I have a problem to showing string variable on grafana graph. I have a error like this: "Fielddata is disabled on text fields by default. Set fielddata=true on [....] in order to load fielddata in memory by uninverting the inverted index." Can you help me for this? I read many tutorials that say about " PUT my\_index ...". Im confused, how runs PUT command to enable fielddata. ---

Before you go and enable fielddata, I think there may be an better solution for you. By default, whenever you index a string field into Elasticsearch, [it will create a `.keyword` multi-field](https://www.elastic.co/blog/strings-are-dead-long-live-strings). Those multi-fields are of [type keyword](https://www.elastic.co/guide/en/elasticsearch/reference/current/keyword.html), and do not require enabling fielddata. If you haven't already provided a mapping yet, those `.keyword` multi-fields should be available to you. This multi-field can be accessed by simply adding `.keyword` to the field name. So, if you were trying to visualize a field called `foo`, try visualizing the field `foo.keyword` instead. ---

Oke thank you, I will try it.. Can I ask you about kibana or grafana? Do you have experience about alerting on kibana or grafana? I read many tutorial about alerting that say alerting of kibana need license? Is it true? Because it, now I want explore alerting of grafana. ---

Yeah, Alerting in the Elastic Stack is a paid feature - it requires a Gold subscription. I am not familiar with Grafana nor its alerting functionality. ---

Kibana is part of the Elastic Stack. What you pay for is support for the Elastic Stack, including Kibana. This page has all the details: [https://www.elastic.co/subscriptions](https://www.elastic.co/subscriptions) ---
