I'm on a role with questions. I'm curious to see if I can relieve processing pressure by adding a new vm.
Would you know how I would go about it? Also I would like to pull data from sources instead of have the sources push data to my site. Have you come across this scenario?

As a result my node1 is the only broker currently. Would this cause a bottleneck? If so is there a method to install and configures the 2 additional brokers post initial install? kindest regards Frank Sent from my Bell Samsung device over Canada's largest network. -------- Original message -------- From: Frank Horsfall <frankhorsf...@cunet.carleton.ca> Date: 2017-09-06 10:38 PM (GMT-05:00) To: user@metron.apache.org Subject: Re: Clearing of data to start over Thanks Laurens and Nick. I want to let the queues run over night to give us some possible insights into heap sizes etc. I currently have 3 vms configured each with 8 cores 500 gigs of data capacity and 30 gigs of memory. Elasticsearch has been configured with 10 gigs xmx. I've set storm worker childopts at 7 gigs for now so it takes a while to max out and generate heap errors. I deleted approx 6 million events and shut off the data generating apps. The idea is to see how much will be processed overnight. One thing that has me puzzled is why my bro app isn't emitting events. I double checked my config based on what's recommended but nothing is coming through. A mystery. lol Also I kept some notes during the whole process and want to share them if you are interested. let me know Frank Sent from my Bell Samsung device over Canada's largest network. -------- Original message -------- From: Laurens Vets <laur...@daemon.be> Date: 2017-09-06 6:17 PM (GMT-05:00) To: user@metron.apache.org Cc: Frank Horsfall <frankhorsf...@cunet.carleton.ca> Subject: Re: Clearing of data to start over Hi Frank, If you all your queues (Kafka/Storm) are empty, the following should work: - Deleting your elasticsearch indices: curl -X DELETE 'http://localhost:9200/snort_index_*', curl -X DELETE 'http://localhost:9200/yaf_index_*', etc... - Deleting your Hadoop data: Become the hdfs user: sudo su - hdfs Show what's been indexed in Hadoop: hdfs dfs -ls /apps/metron/indexing/indexed/ Output should show the following probably: /apps/metron/indexing/indexed/error /apps/metron/indexing/indexed/snort /apps/metron/indexing/indexed/yaf ... You can remove these with: hdfs dfs -rmr -skipTrash /apps/metron/indexing/indexed/error/ hdfs dfs -rmr -skipTrash /apps/metron/indexing/indexed/snort/ Or the individial files with hdfs dfs -rmr -skipTrash /apps/metron/indexing/indexed/error/FILENAME On 2017-09-06 13:59, Frank Horsfall wrote: Hello all, I have installed a 3 node system using the bare metal Centos 7 guideline. https://cwiki.apache.org/confluence/display/METRON/Metron+0.4.0+with+HDP+2.5+bare-metal+install+on+Centos+7+with+MariaDB+for+Metron+REST It has taken me a while to have all components working properly and I left the yaf,bro,snort apps running so quite a lot of data has been generated. Currently, I have almost 18 million events identified in Kibana. 16+ million are yaf based, and 2+ million are snort …. 190 events are my new squid telemetry, :). It looks like it still has a while to go before it catches up to current day. I recently shutdown the apps. My questions are: 1. Is there a way to wipe all my data and indices clean so that I may now begin with a fresh dataset? 2. Is there a way to configure yaf so that its data is meaningful ? It is currently creating what looks to be test data? 3. I have commented out the test snort rule but it is still generating the odd record which looks once again looks like test data. Can this be stopped as well? Kindest regards, Frank
