Cloud Monitoring.

[jay]

Hi Members,
I have finally decided to do my thesis on Cloud
monitoring. Here is the working title.

"Investigation of different Network Monitoring Tools to detect
parameters critical to Cloud Computing and their Network Relevance."

I wanted some ideas in how to broaden my research. I currently plan on
investigating Nagios, Ganglia, Collectd to find out which parameters
and metrics are important then the others. Can I get some suggestions
in how can I use the results of this research to apply on SLA and
security. Just detecting the more important parameters would not be
enough, so I want to know which fields can I use the results in.
Really appreciate your help like always.
Thanks,
-Jay Flora.

You probably want to include Wireshark in your list of tools, at least
so you can calibrate the other tools against what is really going on
on the wires.

The key parameter is network latency, especially variance in latency,
and since systems are allocated in the cloud without direct control or
knowledge of placement, it could be interesting to try to figure out
the network topology that you got, from first principles of the
behavior observed. i.e. how many network hops are there between two
EC2 instances chosen at random, and how congested are those hops.
Given this kind of insight, a re-allocation algorithm could detect
poorly located EC2 instances that are failing an SLA and try to
replace them with ones that behave better.

Let us know if you figure out something like that, it would be
useful :-)

Are you using those tools as an example or are you just using those tools
in your research?
I think in order to determine the fields, I think as Adrian suggested, you
need to know a little how clouds are provisioned, and about their general
topology.
Next, from a high level what are important business SLA parameters.
If you are a web farm, you might value one set of parameters.
If you are running high performance applications, simulators or
things that need to finish Fast, of course perhaps another set of
parameters.
So you should probably figure out what types of things are good to
do with clouds and what types of SLA's are out there. Same with Security.
You need to know how the clouds are constructed to know the security models
and then what type of security is necessary for different types of
businesses. From there, I think the monitoring parameters will fall out
from that. You then need to determine if you can actually monitor them with
the tools you have chosen and by what perspective. Ie, if you have
monitoring in the cloud, but the business user is monitoring from their side
what is the parameter in the SLA? Latency comes to mind.

You would perhaps want to include Solarwinds as well

@ Adrian:

you've hit the nail on the head. That is what I am exactly looking at.
Applying the results of finding out the more important parameters in
order to improve SLA and security. your idea is really good. I am
getting some more study done to make the topic more concrete before I
go to my adviser to get the topic approved.
