Hi Team,
The elastic plugin suddenly started to show RED in Kibana dashboard.
Port 9200 is listening and process is also up but curl is giving some authentication errors.
Note - Nginx and X-PACK is not yet installed.
=============================================================================
[root@clm-pun-t2yior bin]# curl -XGET 'localhost:9200/?pretty'
{
"error" : {
"root_cause" : [
{
"type" : "security_exception",
"reason" : "missing authentication token for REST request [/?pretty]",
"header" : {
"WWW-Authenticate" : "Basic realm=\"security\" charset=\"UTF-8\""
}
}
],
"type" : "security_exception",
"reason" : "missing authentication token for REST request [/?pretty]",
"header" : {
"WWW-Authenticate" : "Basic realm=\"security\" charset=\"UTF-8\""
}
},
"status" : 401
}
