hello
I've seen that a warning from the topic subject makes some troubles also for other users on this forum, but I believe this one is new here.
this warning shows for a field with epoch timestamp value. after some time I finally did ingest (via syslog) it with a set indexing template (otherwise it would be interpreted as a number).
while looking at the event in Kibana the field is "Unkonwn field" and the value (shows as a number) has this "no cached ...".
GET my_index/_mapping/field/timestamp_event
{
"my_index" : {
"mappings" : {
"timestamp_event" : {
"full_name" : "timestamp_event",
"mapping" : {
"timestamp_event" : {
"type" : "date",
"format" : "epoch_second"
I would like to see it as a human readable date not a strange number, but can't make it even though countless refreshing, index deletes, ingests and Kibana restarts.
Any idea what I did wrong? Seems I can't find it myself
regards!
