#pigsty-moloch-plugin
ver 0.0.1
This plugin tags moloch sessions with IDS alerts, so you can have queries like
tags == snort_classification_trojan-activity or tags == suricata__signatureID_2016758
Alerts are readed from unified2 log files. Snort, Suricata, Sagan can write unified2 logs.
It should work as simple as npm install and vi config.

Moloch is an open source, large scale IPv4 packet capturing (PCAP), indexing and database system. A simple web interface is provided for PCAP browsing, searching, and exporting. Moloch is not meant to replace IDS engines but instead work along side them to store and index all the network traffic in standard PCAP format, providing fast access.
see https://github.com/threatstack/pigsty
Pigsty is designed as a replacement for Barnyard2. It's written in Javascript using Node.js. Pigsty's output architecture is plugin based.
- install moloch or run it
- install suricata on moloch capture machine and set it to log into unified2 or run it
- install pigsty on same machine
- install pigsty-moloch-plugin
- edit pigsty config:
- set reference file locations
- set log dir location
- add output section 'moloch-plugin'
- run pigsty with DEBUG=pigsty-moloch-plugin
! depends on https://npmjs.org/package/hashtable , debug and pigsty-plugin

-
molochConfigFileLocation
plugin reads elasticsearch related options from moloch config
set it for example '/data/moloch/etc/config.ini'
-
dbModuleLocation
moloch viewer uses its own db module, what you can not (yet) install with npm
so you have to point on its location
set if for example '/data/moloch/viewer/db.js'
- iniparserModuleLocation
- asyncModuleLocation
- keepaliveagentModuleLocation
set those modules to point on moloch install
- iniparserModuleLocation : '/data/moloch/viewer/node_modules/iniparser/lib/node-iniparser.js',
- asyncModuleLocation : '/data/moloch/viewer/node_modules/async/lib/async.js',
- keepaliveagentModuleLocation : '/data/moloch/viewer/node_modules/keep-alive-agent/index.js',
if not set, plugin looks for them as installed with 'npm install ... -g'
-
eventQueueMaxSize int
how many events to keep in prededup queue
default is 128
-
minFreeMemory int bytes
-
maxHeapSize int bytes
if you set those and the limit is reached, plugin will emit error, tells the spooler that it is full and pauses (no seppuku), recovery possible but not guaranteed
have some log collecting/parsing/monitoring/whatever running
-
maxKeepAliveSockets int
how many sockets to keep open with elasticsearch
default is 20
-
printStatstoConsole true/false
-
printStatsInterval int seconds
prints stats to console, see usage
-
tagPrefix
your favorite prefix here, default is 'unified2'
iniparserModuleLocation : 'iniparser';
keepaliveagentModuleLocation : 'keep-alive-agent';
asyncModuleLocation : 'async';
eventQueueMaxSize : 128;
maxKeepAliveSockets : 20;
printStatsInterval : 60;
tagPrefix : 'unified2'
