Subject [jira] Commented: (CHUKWA-384) REST API for HICC
Date Mon, 24 Aug 2009 06:38:59 GMT


Eric Yang commented on CHUKWA-384:

The charting widget could be modified with the following changes in mind:

"title":"Metrics From Rest API",
"categories":"System Metrics,Cluster,Status",
"description":"Display cluster related stats by percentage",
{"name":"legend","type":"radio","value":"on","label":"Show Legends","options":[{"label":"On","value":"on"},{"label":"Off","value":"off"}]}

By using the *series*,*data* key value pair, it will fetch data from the remote REST API data
source.  The remote data source should return:


Multiple data could be submitted, and the system will send ajax request to fetch each series.
 Let me know if this works for you.

> Currently, the HICC graphing JSP is capable of reading any JDBC-compatible database and
graphing the results, but it isn't able to parse JSON or other data from REST data sources.
 It would be good to define a REST data format and add the ability for the HICC graph JSP
to request and understand this format.
