Availability
Availability Availability of a site shows if a site is accessible from the Internet.

Availability of a site shows if a site is accessible from the Internet. This term is also about access to a server, database or another entity. As all objects in the Internet are based on comlicated infrastructure, nothing can be available always. The question is how to measure it, what is normal and if we may affect it anyway. The measurement of availability is connected to terms Uptime and Downtime, which show for how long a site is unavailable. However, these values can not create the full view of the situation. There could be many reasons of unavailability - server or connection problems, application error, overload of the site and so on. To avoid or shorter the failures, it is needed to supervise the site and analyze the errors, if they happen. For these purposes there are special monitoring tools, which help to increase to availability of the site, collect statistics and provide necessary information about the errors for fast repair. These tools are called Website Monitoring services.

Snapshot - instrument for site supervision

How does the site look like when I’m not looking at it? What if it looks bad or does not work at all? HostTracker offers an instrument for site supervision - snapshot feature. Let’s take a look at its practical application.

What’s going on with my site?

Now it’s usual to use different services and applications for site maintenance and support, and sometimes they do report some problems. Often we feel the lack of information - Google Analytics or a similar service reports the downtime and renewal, but likely we will never know what exactly has happened. To investigate the issue, it is necessary to review the logs, write to hosting support and perform many others exhausting actions, frequently - with no result. There are also more interesting cases - when a site is not available from a certain country or is not downloaded completely. Such problems could long for months, or even years, till they are accidentally detected. One more important issue - content check. It will automatically review the content of the site and inform the responsible staff in case it has disappeared - for example, something has not been able to be downloaded from the database. But it’s hard to find the cause if the issue is short-term, because people usually do not sit in front of a laptop refreshing the page every minute. To resolve the problem, HostTracker offers a new feature - snapshot. It is very simple in use and does not require any additional adjustments. The service simply makes a snapshot of the checked page every time and saves it for review in two ways: page source code and html-view. This let you easily see how the page looks at the moment of failure, understand what’s wrong and fix the problem quickly without spending time for diagnostics. It saves lots of time for server administrator, developers and other concerned people.

How does it work

Doing the regular checks, our servers with predefined interval try to download the checked page. Additional algorithms could be used at the moment - the page could be parsed for keywords to make sure that this is the one we are looking for (there are cases when an error page returns 200, Ok, http code, or when redirection is activated in case of error). If there is no error - fine. But if there is, it will be written down into the HostTracker log, which is easily available from the web. Then, notification are sent and a snapshot is made.

The snapshots could also be found in the log - if several errors were detected, a different snapshot will be available from each one.


Though there are some remarks. First, we do not run javascript while making snapshot - same thing for regular check. Second, the error must be detectable. It means, the server must return something. In case of timeout or connection error - snapshot will not help, and only a corresponding record will remain in the log.

In today’s high speed, high pressure and high-stress world it’s utterly important to keep up with things going on with your website. Being well-informed means being in the know of how speedily the monitoring service can contact you - as how will you save the world if you don’t know what’s happened in time?

In today’s high speed, high pressure and high-stress world it’s utterly important to keep up with things going on with your website. Being well-informed means being in the know of how speedily the monitoring service can contact you - as how will you save the world if you don’t know what’s happened in time? HostTracker gives you this unique opportunity to be the first to find out when your website goes down or stops functioning the way it should.

However, there are a couple of factors to keep in mind. All issues – especially serious ones - need to be clearly prioritized. By far, keeping up with all warning notices without managing their preferences beforehand can be really challenging. Chances are, that at some time in your life, you’ll simply get your mail drowned in the notification spam.

In light of this, HostTracker provides a set of default notification preferences. Generally, they are split up into three categories:

  • Short-term issues - the alert is not sent at all;

  • Major issues – the administrator is notified right away.

  • Long-term issues – the manager is notified right away.

If your website falls into one of these three groups, HostTracker emails you at once. There are many ways you could configure HostTracker to send notifications out. The direct message notifications could be sent via e-mail, SMS, Skype, Viber, Hangouts, Telegram or Slack. It’s up to you to choose which method (methods) you want to use. Rather, if you have your phone number attached to your HostTracker account you can also turn on SMS or voice call notifications. HostTracker values its customers' time above all else and provides notification scheduling as well. Therefore, you won’t be annoyed with your phone buzzing all night long, as well as, you’ll get your notifications in small doses in time throughout the day.

Additionally, there are several sub-categories based on following events:

  • If the website experiences some performance problems;

  • If the website is offline;

  • If the website is back online or performance problems have been successfully sorted out.

Whilst the first and third options are clear to understand, the second is likely pretty vague. So when can you expect your alerts on the second occasion? HostTracker will drop you multiple timely alerts every time when the check is unsuccessful – note, we consider only confirmed minor/major problems.

The system work is organized in such a brilliant way, that every responsible person for the website well-being happens to be protected from being spammed by multiple unimportant notifications or reminders, and get them only on the serious events. For example, suppose your website is managed by both the administrator and manager, and is currently offline. In that case: first, the e-mail will be sent directly to the administrator; second, after quarter an hour the administrator will receive the direct SMS notification; third, if that situation does not change after more than an hour, the SMS will be sent to the manager, to boot. Sounds ideal, isn’t it? While it may be ample for your needs, HostTracker offers one more feature – Time of activity - in order to help you solve your problems in a much more quick and efficient way.

One reason why using Time of activity option is of interest to our clients is that they could enjoy a good night sleep without worrying whether their shift administrator will miss an important alert. By the way, all outlined options are fully-customizable.

As a customer-oriented company, we provide not only different useful tools for smooth website life online but also lend an air of ‘peace and relaxation’ to our customers – they are not stressed out by annoying ongoing notifications. Various settings allow our customers to clearly define and assign roles and responsibilities for team members, collaborate better and ultimately, have an overview of the whole website performance and keep track of the all technical difficulties they experience with their website. 100% customer satisfaction is our goal.
