Percona Monitoring and Management (PMM) has been on the road for a while now, and it brings exciting new features and improvements. For those who are not familiar with the tool, PMM allows deep insight into the performance of applications and databases. The most crucial highlight: it is 100% open-source. Also, the source code is present on GitHub.

Back to new features and improvements. One of them, that customers were requesting, was the support for LDAP. This feature finally arrived with PMM version 2 thanks to the new version of Grafana, and I intend to demonstrate in …

Percona Monitoring and Management (PMM) is built upon the shoulder of giants like Prometheus and Grafana. And speaking of Grafana, one of the coolest features that come with it is the ability to customize the experience through 3rd party plugins.

Plugins are an easy way to enhance the ability to have specialized graphs. One case that we saw in Managed Services is the ability to have a throughput graph, that shows QPS vs Threads running. This is different in essence of the “default” graphs that show a metric against time (time being the X-axis) since what we wanted is to show queries per second not during a time (that graph already exists) but for specific values of threads.

One way to achieve that is by using a plugin called Plotly …

As Grafana powers our star product – Percona Monitoring and Management (PMM) – we have developed a lot of experience creating Grafana Dashboards over the last few years.   In this article, I will share some of the considerations for designing Grafana Dashboards. As usual, when it comes to questions of design they are quite subjective, and I do not expect you to chose to apply all of them to your dashboards, but I hope they will help you to think through your dashboard design better.

Design Practical Dashboards

Grafana features many panel types, and even more are available as plugins. It may be very attractive to use many of them in your dashboards using many different visualization options. Do not!  Stick to a few data visualization patterns and only add additional visualizations when they provide …

We have been working with PMM for quite a long time, we do most of the performance analysis with PMM for most of our clients. It also provides the flexibility that we have built our own custom dashboard. PMM has many advantages

• Easy to deploy (docker based)
• Flexible
• Customizable
• Query Analytics
• One-stop solution for MySQL,Mongo,ProxySQL & PostgresSQL
• Orchestrator
• Rich and Deep metrics stats

Highly recommended for any production deployments its equivalent to Enterprise-grade monitoring and graphing tool.

Recently we have been working for our client on MySQL Consulting to scale peak sale of the year. Wherein we have deployed PMM to view the performance …

One of the great things about working at Percona is the constant innovation that occurs as a result of a deep level of technical expertise. A more recent conversation about the Information Schema table: innodb_cached_indexes led to the desire to produce this information in an easy to digest and useful format. Enter PMM.

Our goal with creating this dashboard was to help bring further insight into how your MySQL database cache is being used. Why is this important? Data is accessed significantly faster when it is cached, so indexes that are cached will allow for an increase in query performance. Until now there has not been an easy way to see which indexes are cached and which are not. We want to take the …

We are pleased to announce the launch of PMM 2.0.0-alpha2, Percona’s second Alpha release of our long-awaited PMM 2 project! In this release, you’ll find support for MongoDB Metrics and Query Analytics – watch for sharp edges as we expect to find a lot of bugs!  We’ve also expanded our existing support of MySQL from our first Alpha to now include MySQL Slow Log as a data source for Query Analytics, which enhances the Query Detail section to include richer query metadata.

• MongoDB Metrics – You can now launch PMM 2 against MongoDB and gather metrics and query data!
• MongoDB Query Analytics – Data source from MongoDB Profiler is here!
• MySQL Query Analytics
  • Queries source – MySQL Slow Log is here!
  • Sorting and more …

We are pleased to announce the launch of PMM 2.0.0-alpha1, Percona’s first Alpha release of our long-awaited PMM 2 project! We focused exclusively on MySQL support in our first Alpha (because we wanted to show progress sooner rather than later), and you’ll find updated MySQL dashboards along with enhancements to Query Analytics. We’ve also added better visibility regarding which services are registered with PMM Server, the client-side addition of a new agent called pmm-agent, and finally PMM Server is now exposing an API!

• Query Analytics
  • Support for large environments – default view all queries from all instances
  • Filtering – display only the results matching filters – MySQL schema name, MySQL server instance
  • Sorting and more columns – now sort by any …

One of the great things about Percona Monitoring and Management (PMM) is its flexibility. An example of that is how one can go beyond the exporters to collect data. One approach to achieve that is using textfile collectors, as explained in  Extended Metrics for Percona Monitoring and Management without modifying the Code. Another method, which is the subject matter of this post, is to use custom queries.

While working on a customer’s contention issue I wanted to check the behaviour of InnoDB Mutexes over time. Naturally, I went straight to PMM and didn’t find a graph suitable for my needs. No graph, no problem! Luckily anyone can enhance PMM. So here’s how I made the …

In this blog post, I want to share a case we worked on a few days ago. I’ll show you how we approached the resolution of a MySQL performance issue and used Percona Monitoring and Management PMM to support troubleshooting. The customer had noticed a linear high CPU usage in one of their MySQL instances and was not able to figure out why as there was no much traffic hitting the app. We needed to reduce the high CPU usage on MySQL. The server is a small instance:

Models | 6xIntel(R) Xeon(R) CPU E5-2430 0 @ 2.20GHz
10GB RAM

This symptom can be caused by various different reasons. Let’s see how PMM can be used to troubleshoot the issue.

CPU

It’s important to understand where the CPU time is being consumed: user space, system space, iowait, and so on. Here we can see that CPU usage was …
