The more users come online, the more you’ll need to fine-tune your databases. If you want to know what to adjust, you’ll need to regularly monitor it, and that requires coming up with a plan. In this AppOptics APM blog you can find a guide on troubleshooting MySQL performance issues, and in this article, we’ll look at why you need to create a monitoring plan and what it should include.
Why You Need a Monitoring Plan
Using MySQL monitoring software is critical to keep your applications and databases running well since MySQL is backed by a database. Creating a monitoring plan has several advantages, including:
- Security: A well thought out plan allows you to ensure that you have applied enough security measures.
- Growth: The right plan leaves room for growth. You can determine the requirements that traffic and users place on the database. Remember, the needs might evolve faster than you think.
- Performance: One of the most critical things to monitor is the performance of the database. Keeping an eye on things allows you to detect issues before they become major problems or cause a catastrophe.
Looking at the performance metrics not only helps you avoid catastrophic incidents, but it also allows you to decide if you need to implement a performance increase. For example, if you keep track of the time each query execution took, you might be able to find SQL statements that are less than optimal. Then you can look for ways of improving them.
How Often Should You Monitor?
When deciding how often to monitor your application, ask yourself how critical it is. A good rule of thumb is that if a failure will cause a serious impact, you’ll need to keep an eye on things at all times. The good news is that by using the right tools, you can reduce the need to constantly check the performance. Create alerts, so you only have to look at your dashboard each week.
It’s best to use special tools to look at the metrics. They should offer alerts in real-time, particularly if it is critical. That’s also true for ones that contain sensitive information that hackers might try to steal. By taking preventative measures now, you can keep your information safe, even if you aren’t able to respond to an attack right away.
The Metrics to Look at
You’ll also need to create a plan for monitoring resources, such as network components, hardware, software, and anything else your database needs to perform well. Resources such as database waits and query caches are higher level. On the other hand, memory, network interfaces, and CPU are lower level. These things allow you to get a more complete picture of the state of your database. If you have issues, that information is helpful in troubleshooting MySQL performance issues to ensure maximum efficiency.
You’ll also want to look at work metrics, which show the useful output of the database. There are a few subcategories to consider. For instance, you’ll want to look at the number of queries that were done successfully. You should also check the throughput regularly. That refers to how much work your system is doing for each unit of time. That might include the number of queries or transactions each second.
The performance measures how efficiently the database is doing its job. Latency is a common metric for measuring performance, and that shows how much time a unit of work takes to complete. On the other hand, you’ll also want to look at the number of erroneous results. That might be shown as the number of errors for each unit of time. These metrics might be measured separately if there is more than one potential error source.
