I have this log file:
`2020-08-05 09:11:19 INFO-flask.model-{"version": "1.2.1", "time": 0.651745080947876, "output": {...}}`
This is my logstash filter setting
`grok{
match => {
"message" => "%{TIMESTAMP_ISO8601:timestamp} %{LOGLEVEL:log.level}-%{DATA:model}-%{GREEDYDATA:log.message}"}
}
date {
timezone => "UTC"
match => ["timestamp" , "ISO8601", "yyyy-MM-dd HH:mm:ss"]
target => "@timestamp"
remove_field => [ "timestamp" ]
}
json{
source => "log.message"
target => "log.message"
}
mutate {
add_field => {
"execution.time" => "%{[log.message][time]}"
}
}
}`
I want to extract the "time" value from the message. But I receive this error:
`[2020-08-05T09:11:32,688][WARN ][logstash.outputs.elasticsearch][main][81ad4d5f6359b99ec4e52c93e518567c1fe91de303faf6fa1a4d905a73d3c334] Could not index event to Elasticsearch. {:status=>400, :action=>["index", {:_id=>nil, :_index=>"index-2020.08.05", :routing=>nil, :_type=>"_doc"}, #<LogStash::Event:0xbe6a80>], :response=>{"index"=>{"_index"=>"index-2020.08.05", "_type"=>"_doc", "_id"=>"ywPjvXMByEqBCvLy1871", "status"=>400, "error"=>{"type"=>"illegal_argument_exception", "reason"=>"mapper [log.message.input.values] of different type, current_type [long], merged_type [text]"}}}}`
