# Telemetry

|
|
## Enabling Kava Metric Telemetry
|
|
|
|
To enable the kava app to emit telemetry during operation, update the relevant config values to enable metrics:
|
|
|
|
`config.toml`
|
|
|
|
```toml
|
|
[instrumentation]
|
|
|
|
# When true, Prometheus metrics are served under /metrics on
|
|
# PrometheusListenAddr.
|
|
# Check out the documentation for the list of available metrics.
|
|
prometheus = true
|
|
|
|
# Address to listen for Prometheus collector(s) connections
|
|
prometheus_listen_addr = ":8888"
|
|
```
|
|
|
|
`app.toml`
|
|
|
|
```toml
|
|
[telemetry]
|
|
|
|
# Prefixed with keys to separate services.
|
|
service-name = ""
|
|
|
|
# Enabled enables the application telemetry functionality. When enabled,
|
|
# an in-memory sink is also enabled by default. Operators may also enabled
|
|
# other sinks such as Prometheus.
|
|
enabled = true
|
|
```
|
|
|
|
Then restart the service with the updated settings
|
|
|
|
## Running local prometheus collector and grafana services
|
|
|
|
To collect app metrics and visualize them locally, you can run the prometheus collector and grafana services with docker compose from the repo root directory (after updating `config.toml` and `app.toml` as detailed above)
|
|
|
|
```bash
|
|
docker compose -f prometheus.docker-compose.yml up
|
|
```
|
|
|
|
Navigate to localhost:3000 to view the grafana unix
|
|
|
|
Login with `admin` as the username and `admin` as the password
|
|
|
|
Hook up grafana to the local prometheus collector by navigating to `http://localhost:3000/connections/datasources/new`, selecting prometheus, entering `http://prometheus:9090` for the url, and clicking `Save & test` at the bottom of the screen
|
|
|
|
See [grafana docs](https://grafana.com/docs/grafana/latest/dashboards/) for information on how to construct queries and build dashboards

|
### Collecting from local host
|
|
|
|
Update [prometheus config](../prometheus.yml) to collect metrics from your local source, where the port matches the value set for `config.toml/instrumentation.prometheus_listen_addr`
|
|
|
|
```yaml
|
|
metrics_path: /
|
|
static_configs:
|
|
- targets:
|
|
- docker-host:8888
|
|
```
|
|
|
|
### Collecting from remote host
|
|
|
|
Update the kava config on the host and restart using the instructions from `Enabling Kava Metric Emission`
|
|
|
|
Install [ngrok](https://ngrok.com/download) on the remote host
|
|
|
|
Run ngrok on the remote host to forward the prometheus metric port
|
|
|
|
```bash
|
|
ngrok http 8888
|
|
```
|
|
|
|
```yaml
|
|
scrape_configs:
|
|
- job_name: proxy
|
|
scheme: https
|
|
metrics_path: /
|
|
static_configs:
|
|
- targets:
|
|
- 4efb-18-207-102-158.ngrok-free.app
|
|
```
