Application Monitoring Should Encompass Application Performance Management In Totality

anagement or review of application performance can often be incomplete because it tends to concentrate on the process of monitoring alone, and not for errors that may be expected or anticipated to occur in the lifecycle of the application. One of the reasons for this could be that anticipating problems or errors is never an easy task. Further, problems that do not have a precedent are often not easy to predict. Application monitoring is an intrinsic part of performance management, but it cannot prevent issues and application failures by itself, but if it is applied in a thorough manner, it may help raise timely alerts and reveal corrective measures that could be taken.

Elements to take care of, when managing application performance

Performance management needs to focus on whether the application will meet its end-user expectations or not. Outline application expectations, if needed, before going ahead with the monitoring agenda. Application monitoring will work best when it goes hand-in-hand with end-user expectations. Understanding user expectations will also help you outline a monitoring plan that will take precise as well as overall care of all the most important areas within the application. Another advantage to outlining user expectations is to ensure that you have all the monitoring tools in place. This will also ensure optimizing of the application performance monitoring process itself.

Remember to also measure the impact of application monitoring on the performance of the application, versus the results in case there is no monitoring in place.

How to determine the ideal time for application monitoring?

There is no fixed way by which to determine the right time to begin application monitoring. However, certain elements can become pointers.

> Over utilization: If an application is being utilized above its core capabilities, it may utilize more memory and need monitoring to pinpoint the precise problem. Over utilization may occur in terms of usage time or the number of users accessing it at any given time.

> System crash: At times, errors may occur unexpectedly. This can result in sudden breakdown or total stopping of the application’s functions. Application monitoring that is thorough and comprehensive can catch a potential error before it brings about a complete system breakdown.

> Software failure: Software failures can be major contributors to application breakdown. However, regular monitoring can help raise timely alerts and allow you to take corrective action before the software fails entirely.

> Regular updates: If your software is not updated regularly, it can remain vulnerable to threats such as virus attacks or even hardware failure and configuration problems. Application monitoring can help determine critical updates needed and raise timely alerts so that appropriate action can be taken.

Critical elements

Application monitoring should cover everything, from server downtime to software, to processes and services, as well as hardware. Application performance monitoring can also include configuration changes. Application monitoring must be implemented keeping in mind it must be kept in mind that costs incurred in repairs and maintenance could be significantly higher than those incurred in monitoring.

Great Alternatives To iDVD Mac Lion

or those of you who have been using Macs, you are certainly happy to receive the new upgrades for your device. Sadly, though, the iDVD did not receive any upgrades in the new iLife ’11 suite. This has somehow disappointed many users but all hope is not lost. You can still be able to download iDVD software that will enable you to continue burning your stuff to DVD discs. Developers have come up with several great alternatives to iDVD Mac lion. Even though these apps do not work as well as Apple’s iDVD, they are the next best thing consumers have. Some of these alternatives are:

  • MovieGate

This is a wonderful application from Small DVD but it is not as powerful as iDVD. However, it allows users to create DVDs that have chapter support and animated menus with subtitles, sub-menus, and photo slide shows. Many people do not find the interface of this app nearly as attractive as that of iDVD. Nevertheless, if you desire DVD authoring software that offers continues updates, then this might be great for you. MovieGate is available for free download.

  • SmallDVD

This simple tool allows you to take any type of video files and add them to a DVD ISO image, which you can then burn onto a DVD disc via a disc utility. This app does not have any features. However, it is appealing to most people because it creates simple DVDs that have static background menus. An added advantage of SmallDVD is that it creates an ISO file that you can then share to iDisk or DropBox. Someone else can then be able to download and view the fileon another PC using the ISO only. You do not need an optical drive. This application is also available for free download.

  • Roxio Toast 10 Titanium

Many people have the impression that Toast is meantonly for making DVD backups of data or creating disc-to-disc copies. Nevertheless, this tool can also create anexcellent custom DVD, which you can be able to play on any DVD player. The custom menu and the creation controls of Toast are not as impressive as those of iDVD are. Even so, the software has amazing features of its own such as the capability to burn Tivo, web videos and EyeTV directly to a DVD disc. It also allows you to create photo slides shown on the DVD directly. The software is available for less than $90.

