Databases are extremely critical components of the operations of most online businesses. Database performance issues contribute to almost 50% of the issues in applications. Yet, most businesses give little to no attention into the performance of their database. To help fix this problem, database administrators should use database monitoring tools.
An efficient database monitoring system can help eliminate downtime. It also helps optimize performance and usage. Businesses can avoid losses in revenue and ensure a better user experience.
A database monitoring tool continuously monitors resource usage like CPU, disk space, memory, and I/O capacity. It also continuously tracks database connectivity, performance, and security. The system constantly compares these metrics to historic performance benchmarks. You or your database administrators get an immediate alert if there’s a spike in these metrics. Thus, you can detect and solve issues before they cause any significant damage.
In this guide, you’ll gain a solid understanding of what database monitoring is. We’ll also cover the benefits and some best practices for database monitoring. Finally, we’ll talk about the top five database monitoring tools right now. There’s a special focus on our recommended tool: SolarWinds® Database Performance Monitor.
What Is Database Monitoring?
Database monitoring, as the name suggests, tracks the performance and usage of all the databases in an application. Databases form a vital cog of any information system. They store, query, and update valuable and sensitive business data. Even a tiny vulnerability can cause crippling damage to the entire application.
Thus, the aim of database monitoring is to ensure high performance and highly available application infrastructure. For this reason, there’s constant tracking of production database instances, which you can find in a repository.
It’s also important to monitor key metrics to keep an eye on the availability, performance, and functionality of the database. Some of these metrics include workload, configuration, memory consumption, transaction rate, and user call rate. Moreover, data points such as memory buffers, input/output operations, connections information, threads information, read/write requests, and table locks are also tracked. All these metrics can give you insights into how well the database infrastructure is performing.
What Does a Database Monitoring Tool Do?
A database monitoring tool continuously monitors all these parameters in live production databases. Using past trends, the tools automatically set the benchmarks for these metrics. The database administrating or DevOps team can also set these benchmarks manually.
The monitoring system will constantly compare the live database performance metrics with these benchmarks. Therefore, the database administrator will get an alert if there’s a spike in resource utilization. This will allow administrators to take timely action before vital business processes break down.
The tool also stores these data points. Then it aggregates, sorts, and analyzes the historical data. What’s more, the tool predicts if the current spike is an anomaly, a recent or regular trend, or normal behavior for the current scenario.
The historical data also provides detailed and extensive insights into performance. The reports can help you identify and solve the root causes of these issues, and the comprehensive analysis can help you prevent and combat issues in the future. As a result, the infrastructure will become more robust, and your teams will be able to resolve issues faster.
Effective Database Performance Monitoring With Specialized Tools
A slow database can affect an applications’ health and performance and bring them to a halt. Visibility of database performance metrics is crucial to quickly identify the root cause of the problems and troubleshoot errors. SolarWinds software allows you to monitor and analyze the performance of your database infrastructure. It can allow you to monitor the most important metrics related to the performance of your hardware and its behavior if there’s an increased number of queries or queries with incorrect code design. This applies not only to dedicated servers owned by your organization. It also offers out-of-the-box cloud computing services integrations like AWS EC2 and Azure SQL services.
DPA, DPM, and SQL Sentry offer quick query monitoring of their code and the effect on database performance when queries are received. DPM can be used to check database performance before and after making code changes related to the application, database, or in the design of the queries themselves. DPM is designed to easily detect queries not previously present in the monitoring process. This is very useful in the work of DevOp teams—DPM can help facilitate cooperation between teams.
The Changing Landscape of Database Infrastructure
Modern product development has become more agile. DevOps practices have also evolved, bringing new challenges and needed skillsets for database administrators. As noted in the 2019 IT Trends report from SolarWinds, over half of IT professionals surveyed say the most important technologies for their career development are cloud and/or hybrid IT (67%), big data analytics (48%), and artificial intelligence or AI (48%).
Another new trend is the adoption of cloud infrastructure. The meteoric rise of cloud is no secret. As a result, mixed server estates are becoming mainstream. IT businesses may have a few legacy databases on-premises while other databases are in the cloud. This hybrid server infrastructure may lead to complex database issues. It makes sense for organizations to constantly monitor all databases across the system.
Importance of Database Monitoring Tools
An efficient database monitoring system has multiple benefits. It helps you save on breakdown costs and avoid loss in revenue due to outages. Database administrators should invest in a top database monitoring tool.
