Store, Analyze Ingest User Interface a full-text based, distributed NoSQL database. Written in Java, built on Apache Lucene Commonly used for log analytics, full-text search, security intelligence, business analytics, and operational intelligence use cases. Use REST API (GET, PUT, POST, and DELETE ) for storing and searching data Data is stored as documents (rows in relational database) Data is separated into fields (columns in relational database) Relational Database Elasticsearch Database Index Table Type Row/Record Document Column Name Field Terminology Cluster: A cluster consists of one or more nodes which share the same cluster name. Node: A node is a running instance of elasticsearch which belongs to a cluster. Terminology Index: Collection of documents Shard: An index is split into elements known as shards that are distributed across multiple nodes. There are two types of shard, Primary and replica. By default elasticsearch creates 1 primary shard and 1 replica shard for each index. Terminology Shard 1 Replica 1 Replica 2 Shard 2 Node 1 Node 2 cluster Terminology Documents { • Indices hold documents in "_index": "netflow-2020.10.08", "_type": "_doc", serialized JSON objects "_id": "ZwkiB3UBULotwSOX3Bdb", "_version": 1, • 1 document = 1 log entry "_score": null, "_source": { • Contains "field : value" pairs -

UPTEC F 18029 Examensarbete 30 hp Juni 2018 Investigation and Implementation of a Log Management and Analysis Framework for the Treatment Planning System RayStation Elias Norrby Abstract Investigation and Implementation of a Log Management and Analysis Framework for the Treatment Planning System RayStation Elias Norrby Teknisk- naturvetenskaplig fakultet UTH-enheten The purpose of this thesis is to investigate and implement a framework for log management and analysis tailored to the treatment planning system (TPS) Besöksadress: RayStation. A TPS is a highly advanced software package used in radiation Ångströmlaboratoriet Lägerhyddsvägen 1 oncology clinics, and the complexity of the software makes writing robust code Hus 4, Plan 0 challenging. Although the product is tested rigorously during development, bugs are present in released software. The purpose of the the framework is to allow the Postadress: RayStation development team insight into errors encountered in clinics by Box 536 751 21 Uppsala centralizing log file data recorded at clinics around the world. Telefon: A framework based on the Elastic stack, a suite of open-source products, is 018 – 471 30 03 proposed, addressing a set of known issues described as the access problem, the Telefax: processing problem, and the analysis problem. Firstly, log files are stored locally on 018 – 471 30 00 each machine running RayStation, some of which may not be connected to the Internet. Gaining access to the data is further complicated by legal frameworks Hemsida: such as HIPAA and GDPR that put constraints on how clinic data can be handled. http://www.teknat.uu.se/student The framework allows for access to the files while respecting these constraints. -

Thank you for your interest. Contents 1 The Hitchhiker’s Guide to Packaging" Documentation, Release 1.0 2 Contents CHAPTER 1 Table of Contents Quick Start Here’s how to create a new project, which we’ll call TowelStuff. 1. Lay out your project The smallest python project is two files. A setup.py file which describes the metadata about your project, and a file containing Python code to implement the functionality of your project. In this example project we are going to add a little more to the project to provide the typical minimal layout of a project. We’ll create a full Python package, a directory with an __init__.py file, called towelstuff/. This anticipates future growth as our project’s source code is likely to grow beyond a single module file. We’ll also create a README.txt file describing an overview of your project, and a LICENSE.txt file containing the license of your project. -

The Jumpgate Definitive Guide
THE JUMPGATE DEFINITIVE GUIDE Compiled by: Odiche Special Thanks to: NETDEVIL© NewDawn IkeProf RazorKiss Lady Dracoe SpaceDrake Zalty’s And all the Pilots I have forgotten to thank! FACTIONS Solrain: Medium-fast ships, heavy, fast-recharging shields. A little light on firepower, lots of flexibility in ship loadout because of a large number of MODx slots. (MODx are worth reading up on in JOSSH). All Solrain ships have buckets of cargo space... the Solrain Fighter-class ship, the Intensity can carry a full set of equipment in it's hold to re-equip a downed squadmate. The Solrain Bomber and Medium Fighter are top-of-the-line, and they have a good Light Transport as well. Solrain ships are fairly forgiving for a new pilot; the glut of Flashfire MODxes they can equip can ensure their survival in situations where any other ship would be gunned down before it could escape. Solrain ships often utilize hit and run techniques in combat to gain the maximum advantage from their fast-recharging shields. Solrain ships can generally re-equip to a fairly good degree from their home stations. Solrain are typically RPed (Roleplayed) as greedy, profiteering traders. Which they are. Assassins, Mercenaries, Pirates, Traders, or Factionalists. To piss off a Solrain pilot, call him a Smurf. Quantar: Usually have the fastest ships in a given class. They also have a medium load- out of MODx slots. Quantar ships rely on maneuvrability to evade incoming fire; the Quantar fighters, the Typhoon, is an ideal wolf-pack ship. Their speed can carry them out of most trouble; only scouts or an Intensity can really catch them up, and if you are a skilled pilot, you can evade and escape from those also.
