That's all I have to share right now: youtu.be/O0wuD1RxjNY
Had you ever tried to make some sense out of the full backtrace for 1000+ threads in the mysqld process? Try this lame approach first: mysqlentomologist.blogspot.com/2022/02/how-to…
Slides from my #FOSDEM #MySQL devroom talk on different kinds of flame graphs: slideshare.net/ValeriyKravchu…
Slides from my recently completed talk on some less trivial usage of #bpftrace: slideshare.net/ValeriyKravchu…
My first #FOSDEM 2022 talk on #MariaDB, @macOS and #dtrace is over. Slides are also here: slideshare.net/ValeriyKravchu…
#bpftrace, #perf and #gdb work well together to solve more complex dynamic tracing problems: mysqlentomologist.blogspot.com/2022/02/how-to… more about this during my #FOSDEM 2022 MariaDB Devroom session tomorrow!
#dtrace, #MariaDB and #macOS - one of the winning combinations for #FOSDEM 2022: mysqlentomologist.blogspot.com/2022/01/dtrace…
Big numbers bring fun. @MySQL #bugoftheday, bugs.mysql.com/bug.php?id=106…, demonstrates yet another example of this fun.
Pushing #bpftrace to the limits, adding probes into every other line of the #MariaDB server code, accessing local variables and members of deeply nested structures passed as arguments... See you at #DOSDEM: fosdem.org/2022/schedule/…

The second day of @fosdem 2022 @MySQL Devroom will start with @MySQLbugs talking about flame graphs 🔥📊 for #MySQL DBAs 🐬 fosdem.org/2022/schedule/… #MySQLdevroom #fosdem2022
I've built all major versions of #MariaDB server on macOS from GitHub sources. Some details and reasons to do this are presented here: mysqlentomologist.blogspot.com/2022/01/first-… More at #FOSDEM 2022 :)
I am going to speak about #FlameGraphs again, this time at #FOSDEM 2022. See you in #MySQL and Friends Devroom: fosdem.org/2022/schedule/…
How to define structures for #bpftrace to be able to access deeply nested fields in the arguments of the functions traced (typical for #MariaDB and #MySQL): mysqlentomologist.blogspot.com/2022/01/access…
Easy way to compare two snapshots of waits reported by #MySQL's performance_schema: mysqlentomologist.blogspot.com/2022/01/differ…
More on #flamgraphs, this time to represent the output of #MySQL's EXPLAIN ANALYZE: mysqlentomologist.blogspot.com/2022/01/visual…
My first blog post about #MySQL and flame graphs this year: mysqlentomologist.blogspot.com/2022/01/visual…
