Metrics graphing REST api for HBase
-----------------------------------
Key: CHUKWA-520
URL: https://issues.apache.org/jira/browse/CHUKWA-520
Project: Chukwa
Issue Type: New Feature
Components: User Interface
Environment: Java 6, Mac OS X 10.6
Reporter: Eric Yang
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.
