Bertrand Delacretaz commented on SLING-2983:
--------------------------------------------
Added a JMX binding in revision 1508067, allows for writing rules that evaluate
combinations of JMX attributes, such as:
{
"sling:resourceType" : "sling/healthcheck/rules",
"namespace": "script",
"ruleName": "Example javascript expression that combines two JMX attributes",
"qualifier": "ecma",
"expression": 'jmx.attribute("java.lang:type=ClassLoading",
"LoadedClassCount") > 100 &&
jmx.attribute("osgi.core:type=framework,version=1.5","FrameworkStartLevel") >
1',
"tags" : ["script","javascript", "jmx" ],
"jcr:primaryType": "nt:unstructured"
}
> Scripted expressions for Health Check rules

> URL: https://issues.apache.org/jira/browse/SLING-2983
> Project: Sling
> Issue Type: Bug
> Components: Extensions
> Reporter: Bertrand Delacretaz
> Assignee: Bertrand Delacretaz
> Priority: Minor
>
> I have implemented scripted expressions for Health Check rules, that can use
> any Sling scripting language and must return true for the Rule to be
> successful.
> Here's two examples from [1]:
> scripted-ecma.json:
> {
> "sling:resourceType" : "sling/healthcheck/rules",
> "namespace": "script",
> "ruleName": "Test javascript (ecma) rule",
> "qualifier": "ecma",
> "expression": "Math.round(2.6) == 3",
> "tags" : ["script","javascript"],
> "jcr:primaryType": "nt:unstructured"
> }
> scripted-groovy.json:
> {
> "sling:resourceType" : "sling/healthcheck/rules",
> "namespace": "script",
> "ruleName": "Test Groovy rule",
> "qualifier": "groovy",
> "expression": "someList = [1776, -1, 33, 99, 0, 928734928763] ; someList[2]
> == 33",
> "tags" : ["script","groovy"],
> "jcr:primaryType": "nt:unstructured"
> }
> [1]
