# Action Injector

Action injector is a simulation tool to simulate action traffic by injecting random actions to the gateway node.

inject actions [options : -m] (default:random).

Usage:
  injector inject [flags]

Flags:
      --action-type string            action type to inject (default "transfer")
      --addr string                   target ip:port for grpc connection (default "127.0.0.1:14014")
      --aps int                       actions to be injected per second (default 30)
      --check-recipt                  check recept
      --contract string               smart contract address (default "io1pmjhyksxmz2xpxn2qmz4gx9qq2kn2gdr8un4xq")
      --duration duration             duration when the injection will run (default 60h0m0s)
      --execution-amount int          execution amount
      --execution-gas-limit uint      execution gas limit (default 100000)
      --execution-gas-price int       execution gas price
  -h, --help                          help for inject
      --injector-config-path string   path of config file of genesis transfer addresses (default "./tools/actioninjector.v2/gentsfaddrs.yaml")
      --insecure                      insecure network
      --load-token-amount int         init load how much token to inject accounts
      --rand-accounts int             number of accounst to use (default 3000)
      --reset-interval duration       time interval to reset nonce counter (default 10s)
      --retry-interval duration       sleep interval between two consecutive rpc retries (default 1s)
      --retry-num uint                maximum number of rpc retries (default 5)
      --transfer-amount int           execution amount
      --transfer-gas-limit uint       transfer gas limit (default 20000)
      --transfer-gas-price int        transfer gas price
      --workers uint                  number of workers (default 10)

Note that is you encounter issues such as "action is not found", check for following reasons:

  1. incorrect nonce (too small or too large)
  2. too low gas price
  3. too small gas limit
  4. account balance insufficient (amount + gas price * gas limit)
