usage: ghz [<flags>] [<host>] Flags: -h, --help Show context-sensitive help (also try --help-long and --help-man). --config= Path to the JSON or TOML config file that specifies all the test run settings. --proto= The Protocol Buffer .proto file. --protoset= The compiled protoset file. Alternative to proto. -proto takes precedence. --call= A fully-qualified method name in 'package.Service/method' or 'package.Service.Method' format. -i, --import-paths= Comma separated list of proto import paths. The current working directory and the directory of the protocol buffer file are automatically added to the import list. --cacert= File containing trusted root certificates for verifying the server. --cert= File containing client certificate (public key), to present to the server. Must also provide -key option. --key= File containing client private key, to present to the server. Must also provide -cert option. --cname= Server name override when validating TLS certificate - useful for self signed certs. --skipTLS Skip TLS client verification of the server's certificate chain and host name. --insecure Use plaintext and insecure connection. --authority= Value to be used as the :authority pseudo-header. Only works if -insecure is used. --async Make requests asynchronous as soon as possible. Does not wait for request to finish before sending next one. -r, --rps=0 Requests per second (RPS) rate limit for constant load schedule. Default is no rate limit. --load-schedule="const" Specifies the load schedule. Options are const, step, or line. Default is const. --load-start=0 Specifies the RPS load start value for step or line schedules. --load-step=0 Specifies the load step value or slope value. --load-end=0 Specifies the load end value for step or line load schedules. --load-step-duration=0 Specifies the load step duration value for step load schedule. --load-max-duration=0 Specifies the max load duration value for step or line load schedule. -c, --concurrency=50 Number of request workers to run concurrently for const concurrency schedule. Default is 50. --concurrency-schedule="const" Concurrency change schedule. Options are const, step, or line. Default is const. --concurrency-start=0 Concurrency start value for step and line concurrency schedules. --concurrency-end=0 Concurrency end value for step and line concurrency schedules. --concurrency-step=1 Concurrency step / slope value for step and line concurrency schedules. --concurrency-step-duration=0 Specifies the concurrency step duration value for step concurrency schedule. --concurrency-max-duration=0 Specifies the max concurrency adjustment duration value for step or line concurrency schedule. -n, --total=200 Number of requests to run. Default is 200. -t, --timeout=20s Timeout for each request. Default is 20s, use 0 for infinite. -z, --duration=0 Duration of application to send requests. When duration is reached, application stops and exits. If duration is specified, n is ignored. Examples: -z 10s -z 3m. -x, --max-duration=0 Maximum duration of application to send requests with n setting respected. If duration is reached before n requests are completed, application stops and exits. Examples: -x 10s -x 3m. --duration-stop="close" Specifies how duration stop is reported. Options are close, wait or ignore. Default is close. -d, --data= The call data as stringified JSON. If the value is '@' then the request contents are read from stdin. -D, --data-file= File path for call data JSON file. Examples: /home/user/file.json or ./file.json. -b, --binary The call data comes as serialized binary message or multiple count-prefixed messages read from stdin. -B, --binary-file= File path for the call data as serialized binary message or multiple count-prefixed messages. -m, --metadata= Request metadata as stringified JSON. -M, --metadata-file= File path for call metadata JSON file. Examples: /home/user/metadata.json or ./metadata.json. --stream-interval=0 Interval for stream requests between message sends. --stream-call-duration=0 Duration after which client will close the stream in each streaming call. --stream-call-count=0 Count of messages sent, after which client will close the stream in each streaming call. --stream-dynamic-messages In streaming calls, regenerate and apply call template data on every message send. --reflect-metadata= Reflect metadata as stringified JSON used only for reflection request. -o, --output= Output path. If none provided stdout is used. -O, --format= Output format. One of: summary, csv, json, pretty, html, influx-summary, influx-details. Default is summary. --skipFirst=0 Skip the first X requests when doing the results tally. --count-errors Count erroneous (non-OK) resoponses in stats calculations. --connections=1 Number of connections to use. Concurrency is distributed evenly among all the connections. Default is 1. --connect-timeout=10s Connection timeout for the initial connection dial. Default is 10s. --keepalive=0 Keepalive time duration. Only used if present and above 0. --name= User specified name for the test. --tags= JSON representation of user-defined string tags. --cpus=12 Number of cpu cores to use. --debug= The path to debug log file. -e, --enable-compression Enable Gzip compression on requests. -v, --version Show application version. Args: [<host>] Host and port to test.
