When you want to compare historical volumes or activity at a particular moment in time, Cacti can provide it.

Culture and tools

As you might expect from an open source tool set, both of these tools are highly extensible. We have been able to write and adapt agents to interface with them, with the exception of our database monitoring, and we have been able to monitor and trend all our services.

I spoke above about getting the culture right, putting these critical volumes onto big flat screens, making them obvious to everyone in your operations and service team. This was the single most important cultural change we made next to implementing an ITIL service culture.

The real question here is how we’ve been allowed to put all this instrumentation all over our application. Most government contracts are outsourced, but we chose to in-source our operations and development teams.

In-source, out-source, open-source, right-source

It’s about your technology strategy?

To understand this we need to talk about technology in a business context. Most organisations have either an implicit or explicit technology strategy. Within our organisation our Technology Strategy provides us with a framework that allows an organisation to make ‘good’, strategic choices, i.e. Hardware, software, monitoring systems, hosting providers. These choices are deployed within a governance framework to ensure that the business and service models that are dependant on technology can be delivered now and the future.

At the risk of stating the obvious, the selection of technology and service model an organisation chooses can mean the difference between a successful business and one that fails. As a consequence, organisations and IT directors tend to be conservative in there decision making.

At a simplistic level, technology is used for three things within an organisation:

  • to run the business
  • to change the business
  • to innovate

Unless you are a start-up, the bulk of investment and cost is already sunk in running your company. Changing the company IS usually occurs incrementally and takes the form of modifying the status quo. We are left with the shinny innovation tip of the cost iceberg to introduce new ways of doing things.

If we accept some of the above, we can see that technology strategies have considerable inertia, and unless there are some strong external pressures (failure to meet Service levels, company financial pressure, loss of market share), the adoption of new technologies is going to be slow. There is still a lot of COBOL out there!

So if you already don’t have a lot of open source in use, introducing it requires overcoming quite a lot of inertia.

As a company we have mandated the use of specific open-source operating systems and applications within our technology strategy where we can see cost and risk reduction. It’s worth saying that if our service was totally outsourced then these would not be our choices to make, other than at contracting and its very dangerous form to tell a supplier both what you want and how to do it.

Questions & Answers

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?

or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
can nanotechnology change the direction of the face of the world

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
