SQL server monitoring tool:
Three good reasons to go with PRTG


Concise overview

Concise overview

PRTG measures the time an SQL query needs for its entire request, including the establishment of the connection, the execution of the query, the handling of the transaction, and the termination of the connection.

The execution time appears immediately on your PRTG dashboard. You can also monitor and process your query's return values.

Easy setup

PRTG comes with preconfigured sensors for all major databases, such as Microsoft SQL and Oracle SQL, which are often used by larger companies, and MySQL and PostgreSQL.

Overall solution

PRTG lets you monitor your entire network. Serversrouters, switches. You get one centralized monitoring tool for everything. If the problem lies somewhere other than in the SQL database like in the data center, you'll be notified at once.

PRTG sensors

iWhat is a sensor?

In PRTG, “Sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.

Monitoring SQL servers with PRTG is simple and convenient. To do so, PRTG provides a selection of preconfigured sensors.

  • Oracle SQL: Oracle is used mostly by larger companies. For Oracle, PRTG features the Oracle SQL v2 Sensor.
  • Microsoft SQL: Microsoft's database solution is also used often, both by corporate groups and medium-sized companies. For Microsoft SQL, PRTG offers the Microsoft SQL v2 Sensor.
  • MySQL: MySQL, an open-source application, is used by a multitude of websites, as well as by small and medium-sized companies. For MySQL, use the MySQL v2 Sensor.
  • PostgreSQL: PostgreSQL is also an open-source database system. Use the PRTG PostgreSQL Sensor to monitor a system of this kind.
  • More databases: If you use a database that is not listed above, give our ADO SQL v2 Sensor a try. This sensor can monitor any data source made available via OLE DB or ODBC. That means you can also use it to monitor your cloud database if other sensor types are inappropriate for doing so.

“We were especially worried about the functioning of our online tickets sales system, which thanks to PRTG runs like a charm. In particular, now we are much better prepared for peak hours. And even when bottlenecks arise, the monitoring software shows us exactly where the problem lies so we can take action immediately.”

Peter Hamm, Vienna Music Association IT Director.

Over 800 sensors are used to monitor the software and hardware in this famous concert hall. Online ticket sales, tickets, and appointments are stored in an SQL database.

An introduction to SQL monitoring with PRTG



3 examples:
Detailed SQL server monitoring with PRTG

Ticket system

Ticket system

A company uses a ticket system to process orders. During peak hours, several orders arrive at the same time. PRTG quickly sees that the ticket system is overloading and sounds the alarm. Designated workers are informed by way of customizable notifications, and can quickly take action before the system crashes.

Online store

Online store

Most online stores have a direct link to their warehouse management systems. As sales increase, a company’s stock decreases. PRTG promptly informs designated workers so they can order new goods. Even suppliers can be informed via the PRTG notification system.



How many visitors are currently on your website? How much was generated today in sales? How high are your current online advertising costs? PRTG provides easy-to-understand visuals on this and other data, data which, for example, can be displayed on a screen during a company meeting.

Requirements for SQL monitoring

SQL Server Monitoring with PRTG can be used with the following SQL server versions:

  • MS SQL: Microsoft SQL Server 2005 or later
  • Oracle: Oracle 10.2 or later
  • MySQL: MySQL server 5.0 or later
  • PostgreSQL: PostgreSQL 7 or later

SQL monitoring: definition, examples, uses, costs


SQL (structured query language) is a database language. Queries are performed with SQL to process database information. Several different manufacturers, including Oracle and Microsoft, use SQL for their databases.


1. You can execute a query with SQL sensors to extract and monitor the following information from your online store's database: number of one-off orders, total number of orders, average order value, and names of customers. 

SELECT count(idorder), sum(value), avg(value), GROUP_CONCAT(customer SEPARATOR ', ')
from test.order


For more detailed information on this example, please see the following post in our knowledge base: https://kb.paessler.com/en/topic/70618

2. Since SQL sensors only display strings and are unable to monitor them directly, in this article we describe how you can send an SQL query and still obtain a sensor status that is based on strings. 

Assume you request the "emotional state" of your colleagues, a request that returns strings: 



Rebuild the query so the status is mapped according to integer values: 

        WHEN [EmotionalState] = 'Good' THEN 1
        WHEN [EmotionalState] = 'Sad' THEN 2
        WHEN [EmotionalState] = 'Angry' THEN 3
        ELSE 0
    END as EmotionalState


Now all you have to do is define the corresponding lookups and you will already get a sensor status that is based on strings.



It is highly recommended that you use professional monitoring to monitor your SQL server or SQL databases. Complex SQL queries can have negative effects on database performance. PRTG allows you to monitor and optimize SQL performance. The results: increased customer satisfaction and employee productivity. With the right SQL statement, you can also keep an eye on the size of log tables. You will immediately notice if there is a sudden jump in the number of log entries, which may be a sign of some major problems in your database.

Practical tip: “Hey Stephan, do you have any tips for VoIP monitoring?”

“To simulate a telephone that uses the same network as your real IP telephone, simply set up our QoS Reflector Script on a Raspberry Pi and connect the latter to the desired point on the network. By doing so, you can guarantee that you are measuring the right network path with our QoS Round Trip Sensor. This is important because VoIP traffic is usually treated with priority.”

Stephan Linke, technical support at Paessler AG
