The Ingress NGINX Controller is one of the most popular choices for managing the inbound traffic to K8s. It acts as a reverse proxy and load […]]]> https://www.percona.com/blog/percona-monitoring-and-management-setup-on-kubernetes-with-nginx-ingress-for-external-databases/feed/ 0 95637 https://www.percona.com/blog/kubernetes-observability-code-profiling-with-flame-graphs/ https://www.percona.com/blog/kubernetes-observability-code-profiling-with-flame-graphs/#respond Thu, 12 Oct 2023 13:41:50 +0000 https://www.percona.com/blog/?p=91420 In this blog post, we’ll review how to run Linux profilers such as perf and produce flame graphs on Kubernetes environments.Flame graphs are a graphical representation of function calls. It shows which code paths are more busy on the CPU in given samples.

The usage of simple OS tools to find the culprit has been a widely used technique for a long time by PostgreSQL and Oracle DBAs, but it didn’t […]]]> https://www.percona.com/blog/a-simple-approach-to-troubleshooting-high-cpu-in-mysql/feed/ 2 67247 https://www.percona.com/blog/multi-threaded-slave-statistics/ https://www.percona.com/blog/multi-threaded-slave-statistics/#comments Wed, 19 Jul 2017 17:02:34 +0000 https://www.percona.com/blog/?p=44284 In this blog post, I’ll talk about multi-threaded slave statistics printed in MySQL error log file.MySQL version 5.6 and later allows you to execute replicated events using parallel threads. This feature is called Multi-Threaded Slave (MTS), and to enable it you need to modify the [crayon-664c78985227b242654413-i/] variable to a value greater than 1.Recently, a few customers […]]]> https://www.percona.com/blog/multi-threaded-slave-statistics/feed/ 3 44284 https://www.percona.com/blog/mysql-super_read_only-bugs/ https://www.percona.com/blog/mysql-super_read_only-bugs/#comments Wed, 08 Feb 2017 15:23:31 +0000 https://www.percona.com/blog/?p=40671 This blog we describe an issue with MySQL 5.7’s super_read_only feature when used alongside with GTID in chained slave instances.BackgroundIn MySQL 5.7.5 and onward introduced the gtid_executed table in the MySQL database to store every GTID. This allows slave instances to use the GTID feature regardless whether the binlog option is set or not. Here is an […]]]> https://www.percona.com/blog/mysql-super_read_only-bugs/feed/ 2 40671
