Percona’s Open Source Data Management Software Survey

PerconaSurvey

Click Here to Complete our New Survey!

Last year we informally surveyed the open source community and our conference attendees.
The results revealed that:

  • 48% of those in the cloud choose to self-manage their databases, but 52% were comfortable relying on the DBaaS offering of their cloud vendor.
  • 49% of people said “performance issues” when asked, “what keeps you up at night?”
  • The major decision influence for buying services was price, with 42% of respondents keen to make the most of their money.

We found this information so interesting that we wanted to find out more! As a result, we are pleased to announce the launch of our first annual Open Source Data Management Software Survey.

The final results will be 100% anonymous, and will be made freely available on Creative Commons.

How Will This Survey Help The Community?

Unlimited access to accurate market data is important. Millions of open source projects are in play, and most are dependent on databases. Accurate market data helps you track the popularity of different databases, as well as seeing how and where these databases are run. This helps us all build better software and take advantage of shifting trends.

Thousands of vendors are focused on helping SysAdmins, DBAs, and Developers get the most out of their database infrastructure. Insightful market data enables them to create better tools that meet current demands and grow the open source database market.

We want to assist companies who are still deciding what, how, and where to run their systems. This information will help them understand the industry direction and allow them to make an informed decision on the software and services they choose.

How Can You Help Make This Survey A Success?

Firstly, please share your insight into current trends and new developments in open source data management software.

Secondly, please share this survey with other people who work in the industry, and encourage them to contribute.

The more responses we receive, the more useful this will be to the whole open source community. If we missed anything, or you would like to ask other questions in future, let us know!

So tell us; who are the big fish, and which minnows are nibbling at their tails?! Is the cloud giving you altitude sickness, or are you flying high? What is the next big thing and is everyone on board, or is your company lagging behind?

Preliminary results will be presented at our annual Percona Live Conference in Austin, Texas (May 28-30, 2019) by our CEO, Peter Zaitsev and released to the open source community when finalized.

Percona Monitoring and Management (PMM) 1.17.1 Is Now Available

Percona Monitoring and Management 1.17.0

Percona Monitoring and Management

Percona Monitoring and Management (PMM) 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®, MongoDB®, and PostgreSQL® servers to ensure that your data works as efficiently as possible.

In this release, we are introducing support for detection of our upcoming PMM 2.0 release in order to avoid potential version conflicts in the future, as PMM 1.x will not be compatible with PMM 2.x.

Another improvement in this release is we have updated the Tooltips for Dashboard MySQL Query Response Time by providing a description of what the graphs display, along with links to related documentation resources. An example of Tooltips in action:

PMM 1.17.1 release provides fixes for CVE-2018-16492 and CVE-2018-16487 vulnerabilities, related to Node.js modules. The authentication system used in PMM is not susceptible to the attacks described in these CVE reports. PMM does not use client-side data objects to control user-access.

In release 1.17.1 we have included two improvements and fixed nine bugs.

Improvements

  • PMM-1339: Improve tooltips for MySQL Query Response Time dashboard
  • PMM-3477: Add Ubuntu 18.10 support

Fixed Bugs

  • PMM-3471: Fix global status metric names in mysqld_exporter for MySQL 8.0 compatibility
  • PMM-3400: Duplicate column in the Query Analytics dashboard Explain section

A New PMM Dashboard to Monitor Memory Usage!

Dashboard to Monitor Memory Usage in Linux

While the PMM team works hard on our PMM 2.0 release, we have been working on a few things in the background which we’d like to show off !  In particular we have developed a new dashboard that displays metrics related to memory usage on Linux systems. The dashboard leverages information collected by node_exporter. The graphs take advantage of  /proc filesystem files, specifically:

  • meminfo: Provides information about distribution and utilization of memory. This varies by architecture and compile options.
  • vmstat: Provides information about block IO and CPU activity in addition to memory.

The information is split into five sections:

  1. Total Memory
  2. VMM (Virtual Memory Manager) Statistics
  3. Memory Statistics
  4. Number and Dynamic of Pages
  5. Pages per Zone

The dashboard will be included as part of the PMM 2.0 release. For you early adopters, you can get it from GrafanaLab and install it alongside your existing Dashboards – it won’t overwrite anything!

Please notice that the dashboard can be imported by ID (9692) in Grafana versions since 5.4.2 or should be downloaded and imported manually in older Grafana versions.
