I also have this problem and i backtracked it to the patch file
mariadb-show-status.patch
which backports the munin github commit: e5f12ef57c75d37aa2e3444cc448598f3c32b0ea
but what seems missing the follow-up commit:

Description of problem: When $section_map{$sec}->() does not exists, munin mysql_ plugin fails with errors: Use of uninitialized value in subroutine entry at /etc/munin/plugins/mysql_qcache_mem line 1105. Can't use string ("") as a subroutine ref while "strict refs" in use at /etc/munin/plugins/mysql_qcache_mem line 1105. Fix is to remove line 1105 with: $section_map{$sec}->(); As the case before that line does what's expected - use the value only if it exists. Version-Release number of selected component (if applicable): munin-node-2.0.30-5.el7.noarch.rpm How reproducible: always Steps to Reproduce: 1. Install munin-node and mysql 2. Configure some mysql_ plugin e.g. ln -sf /usr/share/munin/plugins/mysql_ /etc/munin/plugins/mysql_qcache_mem 3. munin-run mysql_qcache_mem Actual results: # munin-run mysql_qcache_mem Use of uninitialized value in subroutine entry at /etc/munin/plugins/mysql_qcache_mem line 1105. Use of uninitialized value in subroutine entry at /etc/munin/plugins/mysql_qcache_mem line 1105. Can't use string ("") as a subroutine ref while "strict refs" in use at /etc/munin/plugins/mysql_qcache_mem line 1105. Expected results: # munin-run mysql_qcache_mem query_cache_size.value 4194304 Qcache_free_memory.value 941184