MDM Solutions

Mobile Device Management (MDM) is fast becoming a somewhat competitive game and finding the right solution is a minefield. Who’s best at what and which of the excellent options are right for your company?

A breakdown of just some of the best MDM solutions and their vendors is an important tool and will arm companies in their search for the right solution for their needs.

• Absolute Manage: Absolute Manage is available as a stand-alone package or as a component with AM. It includes some excellent functions such as device geotracking, deployment of in house apps and detection of jailbroken devices.

• Airwatch: Airwatch is without a doubt one of the strongest MDM suites out there. Reviews for Airwatch are so far strong and their iOS support is extremely comprehensive.

• IBM: Highly recommended in general, IBM offer strong support and high security… perhaps the highest out there.

• MobileIron: MobileIron supports all phone devices but not desktops. A relatively new company but forging ahead in the popularity stakes.

• Symantec: Not newbies to the business of device security but certainly doing an excellent job of providing all that’s needed and more. For a trusted name, Symantec are an excellent choice in terms of MDM solutions.

• FancyFon: Supporting all mobile devices and relatively new, FancyFon is fast making a name for itself in MDM and is well worth checking out especially as it supports Apple’s 1OS 5.

There are of course many MDM solutions out there and vendors are offering features which are in some cases vastly different to one another. The main points to take into consideration with regards to security are that no MDM solution is infallible and that there are weak spots still to be ironed out with some contenders.

It is important to note that MDM providers (all of them!) use exactly the same system for managing iOS devices… that is an XML doc. And the spec for this is defined by Apple.

As a result, the features of each MDM solution are more or less the same. Some features may be erased or compromised by the user, including root configuration profiles which are removable.

iTunes may also make devices vulnerable to being wiped completely… ensure that you are fully informed of the pitfalls of each before you decide which MDM solution to go for.

There are so many MDM vendors currently cropping up that it’s a slightly overwhelming process to decide which to choose; it is worth remembering that now it is the task of the various MDM providers to work out how to make themselves stand out.

When one vendor rises head and shoulders above the other, this may not be a permanent situation though… in a world where MDM is developing at a breakneck speed it is sensible to retain an open mind.

Read the reviews and consider the weaknesses if any of the solutions which interest you; your company is an individual and no two organisations can hope to benefit from the same features.

It makes sense to remember that BYOD is bringing both convenience and speed to many workplaces in terms of access to data but the issue of security will be ever present and dropping the ball at this early stage is not a good idea. Keep up to date with new developments and ask questions as they occur. Your MDM provider should be at the ready with the answers!

Fiber Optic Connectors And The Complete Guide

The network cabling industry’s fiber optic manufacturers over the last few decades have been on a constant mission to develop the better fiber connector. This means lower cost, lower dB losses, easier to terminate out in the field. There have been over 100 connectors developed over the years but a select few have stood the test of time and beat out their competition. Below we will talk about the most common.

A fiber optic connector terminates at the end of a fiber optic cable and is used when you need a means to connect and disconnect the fiber cable quickly. A fiber splice would be used in a more permanent application. The connectors provide a mechanical connection for the two fiber cables and align both cores precisely so the light can pass through with little loss. There are many different types of connectors but many share similar characteristics. Many connectors are spring loaded. This will push the fiber ends very close to each other so as to eliminate airspace between them, which would result in higher dB losses.

There are generally five main components to a fiber connector: the ferrule, the body, the coupling structure, the boot and the dust cap.

Ferrule-the ferrule is the small round cylinder that actually makes contact with the glass and holds it in place. These are commonly made of ceramic today but also are made of metal and plastic.

Body-This sub assembly holds the ferrule in place. It then fits into the connector housing.

Connector Housing-This holds all sub assembly parts in place and has the coupling that will connect to the customer’s equipment. The securing mechanism is usually bayonet, snap-in or a screw on type.

Boot-This will cover the transition from the connector to the fiber optic cable. Provides stress relief.

