Φορτίο 1.3.0 usage:
        fortio command [flags] target
where command is one of: load (load testing), server (starts grpc ping and
http echo/ui/redirect/proxy servers), grpcping (grpc client), report (report
only UI server), redirect (redirect only server), or curl (single URL debug).
where target is a url (http load tests) or host:port (grpc health test).
flags are:
  -H header
        Additional header(s)
  -L    Follow redirects (implies -std-client) - do not use for load test
  -P value
        Proxies to run, e.g -P "localport1 dest_host1:dest_port1" -P "[::1]:0
www.google.com:443" ...
  -a    Automatically save JSON result with filename based on labels & timestamp
  -abort-on int
        Http code that if encountered aborts the run. e.g. 503 or -1 for socket
errors.
  -allow-initial-errors
        Allow and don't abort on initial warmup errors
  -base-url string
        base URL used as prefix for data/index.tsv generation. (when empty, the

  -c int
        Number of connections/goroutine/threads (default 4)
  -cacert Path
        Path to a custom CA certificate file to be used for the GRPC client
TLS, if empty, use https:// prefix for standard internet CAs TLS

        Path to the certificate file to be used for GRPC server TLS
  -compression
        Enable http compression
  -content-type string
        Sets http content type. Setting this value switches the request method
from GET to POST.
  -curl
        Just fetch the content once
  -data-dir Directory
        Directory where JSON results are stored/read (default ".")
  -echo-debug-path string
        http echo server URI for debug, empty turns off that part (more secure)
(default "/debug")
  -gomaxprocs int
        Setting for runtime.GOMAXPROCS, <1 doesn't change the default
  -grpc
        Use GRPC (health check by default, add -ping for ping) for load testing
  -grpc-max-streams uint
        MaxConcurrentStreams for the grpc server. Default (0) is to leave the
option unset.
  -grpc-ping-delay duration
        grpc ping delay in response
  -grpc-port string
        grpc server port. Can be in the form of host:port, ip:port or port or
/unix/domain/path or "disabled" to not start the grpc server. (default "8079")
  -halfclose
        When not keepalive, whether to half close the connection (only for fast
http)
  -health
        grpc ping client mode: use health instead of ping
  -healthservice string
        which service string to pass to health check
  -http-port string
        http echo server port. Can be in the form of host:port, ip:port, port
or /unix/domain/path. (default "8080")
  -http1.0
        Use http1.0 (instead of http 1.1)
  -httpbufferkb kbytes
        Size of the buffer (max data size) for the optimized http client in
kbytes (default 128)
  -httpccch
        Check for Connection: Close Header
  -https-insecure
        Long form of the -k flag
  -json path
        Json output to provided file path or '-' for stdout (empty = no json
output, unless -a is used)
  -k    Do not verify certs in https connections
  -keepalive
        Keep connection alive (only for fast http 1.1) (default true)
  -key Path
        Path to the key file used for GRPC server TLS
  -labels string
        Additional config data/labels to add to the resulting JSON, defaults to
target URL and hostname
  -logcaller

        Prefix to log lines before logged messages (default "> ")
  -maxpayloadsizekb int
        MaxPayloadSize is the maximum size of payload to be generated by the
EchoHandler size= argument. In Kbytes. (default 256)
  -n int
        Run for exactly this number of calls instead of duration. Default (0)
is to use duration (-t). Default is 1 when used as grpc ping count.
  -p string
        List of pXX to calculate (default "50,75,90,99,99.9")
  -payload string
        Payload string to send along
  -payload-file path
        File path to be use as payload (POST for http), replaces -payload when
set.
  -payload-size int
        Additional random payload size, replaces -payload when set > 0, must be
smaller than -maxpayloadsizekb. Setting this switches http to POST.
  -ping
        grpc load test: use ping instead of health
  -profile file
        write .cpu and .mem profiles to file
  -qps float
        Queries Per Seconds or 0 for no wait/max qps (default 8)
  -quiet

        How long to run the test or 0 to run until ^C (default 5s)
  -timeout duration
        Connection and read timeout value (for http) (default 15s)
  -ui-path string
        http server URI for UI, empty turns off that part (more secure)
