ProxLB meticulously gathers and analyzes a comprehensive set of resource metrics from both the cluster nodes and the running VMs. These metrics include CPU usage, memory consumption, and disk utilization, specifically focusing on local disk resources.
 
 PLB collects resource usage data from each node in the Proxmox cluster, including CPU, (local) disk and memory utilization. Additionally, it gathers resource usage statistics from all running VMs, ensuring a granular understanding of the cluster's workload distribution.
 
-Intelligent rebalancing is a key feature of ProxLB where it re-balances VMs based on their memory, disk or cpu usage, ensuring that no node is overburdened while others remain underutilized. The rebalancing capabilities of PLB significantly enhance cluster performance and reliability. By ensuring that resources are evenly distributed, PLB helps prevent any single node from becoming a performance bottleneck, improving the reliability and stability of the cluster. Efficient rebalancing leads to better utilization of available resources, potentially reducing the need for additional hardware investments and lowering operational costs.

+## How does it work?
+ProxLB is a load-balancing system designed to optimize the distribution of virtual machines (VMs) and containers (CTs) across a cluster. It works by first gathering resource usage metrics from all nodes in the cluster through the Proxmox API. This includes detailed resource metrics for each VM and CT on every node. ProxLB then evaluates the difference between the maximum and minimum resource usage of the nodes, referred to as "Balanciness." If this difference exceeds a predefined threshold (which is configurable), the system initiates the rebalancing process.
+
+Before starting any migrations, ProxLB validates that rebalancing actions are necessary and beneficial. Depending on the selected balancing mode — such as CPU, memory, or disk — it creates a balancing matrix. This matrix sorts the VMs by their maximum used or assigned resources, identifying the VM with the highest usage. ProxLB then places this VM on the node with the most free resources in the selected balancing type. This process runs recursively until the operator-defined Balanciness is achieved. Balancing can be defined for the used or max. assigned resources of VMs/CTs.
+
 ## Usage
 Running PLB is easy and it runs almost everywhere since it just depends on `Python3` and the `proxmoxer` library. Therefore, it can directly run on a Proxmox node, dedicated systems like Debian, RedHat, or even FreeBSD, as long as the API is reachable by the client running PLB.

+### Balancing
+#### General
+In general, virtual machines and containers can be rebalanced and moved around nodes in the cluster. Often, this also works without downtime without any further downtimes. However, this does **not** work with containers. LXC based containers will be shutdown, copied and started on the new node. Also to note, live migrations can work fluently without any issues but there are still several things to be considered. This is out of scope for ProxLB and applies in general to Proxmox and your cluster setup. You can find more details about this here: https://pve.proxmox.com/wiki/Migrate_to_Proxmox_VE.
+
+#### By Used Memory of VMs/CTs
+By continuously monitoring the current resource usage of VMs, ProxLB intelligently reallocates workloads to prevent any single node from becoming overloaded. This approach ensures that resources are balanced efficiently, providing consistent and optimal performance across the entire cluster at all times. To activate this balancing mode, simply activate the following option in your ProxLB configuration:
+```
+mode: used
+```
+
+Afterwards, restart the service (if running in daemon mode) to activate this rebalancing mode.
+
+#### By Assigned Memory of VMs/CTs
+By ensuring that resources are always available for each VM, ProxLB prevents over-provisioning and maintains a balanced load across all nodes. This guarantees that users have consistent access to the resources they need. However, if the total assigned resources exceed the combined capacity of the cluster, ProxLB will issue a warning, indicating potential over-provisioning despite its best efforts to balance the load.  To activate this balancing mode, simply activate the following option in your ProxLB configuration:
+```
+mode: assigned
+```
+
+Afterwards, restart the service (if running in daemon mode) to activate this rebalancing mode.

