Redhat EL 5.1, Java 6
Description
In Chukwa Database aggregator, we could execute SQL statement which looks like:
insert into [cluster_system_metrics] (select [avg(system_metrics)] from [system_metrics] where timestamp between [past_10_minutes] and [now]);
This new feature is to bring macro language to HICC charting. The user can write statement like:
select timestamp,host,load_5 from [system_metrics] where timestamp between [start] and [end];
This statement will automatically expand to:
select timestamp, host, load_5 from system_metrics_2045_week where timestamp between '2009-03-02 00:00:00' and '2009-03-03 00:00:00';
