Hello, Kamlesh!
Thanks for trying out open census integration.
You can find self-explained example in Ignite sources [1].
To integrate with prometheus you have:
1. Enable `ignite-opencensus`.
2. Configure opencensus exporter in IgniteConfiguration:
```
OpenCensusMetricExporterSpi openCensusMetricExporterSpi = new
OpenCensusMetricExporterSpi();
// Metrics written to the collector each 1 second.
openCensusMetricExporterSpi.setPeriod(PERIOD);
cfg.setMetricExporterSpi(openCensusMetricExporterSpi);
```
3. Enable opencensus http server(after it you can view metrics values with the
http://HOST:PORT/ URL):
```
// Setting up prometheus stats collector.
PrometheusStatsCollector.createAndRegister();
// Setting up HTTP server that would serve http://localhost:8080
requests.
HTTPServer srv = new HTTPServer(HOST, PORT, true);
```
4. Grab metrics values in the prometheus:
prometheus.yml
```
scrape_configs:
- job_name: ‘ignite'
static_configs:
- targets: [‘localhost:8080’] # - same host and port as at step 3.
```
