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. -c, --concurrency=50 Number of requests to run concurrently. Total number of requests cannot be smaller than the concurrency level. Default is 50. -n, --total=200 Number of requests to run. Default is 200. -q, --qps=0 Rate limit, in queries per second (QPS). Default is no rate limit. -t, --timeout=20 Timeout for each request in seconds. Default is 20, 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. --connections=1 Number of connections to use. Concurrency is distributed evenly among all the connections. Default is 1. -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. --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. --connect-timeout=10 Connection timeout in seconds for the initial connection dial. Default is 10. --keepalive=0 Keepalive time in seconds. Only used if present and above 0. --name= User specified name for the test. --tags= JSON representation of user-defined string tags. --cpus=8 Number of cpu cores to use. -v, --version Show application version. Args: [<host>] Host and port to test.
