OnTimeMeasure-GENI Installation Document

Software License: 'GENI Project License (GPL)'

1. Getting Started

This document describes the installation, configuration and usage of OnTimeMeasure, which 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 ProtoGENI/Emulab and PlanetLab users to register, create and monitor experiment slices on geographically distributed resources in their facility.

Before proceeding further, we highly recommend reading the Early Experimenter Tutorial.

2. Requirements

The OnTimeMeasure software package has the following requirements:

  1. Operating System: Fedora 8
  1. Open Ports: For RootBeacon server: MySQL TCP/3306, Graphite TCP/2003 and TCP/17280, Collector TCP/7777, HTTP TCP/17290; For NodeBeacon server: BWCTL TCP/4823, Nodescheduler TCP/17249, HTTP TCP/17290
  1. User Accounts: User must have registered accounts in the OnTimeMeasure Researcher Web-portal and Emulab Network Testbed
  1. ProtoGENI slice: Create a new experimental slice in the Emulab website with at least 3 nodes. One is the root beacon. The others are node beacons.

Note 1: We suggest to use the ProtoGENI Cooked Mode to create a new slice. You can refer to our Experiences in Creating ProtoGENI Slices. If you still use the command line Emulab test scripts to create a slice, see the end of this document for the example RSpec.

Note 2: Following are the pre-requisite software and Perl modules, which will be installed automatically by the scripts delivered in the OnTimeMeasure release package.

Pre-requisite Software: MySQL, Graphite, Perl, Python, Iperf, Ruby, Bwctl-server, Bwctl-client, Cairo, Python_Twisted, Python_Piddle

Perl Modules: Config::Natural, POSIX, DBI, IO::Socket::SSL, Log::Log4perl, Net::SSLeay, Math::Random

3. Centralized Case Installation

3.1 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 Server:

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

On a Node Beacon Server:

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

3.2 Software Configuration

On the Root Beacon Server:

MySQL configuration

mysql -u root < BuildWebServicesDatabase.sql
mysql -u root < BuildMeasurementDatabase.sql
mysql -u root

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 change the <collector password> to a safe password.

Note 2: If remote access to MySQL on the Root Beacon is disabled, please open the port TCP/3306 in the firewall 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 Server:

Invocation options configuration

perl config_wizard.pl

perl node_scheduler.pl

If no error is reported, press '<CTRL>+a, d' sequence in the SSH window to keep the service running in the background.

4. Distributed Case Installation

4.1 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

Only the NodeBeacon.tar.gz is needed. Upload it to a node beacon server and run the following commands to install the measurement service:

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

4.2 Software Configuration

NTP Configuration

sudo vim /etc/ntp.conf

Edit the last line to:

server owamp.newy.net.internet2.edu

Restart ntpd service

sudo /etc/init.d/ntpd restart

BWCTL Configuration

Edit the BWCTL config: /etc/bwctld/bwctld.conf

Remove the comments on the below lines and edit them as:

allow_unsync
sync_fuzz 5

Edit the BWCTL limits: /etc/bwctld/bwctld.limits Change the regular limit to:

limit regular with parent=root, \
        duration=30, \
        allow_tcp=on, \
        allow_udp=on, \
        allow_open_mode=on

Restart BWCTL:

sudo /etc/init.d/bwctld restart

Note: For more detailed instructions to configure NTP and BWCTL, please refer to the BWCTL Tool website. (http://www.internet2.edu/performance/bwctl/)

Go to 'NodeBeacon/Datagen/' and run

screen
perl file_server.pl

If no error is reported, press '<CTRL>+a, c' sequence to open a new blank command window.

Note:Centralize and distributed share the same file server script. If you run both centralized and distributed on the same machine, you only need to run the file_server.pl once.

perl dist_scheduler.pl

If no error is reported, press '<CTRL>+a, d' sequence in the SSH window to keep the service running in the background.

2.3 Sliver Creation and Management

Create and manage a sliver by the Emulab test scripts.

  • Register a slice
    registerslice.py –n <slice name>
    
  • Create sliver inside slice
    createsliver.py –n <slice name> <rspec file>
    
  • Check sliver status
    sliverstatus –n <slice name>
    

Note: You may need to renew your sliver just after successful creation. For this,

renewsliver –n <slice name> <time>
