OpenTSDB Storage Metric
The service component data are stored in OpenTSDB in the metric format of ‘urlResp.metric name’, wherein for metrics whose names are prefixed with RC*, the metric format shall be urlResp.RC. Retrieve tags to add ptag. The value shall be the name of specific metric (such as RC400).
Value of instid in tags shall be urlpath. pgid represents AppBase path---AppHome path, e.g. intsid:http://10.10.37.44:8080/myapp/rs/query and pgid:/app/tomcat7---/app/tomcat7
Tips: Values of all tags are required to be escaped into the valid characters of opensdb. For instance, ':’ should be escaped into ' \u003a '
