# Kube-Prometheus-Top [ KPtop ]
A Python tool that offers beautiful CLI monitoring based on Prometheus metrics, with Kubernetes integration through PodPortForward
Allowing you to create your own custom CLI dashboards & CLI commands with custom layouts, variables, CLI arguments !
**KPtop has been refactored to work as a general CLI monitoring tool, deprecating all hardcoded metrics & dashboards. 🚀**
# Motivation
Prometheus is widely used with different kinds of metrics - Let's make CLI monitoring more powerful with Prometheus data. ✊
## [KPtop Documentation](https://eslam-gomaa.github.io/kptop) 🍉

|**options:** [`prometheus_endpoint`, `pod_portForward`] | True |
> There are 2 options to connect KPtop to Prometheus:
1. With a Prometheus server endpoint
- Suitable if Prometheus is exposed (with an ingress for example)
2. With 'K8s pod port-forward' (Through K8s API-Server)
- Suitable if Prometheus is Not exposed (Only rechable with K8s cluster access)

# Usage
## [1] Add the Prometheus connection Environment Variables
## Example
_**Example**_
```bash
export KPTOP_CONNECTION_METHOD="pod_portForward"
export KPTOP_PROMETHEUS_POD_NAME="my-prometheus-server-0"
export KPTOP_PROMETHEUS_POD_PORT="9090"
export KPTOP_PROMETHEUS_POD_NAMESPACE="monitoring"
```
| Or
```bash
export KPTOP_CONNECTION_METHOD="prometheus_endpoint"
export KPTOP_PROMETHEUS_SERVER="http://prometheus.home-lab.com"
```
## [2] Configure the location of your dashboards & commands
Example:
```bash
export KPTOP_DEFAULT_DASHBOARDS_DIRECTORY="/Users/YOU/kptop/examples/dashboards"
export KPTOP_DEFAULT_COMMANDS_DIRECTORY="/Users/YOU/kptop/examples/dashboards"
```
## Run dashboards / commands !
