SQL server monitoring tool: Three good reasons to go with PRTG
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.
SQL Server monitoring: The right PRTG sensors for the various database systems
MySQL is an open-source database management system that runs on almost all platforms. Keep a constant eye on performance with our MySQL monitoring tool. Monitor the reachability and response times of your databases. Learn more about MySQL monitoring here.
The right sensors for monitoring MySQL:
Among other things, the MySQL v2 Sensor monitors the response time of an entire request as well as the response time of an individually defined query.
SQL Server is a data platform from Microsoft. It is a relational database management system and it is touted as an intelligent database that increases the execution speed of database operations and optimizes the processing of queries.
Sensors for monitoring SQL Server:
Among other things, the Microsoft SQL v2 Sensor monitors the response time of an entire request as well as the response time of an individually defined query. PRTG also comes with WMI Microsoft SQL Server sensors that measure the performance of the database. The sensors are available for several versions of Microsoft SQL, including 2012, 2014, 2016, 2017 and 2019.

PostgreSQL is a free, object-relational database management system. PostgreSQL is developed by an open source community and complies as much as possible with the SQL standard. It also has its own specific extensions, which makes it popular among system administrators and developers.
Sensor for monitoring PostgreSQL:
Among other things, the PostgreSQL Sensor monitors the response time of an entire request as well as the response time of an individually defined query.
Along with Microsoft and IBM, Oracle has one of the leading relational database management systems (RDBMS). Oracle SQL does not fully comply with the SQL standard, partly because its first versions were released before SQL was formalized by the American National Standards Institute (ANSI).
Our sensors for monitoring Oracle SQL:
Among other things, the Oracle SQL v2 Sensor monitors the response time of an entire request as well as the response time of an individually defined query.

Other SQL database systems
Do you use another SQL-based database system? Our ADO SQL v2 Sensor monitors any data source made available via OLE DB or ODBC. As a result, you can also use it to monitor your cloud database when other sensors are inappropriate for doing so.
How PRTG defines sensors
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.
One of the 500,000 PRTG customers: the Vienna Music Association
“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.
PRTG lets you keep an eye on your SQL databases – even on the go
PRTG is set up in a matter of minutes and can be used on a wide variety of mobile devices.
Switching to PRTG safe and easy
There are many monitoring tools on the market. PRTG has the following advantages:
No extra charges
A license will enable you to experience PRTG in its entirety. You'll get every sensor, as well as the notification system. We offer the utmost in transparency during the purchasing process. The free trial version offers you the ability to try all the sensors PRTG has to offer.
Ease of use
Open-source tools like Nagios have certain advantages. But they also come with the drawback that you have to develop a great deal on your own if you hope to enjoy sophisticated monitoring. PRTG is a comprehensive, professional solution with speedy support
Many administrators use a variety of different monitoring tools for special situations. Managing such a combination of tools takes time and energy. And that translates into countless working hours which could be spent more efficiently. Furthermore, you usually don’t get a concise overview.
“The greatest advantage of PRTG? You get to rest easy.“
Steffen Ille, Bauhaus-University of Weimar, Germany
3 examples: Detailed SQL server monitoring with PRTG
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.
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
Find out more about setting up a database monitoring scenario with SQL server sensors in our online manual.
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 ', ')
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
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.
PRTG offers a flexible licensing model for both SQL server monitoring and general network monitoring. Get started with our free version, then customize your license to meet your own specific needs.
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
SQL Server performance monitoring: The values to consider
Overall performance: Total response time
In PRTG, an SQL sensor displays the total response time (execution time) of a request, i.e. the time required to establish the connection, execute the query, deliver the query, and close the connection. SQL Server performance is displayed in milliseconds (ms). If a threshold value is exceeded, you’ll be notified at once.
Query performance: Response time of a single request
In PRTG, an SQL sensor displays the response time of an individually defined query. This is also displayed in milliseconds. Here too, you will define the threshold value that triggers the PRTG alarm. The execution depends, among other things, on how well the query is written.
PRTG comes with WMI sensors that can be used to check the load of your database. These sensors display the total number of connections, the total number of logins/logouts per second, and statistics on memory, access methods, and much more.
Hardware also plays a role in the performance of your SQL Server. In addition to the database, you should therefore always monitor the CPU. By doing so, you can keep a constant eye on the load of your CPU as well as its temperature.
RAM overloads can also cause SQL databases to malfunction and crash. PRTG monitors the RAM of hardware in Windows, Linux, and Unix systems.
