Bitcoin e le "crypto-valute" in generale continuano a riscuotere molto interesse per gli addetti ai lavori ma non solo.

Oggi vedremo come poter monitorare le performance di queste valute con Elastic Stack e [CoinMarketCap API](https://coinmarketcap.com/)

Vogliamo anche far uso di una nuova fantastica feature di Logstash che ci consente di modificare le nostre pipelines direttamente da Kibana UI senza dover riavviare Logstash dopo ogni modifica 🕶🚀

Per abilitare remote management e dichiarare una pipeline, aggiungiamo la configurazione seguente in logstash.yml:

```
#remote management
xpack.management.enabled: true
xpack.management.elasticsearch.url: "https://es-node:9200"

#autenticazione
xpack.management.elasticsearch.username: logstash_admin
xpack.management.elasticsearch.password: password
xpack.management.logstash.poll_interval: 5s 
xpack.management.elasticsearch.ssl.ca: "/path/to/ca/ca.crt"
xpack.management.elasticsearch.ssl.keystore.path: "/path/to/node/cert.p12"
xpack.management.elasticsearch.ssl.keystore.password: "secretpassword"

#la nostra pipeline
xpack.management.pipeline.id: ["coins"]

```

Usiamo Logstash Input [http\_poller](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-http_poller.html) per accedere ai dati offerti da CoinMarketCap per ottenere i dati sulle crypto valute:

```
input {
        http_poller {
            urls => {
                btc => "https://api.coinmarketcap.com/v1/ticker/bitcoin/"
                ltc => "https://api.coinmarketcap.com/v1/ticker/litecoin/"
                eth => "https://api.coinmarketcap.com/v1/ticker/ethereum/"

                globaldata => "https://api.coinmarketcap.com/v1/global/"
            }
        request_timeout => 60
        schedule => { cron => "*/1 * * * * UTC"}
        codec => "json"
        }
}

filter {
         
}

output {
        stdout{codec=>rubydebug}
        elasticsearch{
                hosts => "https://es-node:9200"
                index => "coin-metrics-%{+YYYY.MM.dd}"
                user => "logstash_writer"
                password => "password"
                ssl => true
                cacert => "/path/to/ca.crt"    
        }
}

```

In Elasticsearch utilizziamo un dynamic template  
per assicurarci che i dati vengano indicizzati con i tipi di dato adatti per poter eseguire tutte le [aggregations](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations.html) piú interessanti:

```
PUT _template/coin
{
  "order": 0,
  "index_patterns": [
"coin*"
  ],
  "settings": {
"index": {
  "number_of_shards": "1"
}
  },
  "mappings": {
"doc": {
  "dynamic_templates": [
    {
      "usd_as_double": {
        "match_mapping_type": "string",
        "match": "*_usd",
        "mapping": {
          "type": "double"
        }
      }
    },
    {
      "eur_as_double": {
        "match_mapping_type": "string",
        "match": "*_eur",
        "mapping": {
          "type": "double"
        }
      }
    },
    {
      "pct_as_double": {
        "match_mapping_type": "string",
        "match": "percent_change_*",
        "mapping": {
          "type": "double"
        }
      }
    },
    {
      "price_as_double": {
        "match_mapping_type": "string",
        "match": "price_*",
        "mapping": {
          "type": "double"
        }
      }
    },
    {
      "rank_as_long": {
        "match_mapping_type": "string",
        "match": "rank",
        "mapping": {
          "type": "long"
        }
      }
    },
    {
      "supply_as_long": {
        "match_mapping_type": "string",
        "match": "*_supply",
        "mapping": {
          "type": "long"
        }
      }
    }
  ]
}
  }
}

```

In pochi minuti abbiamo creato una dashboard con diverse visualizzazioni:

i prossimi passi potrebbero consistere nello sfruttare questi dati tramite [Timelion](https://www.elastic.co/blog/timelion-tutorial-from-zero-to-hero) , configurare qualche alert per notificarci via [slack](https://www.elastic.co/guide/en/watcher/current/actions.html#actions-slack) o eseguire un'altra azione...
