1. Overview

This document describes the installation, configuration and usage of OnTimeMeasure-v1.0 on PlanetLab. OnTimeMeasure is a prototype measurement service for the GENI facility users. The measurement service can be used to perform centralized and distributed orchestration and provisioning of active measurements within experiment slices for purposes such as:

  • Network paths monitoring
  • Network weather forecasting
  • Network performance anomaly detection
  • Network-bottleneck fault-location diagnosis

The 'OnTimeMeasure researcher web-portal' enables a ProtoGENI/Emulab and PlanetLab user to register, create and monitor experiment slices on a geographically distributed resources in the GENI facility.

Before proceeding further, we highly recommend reading the OnTimeMeasure Tutorial and PlanetLab Tutorial.

  1. User Accounts: User must have registered accounts in the OnTimeMeasure Researcher Web-portal and PlanetLab.

2.2 PlanetLab Slice Creation and Configuration

Note: To obtain detailed information about PlanetLab slice creation, please refer to the 'PlanetLab Tutorial'

PlanetLab slice can be created using the web interface by logging into your account or by using the sfi-client (CLI).

2.3 Software Installation

Download the latest OnTimeMeasure release package at http://ontime.oar.net/download/OnTimeMeasure_latest.php.

Once you have downloaded the tar file, untar/unzip to see that it contains:

  • NodeBeacon.tar.gz
  • RootBeacon.tar.gz
  • README.txt

Next, login using SSH to each of the servers, copy the appropriate tar files over, and run the following commands to install the measurement service:

On the Root Beacon:

Software installation

tar xzf RootBeacon.tar.gz
cd RootBeacon/InstallScript
chmod +x ontime_software_install.sh
./ontime_software_install.sh

On a Node Beacon:

Software installation

tar xzf NodeBeacon.tar.gz
cd NodeBeacon/InstallScript
chmod +x ontime_software_install.sh
./ontime_software_install.sh

2.4 Software Configuration

Centralized Case:

On the Root Beacon:

MySQL configuration

cd RootBeacon/InstallScript
mysql -u root -p < BuildWebServicesDatabase.sql
mysql -u root -p < BuildMeasurementDatabase.sql
mysql -u root –p

At the mysql prompt, type

CREATE USER 'collector'@'%' IDENTIFIED BY '<collector password>';
GRANT ALL PRIVILEGES ON `Measurements` .  * TO 'collector'@'%';
GRANT ALL PRIVILEGES ON `WebServices` .  * TO 'collector'@'%';
exit

Note 1: Please use the <collector password> provided as part of the Slice information at Step 2 in the Researcher Web-portal.

Note 2: If remote access to MySQL on the Root Beacon is disabled, please open the port TCP/3306 and follow the tutorial at http://www.cyberciti.biz/tips/how-do-i-enable-remote-access-to-mysql-database-server.html

Invocation options configuration

perl config_wizard.pl

Follow the steps as directed by the wizard script.

On a Node Beacon:

Invocation options configuration

perl config_wizard.pl

Follow the steps as directed by the wizard script.

Note: If you want to customize the parameters on invoking measurement tools, you can manually modify the "runtool.conf" which locates in the "NodeBeacon/etc" folder.

On the Web-portal:

Login to the OnTimeMeasure Researcher Web-portal and provide the Slice RSpec information.

2.5 Software Invocation

Centralized Case:

On the Root Beacon:

Go to "Collector/" and run

nohup perl collector.pl &

Then, go to "../RootScheduler/"

nohup /opt/graphite/bin/run-graphite-devel-server.py /opt/graphite &
nohup perl file_server.pl &
nohup perl action_script.pl &

On a Node Beacon:

Go to 'Datagen/' run

nohup perl file_server.pl &
nohup perl node_scheduler.pl &