Minimize Outages and Slowdowns
Constant monitoring and processing of application performance can help reduce outages and slowdowns. Any threshold violation can trigger alerts and notifications by email or SMS. These alerts can be about high CPU usage, low memory, low disk space, or abnormal network traffic, to help IT teams resolve issues before they cause an outage.
Proactive monitoring is always better than a reactive approach. Without these warning signs, database outages and issues can go unnoticed for a long time. This can lead to a loss in business revenue during this downtime. Constant monitoring can minimize these breakdowns.
Maintain Critical Components
Modern online businesses process vast amounts of critical data, making databases a vital cog in the system. They’re a direct or indirect part of the fundamental processes of a business. Even a minor database performance issue can critically wound the entire operation. Small mistakes can lead to losing valuable data.
Most IT teams don’t focus on these issues—databases are an Achilles’ heel for applications. Monitoring the databases will help protect this critical component.
Identify Problems Faster and More Easily
As mentioned before, modern infrastructure is wide-ranging. Databases may be in the cloud or on-premise. They may also have different tools supporting them. This makes the whole system intricate and complex. Quickly finding and isolating the underlying issue is difficult. In some cases, a minute query error can break the entire system.
Database monitoring helps you measure each of these smaller factors. It also provides continuous visualization of key metrics, so identifying the root cause of issues becomes simpler and much faster.
Resolve Issues Faster
Once you’ve identified an issue, database administrators and managers need to resolve it as fast as possible. Tracking key metrics of database performance will help you resolve issues faster. Database administrators can gain key insights from sophisticated reports based on past behavior data, allowing them to troubleshoot problems much more quickly. This can help reduce downtime due to database errors.
Reduce IT Infrastructure Costs
With faster problem identification and resolution, database administrating teams spend less time and use fewer resources. They have the power to find faster solutions. Moreover, they know about most issues before those issues become major errors. Major errors are costly. Preventing them before they have an adverse effect is cost effective.
Improve User Experience
Slow applications frustrate users. They ruin the online experience. Moreover, database issues and outages can lead to bad user experience. This can even lead to lost customers.
Database monitoring services can minimize these instances. They proactively search and troubleshoot these performance issues. The aim is to detect and resolve any snag. The best systems do this before problems affect the end user. This helps ensure great user experience.
Database monitoring can resolve problems such as slow database response time, load issues, and slow requests. These can drastically hinder optimal application performance. Furthermore, in-depth analysis provides key insights to help you optimize servers for better results.
A better database performance leads to increased business and technology infrastructure efficiency. This also helps your organization improve its return on investment because you can get more output from the same resources.
How to Implement Database Monitoring
An efficient database monitoring system must follow some key actions. However, there’s no “one-size-fits-all” model for this. The needs and characteristics can be very different for different types of applications. However, here are a few general steps required to implement database monitoring.
- Continuous monitoring of defined metrics
- Automatically collect and store resource consumption, availability, and performance metrics
- Analyze and visualize key database and server parameters
- In-depth report generation using historic data to show utilization and capacity trends
- Send alerts in case of unusual behavior of KPIs
- Recommend precise actions to resolve performance issues
- Assess end-user metrics to identify and isolate database issues
- Maintain detailed notes for recurring problems for faster resolution
- Accurately diagnose root causes of issues
Most database monitoring tools today provide these features.
Performance Metrics and KPIs
Database monitoring tools track and analyze performance metrics, but it’s important to define those metrics. DevOps teams and administrators need to know what they’re measuring and why. The tool can present the data but making sense of this data is up to the team.
In this regard, there are a few parameters you’ll need to monitor.
First, you’ll need to track resource consumption. These are mainly infrastructure related, like CPU usage, memory use, storage, and I/O capacity. Some of these KPIs include percentage of CPU time used by the process, I/O wait times, percentage of virtual memory use, memory buffer utilization, connection statistics, active transactions, and deadlock details.
Another set of metrics to track has the aim of optimizing queries. It’s important to monitor the top active slow queries running slower than a certain threshold. The KPIs help identify poor database design, inefficient query plans, unnecessary requests, bloated indexes, or database schema changes. These issues can weigh down the database.
To set performance benchmarks, collect throughput metrics. This signifies the amount of work the database does under normal working conditions. However, the benchmarks should dynamically adjust depending on the situation. Different occasions may represent different workload periods. For example, these benchmark metrics may differ during normal hours, low-traffic time slots, weekend sales events, Black Friday sale events, and other such instances.
