mtstress [flags] <command>
The mtstress commands are:
mount Measure latency of the Mount RPC at a fixed request rate resolve Measure latency of the Resolve RPC at a fixed request rate help Display help for commands or topics
The global flags are:
-duration=10s Duration for sending test traffic and measuring latency -rate=1 Rate, in RPCs per second, to send to the test server -reauthenticate=false If true, establish a new authenticated connection for each RPC, simulating load from a distinct process -alsologtostderr=true log to standard error as well as files -log_backtrace_at=:0 when logging hits line file:N, emit a stack trace -log_dir= if non-empty, write log files to this directory -logtostderr=false log to standard error instead of files -max_stack_buf_size=4292608 max size in bytes of the buffer to use for logging stack traces -metadata=<just specify -metadata to activate> Displays metadata for the program and exits. -stderrthreshold=2 logs at or above this threshold go to stderr -time=false Dump timing information to stderr before exiting the program. -v=0 log level for V logs -v23.credentials= directory to use for storing security credentials -v23.i18n-catalogue= 18n catalogue files to load, comma separated -v23.namespace.root=[/(dev.v.io:role:vprod:service:mounttabled)@ns.dev.v.io:8101] local namespace root; can be repeated to provided multiple roots -v23.proxy= object name of proxy service to use to export services across network boundaries -v23.tcp.address= address to listen on -v23.tcp.protocol=wsh protocol to listen with -v23.vtrace.cache-size=1024 The number of vtrace traces to store in memory. -v23.vtrace.collect-regexp= Spans and annotations that match this regular expression will trigger trace collection. -v23.vtrace.dump-on-shutdown=true If true, dump all stored traces on runtime shutdown. -v23.vtrace.sample-rate=0 Rate (from 0.0 to 1.0) to sample vtrace traces. -v23.vtrace.v=0 The verbosity level of the log messages to be captured in traces -vmodule= comma-separated list of globpattern=N settings for filename-filtered logging (without the .go suffix). E.g. foo/bar/baz.go is matched by patterns baz or *az or b* but not by bar/baz or baz.go or az or b.* -vpath= comma-separated list of regexppattern=N settings for file pathname-filtered logging (without the .go suffix). E.g. foo/bar/baz.go is matched by patterns foo/bar/baz or fo.*az or oo/ba or b.z but not by foo/bar/baz.go or fo*az
Mtstress mount - Measure latency of the Mount RPC at a fixed request rate ¶
Repeatedly issues a Mount request (at --rate) and measures latency ¶
mtstress mount [flags] <mountpoint> <ttl>
<mountpoint> defines the name to be mounted
<ttl> specfies the time-to-live of the mount point. For example: 5s for 5 seconds, 1m for 1 minute etc. Valid time units are "ms", "s", "m", "h".
Mtstress resolve - Measure latency of the Resolve RPC at a fixed request rate ¶
Repeatedly issues a Resolve request (at --rate) to a name and measures latency ¶
mtstress resolve [flags] <name>
<name> the object name to resolve
Mtstress help - Display help for commands or topics ¶
Help with no args displays the usage of the parent command.
Help with args displays the usage of the specified sub-command or help topic.
"help ..." recursively displays help for all commands and topics.
mtstress help [flags] [command/topic ...]
[command/topic ...] optionally identifies a specific sub-command or help topic.
The mtstress help flags are:
-style=compact The formatting style for help output: compact - Good for compact cmdline output. full - Good for cmdline output, shows all global flags. godoc - Good for godoc processing. shortonly - Only output short description. Override the default by setting the CMDLINE_STYLE environment variable. -width=<terminal width> Format output to this target width in runes, or unlimited if width < 0. Defaults to the terminal width if available. Override the default by setting the CMDLINE_WIDTH environment variable.