-#### Ignore VMs (tag style)
+#### Ignore VMs (Tag Style)
 <img align="left" src="https://cdn.gyptazy.ch/images/plb-rebalancing-ignore-vm.jpg"/>  In Proxmox, you can ensure that certain VMs are ignored during the rebalancing process by setting a specific tag within the Proxmox Web UI, rather than solely relying on configurations in the ProxLB config file. This can be achieved by adding the tag 'plb_ignore_vm' to the VM. Once this tag is applied, the VM will be excluded from any further rebalancing operations, simplifying the management process.
 
+### Rolling Updates
+**Warning**: This feature is still in beta! Do **NOT** use this on production systems!
+
+Rolling updates ensure that the cluster and its nodes are always up to date by integrating the pending updates from the defined system repository. With every run of the rebalancing, the executing node will also check is the ProxLB API (`proxlb_api_enable`) and the rolling update feature (`rolling_updates`) are enabled. Both ones activated, will perform the following logic:
+* Check if updates are present
+* Install updates
+* Validate if updates require a reboot:
+    * -> No Reboot:
+        * -> Done
+    * -> Reboot required:
+        * -> Set self to maintenance mode in ProxLB API
+        * -> Query all other nodes on the cluster on the ProxLB API
+        * -> Any Node in maintenance:
+            * -> Stop
+        * -> No other Node in maintenance:
+            * -> Move all VMs/CTs to other nodes
+            * -> Reboot Node
+
+Please take note, that this feature requires a patched Proxmox API file. All actions should only be performed by the Proxmox or ProxLB API. Currently, the Proxmox API does not have any method to perform and install updates. Therefore, a patched API node file is required. ProxLB will vlaidate if the needed API endpoint is needed and if missing stop the rolling update functionality. The patched API functionality can be integrated by installing the package `proxlb-addition-api.deb` and is required on **all** nodes in a cluster. This package is not listed in the regular repository because if overwrites the present file(s). This is highly WIP and should **not** be used on production systems right now!
+
+**Note: This feature requires you to activate the ProxLB API and also the package `proxlb-addition-api.deb`.**
+
+### ProxLB API
+<img align="left" src="https://cdn.gyptazy.ch/images/proxlb-api-swagger.jpg"/>
+ProxLB comes with its own API. The API is based on Python's `FastAPI` and provides additional features. The API is required when using the rolling updates feature.
+
+#### Configuration
+The API has some configuration parameters. By defalult, it listens on `0.0.0.0` and the tcp port `8008` and is from any host accessable and does not require any authentiocation yet. You may firewall or add authentications with a reverse proxy. Currently, you can define to enable it, the listener and the port.
+
+| Option | Example | Description | Default |
+|------|:------:|:------:|:------:|
+| proxlb_api_enable | 0 | Enables (1) the ProxLB own API. | `0` |
+| proxlb_api_listener | 0.0.0.0 | Defines the listener address for the ProxLB API. | `0.0.0.0` |
+| proxlb_api_port | 8008 | Defines the tcp port for the ProxLB API to listen. | `8008` |

 # Configuration
+
+## Balancing
+### By Used Memmory of VMs
+By continuously monitoring the current resource usage of VMs, ProxLB intelligently reallocates workloads to prevent any single node from becoming overloaded. This approach ensures that resources are balanced efficiently, providing consistent and optimal performance across the entire cluster at all times. To activate this balancing mode, simply activate the following option in your ProxLB configuration:
+```
+mode: used
+```
+Afterwards, restart the service (if running in daemon mode) to activate this rebalancing mode.
+
+### By Assigned Memory of VMs
+By ensuring that resources are always available for each VM, ProxLB prevents over-provisioning and maintains a balanced load across all nodes. This guarantees that users have consistent access to the resources they need. However, if the total assigned resources exceed the combined capacity of the cluster, ProxLB will issue a warning, indicating potential over-provisioning despite its best efforts to balance the load.  To activate this balancing mode, simply activate the following option in your ProxLB configuration:
+```
+mode: assigned
+```
+Afterwards, restart the service (if running in daemon mode) to activate this rebalancing mode.

