Basic Authentication is a form of authentication on a web server for secured areas of a website.
This is performed by the web server and is recognizable by a pop-up window
requiring you to enter your username and password.
A transaction depicts a certain process or user behavior, that is carried out on a website
with the help of a web browser. An example of this would be a newsletter registration form,
signing into a customer area, searching for an article, or even the complete shopping
process in an online store.
With this function, previously defined transactions are monitored by means of an actual
browser (currently Internet Explorer 9), where any user behavior that is possible in the
browser can be depicted and monitored.
In this process cookies, session-stickiness, GET/POST-variables and redirects, and client-side
In the case of an error, screenshots of the browser view are created and made available in
the evaluation, together with the additional error information.
A check is a monitoring option offer by ServerGuard24,
with which you can monitor applications performed on servers.
For this reason, every check has corresponding parameters which serve to configure the monitoring.
A contact is a person notified of errors or OK status.
Checks are assigned to contacts who are notified of the status changes to these checks.
In an UNIX environment, a daemon is a background application that runs
on a server and provides checks and processes set tasks. In Windows the term "service" is used.
ServerGuard24 uses a distribution system with which it checks
the individual checks from several distributed locations. For this, we distributed various measuring points,
that are selected from their locations, so that we can assure sound monitoring even if connection failure along certain routes in the internet should occur.
The quality of the monitoring results is also significantly
improved since in every case an error is verified from 3 different points.
A false alarm is when an alarm is triggered after an incorrect check,
even though there is no error. Reasons for an inaccurate check could be network fluctuation or contact
congestion so that a time out occurs. To prevent this from happening,
ServerGuard24 performs repeat checks.
The monitoring of the individual checks is carried out from various
measuring points. Geographical regions are assigned to these measuring points. This option
is configurable per check. It can therefore be determined from which region this check
should be checked. As a result, it can be guaranteed that the monitoring results are
traced to the exact location as that accessed by the user of a check.
HTTP Push is another notification option. Thereby you can specifiy any script (reachable via HTTP) which
will be called in case of a notification event. When calling this script the notification information will be attached
via POST variables to the request.
The API offers the possibility to access the server and checks
monitoring data with web applications. A parameterized request is sent to our server,
which then sends back the requested information. The interfaces are expanded/broadened
if required and are protected with a key against unauthorized access.
- Current Status: Status information about monitored checks and server
Maintenance interval describes the time in which a server/check is undergoing maintenance.
During this time typical tasks (e.g. reboot, updates ...) are being performed on the server causing it to completely or partially unavailable.
It is therefore helpful to mark these intervals in order to avoid false alarm resulting in notification being sent.
ServerGuard24 employs various measuring points in distributed monitoring.
A measuring point describes a server from which the actual check of the target system is performed.
Location and provider connection are characteristics which are significant for the distributed monitoring system.
This refers to the period of time between two checks.
At the same time it also establishes the longest possible amount of time that an error goes unnoticed.
Notification is the contact information about a status change of a check.
There are two types of notification: via mail and via SMS.
In addition to availability, there is also the possbility to add performance parameters to the evaluation.
This response time for the executed tests is available for the verification being carried out. The parameters, which
can be evaulated additionally, can be found in the detailed description of each check.
The reference check is fixed on the server, which is used as a reference for sending notifications.
Depending on the status it can be used to send messages of other checks.
If the reference defined check is in error, no notification is sent for other checks on the same server.
The PING check is an example of a possible reference check.
After a check has been tagged as in error or down,
ServerGuard24 performs further checks to ensure that it is not a false alarm.
The time distance between these repeat checks is between 30 and 120 seconds depending on the plan.
As a Premium plan user you have the possibility to set the repeat check interval yourself with
the "Alarm after Error of" option.
A notification is only sent however after 3 unsuccessful tests.
If the check is unavailable for more than 2 hours (standard configuration) or is in error,
new notifications are sent out to the appropriate contacts. The goal is to inform you of ongoing errors.
Notification is only sent if you have activated the "repeat" option for the notification for a specific check.
The time interval for the repeat notification can be configured individually in the Premium plan.
This function allows the evaluation of monitored checks to be sent via email. Any given number
of tranmissions can be defined. The transmissions depend on the server/checks, the time frame
(daily, weekly, monthly, quarterly, annually), and the recipients' contacts can be individually configured.
The term server is used to describe computers on which applications are performed.
As soon as these computers are connected to the internet, they can be monitored by ServerGuard24 .
A transaction depicts a certain process or user behavior, that is carried out on a website with the help

Servers transactions make it possible to permanently monitor previously defined transactions. ServerGuard24
is used as a technical solution to this, that simulates GET and POST requests from a user's web browser and
thereby carries out the transaction step while also checking the results.
In this process cookies, session-stickiness, GET/POST-variables and redirects are all supported. In this way,
The most important characteristic of SSL is the encoded transfer of data which enables
the application of various encoding levels. The SSL protocol is based on the TCP/IP-protocol and is therefore
The most common application can be seen in connection with the HTTP protocol and is also known as HTTPS.
This combination allows you to encode data transferred between the visitor's client and your website's
The URL (Uniform Resource Locator) is the exact address of a particular website.
