the same port; plain-text connections are served unauthenticated, even with --grpc-ca --grpc-enable-orca-metrics gRPC server option to enable sending ORCA metrics to clients for load balancing --grpc-key string server private key to use for gRPC connections, requires grpc-cert, enables TLS --grpc-max-connection-age duration Maximum age of a client connection before GoAway is sent. (default 2562047h47m16.854775807s) --grpc-max-connection-age-grace duration Additional grace period after grpc-max-connection-age, after which connections are forcibly closed. (default 2562047h47m16.854775807s) --grpc-port int Port to listen on for gRPC calls. If zero, do not listen. --grpc-server-ca string path to server CA in PEM format, which will be combine with server cert, return full certificate chain to clients --grpc-server-initial-conn-window-size int gRPC server initial connection window size --grpc-server-initial-window-size int gRPC server initial window size --grpc-server-keepalive-enforcement-policy-min-time duration gRPC server minimum keepalive time (default 10s) --grpc-server-keepalive-enforcement-policy-permit-without-stream gRPC server permit client keepalive pings even when there are no active streams (RPCs) --grpc-server-keepalive-time duration After a duration of this time, if the server doesn't see any activity, it pings the client to see if the transport is still alive. (default 10s) --grpc-server-keepalive-timeout duration After having pinged for keepalive check, the server waits for a duration of Timeout and if no activity is seen even after that the connection is closed. (default 10s) -h, --help display usage and exit --keep-logs duration keep logs for this long (using ctime) (zero to keep forever) --keep-logs-by-mtime duration keep logs for this long (using mtime) (zero to keep forever) --lag_update_interval duration interval at which the current replication lag will be broadcast to the throttler (default 5s) --lameduck-period duration keep running at least this long after SIGTERM before stopping (default 50ms) --log-err-stacks log stack traces for errors --log-format string log output format: json for machine-readable JSON, text for human-readable colored output (default "json") --log-level string minimum log level when structured logging is enabled (debug, info, warn, error) (default "info") --log-rotate-max-size uint size in bytes at which logs are rotated (glog.MaxSize) (default 1887436800) --log-structured enable structured JSON logging (default true) --log_backtrace_at traceLocations when logging hits line file:N, emit a stack trace --log_dir string If non-empty, write log files in this directory --log_link string If non-empty, add symbolic links in this directory to the log files --logbuflevel int Buffer log messages logged at this level or lower (-1 means don't buffer; 0 means buffer INFO only; ...). Has limited applicability on non-prod platforms. --logtostderr log to standard error instead of files --max-stack-size int configure the maximum stack size in bytes (default 67108864) --onclose-timeout duration wait no more than this for OnClose handlers before stopping (default 10s) --onterm-timeout duration wait no more than this for OnTermSync handlers before stopping (default 10s) --pid-file string If set, the process will write its pid to the named file, and delete it on graceful shutdown. --port int port for the server --pprof strings enable profiling --pprof-http enable pprof http endpoints --purge-logs-interval duration how often try to remove old logs (default 1h0m0s) --rate int maximum rate of the throttled demo server at the start (default 1000) --replica_degration_duration duration duration a simulated degration should take (default 10s) --replica_degration_interval duration simulate a throughput degration of the replica every X interval (i.e. the replica applies transactions at a slower rate for -reparent_duration and the replication lag might go up) --stderrthreshold severityFlag logs at or above this threshold go to stderr (default 1) --table-refresh-interval int interval in milliseconds to refresh tables in status page with refreshRequired class --v Level log level for V logs -v, --version print binary version --vmodule vModuleFlag comma-separated list of pattern=N settings for file-filtered logging
