EFK (Elasticsearch+Fluentd-(td-agent)+Kibana): Kibana not showing correct logs

I have installed EFK on redhat linux system(version 7.6). Stable distribution of fluentd, that is td-agent is used instead of fluentd. Path of log file(/mnt/Log/Startup.log) is configured in td-agent.conf file. But on kibana dashboard it displays content from td-agent.log instead of log file(Startup.log).

td-agent.log:

```

Though above log shows that is it tailing the Startup.log. Still it shows content from td-agent.log on kibana dashboard and not the content from configured log file.

td-agent.conf :

```auto
<system>
log_level debug
</system>

<source>
@type tail
path /mnt/Log/Startup.log
pos_file /mnt/Log/Startup.log.pos
format multiline
format_firstline /\d{4}-\d{1,2}-\d{1,2}/
format1 /^(?<time>\d{4}-\d{1,2}-\d{1,2} \d{1,2}:\d{1,2}:\d{1,2}) \[(?<thread>.*)\] (?<level>[^\s]+)(?<message>.*)/
tag log
</source>

<match *.**>
   @type elasticsearch
    host localhost
    port 9200
    include_tag_key true
    tag_key @log_name
    logstash_format true
    flush_interval 10s
</match>

```

Version details:

Elasticsearch version 7.8.0  
Fluentd (td-agent) version 3.8.0  
Kibana version 7.8.0

I have installed all above tools using rpms:

elasticsearch-7.8.1-x86\_64.rpm  
td-agent-3.8.0-0.el7.x86\_64.rpm  
kibana-7.8.1-x86\_64.rpm

curl -X GET "localhost:9200/?pretty" gives:

{  
"name" : "ncnsidapp2",  
"cluster\_name" : "elasticsearch",  
"cluster\_uuid" : "MnfFXTyZT0ahp9u4eLSW2A",

"minimum\_index\_compatibility\_version" : "6.0.0-beta1"  
},  
"tagline" : "You Know, for Search"  
}

What could be the issue here? Please help.

Kibana will only ever be able to show you what Elasticsearch has received, so this sounds like an issue with td-agent rather than anything in the Elastic Stack.
