2022-04-04refactor(web/ui): Fix compatibility with new APIFabian Mastenbroek
This change updates the web interface in React to be compatible with the new API written in Kotlin. Several changes have been made in the new API to ensure consistency.
2022-04-04refactor(web/runner): Update runner to use new web clientFabian Mastenbroek
This change updates the web runner implementation to use the new API client introduced in the previous commit.
2022-04-04feat(web/client): Add separate web client implementationFabian Mastenbroek
This change implements a simple client for the OpenDC REST API into a separate module. This allows other users to use this module as well.
2022-04-04fix(web/api): Support dynamic JSON type selection for DBFabian Mastenbroek
This change adds support for dynamically selecting the appropriate JSON type for the current database. For Postgres, this will be the JSONB type, while for H2 this is either the BLOB or JSON type.
2022-04-04feat(web/api): Initial API implementation in KotlinFabian Mastenbroek
This change adds the initial implementation of the new API server in Kotlin, replacing the old API written in Python. The implementation uses Quarkus, RESTEasy, and Hibernate to implement the new API endpoints. The reason for replacing the old API server is unifying the build and deployment toolchains, reducing the number of technologies necessary to work with OpenDC. Furthermore, we envision bundling the entire OpenDC project into a single distributions, allowing users to launch their own deployment trivially.
2022-04-04feat(web/proto): Design unified communication protocolFabian Mastenbroek
This change adds a unified communication protocol in form of the module opendc-web-proto which contains the classes that form the communication protocol of OpenDC's API v2. By having the protocol in a separate module, we can utilize the classes in both server and client.

2022-02-18build: Remove opendc-platform moduleFabian Mastenbroek
This change removes the opendc-platform module from the project. This module represented a Java platform which was previously used for sharing a set of dependency versions between subprojects. However, with the version catalogue that was added by Gradle, we currently do not use the platform anymore.

2022-02-17fix(web/ui): Fix creation of topologiesFabian Mastenbroek
This change fixes an issue with the creation of topologies in the frontend. Previously, the frontend relied on Redux to update the state. However, since we removed the reliance on Redux, we also need to create a new topology using the functions from React Query to actually send a request to the API server.
2022-02-17ci: Fix API deployment using Docker ComposeFabian Mastenbroek
This change updates the Docker Compose configuration to properly deploy the API server, by passing the necessary Auth0 information to it.
2022-02-17fix(web/runner): Support custom audience in web runnerFabian Mastenbroek
This change adds support for custom audience values in the web runner. If the audience used by the user is different from the default value (https://api.opendc.org/v2/), then the runner fails to obtain a valid access token for the API.
2022-02-15refactor: Update OpenTelemetry to version 1.11Fabian Mastenbroek
This change updates the OpenDC codebase to use OpenTelemetry v1.11, which stabilizes the metrics API. This stabilization brings quite a few breaking changes, so significant changes are necessary inside the OpenDC codebase.

2021-10-25perf(telemetry): Prevent allocations during collection cycleFabian Mastenbroek
This change redesigns the ComputeMonitor interface to reduce the number of memory allocations necessary during a collection cycle.
2021-10-25perf(compute): Redesign VM interference algorithmFabian Mastenbroek
This change redesigns the virtual machine interference algorithm to have a fixed memory usage per `VmInterferenceModel` instance. Previously, for every interference domain, a copy of the model would be created, leading to OutOfMemory errors when running multiple experiments at the same time.
2021-10-03refactor(simulator): Migrate to flow-based simulationFabian Mastenbroek
This change renames the `opendc-simulator-resources` module into the `opendc-simulator-flow` module to indicate that the core simulation model of OpenDC is based around modelling and simulating flows. Previously, the distinction between resource consumer and provider, and input and output caused some confusion. By switching to a flow-based model, this distinction is now clear (as in, the water flows from source to consumer/sink).
2021-09-28refactor(telemetry): Do not require clock for ComputeMetricExporterFabian Mastenbroek
This change drops the requirement for a clock parameter when constructing a ComputeMetricExporter, since it will now derive the timestamp from the recorded metrics.

