7 Best Database Performance Analysis Tools

Organizations of all sizes have come to rely more and more on databases. With the Big Data trend, it seems like data has become the most important asset of many businesses. And where is that data stored? In databases, of course. This makes the databases—the actual hardware and software that handles the storage, organization, and retrieval of that data—a critical component of many companies. Databases are so critical that making sure their performance is optimal is consequently just as critical. Like many other network and system administration tasks, analyzing database could be done manually but you’ll often be best served by using proper tools. Today, we’re reviewing the best Database Performance Analysis tools.

The database market is large but there are only a handful of major players sharing the bulk of it. We’ll start off our exploration by having a look at databases and the main players. Then, we’ll discuss the performance analysis of databases, what it is and why it’s so important. Finally, we’ll dig into the core of the subject with a review of some of the best tools available for database performance analysis and monitoring.

About Databases

In its simplest expression, a database is a data structure that stores organized information. Data in a database is stored in tables where each row represent one item of data and each column is a piece of information about this item. For example, an address book could be stored in a database where each entry would be a line and where there would be columns for the last name, first name, address, street, city, state, country, etc.

Database systems—also referred to as relational database managers—offer several ways to manipulate that data. Several tables could be joined, data can be indexed for faster retrieval or manipulated in several different ways. Explaining databases would take a whole book. In fact, hundreds of books have been written on the subject. For the purpose of our discussion, the important thing to realize is that databases are quite complex pieces of software. Due in part to that complexity, many factors can affect their performance.

The database market is huge with many vendors offering competing products. However, a few suppliers share the bulk of the market. At the top is Microsoft with its SQL server. Other major players in the commercial database arena are Oracle and IBM with its DB2 database. There are also several free offerings that have enjoyed a growing popularity over the years. One of the most common is called MySQL and it is the database behind many websites. Another free product called PostgreSQL is also very popular.

The Need For Database Performance Analysis

Analyzing database servers’ performance and monitoring their uptime and other operational parameters is one of the most important tasks of network, system, and/or database administrators. It will help keep your database server software running smoothly and efficiently. Done properly—using the appropriate tools—it can prove to be beneficial to not only your server hardware and software but, more importantly, to your end users’ experience.

Many different issues can plague database servers and adversely affect their performance. Among them, here are a few of the most common:

  • Database Size – As the size of a database grows, the server will need more memory and CPU to read and process data from the tables. Increasing the size of an existing table can, for instance, cause a noticeable impact of server performance.
  • Query Structure – Queries are the commands given to the database to fetch some specific data. The more complex a query is, the bigger its impact on database performance. Identifying the most taxing queries on the database server is crucial to managing servers performance. Once the queries that are taking up the most resources are identified, efforts can be put into reducing their load on server cycles and memory usage. Also, finding out which application is causing these expensive queries on your database can help you diagnose the underlying issues behind these queries and fix them quickly and efficiently. Monitoring queries will help you identify which host application is causing issues and potentially help you diagnose other applications issues as well.
  • Index Fragmentation – Data stored in databases is indexed to make searching the database and retrieving data faster and more efficient. Although Proper indexing will help search and retrieve data faster, when data is modified, deleted or removed, the indexed content gets scattered and the database becomes fragmented which could result in performance degradation.
  • Hardware Performance – Hardware performance of the server running the database can also have a bit impact of database performance. Memory, Cache and paging should be monitored in real-time to ensure your database server software is performing optimally and not experiencing bottlenecks or slowdowns.

Our Top Database Performance Analysis Tools

Just as there are many suppliers of database software, the vendors of database performance analysis tools abound. Some refer to it as analysis, others refer to it as monitoring. They all share one common goal, ensuring that your databases are running smoothly and performing at their peak. This list is far from exhaustive and there could likely be a few dozen more products that are just as good as those reviewed here. However, since no one would read through 25 reviews of similar products, we’ve limited ourselves to the seven best tools we could find.
