No matter the cause, having monitoring tools at our disposal significantly cuts down on MTTR and getting the system back to a healthy state. If, on the other hand, the database was healthy, we knew to look elsewhere. If the database was unhealthy, my team knew that was where we needed to focus our efforts. When monitoring is available though, it’s easy to determine if the issue originates in the database. On many occasions, the service my team and I were working on began throwing 5XX response codes. In such cases, MySQL charts help pinpoint the cause by revealing when the issue appeared. For example, your services may be leaking database connections. Since databases are often the center of most systems, MySQL frequently ends up being a bottleneck for other services. This is particularly important with MySQL. A good monitoring tool will also send alerts when metrics deviate from a steady state so that you can quickly intervene and avoid potential outages or other customer-impacting issues. MySQL monitoring tools achieve this through low-level system metrics that offer an overview of your deployment. Not only do metrics allow you to determine whether your MySQL database is healthy, they also help prevent performance issues. It’s an inexpensive solution that delivers companies great ROI. If your customer base is growing or you’re experiencing frequent performance issues with your MySQL deployment, you need a database monitoring tool. In this blog post I’ll review some of the best MySQL monitoring tools available that can help measure and improve database performance. But choosing a database monitoring solution can be tough due to the vast number of solutions available, each with their own pros and cons. A good monitoring tool alerts on issues before they impact end users and helps reduce the MTTR of incidents when they do occur.

The target is available, now I can use most of the EM12c features to monitor my MySQL environment. The target name is automatically set to hostname:mysqlport:Īs all discovered targets, I need to promote it to have it available for monitoring with EM12c: Tada! at the next discovery, I have my target available:

So it is necessary to activate it and deactivate the discovery modules I do not need:

What went wrong?Įach agent has a default list of “discovery modules” used for the discovery, but by default the MySQL one is not enabled after I install the plugin: Now I can run the target discovery on the agent:īut the discovery does not find my MySQL targets. I may select all agents as well, but it’s better to be neat…Īgain, there are prerequisite checks and confirmations: I must select one by one the agents that run on the hosts where I have MySQL running. Now I can see that the plugin is correctly deployed on the OMSes, I can do the same for the agents: If everything went OK, I’m able to check the status of the deployment: Specify the credentials for the Management Repository: Verify the prerequisites check (here I have one column per OMS): The agent has been downloaded, but in order to make it available on the targets, I first need to deploy it on the management servers (2 OMSes in my case): Setup -> Extensibility -> Self-Update -> Plugins: I can verify that you have the last version by going to

The first step is to download the last version of plugin for MySQL. So I’ve upgraded (a while ago) my customer’s EM12c to 12.1.0.5. Luckily, Oracle has officially released a MySQL plugin for EM12c, provided that the EM is at least in version 12.1.0.4. What makes EM12c a GREAT product comparing to MEM, are many features like blackouts, a usable command line interface ( emcli), integrated reporting, scheduler, automatic groups… the list would be just huge. In MEM all the tables are crypted and it is not possible to list, for example, all the targets monitored, nor it is possible via API or REST web services because MEM 3.0 lacks these features. In particular, MEM 3.0 does not have a usable database. I have blogged in the past about MySQL Enterprise Monitor 3.0 and I was quite happy at the very beginning, but after a while I have to admit that I was missing many of the Oracle Enterprise Manager 12c features.
