Introduction Cacti: Uses RRDtool, PHP and stores data in MySQL. It supports the use of SNMP and graphics with RRDtool. “Cacti is a complete frontend to RRDTool, it stores all of the necessary information to create graphs and populate them with data in a MySQL database. The frontend is completely PHP driven. Along with being able to maintain Graphs, Data Sources, and Round Robin Archives in a database, cacti handles the data gathering. There is also SNMP support for those used to creating traffic graphs with MRTG.” Introduction • A tool to monitor, store and present network and system/server statistics • Designed around RRDTool with a special emphasis on the graphical interface • Almost all of Cacti's functionality can be configured via the Web. • You can find Cacti here: http://www.cacti.net/ Getting RRDtool • Round Robin Database for time series data storage • Command line based • From the author of MRTG • Made to be faster and more flexible • Includes CGI and Graphing tools, plus APIs • Solves the Historical Trends and Simple Interface problems as well as storage issues Find RRDtool here:http://oss.oetiker.ch/rrdtool/ RRDtool Database Format General Description 1. Cacti is written as a group of PHP scripts. 2. The key script is “poller.php”, which runs every 5 minutes (by default).

  • Masked Graph Modeling for Molecule Generation ✉ Omar Mahmood 1, Elman Mansimov2, Richard Bonneau 3 & Kyunghyun Cho 2
    ARTICLE https://doi.org/10.1038/s41467-021-23415-2 OPEN Masked graph modeling for molecule generation ✉ Omar Mahmood 1, Elman Mansimov2, Richard Bonneau 3 & Kyunghyun Cho 2 De novo, in-silico design of molecules is a challenging problem with applications in drug discovery and material design. We introduce a masked graph model, which learns a dis- tribution over graphs by capturing conditional distributions over unobserved nodes (atoms) and edges (bonds) given observed ones. We train and then sample from our model by iteratively masking and replacing different parts of initialized graphs. We evaluate our 1234567890():,; approach on the QM9 and ChEMBL datasets using the GuacaMol distribution-learning benchmark. We find that validity, KL-divergence and Fréchet ChemNet Distance scores are anti-correlated with novelty, and that we can trade off between these metrics more effec- tively than existing models. On distributional metrics, our model outperforms previously proposed graph-based approaches and is competitive with SMILES-based approaches. Finally, we show our model generates molecules with desired values of specified properties while maintaining physiochemical similarity to the training distribution. 1 Center for Data Science, New York University, New York, NY, USA. 2 Department of Computer Science, Courant Institute of Mathematical Sciences, New ✉ York, NY, USA. 3 Center for Genomics and Systems Biology, New York University, New York, NY, USA. email: [email protected] NATURE COMMUNICATIONS | (2021) 12:3156 | https://doi.org/10.1038/s41467-021-23415-2 | www.nature.com/naturecommunications 1 ARTICLE NATURE COMMUNICATIONS | https://doi.org/10.1038/s41467-021-23415-2 he design of de novo molecules in-silico with desired prop- enable more informative comparisons between models that use Terties is an essential part of drug discovery and materials different molecular representations.

  • Observing the Clouds: a Survey and Taxonomy of Cloud Monitoring Jonathan Stuart Ward† and Adam Barker*†
    Ward and Barker Journal of Cloud Computing: Advances, Systems and Applications (2014) 3:24 DOI 10.1186/s13677-014-0024-2 RESEARCH Open Access Observing the clouds: a survey and taxonomy of cloud monitoring Jonathan Stuart Ward† and Adam Barker*† Abstract Monitoring is an important aspect of designing and maintaining large-scale systems. Cloud computing presents a unique set of challenges to monitoring including: on-demand infrastructure, unprecedented scalability, rapid elasticity and performance uncertainty. There are a wide range of monitoring tools originating from cluster and high-performance computing, grid computing and enterprise computing, as well as a series of newer bespoke tools, which have been designed exclusively for cloud monitoring. These tools express a number of common elements and designs, which address the demands of cloud monitoring to various degrees. This paper performs an exhaustive survey of contemporary monitoring tools from which we derive a taxonomy, which examines how effectively existing tools and designs meet the challenges of cloud monitoring. We conclude by examining the socio-technical aspects of monitoring, and investigate the engineering challenges and practices behind implementing monitoring strategies for cloud computing. Keywords: Cloud computing; Monitoring Introduction most accepted description of the general properties of Monitoring large-scale distributed systems is challeng- cloud computing comes from the US based National Insti- ing and plays a crucial role in virtually every aspect of tution of Standards and Technology (NIST) and other a software orientated organisation.

  • Operational Semantics with Hierarchical Abstract Syntax Graphs*
    Operational Semantics with Hierarchical Abstract Syntax Graphs* Dan R. Ghica Huawei Research, Edinburgh University of Birmingham, UK This is a motivating tutorial introduction to a semantic analysis of programming languages using a graphical language as the representation of terms, and graph rewriting as a representation of reduc- tion rules. We show how the graphical language automatically incorporates desirable features, such as a-equivalence and how it can describe pure computation, imperative store, and control features in a uniform framework. The graph semantics combines some of the best features of structural oper- ational semantics and abstract machines, while offering powerful new methods for reasoning about contextual equivalence. All technical details are available in an extended technical report by Muroya and the author [11] and in Muroya’s doctoral dissertation [21]. 1 Hierarchical abstract syntax graphs Before proceeding with the business of analysing and transforming the source code of a program, a com- piler first parses the input text into a sequence of atoms, the lexemes, and then assembles them into a tree, the Abstract Syntax Tree (AST), which corresponds to its grammatical structure. The reason for preferring the AST to raw text or a sequence of lexemes is quite obvious. The structure of the AST incor- porates most of the information needed for the following stage of compilation, in particular identifying operations as nodes in the tree and operands as their branches. This makes the AST algorithmically well suited for its purpose. Conversely, the AST excludes irrelevant lexemes, such as separators (white-space, commas, semicolons) and aggregators (brackets, braces), by making them implicit in the tree-like struc- ture.

    Install Cacti (Network Monitoring) on RHEL/CentOS 7.x Cacti tool is an open source web based network monitoring and system monitoring graphing solution for IT business. Cacti enables a user to poll services at regular intervals to create graphs on resulting data using RRDtool. Generally, it is used to graph time-series data of metrics such as network bandwidth utilization, CPU load, running processes, disk space etc. Cacti Required Packages: The Cacti required following packages to be installed on your Linux operating systems like RHEL / CentOS . Apache: A Web server to display network graphs created by PHP and RRDTool. MySQL: A Database server to store cacti information. PHP: A script module to create graphs using RRDTool. PHP-SNMP: A PHP extension for SNMP to access data. NET-SNMP: A SNMP (Simple Network Management Protocol) is used to manage network. RRDTool: A database tool to manage and retrieve time series data like CPU load, Network Bandwidth etc. Installing Cacti Required Packages on RHEL/CentOS First, we need to install following dependency packages one-by-one using YUM package manager tool. Here, you need to install and enable EPEL Repository. [root@ns1 ~]# yum install epel-release Install httpd server: # yum -y install httpd httpd-devel Start and enable httpd server # systemctl enable httpd # systemctl start httpd Check status of httpd server to make sure it’s running [root@ns1 ~]# systemctl status httpd ● httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled)
