POST method example
POST method example Example of monitoring a webform with POST method.

For example you have such simple form:
form action="some-site.com/some-script.cgi" method=post
input type=text name=login value=''
input type=password name=password value=''
input type=submit name='Submit' value='Login'
/form
User fill this form with value login: Peter and password: 1234 and click submit. If everything is Ok, script prints "LoginOk" on the result page.
For making a monitoring task to control this script, create task with next fields:

URL: some-site.com/some-script.cgi
Http Method: choose POST
In "POST parameters" field you should add three strings:
login=Peter
password=1234
Submit=Login
In "Content check" field: LoginOk
Results: HostTracker with every check will fill this form and assume that it is OK if the set keyword LoginOk is returned.

"Thank you so much for your service. We were suspecting problems with our hosting company but they denied any problems saying the issues must be at our end. We know we do have issues at our end but still suspected that wasn't the entire story. Your service was able to prove that they are indeed going down regularly - on average twice a week during the trial period. Thanks again for providing the information we needed to make a proper decision on this issue."

Monitoring domain and SSL certificate expiry dates

▶ Monitoring domain and SSL certificate expiry dates.

▶ How to activate the SSL certificate monitoring tool and domain monitoring settings?

▶ It takes only several minutes with HostTracker

So many domain names are lost in this fashion. The domain name holders have their names taken away by others, simply because they miss the renewal alerts and they do not notice when their domains are not running the show anymore. Although the whole system for domain name holders is not very practical or sensible, reality confirms that dropping a domain name is a significant problem nowadays. Anyone who holds a domain name is very much prone to losing it, ranging from big corporations, like Microsoft, to small private firms. Trying to solve this problem, HostTracker has developed utterly useful tools that highly increase the chances to reach 100% uptime.

Controlling tools

Registrars are obliged to keep the registered name owner always updated on the status of a domain and must notify of the impending expiration at least two times. One of these notifications must be sent about one month prior to expiration and one must be sent about one week prior to expiration. But “In theory, theory and practice are the same. In practice, they are not”. That’s why a lot of very bad things keep on happening. For instance:

  • Alerts go to the spam folder;
  • Responsible employees are taking time off work;
  • Or just there is something more important that should be solved just at this moment and the domain renewal is put off for the better times.

Problems like these occur very often.  Moreover, when we face them - no one can recall the timing of the registration, the timing of payments, the cards from which the money was written off etc.

Are you getting the idea that it’s truly important to pay attention to this stuff? Use HostTracker tools. The service will monitor your domain/SSL certificates for many different status changes, such as when a domain becomes registered, when it drops and becomes available, when it's renewed and everything. You can enable automatic summary reports that are emailed on a daily / weekly / monthly basis (or at any interval you choose). The reports can include renewal dates of registration and any other useful information and can be sent, for example, via SMS, email or a Skype. These instruments are also fully configurable and can be used together or separate with regular uptime checks.

Domain Monitoring Service Settings

Applying domain monitoring settings takes several minutes:

simply enter the domain name. You can click on "Add list" to monitor more than one website. You may also configure additional options by clicking on "Subscriptions" bar:

  • “Up” - the domain renewal notices are emailed one month, 7 and 3 days prior to expiration.
  • “Down” - you are notified that your domain name has already expired.
  • “Repeat” - you receive alerts every day until you renew the domain name.

Put tick marks next to the contacts of people, who should be informed in case of any problems.

If you want to be notified not only by email, but also by other messengers (Skype, Viber, Hangouts, Telegram), add them in the "Add Contact" bar or in the "Notifications" menu on the main page screen.

How to activate the SSL certificate monitoring tool

Since Google announced that they’re going to be using whether or not a server uses SSL as a ranking signal, the number of people interested in purchasing SSL certificates has skyrocketed. Why are SSL/TLS certificates so beneficial? 

The idea of using SSL/TLS certificates is crystal clear, as it is a type of encryption used for securing web sessions. HTTPS keeps both your websites and your customers' personal information private and secure. As when a SSL certificate is used, the information becomes indecipherable to everyone besides for the server you are sending the data to. This protects it from "domain slamming", "email phishing" attacks and other harmful activities.

Therefore, it is vital not to miss SSL/TLS certificates expiry dates. Both domain monitoring and SSL monitoring instruments are operating alike and have the same configuration, which includes:

  • Sending renewal notifications 30, 7, and 1 days prior to certificate expiration.
  • Sending instant reports when security certificate is becoming “off”.
  • Reporting daily about the necessity to renew the SSL/TLS certificates.
  • Selecting groups of contacts who can be informed in case of a crisis/emergency.

With activating the two monitoring functions in the Business or Enterprise packages, or in a trial mode, you’ll be always aware of the certificate or domain expiry dates. Or at least, in case of unintentional domain losses, you will be eager to know the reason when, why and how it has happened and sort out the problem.

HostTracker is client-focused

That’s why one of our founding principles as a company included remaining flexible and adaptable, as well as open to improving our service. As the technology world changes, we’ll be ready to make quick, minute adjustments, add new tools and implement new features to improve our product.

Many of our features and enhancements are available online and have been minted due to the customer requests. Therefore, we are looking forward to hearing your feedbacks, suggestions and new creative ideas.

What could we check by using the cloud services? Part 2

  In the beginning, HostTracker company was founded on the basis of a simple website to provide free customer services. Though, a few years later, this startup developed a wide variety of tools serving to solve various problems, including different network issues. In a series of publications, we have decided to describe thoroughly all the features of our service, also to share our experience in the development of such projects with you and to mention interesting challenges that we faced. 

