I was trying to set up the newer mysql_ plugin for Munin, but got the following error when using the “suggest” argument to determine how to link the file. The “fix” was to install the perl-Cache-Cache.noarch package via yum.

Missing dependency Cache::Cache at ./mysql_ line 728

As an FYI – you install different graphs from a single plugin by creating a symbolic link to the plugin with an appropriate name, for example:

ln -s mysql_ mysql_connections

The Error

Unable to suggest the plugin options.

[root@db1 plugins]# ./mysql_ suggest
Missing dependency Cache::Cache at ./mysql_ line 728.

The “Fix”

Install Perl’s Cache::Cache.

yum -y install perl-Cache-Cache.noarch

Success

You should now be able to suggest the plugin options.

[root@db1 plugins]# ./mysql_ suggest
