Library is being modified to watch a folder for FTP uploaded CSV files.

  • importCSVfolder - import csv file in a folder and watch for additions
  • hashDir - returns a list of change files between runs
  • csvToInfluxdb - import csv to influxdb
  • preProcess - custom user functionality

importCSVfolder Usage

  • Usable in cron like usage, or just once off runs
  • Able to set folder to monitor for changes
usage: importCSVfolder.py -i '/tmp/upload' --watch True --config '.csv.json' 
                                            --hashstore '.hashstore' -p True

  required
  -i [INPUT], --input [INPUT]
                        Path to folder to check                        
  optional
  -w [WATCH] --watch [WATCH]

                        Default = False                  
  -c [CONFIG] --config [CONFIG]
                        Store name for dirtory hashes
                        Default = csv.json

  -s [HASHSTORE] --hashstore [HASHSTORE]  
                        help='hashed file store'
                        default= .hashstore

  -p [PREPROCESS] --preprocess [PREPROCESS] default=False,
                        Enable use of preprocessing.py script
                        Very application specific at the moment
                        Default = False

requires $pip install minotaur

hashDir Usage

usage: hashDir.py -i [INPUT] -s [STORE]
  required
  -i [INPUT], --input [INPUT]
                        Path to folder to check
  optional                      
  -s [STORE], --store [STORE]
                        Store name for dirtory hashes
                        Default = .oldhash

returns [HASH, FULL PATH OF FILE, FILE NAME]

csvToInfluxdb Usage

Require $pip install influxdb

usage: csvToInfluxdb.py -i [INPUT] -c [CONFIG]
  required
  -i [INPUT], --input [INPUT]
                        Path to csv file 
  optional
  -c [CONFIG], --config [CONFIG]

                        Default = csv.json

The following command will insert the file into a influxdb database:

python csvToInfluxdb.py -i logs.csv -c csv.json

PreProcess

user code to manipulate files lists and jsons file. Allows automating some extra tasks

  • Find deviceID from file name
  • Update measurement name to DevID
  • Remove files from file list, if set phrase is found
