# System Monitor # System Monitor / System Observer
... or some better name. ... or some better name.
## Agent ## Client
Runs on your host and collects metrics. Metrics are aggregated and sent to central *collector*. Runs on your hosts and collects metrics. Metrics are aggregated and sent to the central *server*.
## Collector ## Server
Receives aggregated measurements from agents and saves metrics info InfluxDB. Receives aggregated measurements from clients and saves metrics into InfluxDB.
### Build & Test ## Plugins
Use the gradle build tool, which will download all required dependencies:
```shell
./gradlew clean build
```
### Local Testing
#### InfluxDB container
Start the InfluxDB container:
```shell
docker run --name=influxdb --rm -d -p 8086:8086 influxdb:1.8-alpine
```
To execute the Influx client from within the container:
```shell
docker exec -it influxdb influx
```
#### Grafana container
Start the Grafana container, linking it to the InfluxDB container:
```shell
docker run --name grafana --link influxdb:influxdb --rm -d -p 3000:3000 grafana/grafana:7.1.3
```
Setup Grafana to connect to the InfluxDB container by defining a new datasource on URL *http://influxdb:8086* named *sysmon*.
Loaded by the client and provides extensions for doing the actual metric monitoring.

# Server
Server component.
## Development
### Build & Test
Use the gradle build tool, which will download all required dependencies:
```shell
./gradlew clean build
```
### Local Testing
#### InfluxDB container
Start the InfluxDB container:
```shell
docker run --name=influxdb --rm -d -p 8086:8086 influxdb:1.8-alpine
```
To execute the Influx client from within the container:
```shell
docker exec -it influxdb influx
```
#### Grafana container
Start the Grafana container, linking it to the InfluxDB container:
```shell
docker run --name grafana --link influxdb:influxdb --rm -d -p 3000:3000 grafana/grafana:7.1.3
```
Setup Grafana to connect to the InfluxDB container by defining a new datasource on URL *http://influxdb:8086* named *sysmon*.
