Response Time Monitoring
Response time monitoring Response time monitoring is testing how fast is your site.

Response time monitoring is testing how fast is your site. It might be accessible, but bad performance can still make it unattractive for the clients. The monitoring of the response time allows you to check how the site acts as the time goes on. Do any of the scheduled tasks, like backup, updates etc affect the performance? Does the site works well for the whole world, or some regions of interest could meet a confusing delay?

HostTracker provides a possibility to check the reaction of your site. Select Response time check on the main screen:

Create ContentCheck Task

Then, select the largest satisfactory response time for the site. Is this value is exceeded, you receive a notification. Also, all the statistics is stored in the check log, and response graph is generated. You may check this data at anytime.

NOTE! Response time depends on the distance between the datacenter of your site and our checking server. It might be large enough for a remote country. To decrease this effect, select a checking region in advanced options.

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.

How to monitor availability of any web site?

The main feature of HostTracker monitoring service is the regular checks of web sites with monitoring intervals from 1 minute. Moreover, the HostTracker’s dedicated global monitoring checkpoints network currently includes more than 140 servers all over the world.

The main feature of HostTracker monitoring service is the regular checks of websites with monitoring intervals from 1 minute. Moreover, the HostTracker’s dedicated global monitoring checkpoints network currently includes more than 140 servers all over the world.

Each test is simulating the visit of a real user. If this imaginary visitor is able to load the site – everything is ok, otherwise – the site is revised again by a certain algorithm (just to be sure). Then, if an error was identified, it is recorded in the database and the notification of unavailability is sent. This is the easiest way to check the site’s availability. If you are interested, HostTracker has a great deal of more sophisticated tests to offer.

Types of tools for web accessibility evaluation

Here are some quick checks you can start with immediately that will move your web site toward better accessibility. It is worth noting that these checks support different protocols.

For example:

  • HTTP - this is an ordinary request, which is obtained from the user's browser.
  • Ping – helps to test site or server network connectivity. 
  • TCP-port - tests the site-to-application connectivity.
  • Database Check - a health check which can ensure that the web server can connect to the database and can also help in monitoring of other vital features. For those seeking a possibility to check the data on the page, there is a content check function. In this case, the virtual client is not just logging in, but also looking for the presence or absence of certain words and phrases. This feature helps you to detect whether some important section of the text has been lost. Moreover, it helps you to spot any mistakes on the page at once.
  • With HostTracker service you can also monitor the response and loading time of your web site. Furthermore, the corresponding data is being written to the inspection logs.

Armed with all these tests, you’ll be eager to collect extensive and thorough information about your web site. You’ll be entitled to know when, why and how did your web site stop working. For example, when the network, server or web site itself are down. Moreover, by using HostTracker, you can immediately detect when web site performance goes down and omit causing any inconveniences for your users. Or even more – you can easily recognize when some data isn’t regularly retrieved from the database. All these tools can help you pinpoint and rectify performance and speed issues with any publicly available web site. It, definitely, saves your time! And, in this case, downtime is small.

Interesting fact:

Almost all HostTracker’s customers are eager to reach 99% or higher uptime. By the way, the data from this service could be a good support in your future confrontations with hosting partner. Truly, many HostTracker’s customers have found a reliable web hosting partner or made him fulfill all promises and commitments according to the contract.

  • HostTracker provides options for monitoring the domain and SSL certificate expiry dates. This problem seems to be handled easily, as the registrar sends alert notifications, but history provides plenty of notification neglect examples.  Dropping the domain name is a widely spread problem. Actually, Microsoft has encountered it twice.
  • Also HostTracker is one of the best resources that can help to find out if your IPs or domains are on some SPAM-database (so called DNSBL). Apparently, if it seems that you're engaged in spamming or other unwanted online behaviour, your IPs or domain could get blacklisted and blocked. The blacklist usually contains email servers suspected of spreading spam or servers that have been infested with some nasty malware etc. 

Most Internet service providers and web servers use these blacklists to detect IPs linked to computers with pervading spam or unwanted activity. And the problem is: you can be blacklisted accidentally and be unaware about it. If it happens, your rankings will go down or disappear entirely. You can be truly innocent of any deliberate wrongdoing and still be on the list. For example, if you share your web hosting with someone unreliable. With this monitoring function you can be always aware if your company’s domain name is blacklisted and be ready to deal with it. You're likely to come across contacting the list by email or passing through some sort of automatic procedures in order to prove that you are not a robot when you’ll be trying to get off a blacklist.

HostTracker service settings

All above-mentioned checks teem with the wide variety of options:

  • Maintenance planning and scheduling – allows you, for instance, not to catch the errors during the server upgrade period.
  • Checks from a particular location- as outlined above, there is a huge network of global monitoring checkpoints, and it is possible to choose only regions with potential clientele:

  • Delay alerts – this option will postpone alert notifications for a specified time span; manage notifications in line with the importance of issues; control the life cycle of both alerts and their notifications.

As regards alert notifications option, clients will find themselves spoiled for choice. HostTracker provides notifications via e-mail, SMS and, by extension, via Skype, Hangouts and voice call. The most striking one - POST request. There is a possibility to send a request to a specific web server (e.g. to restart the web site automatically).

HostTracker service has an API, which allows pieces of software to interact. It is considered as a contract provided by one piece of computer software to another.

The next HostTracker’s advantage is that the service doesn’t require a lot of system resources (e.g. installation any client software). Almost all features are operating using cloud services, and can be configured with only HostTracker’s web site tools. And service settings, definitely, won’t take much time!

Generally speaking, the service is still being developed, as well as, the monitoring network expands, new tools pop up and so on. Considering new tools, they are being developed in response to the requests made by clients. Please don’t hesitate to contact HostTracker’s admins if you have any further suggestions about extra tools which yet aren’t provided by the service.
