The benefits of network monitoring
As a business, when we invest time and money in our infrastructure, we expect that everything will work perfectly. However, we also know that such an innovative technology has limitations.
At HDCE, we make sure that your investment remains profitable. Thanks to the monitoring of your infrastructures, you are aware of the slightest problem. This tool insures not only the efficiency of your entrepreneurial activities, but brings you peace of mind.
In addition to a continuous real-time surveillance of all your applications, remote monitoring lets you save precious time and support fees and thus increases your profitability through continuation of your activities.
Remote monitoring allows real-time verification of your systems and warns you of the slightest deficiency (failure, slowing-down, error in the proactivity of systems, parts replacement). It then allows you to avoid any disaster or usual technological constraint that could stop your activities for an undetermined period. Remote monitoring can be used for the following applications:
- Web sites
- Application systems
This system can also provide you with important information such as response time, rate of success, rate of failure, etc.
What data can the systems provide?
As for the second page, the table shows several values such as moments when all is active and downtime periods.
Can we benefit from HDCE’s remote monitoring services even if we are hosted elsewhere?
In most cases, remote monitoring services are used for external hosting.
Planned downtime and unplanned downtime can be differentiated. Typically, planned downtime results from maintenance which disrupts the system’s operation and generally cannot be avoided with the design of the installed system. Planned downtime could include corrections of system software needing to be restarted or a system being subjected to a configuration revision that can become effective only after a reset. Generally, programmed downtime results from a logical management of events initiative. Unplanned downtime is the result of a physical event, such as hardware or software failure or an irregularity in the environment. Unplanned events of unavailability include power failures, failure of CPU or RAM components (or other defective hardware components), shut-off due to ever-heating, logically or physically cut-off network connections, breach of security or other applications, middleware or failure of operating system.
Numerous computer sites exclude planned downtime when calculating availability presuming that it has little if no impact on users. In so doing, they cannot pretend having a high availability. Systems having an actual high and continuous availability are relatively rare and more expensive than most. For certain systems, planned maintenance has no impact, for example, a business closed at night. This way, maintenance is programmed when all employees are away and there are no entrepreneurial activities.
Calculations in percentage
Availability is generally expressed as a percentage of the availability for a given year. The following table shows authorized downtime for a certain percentage presuming that the system must function at all times. It shows the translation of a given percentage of downtime of a system into the corresponding downtime expressed in years, months or weeks.
|Availability %||Annual downtime||Monthly downtime *||Weekly downtime|
|90 %||36,5 days||72 hours||16,8 hours|
|95 %||18,25 days||36 hours||8,4 hours|
|97 %||10,96 days||21,6 hours||5,04 hours|
|98 %||7,30 days||14,4 hours||3,36 hours|
|99 %||3,65 days||7,20 hours||1,68 hours|
|99,5 %||1,83 days||3,60 hours||50,4 minutes|
|99,8 %||17,52 hours||86,23 minutes||20,16 minutes|
|99,9 %||8,76 hours||43,8 minutes||10,1 minutes|
|99,95 %||4,38 hours||21,56 minutes||5,04 minutes|
|99,99 %||52,56 minutes||4,32 minutes||1,01 minutes|
|99,999 %||5,26 minutes||25,9 seconds||6,05 seconds|
|99,9999 %||31,5 seconds||2,59 seconds||0,605 seconds|
|99.99999 %||3,15 seconds||0,259 seconds||0,0605 seconds|
