Hi All, I've been trying to graph data obtains from a "SHOW STATUS" mysql query. When attempting to graph "Threads_connected" using Kibana is received the following error...
Oops! ClassCastException[org.elasticsearch.index.fielddata.plain.PagedBytesIndexFieldData cannot be cast to org.elasticsearch.index.fielddata.IndexNumericFieldData] I checked my mappings and the "Value" field has been added to elasticsearch as a string even though it only ever contains integer counts. I don;t really want to re-dump my data and change mappings so I've managed to fix the query using dynamic scripting like so... curl -XGET 'http://hostname:9200/_all/_search?pretty' -d '{ "facets": { "0": { "date_histogram": { "key_field": "@timestamp", "value": "doc['Value'].Intvalue", "interval": "5m" }, "global": true, "facet_filter": { "fquery": { "query": { "filtered": { "query": { "query_string": { "query": "source:mysql_status AND Variable_name:Threads_connected" } }, "filter": { "bool": { "must": [ { "range": { "@timestamp": { "from": 1411520355984, "to": 1411563555984 } } } ] } } } } } } } }, "size": 0 I have simply changed.. "value": "Value", to... "value": "doc['Value'].Intvalue", This query returns what I want but I am unable to get this into Kibana without it throwing some kind of error. So my question would be... how do I get my historgram to use data from the above query? Rhys -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
