A word about LAMP

1. On the Rspec, the user chooses which nodes will be “instrumentized” with LAMP– The user also chooses one (or more) node to

host the LAMP Web Portal

2. Using this modified Rspec, the slice is created as usual by the CMF

3. The slice manifest (returned by the CMF) is converted and sent to UNIS

How the slice is instrumentized? (1)

A word about LAMP

4. Through the LAMP Web Portal, one can enable and configure measurement services on all nodes that comprise the slice– The “Portal node” knows the slice’s topology by

querying UNIS…

5. All changes made on the Portal are sent to UNIS

6. All nodes pulls the configuration from UNIS (every 5 minutes) and applies the new configurations on themselves.

INSTOOLS:Some considerations

718/05/2012

Considerations

• According to Jim Griffioen (2011):– “[...] INSTOOLS does not do well in defining standards so

that other user interfaces can get access to the data”– So...– “Our goal is to use perfSONAR and/or the I&M architecture

to define standard ways to access the collected data from external visualization tools.”

INSTOOLS and perfSONAR: a love story?

818/05/2012

Considerations

• Some perfSONAR interoperability already exists!– Data is stored in rrd format (that can be understood by pS

clients)– “We have implemented (and tested) a perfSONAR service

that reads the rrd files on our MC, and, in turn, makes them available to external I&M user interfaces (e.g., existing perfSONAR tools)”

– Moreover, pS also brings the ability to perform active measurements [remember that INSTOOLS performs only passive measurements...]

Considerations

• All these information is accessible through INSTOOLS Portal, LIVE!

• The measurements are gathered via SNMP and SSH

What exactly can INSTOOLS measure?

1018/05/2012

Considerations

• 1 MC per Aggregate• Installs additional

software on each node (SNMP daemon, tcpdump, netflow, ...)

• Each node becomes a MP and send its data to the Aggregate’s MC

How does INSTOOLS instrumentize the user’s slice?

Demonstration

• The Component Manager returns a Manifest informing:– The slice’s topology– The number of resources and their characteristics

• The original Rspec is changed by:– Adding a new sliver (usually a node) to act as the MC– Specifying a custom OS kernel to be loaded on the MC– Creating all necessary links between the MC and other nodes– Adding monitoring software to each node of the

slice/experiment (making them MPs)• The modified Rspec is then sent to the CM, who rebuilds

the slice

But what really happens after clicking the “Instrumentize” button?
