Exception while openig kibana filebeat dashboard

i and newbie to Elasticsearh and have configured elasticsearch + kibana on a windows server and it was perfectly working fine for last few days.

  1. Today when i tried to open kibana dashboard for winlogbeat and filebeat, it send an exception about something disk usage (although there was around 4GB available). So i created some more space in C drive and tried again. After a while winlogbeat loads successfully but on filebeat dashboard it is throwing exception.

"search_phase_execution_exception
all shards failed

please advise

  1. and also can i delete data from this folder as it is consuming lot of space:
    C:\ProgramData\Elastic\Elasticsearch\data\nodes\0\indices\or209yvfTsKkTPg5u_1QRw\0\index

Update= i have deleted the filebeat-* index pattern and tried to reinstall filebeat. when i run the PS cmd .\filebeat.exe setup -e. it shows an error..
ERROR instance/beat.go:951 Exiting: 1 error: fileset iis/var is configured but doesn't exist
Exiting: 1 error: fileset iis/var is configured but doesn't exist

can some body suggest how to solve this?

What do your Elasticsearch logs show?

Always use the API to delete data from Elasticsearch, never touch directories/folders directly on the filesystem as this can have adverse impacts.

thanks here is the elasticsearch log:

There's not much useful there unfortunately.

Is there anything in the Kibana logs? What is the current state of the cluster, you can check this this way?
