logstash output not showing up in kibana - elasticsearch

Question

I just started learning Elastic Search and trying to dump IIS logs to ES via logstash and see how it looks in Kibana.
Have set up all the 3 agents succuessfully and they run witout errors. But when I run logstash on my stored log files, the logs doesnt show up in Kibana.
(Am using ES5.0 which doesnt have the 'head' _plugin)
This is the output I see in logstash command.
Sending Logstash logs to C:/elasticsearch-5.0.0/logstash-5.0.0-rc1/logs which is now configured via log4j2.properties.

06:28:26.857 [Api Webserver] INFO logstash.agent - Successfully started Logstash API endpoint {:port=>9600}
But kibana doesnt show up any indexes. I am a newbie here and am not sure whats going on internally. Could you please help me understand what is wrong here.
Logstash Config file:
input {
file {
type => "iis-w3c"
path => "C:/Users/ras/Desktop/logs/logs/LogFiles/test/aug1/*.log"
}
}
filter {
grok {
match => ["message", "%{TIMESTAMP_ISO8601:log_timestamp} %{WORD:serviceName} %{WORD:serverName} %{IP:serverIP} %{WORD:method} %{URIPATH:uriStem} %{NOTSPACE:uriQuery} %{NUMBER:port} %{NOTSPACE:username} %{IPORHOST:clientIP} %{NOTSPACE:protocolVersion} %{NOTSPACE:userAgent} %{NOTSPACE:cookie} %{NOTSPACE:referer} %{NOTSPACE:requestHost} %{NUMBER:response} %{NUMBER:subresponse} %{NUMBER:win32response} %{NUMBER:bytesSent} %{NUMBER:bytesReceived} %{NUMBER:timetaken}"]
}
mutate {
## Convert some fields from strings to integers
#
convert => ["bytesSent", "integer"]
convert => ["bytesReceived", "integer"]
convert => ["timetaken", "integer"]
## Create a new field for the reverse DNS lookup below
#
add_field => { "clientHostname" => "%{clientIP}" }
## Finally remove the original log_timestamp field since the event will
# have the proper date on it
#
remove_field => [ "log_timestamp"]
}
}
output {
elasticsearch {
hosts => ["localhost:9200"]
index => "%{type}-%{+YYYY.MM}"
}
stdout { codec => rubydebug }
}

You can check the name of the index present in Elasticsearch with a plugin like kopf, or with the endpoint _cat/indices/, which you can access directly via a browser at [ip of ES]:9200/_cat/indices or via curl: curl [ip of ES]:9200/_cat/indices.
With Kibana you have to provide a pattern of the index names, which is by default logstash-*, as shown in your screenshot. This default is used in Kibana since, in the elasticsearch output plugin for logstash, the default index pattern is logstash-%{+YYYY.MM.dd} (cf doc), which will be use to name the index created with this plugin.
But in you case, the plugin is configured with index => "%{type}-%{+YYYY.MM}". So the index created will be of the iis-w3c-%{+YYYY.MM} format. So you'll have to replace logstash-* by iis-w3c-* in the field Index name or pattern
