Rede de computadores são elementos fundamentais no processo de comunicação. Esses componentes exigem o acompanhamento constante de suas tarefas e são administrados por sistemas de informações que coletam os dados diariamente, para orientar os analistas de suporte na correção das falhas na infraestrutura: velocidade na transmissão de dados, desempenho de processadores, memorias de trabalho e armazenamento. E a ferramenta utilizada na gestão de recursos de rede de computadores é o protocolo SNMP. As infraestruturas de geração de energia elétrica também são elementos complexos e necessitam de acompanhamento. São utilizados sistemas de informação que disponibilizam dados para os usuários e responsáveis técnicos para avaliarem o funcionamento e corrigir as possíveis falhas: por descargas atmosféricas, falhas de equipamentos, colisão, interrupção do fornecimento de energia elétrica. Este trabalho tem como objetivo desenvolver um sistema de monitoramento on line para sistema de microgeração fotovoltaica utilizando o protocolo de rede de computadores Single Network Management Protocol (SNMP) para realizar a interface de comunicação com as variáveis de medições elétricas. O desenvolvimento do projeto compõe dois componentes: hardware e software. O software é um sistema Web. Nos componentes de hardware foram utilizados cinco microcontroladores Atmel AVR, (Arduino) todos ligados à sensores e programados para a leitura de geração e consumo de energia elétrica. Todos os experimentos foram realizados na central de microgeração distribuída fotovoltaica (MGD-PV) do Sítio Modelo da fazenda Lageado e no Laboratório de Energias Renováveis do Departamento de Engenharia Rural, nas Faculdades de Ciências Agronômicas da UNESP, campus de Botucatu. O laboratório de Energias Renováveis é o Servidor do sistema e as distâncias são muito variáveis entre todos os microcontroladores, de 32 metros a 260 metros e para realizar o processo de coleta dos dados nos diversos pontos e suprir essa distância foi necessário a construção e configuração de uma infraestrutura de comunicação baseada nas tecnologias ZigBee, para conectar os cincos microcontroladores. Os componentes de hardware e de software apresentaram rendimentos satisfatórios no processamento das informações através da interface criada pelo protocolo SNMP na comunicação e nas transmissões dos dados gerados pelos sensores, na configuração e mapeamento os objetos para construção da MIB para serem utilizados nas medições elétricas.PALAVRAS-CHAVES: Protocolo SNMP, sistemas fotovoltaicos, Arduíno, ZigBee. ON-LINE MONITORING OF A PHOTOVOLTAIC MICROGENERATION SYSTEM THROUGH THE SNMP PROTOCOLABSTRACT: Computer networks are fundamental elements in the communication process. Such components demand constant supervision of their tasks and are managed by information systems, which daily collect data to guide support analysts when correcting glitches in the infrastructure, speed of data transmission, performance of processors, working and storage memories. Protocol SNMP is the tool used for managing resources of the computer network. The infrastructures of electric energy generation are also complex elements and require monitoring. Information systems are utilized, which provide data to users and technical professionals, so they can evaluate functioning and correct possible errors, by atmospheric discharges, equipment failures, collision, interruption of the electric power supply. This work aims at developing an online monitoring system for photovoltaic microgeneration using the Single Network Management Protocol (SNMP) to perform the communication interface with the variables of electrical measurements. The project development is composed of two elements: hardware and software. The software to be use on the Web. As to hardware, we used five microcontrolers Atmel AVR, (Arduino) connected to sensors and programmed for reading the production and consumption of electric energy. All experiments were carried out at the Distributed Photovoltaic Microgeneration Central (MGD-PV) on a Model Farm and at the Renewable Energies Laboratory of the Agronomy College at UNESP, in Botucatu. The Renewable Energies Laboratory is the server of the system and the distances among all microcontrolers vary from 32 to 260 meters. Therefore, in order to collect data from several locations and neutralize such distance, we needed to build and configure a communication infrastructure based on ZigBee technologies to connect the five microcontrolers. Hardware and software components showed satisfactory performance at processing information through the interface created by the SNMP protocol regarding communication and transmission of the data generated by sensors as well as on the configuration and mapping objects for the construction of the MIB to be used in electrical measurements.KEYWORDS: SNMP protocol, photovoltaic systems, Arduíno, ZigBee.

This paper proposes a network management scheme of WSN. With embedded technology and SNMP (Simple Network Management Protocol) agent technology, an embedded SNMP agent is designed. The agent abstracts a WSN device to a virtual device as a SNMP management node. The main advantage is that the agent supports SNMP to manage the network, and diverse embedded devices can be managed identically with the conventional Internet network management. Therefore, the scheme can reduce the cost of network management and simplify the operation. Finally, by experiments, the scheme is proved to be feasible.

