Database Monitoring
Database monitoring Database monitoring - DB check for access and regular execution of the specified query.

Database monitoring feature allows to run a query during every check and react in the appropriate way on the result. Also, it is possible to check just possibility to connect to DB - by ignoring the query field. To set the monitoring, fill the connection data: DB server address, port, database name, login and password of a user for connection. We strongly recommend to create the new user with limited rights. However, do not forget to provide him enough rights for performing the supposed actions. Also, it is necessary to add HostTracker servers addresses, to the whitelists on firewall or other blocking software, to allow the access. The addresses are permanent, and are listed on the same form.

Create ContentCheck Task

There could be arbitrary query - SELECT, UPDATE, DELETE, INSERT, execution of stored procedures (like scheduler), results comparison, logical operations. The only restriction is execution time - it should not take longer than 30 seconds. Otherwise, the timeout error will be reported.

It is recommended to create the queries which display the necessary value in the first row of the first column. This result can be analysed. For UPDATE, INSERT, DELETE queries the number of affected rows is analysed. There are different ways to analyse the resulted value by comparison with specific preset - equal/not equal/higher/lower/in range. In case the condition is not satisfied, no connection to DB, query timeout - the error is reported.

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.

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, Viber, 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.

"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."
