#Marzano iobserve update#

Update IObserve after you added or removed DOM elements to the page.Дestroys the instance, unsetting instance variables and removing listeners.ДЇree up some memory. Make IObserve to re-check the DOM for elements elements in the page. You can call the following methods on any instance of IObserve. Arguments: DOM element, intersection observer entry, iobserve instance. Arguments: DOM element, intersection observer entry, iobserve instance.ДЄ callback function which is called whenever an element exits the viewport. It overrides threshold when passed.ДЄ callback function which is called whenever an element enters the viewport. You can use it when you need to have different thresholds for the scrolling area. It maps directly to the rootMargin property of IntersectionObserver ( read more), so it must be a string with a syntax similar to the CSS margin property. Similar to threshold, but accepting multiple values and both px and % units. The CSS selector of the elements to load lazily.ДЄ number of pixels representing the outer distance off the scrolling area from which to start loading the elements. Var aIObserve = new IObserve ( ) OptionsДЇor every instance of IObserve you can pass in some options, to alter its default behaviour. The most common usage of IObserve constructor is to pass only the options object (see 'options' in the next section). The option object for this instance of IObserve The new IObserve() instruction you execute on your page can take two parameters: Parameter Works with RequireJS module loader, ~0.5kb smaller than UMD versionД®xports IObserve so you can import it in your project both using and a bundler like WebPack or Rollup Works as in-page, ~0.5kb smaller than UMD version IIFE (Immediately Invoked Function Expression) Works pretty much everywhere, even in common-js contexts The evaluaton results can be found at the lbl-results branch in the results folder.You can find and use different bundles. Before reconfiguring the planning service a new scenario may be chosen by editing the config file.

iobserve-setup-planning can be used to (re)configure only the planning service while adaptation and execution keep running.

iobserve-run-planning, iobserve-run-adaptation, and iobserve-run-execution can be used to start the different services indepentently.

shutdown-kube-jpetstore terminates the deployed kubernetes instances.ДЄs an alternative to the iobserve-run-all you can use the following scripts:.

The planning service will send out the models from its working directory.

iobserve-run-all starts planning, adaptation, and execution services and finishes them after a given time.

Depending on the scenario runtime and redeployment models are inserted to the planning's working directory.

iobserve-setup sets up the working directories of the different services, creates configuration files with concrete paths instead of placeholders, and modifies the planning's main method to mock the actual planning and just send out predefined models.

startup-kube-jpetstore.sh depending on the scenario from the config file it creates an initial JPetStore deployment.The following scripts are included and should be executed in the given order: Currently migration, replication, and dereplication are possible scenarios. Set the SCENARIO variable to choose the scenario you want to execute. Use the config file to set the paths to your working directory and docker repository they differ from the preset values.Before executing the evaluation scripts take a look at the config file: We recommend to use watch kubectl get to watch services, deployments, and pods while executing the different scripts. The included correspondence model maps the PCM model components to the deployable images.ДЄ number of scripts can be used to execute the evaluation. The further represents the JPetStore's present architecture and the latter represents its intended architecture. The scenarios folder contains a runtime and a redeployment model for each evaluated adaptation scenario as they would result from iObserve's planning phase.These files contain placeholders for concrete paths. The iobserve folder contains dummy configuration files for iObserve's planning, adaptation, and execution services.They are used to create an initial JPetStore deployment. The kubernetes folder contains different kubernetes configurations for different scenarios.This repository contains PCM models of the JPetstore to evaluate the execution of system adaptations on a kubernetes cluster.
