Subject [jira] Commented: (CHUKWA-520) Metrics graphing REST api for HBase
Date Sun, 12 Sep 2010 19:22:32 GMT


Eric Yang commented on CHUKWA-520:

Sure,  most of the document will go into javadoc, but I also would like to start developer
document for hicc.  I think I will start HICC document in wiki then move to xml document when
API is ready for public.

> HICC chart.jsp has the ability to graph metrics from web service API.  The usage pattern
looks like this:
> {noformat}
> /hicc/jsp/chart.jsp?data=[url to json data]
> {noformat}
> The expected data format for the data url looks like this:
> {noformat}
> { "name": "series name", "data": [[x,y],[x2,y2],...[x1000,y1000]]}
> {noformat}
> Metrics graphing REST api should load data from HBase and convert to the above JSON output
format for graphing.
> The suggested REST API looks like this:
> {noformat}
> /hicc/v1/metrics/[table_name]/[column_family]:[column]/[row_key]?start=[yyyyMMddHHmmss]&end=[yyyyMMddHHmmss]
> {noformat}
> row_key can be supplied like a macro, i.e. [host].  This will pick up selected host from
HICC session variable.
