Export Data

e.g.

URL index type

exportEsData("http://10.100.142.60:9200","watchdog","mexception").exportData()

export file name: watchdog_mexception.json

'''

#exportEsData("http://10.100.142.60:9200","watchdog","mexception").exportData()

exportEsData("http://10.100.142.60:9200","watchdog","mexception").exportData()

'''

Import Data

*import file name:watchdog_test.json (important)

"_" front part represents the elasticsearch index

"_" after part represents the elasticsearch type

e.g.

URL index type

mportEsData("http://10.100.142.60:9200","watchdog","test").importData()

'''

#importEsData("http://10.100.142.60:9200","watchdog","test").importData()

importEsData("http://10.100.142.60:9200","watchdog","test").importData()
