Tavoitteena oli helpot- taa monitorointijärjestelmän käyttöönottoa. Työ tehtiin käytettävien ohjelmistojen dokumen- taation ja käytännön tekemisellä opittujen asioiden pohjalta. Insinöörityön alussa käytiin läpi työssä käytettyjä teknologioita. Tämän jälkeen käytiin läpi monitorointi järjestelmän konfiguraatio ja käyttöönotto. Seuraavaksi tutustuttiin PromQL-ha- kukieleen, jonka jälkeen näytettiin kuinka pystyttää valvontamonitori ja hälytykset sähköpos- timuistutuksella. Työn lopussa käydään läpi kuinka monitorointijärjestelmässä saatua dataa analysoidaan ja mietitään miten monitorointijärjestelmää voisi parantaa.

Eventindex Monitoring
BigData tools for the monitoring of the ATLAS EventIndex Evgeny Alexandrov1, Andrei Kazymov1, Fedor Prokoshin2, on behalf of the ATLAS collaboration 1Joint Institute for Nuclear Research, Dubna, Russia. 2Centro Científico Tecnológico de Valparaíso-CCTVal, Universidad Técnica Federico Santa María. GRID Conference at JINR 12 September 2018 Introduction • The EventIndex is the complete catalogue of all ATLAS events, keeping the references to all files that contain a given event in any processing stage. • The ATLAS EventIndex collects event information from data both at CERN and Grid sites. • It uses the Hadoop system to store the results, and web services to access them. • Its successful operation depends on a number of different components. • Each component has completely different sets of parameters and states and requires a special approach. Monitoring Components Prodsys EIOracle ??? Event Picking Tests XML ORACLE? Old Monitoring System based on Kibana Disadvantages of Kibana Slow dashboard retrieving time: - for two days period: 15 seconds; - for 7 days period: 1 minute 30 seconds; - for a longer periods: it may take tens of minutes and eventually get stuck. Not very comfortable way of editing the dashboard’s page Grafana Grafana is one of the most popular packages for visualizing monitoring data. Uses modern technologies: - back-end is written using Go programming language; - front-end is written on typescript and uses angular approach. The following datasources are officially supported: Graphite InfluxDB MySQL Elasticsearch OpenTSDB Postgres CloudWatch Prometheus Microsoft SQL Server (MSSQL) InfluxDB InfluxDB is InfluxData's open source time series database designed to handle high write and query loads. Uses modern technologies: - it is written on GO; - It has the possibility of working in cluster mode; - availability of libraries for a large number of programming languages (Python, JavaScript, PHP, Haskell and others); - SQL-like query language, with which you can perform various operations with time series (merging, splitting). -
Monitoring with Influxdb and Grafana
Monitoring with InfluxDB and Grafana Andrew Lahiff STFC RAL ! HEPiX 2015 Fall Workshop, BNL Introduction Monitoring at RAL • Like many (most?) sites, we use Ganglia • have ~89000 individual metrics • What’s wrong with Ganglia? Problems with ganglia • Plots look very dated Problems with ganglia • Difficult & time-consuming to make custom plots • currently use long, complex, messy Perl scripts • e.g. HTCondor monitoring > 2000 lines Problems with ganglia • Difficult & time-consuming to make custom plots • Ganglia UI for making customised plots is restricted & doesn’t give good results Problems with ganglia • Ganglia server has demanding host requirements • e.g. we store all rrds in a RAM disk • have problems if trying to use a VM • Doesn’t handle dynamic resources well • Occasional problems with gmond using too much memory, affecting other processes on machines • Not really suitable for Ceph monitoring A possible alternative • InfluxDB + Grafana • InfluxDB is a time-series database • Grafana is a metrics dashboard • originally a fork of Kibana • can make plots of data from InfluxDB, Graphite, others… • Very easy to make (nice) plots • Easy to install InfluxDB • Time series database written in Go • No external dependencies • SQL-like query language • Distributed • can be run as a single node • can be run as a cluster for redundancy & performance (not suitable for production use yet) • Data can be written in using REST, or an API (e.g. Python) • or from collectd or graphite InfluxDB • Data organised by time series, grouped together into databases • Time series have zero to many points • Each point consists of: • time - the timestamp • a measurement (e.g. -
Solution Deploying Elasticsearch on Kubernetes Using
Solution Guide Deploying Elasticsearch on Kubernetes using OpenEBS Contents Part 1 - Before starting Part 2 - Preconfiguration Part 3 - Getting Started with OpenEBS Part 4 - Installing Kudo Operator Part 5 - Installing ElasticSearch using Kudo Part 6 - Installing Kibana Part 7 - Installing Fluentd-ES Part 8 - Monitoring Elastic search 01 www.mayadata.io Overview Elasticsearch is a distributed, free and open search and analytics engine for all types of data, including textual, numerical, geospatial, structured, and unstructured. Elasticsearch is built on Apache Lucene and was first released in 2010 by Elasticsearch N.V. (now known as Elastic). Known for its simple REST APIs, distributed nature, speed, and scalability, Elasticsearch is the central component of the Elastic Stack, a set of free and open tools for data ingestion, enrichment, storage, analysis, and visualization. Commonly referred to as the ELK Stack (after Elasticsearch, Logstash, and Kibana), the Elastic Stack now includes a rich collection of lightweight shipping agents known as Beats for sending data to Elasticsearch.[1]. This guide explains the basic installation for Elasticsearch operators on OpenEBS Local PV devices using KUDO. We will be installing Fluentd and Kibana to form the EFK stack. The guide will also provide a way to monitor the health of Elasticsearch using Prometheus and Grafana. Before starting You require an existing Kubernetes cluster. Kubernetes provides platform abstraction, cloud-native software runs, and behaves the same way on a managed Kubernetes service like AWS EKS, Google Cloud GKE, Microsoft AKS, DigitalOcean Kubernetes Service, or self-managed based on Red Hat OpenShift and Rancher. You can also use kubeadm, kubespray, minikube. -
The Open-‐Source Monitoring Landscape
The Open-Source Monitoring Landscape Michael Merideth Sr. Director of IT, VictorOps [email protected], @vo_mike My History and Background • Working in IT since the mid 90’s • Mostly at startups in the Colorado Front Range area • Along for the ride during the “dot com boom” • Build my career using open-source tools Since the 90’s now, there’s been a sharp division in tools and methodology between the enterprise space and the startup and small business communi;es. Obviously, smaller businesses, especially in the tech sector, were early and eager adopters of open- source technology, and much quicker to learn to rely on open-source tool chains in business-cri;cal applica;ons. Up at the enterprise level, at the public companies, they’re only now fully-embracing Linux as a business-cri;cal tool, and I think that’s largely because “the enterprise” is star;ng to be defined by companies that either came up in the dot com era, like Google, or built the dot com era, like Sun, or Dell, or let’s say RedHat. So, the “enterprise” had their toolchain, built on commercial solu;ons like HPUX and OpenView and so on, and the startup community, the “dot com” community had a completely different toolchain, based on Linux, based on open standards and protocols, built with open-source components like GNU, and Apache, and ISC Bind and so on. I’m lucky enough that I’ve been able to spend my career in the startup sphere, working with that open-source toolchain. I started working in IT in the mid 90’s in the Colorado front range, and I’ve spent my ;me since then working for and consul;ng at early-stage startups and other “non enterprise” shops. -
