Integrated Management Framework Evaluation
This evaluation reviews the documentation and code used for the GEC10 Demo of the Integrated Measurement Framework demonstration for the milestone:
IMF: S3.d Documentation and Code Release (Completed late 05/13/11)
According to the IMF Post-GEC11 status, the IMF code is available as attachments the status page. The following perfSONAR components are available:
- Standalone command-line client for IMF measurements
- Standalone GUI client for IMF measurements
- Measurement Handler
- PubSub
- IMF Realtime service
In addition to the software, a login account is required to access http://ben.renci.org. To use the features in the PubSub_for_PerfSONAR package.
Evaluation Timeline: October 7, 2011
Integrated Management Framework Findings
Found various issues captured were captured in as bugs in the IMF track system. The list of issues found includes:
- Ticket 4 MH undocumented prerequisites and version error for makefile creation
- Ticket 5 Real Time package installation inconsistencies and error
- Ticket 6Real Time Readme issues
- Ticket 7 Pub Sub package issues
- Ticket 8 MH README Feedback
- Ticket 9 prepare_environment.sh fails with missing components plus other errors
Additionally had to request account on the server https://ben.renci.org and on the server geni-imf-dev.renci-dcr.ben. Access to the geni-imf-dev.renci-dcr.ben is only available via an OpenVPN connection, which requires additional Credentials. Each of these were acquired from the IMF team.
Integrated Management Framework How-to
Downloaded each of the 5 software packages available as attachments in the Code Snapshot section of the IMF GEC11 QSR.
Measurement Handler How-to
Unpacked and built the Measurement Handler package:
$ tar xvzf mh.tar.gz $ cd mh $ perl Makefile.PL
The perl command fails due to missing pre-requisite perl Modules: Date::Manip, Net::Telnet, and Thread::Queue::Any. Once installed was able to generate the makefile and proceed to the next step:
$ make make: *** No targets specified and no makefile found. Stop. lnevers@sendaria:~/IMF/mh$ perl Makefile.PL Argument "6.55_02" isn't numeric in numeric ge (>=) at Makefile.PL line 5. Checking if your kit is complete...

Realtime Service How-to
Unpacked and built the Realtime Service package:
$ tar xvzf perfsonar_imf_realtime.tar.gz $ cd perfSONAR_PS-IMF-RealTime $ sudo make install sed -i "s|/opt/perfsonar_ps/imfrealtime|/opt/perfsonar_ps/imfrealtime|g" ./etc/daemon.conf sed -i "s|/opt/perfsonar_ps/imfrealtime|/opt/perfsonar_ps/imfrealtime|g" ./etc/daemon_logger.conf for i in `ls ./scripts`; do sed -i "s|/opt/perfsonar_ps/imfrealtime|/opt/perfsonar_ps/imfrealtime|g" ./scripts/${i}; done mkdir -p /opt/perfsonar_ps/imfrealtime tar ch --exclude=etc/* --exclude=*spec --exclude=MANIFEST --exclude=Makefile -T MANIFEST | tar x -C /opt/perfsonar_ps/imfrealtime tar: doc/README: Cannot stat: No such file or directory tar: Exiting with failure status due to previous errors for i in `cat MANIFEST | grep ^etc`; do mkdir -p `dirname /opt/perfsonar_ps/imfrealtime/${i}`; if [ -e /opt/perfsonar_ps/imfrealtime/${i} ]; then install -m 640 -c ${i} /opt/perfsonar_ps/imfrealtime/${i}.new; else install -m 640 -c ${i} /opt/perfsonar_ps/imfrealtime/${i}; fi; done
PubSub How-to
Unpacked and built the PubSub package:
$ tar xvzf PubSub_for_PerfSONAR.tar.gz $ $ cd PubSub_for_PerfSONAR/IMF/
Met pre-requisites for Pub Sub system:
- Get account on https://ben.renci.org/.
- Got account on geni-imf-dev.renci-dcr.ben system. Access to this system requires OpenVPN access.
- Got Encrypted OpeenVPN Credentials to access the OpenVPN site.
- Installed OpenVPN as described at the BEN Wiki page named Using BEN VPN
- Install the network manager to configure OpenVPN.
The following packages had to be installed for OpenVPN and Network Manager:
$ sudo apt-get install openvpn network-manager-openvpn openvpn-blacklist network-manager $ sudo apt-get install resolvconf
Run the network Manager to configure the OpenVPN
$ sudo NetworkManager $ sudo nm-connection-editor
The encruypted OpenVPN Credential has to be unpacked usind a passphrase provided out of band:
$ gpg -d gpo-bbn.zip.gpg > gpo-bbn.zip $ unzip gpo-bbn.zip Archive: gpo-bbn.zip creating: gpo-bbn/ inflating: gpo-bbn/gpo-bbn.conf inflating: gpo-bbn/gpo-bbn.ovpn inflating: gpo-bbn/dh1024.pem inflating: gpo-bbn/ca.crt inflating: gpo-bbn/gpo-bbn.key inflating: gpo-bbn/gpo-bbn.crt
The file gpo-bbn/gpo-bbn.conf is imported into the Network Manager VPN settings to connect. Although I was not able to successfully import the configuration file, so I switched to invoking the OpenVPN from the command line:
nevers@arendia:~/IMF/VPN/gpo-bbn$ sudo openvpn --config ./gpo-bbn.conf --scrip t-security 2 Thu Oct 13 15:10:04 2011 OpenVPN 2.2.1 i686-pc-linux-gnu [SSL] [LZO2] [EPOLL] [eurephia] built on Oct 13 2011 Enter Auth Username:lnevers Enter Auth Password: Thu Oct 13 15:10:14 2011 WARNING: No server certificate verification method has been enabled.
