Usage

This section describes some examples on how to use jsonpath to access data exported by EBOA.

• Import parser

from jsonpath_ng.ext import parse as jsonpath

• Access to root node:

jsonpath("$").find(data)

• Access to events node:

jsonpath("$.events").find(data)

• Access to events nodes which have a value with name "status" and value "MISSING":

jsonpath("$.events[?values[?name=='status' & value=='MISSING']] ").find(data)

• Get the duration in seconds of a timeline of events, filtered using jsonpath:

jsonpath("$.events[?values[?name=='status' & value=='MISSING']] ").find(dhus_product_completeness_l1_slc_events)|map(attribute="value")|get_timeline_duration_from_events_json