2021-09-21feat(trace): Add support for writing tracesFabian Mastenbroek
This change adds a new API for writing traces in a trace format. Currently, writing is only supported by the OpenDC VM format, but over time the other formats will also have support for writing added.
2021-09-19refactor(capelin): Make workload sampling model extensibleFabian Mastenbroek
This change updates the workload sampling implementation to be more flexible in the way the workload is constructed. Users can now sample multiple workloads at the same time using multiple samplers and use them as a single workload to simulate.
2021-09-19refactor(capelin): Support flexible topology creationFabian Mastenbroek
This change adds support for creating flexible topologies by creating a TopologyFactory interface that is responsible for configuring the hosts of a compute service.
2021-09-19refactor(capelin): Extract common code out of Capelin experimentsFabian Mastenbroek
This change creates a new module for doing simulations with virtual machine workloads. We have found that a lot of code in the Capelin experiments code is being re-used by non-experiment modules.
2021-09-17refactor(telemetry): Standardize SimHost metricsFabian Mastenbroek
This change standardizes the metrics emitted by SimHost instances and their guests based on the OpenTelemetry semantic conventions. We now also report CPU time as opposed to CPU work as this metric is more commonly used.
2021-09-17refactor(telemetry): Standardize compute scheduler metricsFabian Mastenbroek
This change updates the OpenDC compute service implementation with multiple meters that follow the OpenTelemetry conventions.
2021-09-17refactor(telemetry): Create separate MeterProvider per service/hostFabian Mastenbroek
This change refactors the telemetry implementation by creating a separate MeterProvider per service or host. This means we have to keep track of multiple metric producers, but that we can attach resource information to each of the MeterProviders like we would in a real world scenario.
2021-09-10refactor(compute): Integrate fault injection into compute simulatorFabian Mastenbroek
This change moves the fault injection logic directly into the opendc-compute-simulator module, so that it can operate at a higher abstraction. In the future, we might again split the module if we can re-use some of its logic.
2021-09-10build(ui): Update dependenciesFabian Mastenbroek
This change updates the dependencies of the OpenDC frontend module.
2021-09-07refactor(capelin): Restructure input reading classesFabian Mastenbroek
2021-09-07build(web): Resolve kotlin-reflect incompatibilityFabian Mastenbroek
This change addresses an incompatibility issue with the kotlin-reflect transitive dependency in the opendc-web-runner module.
2021-09-07refactor(capelin): Move metric collection outside Capelin codeFabian Mastenbroek
This change moves the metric collection outside the Capelin codebase in a separate module so other modules can also benefit from the compute metric collection code.
2021-09-07feat(capelin): Report up/downtime metrics in experiment monitorFabian Mastenbroek

2021-09-02refactor(trace): Implement trace API for WTF readerFabian Mastenbroek
This change updates the WTF trace reader to support the new streaming trace API.
2021-09-02refactor(format): Remove environment reader from format libraryFabian Mastenbroek
This change removes the environment reader from the format library since they are highly specific for the particular experiment. In the future, we hope to have a single format to setup the entire datacenter (perhaps similar to the format used by the web runner).

This change upgrades the OpenTelemetry dependency to version 1.5, which contains various breaking changes in the metrics API.
2021-08-22refactor(compute): Update FilterScheduler to follow OpenStack's NovaFabian Mastenbroek
This change updates the FilterScheduler implementation to follow more closely the scheduler implementation in OpenStack's Nova. We now normalize the weights, support many of the filters and weights in OpenStack and support overcommitting resources.
2021-08-17feat(ui): Add context selectorsFabian Mastenbroek
This change adds context selectors for the OpenDC frontend where the user can select different projects, portfolios or topologies from the context selection bar.
