+# prometheus-modbus-exporter
+
+Prometheus exporter for scraping metrics via modbus based protocol.
+
+## Intro
+
+This chart bootstraps a [modbus_exporter](https://github.com/RichiH/modbus_exporter) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
+
+The serviceMonitor objects are created for Prometheus Operator.
+
+## Configuration
+
+The configuration of the modbus_exporter can be provided either via helm's custom values, or via an already existing (independently managed) configMap.  
+Either way, every time the configuration is getting updated, the modbus_exporter is getting restarted in order to fetch it. This is done using sidecar reloader: <https://github.com/Pluies/config-reloader-sidecar>.
+
+## Tests
+
+This setup has been tested with both real unit (Janitza Power Analizer UMG series) as well as using an simulator <https://www.modbustools.com/download.html>.  
+Other simulators (fully free) exist as well:
+
+1. the one included as part of the test (fake server) in the <https://github.com/RichiH/modbus_exporter/blob/main/tests/fake_server/main.go>, which uses <https://github.com/tbrandon/mbserver> (golang).  
+2. Many others, like pymodslave, based on py module: <https://github.com/ljean/modbus-tk>, which has its own demo simulator as well.  
+
+## Notes
+
+There are 4 types of read registries, hence 4 read function codes (1,2,3,4).  
+Don't forget to prefix (first digit) your registry with the required function.  
+Your address should be always 6 digits.  
+E.g. for holding registry 22, the address is: 300022  (where the 3 denotes the holding registry function).  
+More on Modbus function codes: <https://ozeki.hu/p_5873-modbus-function-codes.html>
+
+## Prerequisites
+
+- Kubernetes 1.10+ with Beta APIs enabled
+- Helm 3+
+
+## Get Repository Info
+
+```console
+helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
+helm repo update
+```
+
+_See [helm repository](https://helm.sh/docs/helm/helm_repo/) for command documentation._
+
+## Install Chart
+
+```console
+helm install [RELEASE_NAME] prometheus-community/prometheus-modbus-exporter
+```
+
+_See [configuration](## Configuring) below._
+
+_See [helm install](https://helm.sh/docs/helm/helm_install/) for command documentation._
+
+## Uninstall Chart
+
+```console
+helm uninstall [RELEASE_NAME]
+```
+
+This removes all the Kubernetes components associated with the chart and deletes the release.
+
+_See [helm uninstall](https://helm.sh/docs/helm/helm_uninstall/) for command documentation._
+
+## Upgrading Chart
+
+```console
+helm upgrade [RELEASE_NAME] [CHART] --install
+```
+
+## Configuring
+
+See [Customizing the Chart Before Installing](https://helm.sh/docs/intro/using_helm/#customizing-the-chart-before-installing). To see all configurable options with detailed comments, visit the chart's [values.yaml](./values.yaml), or run these configuration commands:
+
+```console
+helm show values prometheus-community/prometheus-modbus-exporter
+```
+
+For more information please refer to the [modbus_exporter](https://github.com/RichiH/modbus_exporter) documentation.
