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.

HostTracker — Sites Monitoring Service
Every site owner knows how important it is to have your resource always operative and available for visitors. Periodical site unavailability has a bad influence even at its positions in the search engines (as Google representatives have repeatedly claimed), not to mention the fact that visitors are extremely displeased by such “accidents”...

How to be always aware of how properly your site is operated in real time?

HostTracker is an online website monitoring service, having rich functionality and good feedback of the customers, who are, by the way, more than 25 thousand (including the resources of such companies as Colgate, KasperskyLab, Panasonic etc.).

The job design of this service is the following: at certain specified intervals your websites and servers will be checked for availability and serviceability (the verification is performed from around the world), and in case of any problems you will receive notifications about the problems. In addition, uptime statistics for each site is collected, but it will be discussed later.

A quick site serviceability check may be performed directly from the service main page through typing its address in the upper right window and selecting one of the verification methods:

  • Http – website pages loading check
  • Ping – the server availability check (pinging)
  • Trace – the server availability check (tracing)
  • Port – random server port check

According to the check results a detailed report will be created on a separate page.

To become the HostTracker service client and verify the uptime and serviceability of your resources on a regular basis you need to register in the system and assign the appropriate tasks. Over time detailed statistical reports and visual graphics will be created for each task, greatly facilitating data analysis, outputing them in an understandable representative form.

Site failures and problems may be reported to (at your option):

  • Email as a letter
  • telephone as an SMS or a call
  • Skype or GTalk as a message

At that it is possible to set the notifications delay, their uploading time etc. – the settings are very flexible. By the way now I really miss such functionality at Monitorus, as it sends an SMS immediately when a problem occurs, regardless of the time of day, and as you can imagine, late night may be very fun because of this).

Another useful feature of the HostTracker service is the site content monitoring. You may set a list of the page keywords, at the disappearance of which you will receive the notification. Or vice versa – set a list of words, at the appearance of which you will receive the notification. The first case, for example, is good for paid links on other sites monitoring, and the second – to prevent virus activity in the form of additional code embedding on your website. Say, it is very helpful and very convenient!

Now a few words about the HostTracker site monitoring service rates prices. There are several service plans, differing in the maximum tasks number, check frequency, etc. However, there is also a full-featured trial period of 30 days, as well as the Free tariff, within which you may monitor up to two resources with an interval of 30 minutes. That’s not much of course, but as an option to try out all the features for free, and then decide on the appropriateness of the paid tariff transition, it is just the job. Good luck!

I set my site to be checked every 1 (10, 30 etc) minutes, however I see only 1 record in logs for a day. Why?
Note that adjacent checks with the same result (all show Ok or all fail) stack into a single record in logs by default. Pay attention to columns "Check cnt." and "Interval" in the log. "Check cnt." shows how many checks have been made for the specified interval. It is done to make logs less bulky. However, you may turn on "Full log" option for your tasks - in this case all checks are saved separately. You may select this option while creating or editing a task.
Can I insert a list of sites for monitoring?
While creating a new monitoring task click "Add list" near the URL field. Then insert into the extended field the list of sites, each one from the new line.
How to add more sites for monitoring?
Sign in at www.host-tracker.com and on the main page and click "Add", for web sites click on http. Then fill regular task creation form.
Does HostTracker affect my analytics?
HostTracker does not execute any javascripts while checking your sites. So, if you use external monitoring tool, like Google Analytics, these checks are not counted. However, if you use some internal monitoring system - HostTracker requests will be logged. In this case you may exclude checking servers by IP. List is here.
