connqc is a tool to control the quality of the network transport between multiple regions.
It consists of a server that listens for TCP probing messages, and a client that sends said messages.
The client logs the probing duration and warns if some messages get lost.
Start the server. The default address is :8123:
$ connqc server or specify a port:
$ connqc server --addr=":1234"The server command supports the following additional arguments.
OPTIONS:
--addr value The address to listen on for probe messages (default: ":8123") [$ADDR]
--buffer-size value The size of the read buffer used by the server (default: 512) [$BUFFER_SIZE]
--read-timeout value The duration after which the server should timeout when reading from a connection (default: 2s) [$READ_TIMEOUT]
--write-timeout value The duration after which the server should timeout when writing to a connection (default: 5s) [$WRITE_TIMEOUT]
--log.format value Specify the format of logs. Supported formats: 'logfmt', 'json', 'console' [$LOG_FORMAT]
--log.level value Specify the log level. e.g. 'debug', 'info', 'error'. (default: "info") [$LOG_LEVEL]
--log.ctx value [ --log.ctx value ] A list of context field appended to every log. Format: key=value. [$LOG_CTX]
--help, -h show helpFor use on firewalls managed with firewall-cmd:
$ firewall-cmd --add-port=8123/tcp
# and later after the test is done
$ firewall-cmd --remove-port=8123/tcpStart the client with the connqc server's address:
$ connqc client --addr="127.0.0.1:8123"To enable more human-readable logs, set the log format:
$ connqc client --addr="127.0.0.1:8123" --log.format="console"To increase the amount of sent requests, reduce the interval:
$ connqc client --addr="127.0.0.1:8123" --interval="200ms"The client command supports the following additional arguments.
OPTIONS:
--protocol value Use protocol for the connection (available: tcp, udp) (default: "tcp") [$PROTOCOL]
--addr value The address of the connqc server [$ADDR]
--backoff value The duration to wait for before retrying to connect to the server (default: 1s) [$BACKOFF]
--interval value The interval at which to send probe messages to the server (default: 1s) [$INTERVAL]
--read-timeout value The duration after which the client should timeout when reading from a connection (default: 2s) [$READ_TIMEOUT]
--write-timeout value The duration after which the client should timeout when writing to a connection (default: 5s) [$WRITE_TIMEOUT]
--log.format value Specify the format of logs. Supported formats: 'logfmt', 'json', 'console' [$LOG_FORMAT]
--log.level value Specify the log level. e.g. 'debug', 'info', 'error'. (default: "info") [$LOG_LEVEL]
--log.ctx value [ --log.ctx value ] A list of context field appended to every log. Format: key=value. [$LOG_CTX]
