Benchmarking and Monitoring
===========================
tm-bench
--------
Tendermint blockchain benchmarking tool: https://github.com/tendermint/tools/tree/master/tm-bench
For example, the following:
::
tm-bench -T 10 -r 1000 localhost:46657
will output:
::
Stats Avg Stdev Max
Block latency 6.18ms 3.19ms 14ms
Blocks/sec 0.828 0.378 1
Txs/sec 963 493 1811
Quick Start
^^^^^^^^^^^
Docker
~~~~~~
::
docker run -it --rm -v "/tmp:/tendermint" tendermint/tendermint:0.12.1 init
docker run -it --rm -v "/tmp:/tendermint" -p "46657:46657" --name=tm tendermint/tendermint:0.12.1
docker run -it --rm --link=tm tendermint/bench tm:46657
Binaries
~~~~~~~~
If **Linux**, start with:
::
curl -L https://s3-us-west-2.amazonaws.com/tendermint/0.12.1/tendermint_linux_amd64.zip && sudo unzip -d /usr/local/bin tendermint_linux_amd64.zip && sudo chmod +x tendermint
if **Mac OS**, start with:
::
curl -L https://s3-us-west-2.amazonaws.com/tendermint/0.12.1/tendermint_darwin_amd64.zip && sudo unzip -d /usr/local/bin tendermint_darwin_amd64.zip && sudo chmod +x tendermint
then run:
::
tendermint init
tendermint node --app_proxy=dummy
tm-bench localhost:46657
with the last command being in a seperate window.
Usage
^^^^^
::
tm-bench [-c 1] [-T 10] [-r 1000] [endpoints]
Examples:
tm-bench localhost:46657
Flags:
-T int
Exit after the specified amount of time in seconds (default 10)
-c int
Connections to keep open per endpoint (default 1)
-r int
Txs per second to send in a connection (default 1000)
-v Verbose output
Development
^^^^^^^^^^^
::
make get_vendor_deps
make test
tm-monitor
----------
Tendermint blockchain monitoring tool; watches over one or more nodes, collecting and providing various statistics to the user: https://github.com/tendermint/tools/tree/master/tm-monitor
Quick Start
^^^^^^^^^^^
Docker
~~~~~~
::
docker run -it --rm -v "/tmp:/tendermint" tendermint/tendermint init
docker run -it --rm -v "/tmp:/tendermint" -p "46657:46657" --name=tm tendermint/tendermint
docker run -it --rm --link=tm tendermint/monitor tm:46657
Binaries

This will be the same as you did for ``tm-bench`` above, except for the last line which should be:
::
tm-monitor localhost:46657
Usage
^^^^^
::
tm-monitor [-v] [-no-ton] [-listen-addr="tcp://0.0.0.0:46670"] [endpoints]
Examples:
# monitor single instance
tm-monitor localhost:46657
# monitor a few instances by providing comma-separated list of RPC endpoints
tm-monitor host1:46657,host2:46657
Flags:
-listen-addr string
HTTP and Websocket server listen address (default "tcp://0.0.0.0:46670")
-no-ton
Do not show ton (table of nodes)
-v verbose logging
RPC UI
^^^^^^
Run ``tm-monitor`` and visit http://localhost:46670
You should see the list of the available RPC endpoints:
::
http://localhost:46670/status
http://localhost:46670/status/network
http://localhost:46670/monitor?endpoint=_
http://localhost:46670/status/node?name=_
http://localhost:46670/unmonitor?endpoint=_
The API is available as GET requests with URI encoded parameters, or as JSONRPC
POST requests. The JSONRPC methods are also exposed over websocket.
Development
^^^^^^^^^^^
::
make get_vendor_deps
make test