Dust Cap-Just as it implies will protect the connector from accumulating dust.

There are many types of connectors on the market. The major differences are the dimensions and the method of connection to equipment. Most companies will settle on one type of connector and keep that as a standard across the board. It makes sense because all equipment has to be ordered with that specific connector type and to have 2 or 3 different connector types can get messy. For typical network cabling projects today LC is fast becoming the shining star of fiber connectors. LC is a small form factor connector which means it requires a much smaller footprint in your IT closet. Thus you can fit many more LC connectors into you fiber panels then say ST or SC connectors.

  • ST Connector

The ST connector (or Straight Tip) was the first popular connector type to be used as a standard for many organizations in their fiber network applications. It was first developed by AT&T. Often called the “round connector” it has a spring loaded twist bayonet mount with a 2.5mm round ferrule and a round body. The ST connector is fast being replaced with the smaller, denser SFF connectors.

  • SC Connector

The SC connector is a push-in/pull-out type connector that also has a 2.5 mm ferrule. It is very popular for its excellent performance record. The SC connector was standardized in TIA-568-A, and has been very popular for the last 15 years or so. It took a while to surpass the ST because of price and the fact that users were comfortable with the ST. Now it’s much more competitive with pricing and it is a very easy install, only requiring a push in and pull out connection. This is very helpful in tight spaces. Simplex and duplex SC connectors are available. The SC was developed by the Japanese and some say stands for Standard Connector.

  • FDDI/ ESCON Connectors

You may see FDDI and ESCON(IBM) duplex fiber connectors in older installations. These connectors will mate to their own networks and usually will be seen at the wall outlet locations. These connectors use a squeeze tab coupling mechanism. The closet side of the fiber will usually have a standard ST or SC connector. The FDDI/ESCON connectors can be mated to SC or ST connectors since they both have a 2.5mm ferrule. An adaptor would be required in this case. The FDDI stands for Fiber Distributed Data Interface.

  • LC Connector

The LC connector was developed by Lucent Technologies, hence the LC. It is a Single Form Factor Connector that has a 1.25mm ferrule. The attaching mechanism is similar to an RJ-45 connector with the retaining clip. It is a smaller square connector, similar to the SC. LC connectors are often held together with a duplex plastic retainer. They are also very common in single mode fiber applications.

  • MT-RJ Connector

MTRJ stands for Mechanical-Transfer Registered Jack and was developed by Amp/Tyco and Corning. MTRJ is very similar to an RJ type modular plug. The connector is always found in duplex form. The body assembly of the connector is usually made from plastic and clips and locks into place. There are small pins present that guide the fiber for correct alignment. MTRJ’s also are available in male or female orientation. They are only used for multi-mode applications. They can also be difficult to test because many testers on the market do not accept a direct connection. You usually need to rig up a patch cord adaptor kit to make testing possible.

  • FC Connector

The FC connector you may find in older single mode installations. It was a popular choice that has been replaced by mostly ST or SC type connectors. It also has a 2.5mm ferrule. They have a screw on retaining mechanism but you need to be sure the key and slot on the connector are aligned correctly. FC connectors can also be mated to ST & SC’s through the use of an adaptor.

Panduit Opti-Jack Connector

The Panduit Opti-Jack is a clean, tough duplex connector cleverly designed around two ST-type ferrules in a package the size of a RJ-45. It has male and female (plug and jack) versions.

  • Volition Connector

3M’s Volition is a slick, inexpensive duplex connector that uses no ferrule at all. It aligns fibers in a V-groove like a splice. Plug and jack versions, but field terminate jacks only.

  • LX-5 Connector

LX-5 is like a LC but with a shutter over the end of the fiber.

  • MU Connector

MU looks a miniature SC with a 1.25 mm ferrule. It’s more popular in Japan.

  • MT Connector

MT is a 12 fiber connector for ribbon cable. It’s main use is for preterminated cable assemblies and cabling systems. Here is a 12 fiber MT broken out into 12 STs.

This connector is sometimes called a MTP or MPO which are commercial names.

Hopefully this guide may help you get an idea of what options are out there for your fiber optic connector needs.
