>             Project: Karaf
>          Issue Type: Improvement
>          Components: decanter
>            Reporter: Jean-Baptiste Onofré
>            Assignee: Jean-Baptiste Onofré
>            Priority: Major
>             Fix For: decanter-2.3.0
> We did good improvement on Decanter alerting in 2.0.0 release.
> I would like to include the following improvement for 2.1.0:
> - be able to store some events (defined in the matcher) with the timestamp in order to
do alerting based on time. For instance: I saw this pattern three times in the last hour,
or this attribute is in this range in the last 10mn.
> - improve the checker syntax. Instead of a single line, I'm proposing to use JSON to
describe the alert pattern. It will allow us to have multi-attribute matcher and different
filter. For instance:
> {code}
> { "attributes" : ["ObjectName:*foo*", "QueueSize:*"],
> "alert": { "type":"greater","value":"0"},
> "time":"now"}
> {code}
