feature

Prototype:feature

Description: Finds feature_set_X and feature_unset_X classes and sets/unsets X persistently

Finds all classes namedfeature_unset_X and clear class X.

Finds all classes namedfeature_set_DURATION_X and sets class Xpersistently for DURATION. DURATION can be any digits followed byk,m, org.

In inform mode (-I) it will report what it does.

Example:Set classxyz for 10 minutes, classqpr for 100 minutes, andijk for 90m minutes. Unset classabc.cf-agent -I -f ./feature.cf -b feature -Dfeature_set_10_xyz,feature_set_100_qpr,feature_set_90m_ijk,feature_unset_abc

Implementation:

code

feature_test

Prototype:feature_test

Description: Finds feature_set_X and feature_unset_X classes and reports X

Note that this bundle is intended to be used exactly likefeatureand just show what's defined or undefined.

Example:Check classesxyz,qpr,ijk, andabc.cf-agent -I -f ./feature.cf -b feature_test -Dfeature_set_10_xyz,feature_set_100_qpr,feature_set_90m_ijk,feature_unset_abc

Implementation:

code

bundleagentfeature_test{classes:"parsed_$(on)"expression=>regextract("feature_set_([0-9]+[kmgKMG]?)_(.*)",$(on),"extract_$(on)");"parsed_$(off)"expression=>regextract("feature_unset_(.*)",$(off),"extract_$(off)");vars:"on"slist=>classesmatching("feature_set_.*");"off"slist=>classesmatching("feature_unset_.*");reports:"$(this.bundle): have$(extract_$(on)[2])"if=>"$(extract_$(on)[2])";"$(this.bundle): have no$(extract_$(on)[2])"if=>"!$(extract_$(on)[2])";"$(this.bundle): have$(extract_$(off)[1])"if=>"$(extract_$(off)[1])";"$(this.bundle): have no$(extract_$(off)[1])"if=>"!$(extract_$(off)[1])";}
