Monitoring Host Daemon

Daemon that monitors physical hosts performance

Benchmarks used

• [CPU] Sysbench

Installation

To install the monitoring-hosts daemon you will need a virtual machine with a fresh install environment and with the configuration described below.

Minimal Server Configuration

OS: Ubuntu 14.04
CPU: 1 core
Memory: 1G of RAM
Disk: there is no disk requirements

Steps

1. Update and Upgrade your machine

   $ sudo apt-get update && sudo apt-get upgrade

2. Install pip and dependencies

   $ sudo apt-get install python-setuptools python-dev build-essential
   $ sudo easy_install pip

3. Install git

   $ sudo apt-get install git

4. Install sysbench

   $ sudo apt-get install sysbench

5. Clone the monitoring-hosts repository

   $ git clone https://github.com/bigsea-ufcg/monitoring-hosts

6. Access the bigsea-loadbalancer folder to install the requirements

   $ cd monitoring-hosts/
   $ sudo pip install -r requirements.txt --no-cache-dir

Configuration

Backends

You can use two types of configuration, no backend (the output will be written in the output_dir), or use monaca (the output will be directlly published.

No backend

default.cfg

[DEFAULT]
type=CPU
name=sysbench
# Full path to access the sysbench.json file that is in sample directory.
parameters=/path/sysbench.json
output_dir=/tmp
backend=

Monasca backend

sample/default_monasca.cfg

[DEFAULT]
type=CPU
name=sysbench
# Full path to access the sysbench.json file that is in sample directory.
parameters=/path/sysbench.json
output_dir=/tmp
backend=OS_MONASCA

[monasca]
username=<@username>
password=<@password>
project_name=<@project_name>
auth_url=<@auth_url>
monasca_api_version=v2_0

Sysbench Parameters

You can set the number_of_threads and the max_primeparameters used by sysbench by editing the sysbench.json file located in the sampledirectory.
