Grafana

گرافنا Grafana یک ابزار متن باز برای تحلیل و بررسی database و مانیتورینگ است. این نرم افزار می‌تواند متریک‌ها را خوانده و آنها را خیلی ساده و روشن در قالب نمودارهایی کارآمد و جذاب نمایش دهد. لازم به ذکر است که از پیش نمودارهای بسیاری برای آن فراهم شده است. کاربران نیز داشبوردهای طراحی شده‌ی خود را به صورت رایگان یا پولی در اختیار دیگران قرار می‌دهند. Grafana به تمامی منابع داده ی ممکن متصل می شود و به طور معمول به دیتا بیس هایی مانند Graphite، Prometheus، Influx DB، ElasticSearch، MySQL، PostgreSQL و … قابل ارجاع است. به صورت کلی نرم افزار گرافانا مرکزی برای جمع آوری داده‌ها از سایر سیستم‌های مانیتورینگ یا خود سیستم‌ها است. می‌توان سامانه‌ها، تجهیزات و سیستم‌ها را توسط سایر ابزارها جمع آوری کرده و در یک پنل کاملا حرفه‌ای و جذاب بصری در کنار یکدیگر قرار داد تا در نهایت به بهترین شکل آنها را به نمایش گذاشت.

Description

Welcome to my course on GrafanaGrafana is an analytics platform for all of your metrics. Grafana allows you to query, visualize, alert on and understand your metrics no matter where they are stored. Create, explore, and share dashboards with your team and foster a data driven culture. Trusted and loved by the community.This is a Learn by example course, where I demonstrate all the concepts discussed so that you can see them working, and you can try them out for yourself as well.With this course, comes accompanying documentation that you can access for free. You will then be able to match what you see in the videos and copy/paste directly from my documentation and see the same result.

In this course we will,Install Grafana from PackagesCreate a domain name, install an SSL certificate and change the default portExplore the Graph, Stat, Gauge, Bar Gauge, Table, Text, Heatmap and Logs PanelsCreate many different types of Data Sources from MySQL, Zabbix, InfluxDB, Prometheus and LokiWe will configure their various collection processes such as MySQL Event Scheduler, Telegraf, Node Exporters, SNMP agents and PromtailWe will look at graphing Time Series data versus Non Time Series dataWe will also install dashboards for each of the Data Sources, experimenting with community created dashboards plus experimenting with our ownWe will monitor SNMP Devices using Telegraf Agent and InfluxDB Data SourcesSetup Elasticsearch with Filebeat and Metricbeat servicesWe will create Annotation Queries and link the Log and Graphs panels togetherWe will look at Dynamic Dashboard Variables, Dynamic Tables and GraphsWe will look at creating Value Groups/Tags and how to use them with different kinds of data sourcesWe will set up Alerting Channels/Contact Points and understand the different alerting options, configure an example to detect offline SNMP devices and demonstrate receiving email alerts via a local SMTP serverAt the end of the course, you will have your own dedicated working Grafana Server, which will be in the cloud, with SSL, a domain name, with many example Data Sources and collectors configured, that you can call your own, ready for you to take it to the next level.Once again, this is a Learn by example course, with all the example commands available for you to copy and paste. I demonstrate them working, and you will be able to do that to. You are now ready to continue.Thanks for taking part in my course, and i’ll see you there.
