Best Oracle Monitoring Tools

Oracle was one of the first developers of relational database management systems and produced the first commercial SQL implementation. So, Oracle is very widely implemented because it has been in the database supply industry longer than any other company.

Here is our list of the best Oracle monitoring tools:

  1. Paessler PRTG EDITOR’S CHOICE This package is a bundle of monitors that build up into a full-stack observability service. The platform includes a sensor for Oracle database monitoring and has units to track the performance of other DBMSs as well, including SQL Server, MySQL, MariaDB, and PostgreSQL.

  9. dbWatch Unified monitoring of all databases on a site regardless of DBMS vendor.

Oracle has developed many front-end products and refined its database management software, deepening its expertise in the field.

However, despite its technical excellence, a typical Oracle database needs constant adjustments to its resource utilization to ensure that it doesn’t hit capacity limits.

Oracle optimization and daily administration

Databases continue to grow through an accumulation of transactions over time. This inevitable expansion can require tables to be reanalyzed for efficiency, SQL queries to be optimized, and structures to be assessed and adapted. All of these tasks can be performed more efficiently with the support of automated tools.

Along with the optimization requirements of Oracle databases, a database administrator (DBA) has to pay attention to daily tasks, such as backing up the system, managing user accounts, and coordinating the development and live instances. Data security has become a major issue in recent years, and access logging has become a fundamental requirement for any RDBMS.

The best Oracle monitoring tools

There are two categories of tools that any DBA needs in order to perform the job well. These are monitoring systems and management tools. One makes sure nothing goes wrong and the other makes it possible to get the database running better. Very good tools combine both monitoring and management functions.

Our methodology for selecting this list of Oracle monitoring tools

We reviewed the market for Oracle monitoring software and analyzed the options based on the following criteria:

  • An SQL query optimizer with an editor to guide the creation of new queries
  • A database instance assessor that can recommend better indexing
  • An interface that can provide a single front-end to many database instances
  • Server resource usage monitoring
  • Database instance performance monitoring
  • A free trial period that allows a risk-free assessment
  • Value for money with useful tools offered at a suitable price

1. Paessler PRTG (FREE TRIAL)

Paessler PRTG

Paessler PRTG offers Oracle monitoring together with performance tracking for many other technologies. It provides full-stack observability through its list of sensors that watch networks, servers, and applications. By activating the right combination of sensors, you can monitor your Oracle database instances in the context of all the systems that access them and all of the services that support them.

Key Features: 

  • Tools to monitor many DBMSs: Includes Oracle, SQL Server, MySQL, and PostgreSQL monitoring sensors
  • Tracking for database metrics: Looks at the size of a tablespace, its growth rate, and resource usage
  • Customizable dashboard: Decide which technologies to monitor and adjust the layout of each screen
  • A universal SQL query tool: Set up your own queries on system tables
  • Full-stack observability: Monitor networks, servers, and applications

Why do we recommend it?

Paessler PRTG is a monitoring package that offers the buyer a choice of sensors rather than presenting a one-size-fits-all service. The bundle of tools in the PRTG system includes a specific Oracle database monitor and options to generate customized queries that can be run as performance monitors.

The full package that is available to every buyer is much larger than any company will ever need because it includes specialized monitoring services that map to specific products, such as VMware, Oracle databases, or Apache Web Server. On acquiring the bundle, an administrator’s first task is to work through the list of available sensors and decide which to activate.

Once a sensor is live, it can be adjusted. For example, you can simplify the Oracle monitoring tool by deciding which of the available metrics to show in the Oracle monitoring screen in the PRTG dashboard. You can also decide how data should be shown – data tables, charts, or dials.

Who is it recommended for?

The PRTG package is suitable for all sizes of businesses. If you only activate 100 sensors, you never have to pay for the package – small businesses will like that. The Oracle monitoring system is effective as part of a systemwide monitoring package and won’t appeal to DBAs who also need database management tools.

Pros:

  • Hybrid monitoring tool: Can monitor systems that are hosted on the cloud as well as on-premises services
  • Simultaneous monitoring: Track the performance of many technologies at the same time
  • Free edition: You don’t have to pay if you only activate 100 sensors
  • Customizable queries: Set up queries on system tables and run them as monitoring cycles
  • Performance alerts: Get warnings if resources run short or response times lengthen

Cons:

  • Integration Effort Required: Users need to configure and link different monitors to achieve a comprehensive monitoring setup.

Paessler provides PRTG as a SaaS platform or as a software package for Windows Server. You can access a 30-day free trial of PRTG with all of the sensors activated.

EDITOR'S CHOICE

Paessler PRTG is our top pick for an Oracle monitoring tool because this bundle of monitoring tools includes Oracle database monitoring along with sensors for all your other IT assets. So, you get full-stack observability with this purchase, not just a database monitor. The system allows you to correlate resource usage between your database instances and supporting servers. The package includes monitoring tools for SQL Server, MySQL, MariaDB, and PostgreSQL databases as well as those of Oracle. You can add to the pre-written probes by setting up your own queries on system tables and adding them to the regular monitoring cycle. The screens of the dashboard are also customizable, making the whole PRTG system a very flexible service.

Choosing an Oracle monitoring tool

Over the decades, the job of a DBA has transformed from being a relatively simple job into a departmental responsibility. The requirements of database management now occupy a team. The risk of failure is high, with the threat of legal action for data loss or corruption and a high probability of business failure should a critical disaster hit the database.

Oracle databases have become central to the operations of the businesses that use them and even a temporary outage could cause the company to fail. Automated database monitoring tools ensure that support staff gets alerted to potential problems before they become critical. Database management and analysis software can help a small team excel at making system performance better.

Database tools are worth the investment because they improve the efficiency of the Oracle database, increasing value for money, and they minimalize the risk of failure.

Oracle Monitoring FAQs:

How do I monitor an Oracle database?

Oracle provides a monitoring service in the graphical user interface for the DBA tools. This lets you see session information, records of locks and waits, I/O activity, top SQL factors, and details on SQL statements that take a long time to complete. Alternatively, you can buy a database performance monitoring tool.

Is MySQL the same as Oracle?

MySQL was created by Swedish company MySQL AB, which was bought by Sun Microsystems in 2008. Oracle bought Sun in 2010, so MySQL is now owned by Oracle. Oracle invented SQL and this is now the industry standard for managing and accessing data in relational databases. The MySQL version of SQL is a little different from that implemented by Oracle, which is called SQLPlus.
