So, first off, it's not a basic question at all and thanks for asking it. I'm sure if it's not clear to you, then it's not clear to many and bears some reinforcement and clarification.
- Metron does indeed enable the deployment and use of machine learning models on data ingested into Metron - Metron runs atop Hadoop (storm + kafka + hdfs + hbase), so you likely wouldn't run this successfully on a VM, but rather a cluster. We do support running Metron for demonstration purposes and development purposes inside a VM, but that's not a production configuration, I'd like to make clear. Models deployed via MaaS can be interacted with via Stellar on data ingested into Metron under a couple caveats. There are two ways to ingest data into Metron: - Via a packet capture sensor (fastcapa) to Kafka to the pcap storm topology, which writes directly to HDFS with no preamble or enrichment - Via another, lower velocity sensor (e.g. bro for deep packet inspection or yaf for flow data) which is routed to a parser topology, then to enrichment and finally to indexing We do not, at present, support interacting with models (or, indeed, any enrichment) on raw packet data (the first case above). We do, however, support it on the second usecase. The example at https://github.com/apache/ metron/tree/master/metron-analytics/metron-maas-service#example demonstrates ingesting web proxy data and using a dummy machine learning model to pick out domains which are synthetic and likely to represent communication to a botnet (the DGA model in that example is crude and could easily be replaced with the example I posed earlier, btw). Anyway, so for you to use your own ML model, you'd do the following: 1. Ingest the sensor data source that you want to ingest into a kafka topic 2. Create or reuse one of the existing parsers that we support to convert the data from your data source 3. Create your model (see https://gist.github.com/cestella/ 8dd83031b8898a732b6a5a60fce1b616 <https://gist.github.com/cestella/8dd83031b8898a732b6a5a60fce1b616> as an example) 4. refer to your model from stellar 1. In the example I mentioned, we're doing that at https://github.com/apache/metron/tree/master/metron-analytics/metron-maas-service#adjust-configurations-for-squid-to-call-model 2. You might consider doing it in the enrichment topology, but to get you started, doing it as a field trasnformation as in the example should suffice Hopefully that'll clear some things up. I'm about to give a talk about this next week at Dataworks summit, so I'll be sure to follow-up here with the deck. There's also a blog post that will eventually be going out with this walked through more directly. If I missed osmething or if something isn't clear yet, I'll be sure to keep at it. :) Best, Casey On Mon, Jun 5, 2017 at 1:21 PM, <sml...@libero.it> wrote: > Hello Casey, > > your answer makes something more clear, but not at all. > > My question about ML models was because somewhere on the web I read that > Metron comes with ML. > But maybe it's better to say that it supports ML models. > > If I understood well, I can run Metron in a virtual machine connected to > my network.
