Percona Monitoring and Management (PMM) 1.16.0 Is Now Available

PMM (Percona Monitoring and Management) is a free and open-source platform for managing and monitoring MySQL, MongoDB, and PostgreSQL performance. You can run PMM in your own environment for maximum security and reliability. It provides thorough time-based analysis for MySQL® and MongoDB® servers to ensure that your data works as efficiently as possible.

While much of the team is working on longer-term projects, we were able to provide the following feature:

  • MySQL and PostgreSQL support for all cloud DBaaS providers – Use PMM Server to gather Metrics and Queries from remote instances!
  • Query Analytics + Metric Series – See Database activity alongside queries
  • Collect local metrics using node_exporter + textfile …

Is It a Read Intensive or a Write Intensive Workload?

One of the common ways to classify database workloads is whether it is  “read intensive” or “write intensive”. In other words, whether the workload is dominated by reads or writes.

Why should you care? Because recognizing if the workload is read intensive or write intensive will impact your hardware choices, database configuration as well as what techniques you can apply for performance optimization and scalability.

This question looks trivial on the surface, but as you go deeper—complexity emerges. There are different “levels” of reads and writes for you to consider. You can also choose to look at event counts or at the time it takes to do operations. These can provide very different responses, especially as the cost difference between a single read and a single write can be an order of magnitude.

Let’s examine the TPC-C Benchmark from this point of view, or more specifically its …

Resource Usage Improvements in Percona Monitoring and Management 1.13

In Percona Monitoring and Management (PMM) 1.13 we have adopted Prometheus 2, and with this comes a dramatic improvement in resource usage, along with performance improvements!

What does it mean for you? This means you can have a significantly larger number of servers and database instances monitored by the same PMM installation. Or you can reduce the instance size you use to monitor your environment and save some money.

Let’s look at some stats!

CPU Usage

We can see an approximate 5x and 8x reduction of CPU usage on these two PMM Servers. Depending on the workload, we see CPU usage reductions to range between 3x and 10x.

Disk Writes

There is also less disk write bandwidth required:

On this instance, the bandwidth reduction is “just” 1.5x times. …
