Quickstart

|
|
|
Steth is an inspection tool that can aid in pinpointing issues before deployment
|
|
and during operation of an OpenStack environment.
|
|
|
|
It is modelled as agent(s)/client in which a controller interacts with
|
|
agents deployed in your environment. Let me introduce how to use steth.
|
|
|
|
|
|
-------------
|
|
Download code
|
|
-------------
|
|
|
|
Download the latest code from git repository. And run
|
|
``python setup.py install`` to install steth. After running that, you can
|
|
``steth --help`` to confirm Steth is installed correctly.
|
|
|
|
-------------
|
|
Before Deploy
|
|
-------------
|
|
|
|
Before deploy Steth Agent and Steth Client, you should make sure you have
|
|
installed all dependencies to run Steth. If you plan to deploy Steth on Ubuntu,
|
|
you should install `python-dev` and `libpcap-dev` in your machine before you
|
|
run ``pip install -r requirements.txt``.
|
|
|
|
------------------
|
|
Deploy Steth Agent
|
|
------------------
|
|
|
|
Steth Agent listens in 0.0.0.0:9698 on any node you want. It will wait for
|
|
RPC request. Currently we support CentOS 6.5, CentOS 7.0 and CentOS 7.1 only.
|
|
In CentOS 6.5, you should run ``service steth-agent start`` to start
|
|
steth-agent. In CentOS 7.0 and 7.1, you should run ``systemctl start steth``
|
|
to start steth-agent.
|
|
|
|
|
|
-------------------
|
|
Deploy Steth Client
|
|
-------------------
|
|
|
|
Steth Client is a stateless program. You can run ``steth --help`` to show all
|
|
steth commands that you can run.
|
|
|
|
|
|
------------------
|
|
Configuration File
|
|
------------------
|
|
|
|
On start the client will read a configuration file. By default the configuration
|
|
file is located at ``/etc/steth/steth.conf``.
|
|
|
|
Here is an example of the configuration file
|
|
|
|
::
|
|
|
|
[DEFAULT]
|
|
# (ListOpt) list of networks types.
|
|
# We may have multi network types in one node, such as mgmt, net and stroage.
|
|
# so this value should be a list.
|
|
# We seperate each item by ":". Treat first item as network type.
|
|
# The second is physical nic name. And the third is network_prefix.
|
|
# Example: "mgmt:eth0:1.1.1.,net:eth1:2.2.2.,storage:eth2:3.3.3."
|
|
network_types=mgmt:eth0:1.1.1.,net:eth1:2.2.2.,storage:eth2:3.3.3.
|
|
|
|
# (ListOpt) All nodes info. Just need sequence number.
|
|
# Example: 64, 65, 66
|
|
nodes_id=39,233,64,65,66
|
|
|
|
# (StrOpt) Name prefix of every node. By default, this value
|
|
# is "server". We combine "node_name_prefix" with
|
|
# "nodes_id", to define nodes. Such as "server-64", "server-68"
|
|
# and so on. In every region, we give every node a specific name.
|
|
# Ensure that DNS can resolve the nodes.
|
|
node_name_prefix=server-