Navigate to the VM you want to tag by selecting it from the left-hand navigation panel. Click on the "Options" tab to view the VM's options, then select "Edit" or "Add" (depending on whether you are editing an existing tag or adding a new one). In the tag field, enter plb_include_ followed by your unique identifier, for example, plb_include_group1. Save the changes to apply the tag to the VM. Repeat these steps for each VM that should be included in the group.

 Debian/Ubuntu: apt-get install python3-proxmoxer
 If the package is not provided by your systems repository, you can also install it by running `pip3 install proxmoxer`.
+
+### How does it work?
+ProxLB is a load-balancing system designed to optimize the distribution of virtual machines (VMs) and containers (CTs) across a cluster. It works by first gathering resource usage metrics from all nodes in the cluster through the Proxmox API. This includes detailed resource metrics for each VM and CT on every node. ProxLB then evaluates the difference between the maximum and minimum resource usage of the nodes, referred to as "Balanciness." If this difference exceeds a predefined threshold (which is configurable), the system initiates the rebalancing process.
+
+Before starting any migrations, ProxLB validates that rebalancing actions are necessary and beneficial. Depending on the selected balancing mode — such as CPU, memory, or disk — it creates a balancing matrix. This matrix sorts the VMs by their maximum used or assigned resources, identifying the VM with the highest usage. ProxLB then places this VM on the node with the most free resources in the selected balancing type. This process runs recursively until the operator-defined Balanciness is achieved. Balancing can be defined for the used or max. assigned resources of VMs/CTs.
+
+### Logging
+ProxLB uses the `SystemdHandler` for logging. You can find all your logs in your systemd unit log or in the `journalctl`. In default, ProxLB only logs critical events. However, for further understanding of the balancing it might be useful to change this to `INFO` or `DEBUG` which can simply be done in the [proxlb.conf](https://github.com/gyptazy/ProxLB/blob/main/proxlb.conf#L14) file by changing the `log_verbosity` parameter.

+| WARNING | This option provides only warning messages, which might be a problem in general but not for the application itself. |
+| CRITICAL | This option logs all critical events that will avoid running ProxLB. |
+
+### Motivation
+As a developer managing a cluster of virtual machines for my projects, I often encountered the challenge of resource imbalance. Nodes within the cluster would become unevenly loaded, with some nodes being overburdened while others remained underutilized. This imbalance led to inefficiencies, performance bottlenecks, and increased operational costs. Frustrated by the lack of an adequate solution to address this issue, I decided to develop the ProxLB (PLB) to ensure better resource distribution across my clusters.
+
+My primary motivation for creating PLB stemmed from my work on my BoxyBSD project, where I consistently faced the difficulty of maintaining balanced nodes while running various VM workloads but also on my personal clusters. The absence of an efficient rebalancing mechanism made it challenging to achieve optimal performance and stability. Recognizing the necessity for a tool that could gather and analyze resource metrics from both the cluster nodes and the running VMs, I embarked on developing ProxLB.
+
+PLB meticulously collects detailed resource usage data from each node in a Proxmox cluster, including CPU load, memory usage, and local disk space utilization. It also gathers comprehensive statistics from all running VMs, providing a granular understanding of the workload distribution. With this data, PLB intelligently redistributes VMs based on memory usage, local disk usage, and CPU usage. This ensures that no single node is overburdened, storage resources are evenly distributed, and the computational load is balanced, enhancing overall cluster performance.
+
+As an advocate of the open-source philosophy, I believe in the power of community and collaboration. By sharing solutions like PLB, I aim to contribute to the collective knowledge and tools available to developers facing similar challenges. Open source fosters innovation, transparency, and mutual support, enabling developers to build on each other's work and create better solutions together.
+
+Developing PLB was driven by a desire to solve a real problem I faced in my projects. However, the spirit behind this effort was to provide a valuable resource to the community. By open-sourcing PLB, I hope to help other developers manage their clusters more efficiently, optimize their resource usage, and reduce operational costs. Sharing this solution aligns with the core principles of open source, where the goal is not only to solve individual problems but also to contribute to the broader ecosystem.
