Three Methods of Installing Percona Monitoring and Management

In this blog post, we’ll look at three different methods for installing Percona Monitoring and Management (PMM).

Percona offers multiple methods of installing Percona Monitoring and Management, depending on your environment and scale. I’ll also share comments on which installation methods we’ve decided to forego for now. Let’s begin by reviewing the three supported methods:

  1. Virtual Appliance
  2. Amazon Machine Image
  3. Docker

Virtual Appliance

We ship an OVF/OVA method to make installation as simple as …

All about Linkbench

Linkbench is a benchmark for social graph transaction processing. It lead to a paper, a post, benchmark client in Java and many blog posts from me. As a bonus, I also got to know the person who did the work for it - thanks Tim. The benchmark client has moved to my Github account because the upstream project has been archived (no comment). The repo is not active but someone recently added support for Postgres, someone else added …

Blog Poll: What Operating System Do You Run Your Production Database On?

In this post, we’ll use a blog poll to find out what operating system you use to run your production database servers.

As databases grow to meet more challenges and expanding application demands, they must try and get the maximum amount of performance out of available resources. How they work with an operating system can affect many variables, and help or hinder performance. The operating system you use for your database can impact consumable choices (such as hardware and memory). The operation system you use can also impact your choice of database engine as well (or vice versa).

Please let us know what operating system you use to run your database. For this poll, we’re asking which operating system you use to actually run your production database server (not the base operating system).

If you’re running …

The Insert Benchmark

The insert benchmark was first published by Tokutek in C++. Since then I converted it to Python, they made my Python version faster, I added support for MongoDB and I have been using it to evaluate storage engine efficiency. I think it is about 10 years old and been useful at finding things we can make better in storage engines. I hope to convert it to a faster language but in Python the code is still faster than storage engines for IO-bound workloads.

I use a helper script to run a sequence of tests. For all tests there is either one table shared by all clients or a separate table per client. Some storage engines suffer more from concurrency within a table. For MySQL each table has a primary key index up to 3 secondary indexes. I configure the tests to use 3 secondary indexes. The inserts during the load are in PK order but random for the secondary indexes. InnoDB benefits from the change buffer. MyRocks and MongoRocks benefit from …

Small servers for database performance tests

I use Intel NUC servers at home to test open source databases. I like them because they are small, quiet and don't use much power. For about 2 years I have been using NUC5i3ryh servers with a 5th gen core i3 CPU, 8gb of RAM, 2.5" SATA disk for the OS and 120gb Samsung 850 EVO m.2 for the database. I used this so much that I replaced the SSD devices last year after one reached the endurance limit.

I am upgrading to a new setup using NUC7i5bnh. This has a 7th gen core i5, 16gb of RAM, 2.5" SATA SSD (Samsung 850 EVO) for the OS and m.2 SSD ( …

How much disk space should I allocate for Percona Monitoring and Management?

I heard a frequent question at last week’s Percona Live conference regarding Percona Monitoring and Management (PMM): How much disk space should I allocate for PMM Server?

First, let’s review the three components of Percona Monitoring and Management that consume non-negligible disk space:

  1. Prometheus data source for the time series metrics
  2. Query Analytics (QAN) which uses Percona Server XtraDB (Percona’s enhanced version of the InnoDB storage engine)
  3. Orchestrator, also backed by Percona Server XtraDB

Of these, you’ll find that Prometheus is generally your largest consumer of disk space. Prometheus hits a steady state of disk utilization once you reach the defined storage.local.retention period. If you deploy Percona Monitoring and Management …
