Description of problem: When there are missing some InnoDB statistics data (or parsing was not completely successful) Munin plugins `/etc/munin/plugins/mysql_innodb_io_pend` and `/etc/munin/plugins/mysql_innodb_insert_buf` report error "Use of uninitialized value in printf at ... line 885." which causes that all InnoDB related graphs are with zero values. When lines 885-886 of file "/usr/share/munin/plugins/mysql_" (from munin-node package) are updated to: printf "%s.value %s\n", clean_fieldname($ds->{name}), defined $data->{$ds->{name}} ? $data->{$ds->{name}} : 'U'; it works without error and graphs are there. Original lines 885-886 are: printf "%s.value %s\n", clean_fieldname($ds->{name}), $data->{$ds->{name}}; Proposed change is taken from the latest plugin sources: https://github.com/munin-monitoring/munin/blob/3fff4fd45972dbfbfee3c7b0d5af653cb4aa3cfb/plugins/node.d/mysql_#L1811,L1813 Version-Release number of selected component (if applicable): munin-node-2.0.33-1.el7.noarch.rpm How reproducible: Steps to Reproduce: 1. Install and configure munin 2. Enable some munin mysql innodb plugin e.g.: ln -sf /usr/share/munin/plugins/mysql_ /etc/munin/plugins/mysql_innodb_io_pend systemctl restart munin-node 2. Create some InnoDB table 3. Run: munin-run mysql_innodb_io_pend