In the beginning, HostTracker company was founded on the basis of a simple website to provide free customer services. Though, a few years later, this startup developed a wide variety of tools serving to solve various problems, including different network issues. In a series of publications, we have decided to describe thoroughly all the features of our service, also to share our experience in the development of such projects with you and to mention interesting challenges that we faced. Moreover, for those seeking an example of how to sell something that had been made for themselves, our experience would be useful, as most of our features were developed due to our personal needs.

In the previous part of the review we have talked about the history of the service and the most basic functions - regular inspection of sites and servers, and what is more, notification of their efficiency. Before starting to describe more advanced features, we should write where do all these ideas come from and how to prioritize them. One of the key secrets often used by entrepreneurs is to follow the statement: all people are unique. All customers’ requests are unique, so you have to learn how to deal with them. Therefore the IT sector is utterly susceptible to this factor, as a great number of customers have profound knowledge and diverse experience. Nevertheless, part of the problems can be solved with available resources. However, the main feature of our work is that, frequently, we have to evolve something. Most of the HostTracker’s functions were developed or adapted due to the conveniences and needs of the particular people. We are also a part of that people, as having rather large infrastructure, and also need to have everything work properly. Therefore, we ourselves are the most picky client.


Precious little things

It worth noting, that in addition to different regular checks, there are other useful tools. They include monitoring of the domain and SSL certificate expiration time. This seems to be negligible, but could bring a lot of unexpected inconveniences to work. These functions appeared in HostTracker, when one of our personal domains had expired. Moreover, large companies also frequently face these problems, as the prolongation of the domain /certificate expiration time depends on the unreliable human factor. Therefore, a notification that the domain should be prolongated, is stored not only within spam folder (already overflowed with continuous marketing messages from your hosting company), but also to the folder with the data of website downs. As well as, the SMS notification capability still exists. That’s why these features are being so handy.

Another interesting feature is the domain check to see if they are blacklisted in DNS-based lists. These lists are independent and are generated separately using different algorithms. What is more, they were mainly created for filtering of the suspicious entities. Each administrator can configure own web server in different ways, for example, not to receive messages from the servers from a specific list. It helps fight off spam, malware spread, DDoS attacks and other problems. But all of these lists have their own algorithms, and there is no guarantee that in the result of any coincidences your website wouldn’t appear in any of these blacklists. Moreover, according to the statistics, this is happening on a regular basis with the most innocent sites. For example, no one can guarantee that a hacker wouldn’t use your nearby IP for different spam attacks. In this situation, the entire range of IPs would be considered as unreliable. What are the consequences of that?  Your messages wouldn’t be delivered to customers, the site wouldn’t be so easily found in search system and so on. Furthermore, you will find out this problem when the changes become critical or even irrevocable. Therefore, the monitoring and notification of DNSBL are also essential.

The content check

Here is a good example of how the usage of functions may exceed developers expectations. We have mentioned about several such cases earlier. Actually, nowadays a lot of things have a web interface whilst for others – it could be easily created, if needed. Therefore, it was developed not only the check function of whether the page was loaded completely using simple parsing, but also another mind-boggling things of this check. Adapting to different customer requests, this feature has become very flexible. It may look for one or plenty of words from the list at once. Moreover, it may detect the emergence of certain phrases. This feature may also raise as an error the whole line that contains the keyword. For instance, if there is a kind of server-status page (“Server 1 OK” etc.) and it shows “Error”, then the message will be “1 Server Error”.  In this case, all diagnostic is already done, and you can start troubleshooting immediately.

What if it happens, that the server should be down?

In addition to the notification of the failures of the sites, HostTracker provides another important function – gathers statistics of each examined site. When the various buttons on the sites were popular – HostTracker’s button also often appeared with the figures of website attendance, the weather forecasts and other things like that. Now it is possible to use a widget, but still the button is also available for retro fans. In addition, statistics is very important for managers. They constantly want to know whether the website and administration of it are working properly. Therefore, there is another useful function - the maintenance planning. Even the most stable sites and servers must be updated or rebooted from time to time. At the same time, it’s not the desired to lose so-called “9s” in terms of uptime. Planning of the maintenance let us achieve two goals (together or separately). This includes: not to send error notifications and not to record errors to the statistics during a specific span of time. Of course, it seems to be a kind of cheating, but outlined maintenances are justified, especially in excluded time. In addition to this, different verifications have being done and written to the log during maintenances. It can be useful for webmasters and administrators, as log let determine exactly the duration of updating or restarting processes, any occurred errors, other breakages etc. Moreover, thanks to that, the whole process of error emergence could be tracked: from the stage when the server wouldn’t be available for some time to the stage when the application would return an error.

Maintenance can be scheduled as a one-time job or on a regular basis. For example, if the backup is done every night, or a new release - every Thursday. The only condition is that the maintenance schedule should be made up at least 12 hours prior to the site/server nearest suspension period of time. This is done to ensure that all maintenances won’t be responsible for any pity unexpectancies, and statistics provided by HostTracker will be trustful.

A kind of an epilogue

We are frequently asked why are we doing that. The same things can be done without HostTracker’s help.  And you know what - definetely, they can. Especially, if you need only one tool. Many people are talking, that the whole Business World is built on human laziness. By solving routine problems, HostTracker provides a slice of work-free and responsibility-free time in the customer’s schedule. Truly, not everyone is able to assemble a car by himself. We look up to the people, who are eager to create something good for personal needs in our field, but most people don’t want to spend their free time for doing something like that.

Additionally, our clients are: non-IT specialists; IT specialists who have to report something to their managers; managers themselves; fans of reliability – they use their own tools and take advantages of someone else’s; and many other groups of people.

All in all, we are always looking forward to your comments.