Proses monitoring jaringan access point terkadang membuat penyedia layanan harus selalu mendatangi titik access point untuk melakukan controlling. Tidak akan menjadi masalah apabila titik layanan access point hanya 1, namun jika dalam sekala yang cukup besar maka hal ini tentu akan menyita waktu cukup banyak. belum lagi administrator juga harus selalu mematikan dan menghidupkan perangkat guna mereset data cache nya setiap minggu. Untuk memecahkan masalah tersebut usaha yang dilakukan adalah dengan membangun sistem monitor access point menggunakan protokol sederhana yaitu dengan Simple Network Management Protocol(SNMP). Sistem monitoring jaringan access point menggunakan protokol SNMP merupakan sebuah rancangan sistem yang dapat membantu penyedia layanan access internet untuk memonitor kondisi access point di beberapa titik. Dengan adanya system monitoring ini penyedia layanan dapat melakukan controling dan monitoring jaringan berskala cukup besar tanpa harus mendatangi titik hotspot nya satu persatu.  Hasil pengujian dari sistem monitoring jaringan access point menggunakan Simple Network Management Protocol(SNMP) dapat disimpulkan bahwa sistem berjalan dengan hasil yang cukup baik dan sesuai harapan. pengujian terhadap progam juga dilakukan melalui beberapa peramban yang umum seperti  Mozilla Firefox, Microsoft Edge dan Google Chrome. Pengujian sistem juga dilakukan pada beberapa sistem operasi, yaitu windows, linux serta Android

Abstract The article focuses on process management in public administration using the specific case study of the statutory city of Ostrava. Based on the selected part of the PAPRIS methodology, the process management is verified, and conclusions from the application of information system e-SMO ("Electronic Statutory City of Ostrava") are generalized. Ostrava is third the biggest city in Czech Republic with approximately 320 thousand citizen. Article describes experiences with SW implements, which are used for model of process in public administration. Particulary at local authority of Ostrava town. Model of process is a basis for reengineering of process in state administration and preparation for implementation of big information systems. Mapping of process is providing implement and confirmation methodology to identify existing processes. Problem with its using consist in that, senior manager don’t informs, what organization is determination by processes. If are not described in given to organization current processes, or how would have had look new optimum processes, will not endeavour about reengineering successful. Procedural analysis namely offer tool and check methodology to identification current suit („ at") and it is possible him use either as instruction („ how so about to be") for reengineering function handling administrative and self-rule activities. Purpose of the article: The PAPRIS methodology was used when defining the objectives for implementation of the information system for public administration (PAPRIS - Process Approach - Public and Regional Information System). This methodology has been elaborated by one of the authors and published in a very general scheme when solving many case studies (Krajčík, 2006), (Krajčík, 2007), (Krajčík, 2013) (Krajčík, 2014). We assume that the PAPRIS is primarily a methodology with incorporated elements of procedural approach for project management in public administration information systems (PAIS). The specific supporting process of communication between the client and the e-SMO ("Electronic Statutory City of Ostrava") system has been chosen for verification. The model of supporting communication process, created by ARIS tools, is crucial, and the structure of scripts (ICM and IVR) is subsequently made. The aim of this article is to verify that the methodology is sufficient and appropriate to manage such a large project such, undoubtedly, is the e-SMO (Vlček, 2009). Methodology/methods: Defined productive and non-productive processes with their defined process cuts represent a crucial category for the process structure of IS projects. This is fully accepted by the PAPRIS methodology. Process cuts are understood, in the logic modelling according to the PAPRIS methodology, as clearly defined logic directional cuts in three-dimensional space of all project processes. The process set is systemically categorized, in a given logic directional cut, into mutually disjoint process subsets, which are characterized by this particular directional operator. The directional operator always has a clear logical allocation that is based on the construction of a process view. Theoretically, an infinite number of process views can be used. One of the important issues in a methodology for the case studies includes the size of the research sample. It is usually assumed that there is no ideal number of cases and that the number between four and ten usually provides good results. Other authors defining against any quantitative standards for any determination of the sample size of the case studies, since such an approach denies the internal logic of this methodology and the richness of the information obtained from participants in the research. Research which is carried out using case studies does not aspire on compliance with the requirement the representativeness of the sample. (Štrach, 2007). Methodology of case studies is among the established guidelines of qualitative research (Štrach, 2007). Research on using case studies in the last 30 years has seen an extraordinary increase in social-scientific research, including research on business and management (Dul, Hak, 2008). Scientific aim: The essential aim of this study is to describe the way the process cut defines a productive process and non-productive process, in accordance with the PAPRIS methodology using the specific example. While the triggering mechanism of the project production process is an event causing its own production - i.e. the specific output with added value for the customer, the project of non-productive process is caused by the project management event. Therefore, it is caused by the need to control, monitor, track, inspect, evaluate outputs, decide and regulate the project implementation. Findings: Within the support of the communication process, two examples were used to verify the methodology. The global perspective on the process was created in ARIS tools and the communication between the call centre and the client was made in Visio tools. The PAPRIS methodology is based on the concept of process variability, which has been clearly formulated. The fundamental direction of the process development, anticipated changes and the opportunity to react to them in accordance with defined objectives of the PAIS project are guaranteed.
