Description Filip Kovář 2011-05-03 13:11:03 UTC
SELinux is preventing /usr/bin/perl from 'write' accesses on the directory /var/lib/munin/plugin-state.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that perl should be allowed write access on the plugin-state directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep munin_stats /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2011-05-03 14:06:47 UTC
Could you try to execute

# chcon -t system_munin_plugin_exec_t /usr/share/munin/plugins/munin_*

and re-test it. Thank you.
