One of the key features of Query Monitor is its comprehensive statistical information regarding website performance. It provides detailed reports regarding the overall loading time of a website, the average size of the pages, and other details regarding the various queries being run on the website. These detailed reports provide users with a much better understanding of their website’s performance and can be used to identify any potential problems that could be causing slowdowns.

Query Monitor also includes a comprehensive debugging feature that allows developers to easily identify and analyze any performance issues with their website. This feature includes a comprehensive code traceback feature that can be used to trace all the code used in a given query request. This can allow developers to quickly identify any areas of code that are inefficient or unoptimized, allowing them to quickly improve the performance of their website.

In addition, Query Monitor also includes a powerful query monitor feature that allows developers to easily monitor the queries that are running on their website. This feature provides a detailed breakdown of each query type being run on the website such as those related to content or databases. This can help developers quickly identify any queries that could be causing performance issues.

Pros of Using Query Monitor

Increased Debugging Capabilities: Query Monitor allows users to debug error messages, warnings, and other faults in their WordPress site. Through the plugin users can identify problematic PHP errors, slow database queries, and over 130 other types of actions that are taking place on the web page. This increased visibility helps users to identify and address potential issues before they cause bigger problems, reducing debugging time to a minimum.

Increased Performance: High performance websites are dependent on sparing and efficient use of resources. Query Monitor provides users with precise control over their system resources, enabling them to optimize database queries and identify request-intensive behaviors that might be slowing down their web page. This helps to ensure users are only using the necessary resources, and eliminates wasteful, over-complicated scripts.

Robust Action Logging: Query Monitor provides a powerful logging engine that enables users to track deeper into an issue. This feature makes it easier to troubleshoot and find the root cause of errors, as well as how they are related to other actions on the website. It also offers an in-depth timeline with detailed information that clearly shows the action or process that led to the issue.

Enhanced Search Tools: Query Monitor offers powerful, advanced search tools that allow users to quickly and accurately find the cause of any issue. This can be used to find a particular component or file, as well as drill down into particular pieces of code to find related errors or warnings. It also provides users with an easy to use filtering system that enables them to group and prioritize errors and warnings for easier troubleshooting.

Real-Time Performance Reports: Query Monitor provides a clear real-time performance report that gives users a bird's eye view of the performance of their WordPress website. This report includes information such as the current page's resource usage, average page loading times, and processing time of database queries. This allows users to quickly identify any areas of inefficiency and take corrective steps to reduce website loading times.

Cons of Using Query Monitor

Slow Performance: Query Monitor requires that certain PHP processes and scripts be enabled, which in turn can affect the performance of the website. This can be difficult to manage in cases where the site has a large number of visitors. Additionally, if certain plugins are required to be enabled for Query Monitor to work properly, this can also have a negative effect on performance. This means that while Query Monitor is great for troubleshooting and debugging certain issues, it can also cause performance issues.

Potential Conflicts: Query Monitor is one of many WordPress plugins, and with so many plugin operations going on there is the chance for potential conflicts. If these conflicts are not caught and resolved, the website can potentially encounter issues which are difficult to diagnose precisely because of the Query Monitor-related conflicts. This is why careful monitoring and management of any potential conflicts is essential for using Query Monitor safely and effectively.

Inaccurate Data: The data that Query Monitor provides is only as accurate as the information it is privy to. This means that if certain data is not properly collected by Query Monitor or if there are any errors in the data, then the results gathered can be inaccurate or incomplete. This means that while Query Monitor can provide invaluable insights, users must be aware of any potential discrepancies in the data. This includes potential false positives or false negatives that can arise from Query Monitor.

Better Debugging Tools: There are many WordPress debugging plugins available so users should take some time to compare all the options before settling on a particular tool. In particular, there are other plugins such as Debug Bar that can provide more detailed information than Query Monitor. Furthermore, if you require more in-depth information, then you may want to consider using server-side debugging tools such as XDebug.

Unpredictable Outcomes: With so many settings and triggers, it is difficult to know exactly what will happen when Query Monitor is used. This means that the outcomes of debugging sessions can be unpredictable, as there may be unintended consequences. This is why it is important to have a clear understanding of all the potential settings and triggers available and how they may affect the results.
