filecollector 0.2.0

Simple file collector - compress/serve/send/anonymizie files

filecollector

Service for collecting and processing files (with hooks)

Features

• collect files and compress them (on command)
• anonymization
• run custom scripts on output file / processed files
• start/stop simple fileserver (at collect output location)
• stream collected files to fluentd (line by line)

Requirements

• python 3.5+
• pip

Installation

pip install filecollector

Usage

It has 2 main components right now: collector and server. Collector is responsible to collect/anonymize the files and run hook scripts on those. Server is only a browser for the collected files.

At the start you need to create a yaml configuration file for the collector. Only this configuration is required as an input for filecollector.

Start the collector

filecollector collector start --config filecollector.yaml -p /my/pid/dir

Start the server

filecollector server start --config filecollector.yaml -p /my/pid/dir

Configration

Simple configuration example

server:
    port: 1999
    folder: "../example/files" 
collector:
    files:
    - path: "example/example*.txt"
      label: "example"
    rules:
    - pattern:  \d{4}[^\w]\d{4}[^\w]\d{4}[^\w]\d{4}
      replacement: "[REDACTED]"
    processFileScript: example/scripts/process_file.sh
    compress: true
    useFullPath: true
    outputScript: example/scripts/output_file.sh
    processFilesFolderScript: example/scripts/tmp_folder.sh
    deleteProcessedTemplateFiles: true
    outputLocation: "example/files"

Running simple example:

# start collector 
filecollector collector start --config example/filecollector.yaml -p /my/pid/dir
# start server for browsing
filecollector server start --config example/filecollector.yaml -p /my/pid/dir

Running with docker:

# collector only
docker run --rm -v /my/path/to/config:/my/path/to/config oleewere/filecollector:latest --config /my/path/to/config/filecollector.yaml

Fluentd configuration example

collector:
    files:
    - path: "example/example*.txt"
      label: "txt"
    rules:
    - pattern:  \d{4}[^\w]\d{4}[^\w]\d{4}[^\w]\d{4}
      replacement: "[REDACTED]"
    compress: false
    useFullPath: true
    deleteProcessedTempFilesOneByOne: true
    outputLocation: "example/files"
    fluentProcessor:
      host: "localhost"
      port: 24224
      tag: example

Fluentd configuration:

<source>
  @type forward
  port 24224
  bind 0.0.0.0
</source>

<match example.**>
   @type stdout
</match>

Running fluentd example:

# start fluentd 
fluentd --config example/fluentd.conf
# start collector 
filecollector collector start --config example/fluentd-filecollector.yaml -p /my/pid/dir

Configuration options

server

The server block, it contains configurations related with the filecollector server component.

server.port

Port that will be used by the filecollector server.

server.folder

The folder that is server by the file server.

collector

The collector block, it contains configurations related with the filecollector collector component.

collector.files

List of files (with path and label fields are required) that needs to be collected.

collector.files.path

Filename or wildcard that represents the files that is needed to be collected.

collector.files.label

It will be used as a first level folder inside outputLocation for the file collection. E.g. if this value is mylabel, the output will go into <outputLocation>/mylabel

collector.files.folderPrefix

If it's set, the filecollector will put the files into this folder (inside outputLocation, but before label)

collector.files.useFullPath

Use full path for processed files (inside outputLocation). Can be useful if because of the wildcard patterns, the base file name are the same for different files from different folders. It overrides the collector.useFullPath option.

collector.files.excludes

The path options can be used as wildcards. There are other options like: useFullPath or excludes. The useFullPath option is the same as the below one, but it overrides the global behavior (default: false). The excludes option is a list of path patterns that should be excluded from path pattern matches.

collector.rules

List of anonymization rules that can be run against the file inputs. (pattern field for matching, replacement for the replacement on match)

collector.compress

At the end of the filecollection, the output folder is compressed. Default value is true.

collector.compressFormat

Compression format, possible values: zip, tar, gztar, bztar. Default value is zip.

collector.outputLocation

Output location (directory), where the processed file(s) will be stored.

collector.useFullPath

Use full path for processed files (inside outputLocation). Can be useful if because of the wildcard patterns, the base file name are the same for different files from different folders. Default value is true.

collector.checkDiskSpace

IF this option is set, before file processing - based on the file size and requiredDiskSpaceRatio option - it will check you have enough space for copying those files into your working directory or not. Default value is true.

collector.requiredDiskSpaceRatio

This value is used for checkDiskSpace option. The required disk space will be calculated with this value (as a multiplier, e.g. if my files full size is 100MB and this setting is 1.6, the processing will require 160MB free space). Default value is 1.0.

collector.processFileScript

Script that runs agains 1 processed file. It gets the filename and the label for a processed file.

collector.processFilesFolderScript

Script that runs once after the files are collected. It gets the folder name (where the files are processed) as an input.

collector.preProcessScript

Script that runs before the files are collected. It gets the folder name (where the files are processed) as an input.

collector.outputScript

Script that runs once with the compressed output file name as an input.

'collector.deleteCompressedFile'

Delete compressed file at the end of the file collection. That can be useful e.g. if an output script upload the compressed file somewhere adn it is needed to do a cleanup. Default value is false.

collector.deleteProcessedTempFiles

After collection of the files + compression, the collected files are deleted. Can be useful to disable this behaviour compress option is disabled. Default value is true.

collector.deleteProcessedTempFilesOneByOne

If this option is set, files are deleted right after processed (one at a time). That can be useful if compression is disabled, and you would like to stream large files to fluentd. Default value is false.

collector.fluentProcessor

Fluentd related section for processing files line by line - streaming data by fluentd forward protocol.

collector.fluentProcessor.host

Fluentd host (for forward protocol). Default value: localhost.

collector.fluentProcessor.port

Fluentd port (for forward protocol). Default value: 24224.

collector.fluentProcessor.tag

Fluentd tag for streaming lines. The generated tag for forward protocol is <collector.fluentProcessor.tag>.<file label for monitored file>.

collector.fluentProcessor.messageField

The processed lines are mapped for this field before data has been sent to Fluentd. Default value: message.

collector.fluentProcessor.includeTime

If this is enabled, current time is included in the fluentd data event. (as time field). Default value: false.

collector.logger

Logger related configurations for the collector.

collector.logger.level

Logger level that is used during logging.

collector.logger.format

Format of the log events. Default value is %(message)s.

collector.logger.file

File where the log will write the logging events, if it is not set, only stdout will be used.
