nxapi/nxtools.py support ES 6.x

[volp1s]

At this moment nxapi/nxtools.py supports only Elasticsearch 1 / 2 / 5 Why this limitation? Is this compatibility planned to be extended? I'm trying to get this working with ES 6.1 Thx

Hello, We don't use ES6 yet. If you happen to make it work, we'll gladly review and merge MR ;)

Hi, Just need to replace all "2", "5" by "2", "5", "6" in the nxtransform.py file ES 5 and 6 seems to have a good backward compatibility It has worked fine for me, no troubles by now

Watch out for using paths you might expect the shell to expand. I was getting a Unable to create the index/collection : nxapi events, Error: create() takes at least 5 arguments (5 given) and it looked like the error log file had been ignored:

./nxtool.py -c nxapi.json --files=~/nginx/log/error.log
# size :1000
Unable to create the index/collection : nxapi events, Error: create() takes at least 5 arguments (5 given)
WARNING:root:List of files :[]

The ~ didn't get expanded by python. But using:

./nxtool.py -c nxapi.json --files=/Users/jay/nginx/log/error.log

caused all the log entries to get added to the nxapi elasticsearch index.
