There’s just one week to go before the first of this year’s Percona University events in South America. We’re really pleased with the lineup for all three events. We’re also incredibly happy with the response that we have had from the community. While we realize that a free event is… well… free… you are […]Read more
We started hosting Percona University a few years back with the aim of sharing knowledge with the open source database community. The events are held in cities across the world. The next Percona University days will visiting Uruguay, Argentina, and Brazil, in a lightning tour at the end of April.
Montevideo, Tuesday, April 23 2019 […]Read more
This year at our Open Source Database Conference we’re celebrating open source database technologies that don’t fit into the MySQL®, MongoDB®, MariaDB®, or PostgreSQL realms by featuring them in their very own track. The glamorously-named Other Open Source Databases track! As unbiased champions of open source database solutions, we embrace all flavors of open […]Read more
If you have set up per-process metrics in Percona Monitoring and Management, you may have found yourself in need of tuning it further to not only group processes together, but to display some of them in isolation. In this blogpost we will explore how to modify the rules for grouping processes, so that you […]Read more
Recently we had a customer that had issues with a filled disk on the server hosting their Docker pmm-server environment. They were not able to access the web UI, or even stop the pmm-server container because they had filled the /var/ mount point.
Setting correct expectations
The best way to avoid these kinds of issues in […]
Do you need to modify the metrics collected from Linux by Percona Monitoring and Management (PMM)? In this blog post we will see how to enable, disable, and update collected metrics on PMM’s linux:metrics exporter.
We will assume that the PMM client packages are installed, and they are configured already.
Using a custom list of metrics
Let’s now suppose we […]
Some years ago, Peter Z wrote a blogpost about using MySQL Sandbox to deploy multiple server versions. Last February, Giuseppe introduced us to its successor: dbdeployer. In this blogpost we will demonstrate how to use it. There is a lot of information in Giuseppe’s post, so head there if you want a deeper dive.
First step […]
In this blog post, we’ll see how to use different mount points on PMM Docker deployments (Percona Monitoring and Management). This is useful if you want to use other mount points for the different directories, or even if you want to use a custom path that is not bound to Docker’s volumes directory (which is […]Read more
In this short blogpost, we’ll show you how to use the mysql_random_data_load tool to insert random data into tables. This is a great aide in testing when you have empty tables and need them to be populated with data. We’ve all done it manually (the INSERT INTO … VALUES … way), but that is surely […]Read more
In this post, we will discuss how to search code with the help of cscope. Let’s begin by checking its description and capabilities (quoting directly from http://cscope.sourceforge.net/):
Cscope is a developer’s tool for browsing source code.
Allows searching code for:
all references to a symbol
functions called by a function
functions calling a function
regular expression pattern
