Nagios Support Forum

Hello Team,
We are unable to login the nagios logserver. Login page loads but it fails to login. Disk storage was full so we deleted an index to create some space and restarted logstash/elasticsearch/httpd services and even rebooted the server but still no luck. Please find the elasticsearch and logstash logs for your reference,
Below are few outputs for your reference,

-bash-4.2r$ curl -XGET "http://localhost:9200/_cluster/allocati ... ain?pretty"
