Logstash stopping and restatŕting every 5 seconds and is using more than 600% of cpu

Logstash is using ore than 600% cpu and is starting and stopping again, actually it is working fine for the filters but still the cpu issue is critical and i am getting below error in the logstash logs -

it would be helpful if someone could help with this issue

Please share your configuration file. Do you have any configuration file in conf.d?

or check your configuration file in this way and show message:

/usr/share/logstash/bin/logstash --config.test_and_exit -f /etc/logstash/conf.d/

d

Did you make sure that Logsash has writing permissions for this directory?

Hi @d.silwon the conf.d is an emty folder now but i am using the below configuration file for my data parsing -


 input {
    beats {
        port => "5044"
    }
}
filter {
    
        dissect { mapping => { "message" => "%{timestamp1->} %{+timestamp1} %{+timestamp1} %{Theatre} %{Product} %{Severity} %{Body}" 

"Body" => "%{1} %{2} %{3} %{4} %{5} %{6} %{7}" } }
       

        kv { source => "Body" }
    }
output {
  elasticsearch {
    hosts => ["http://localhost:9200"]
    index => "%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"
  }
}


please check

The conf file looks good. Please check what is suggested by @Jenni
I have:
drwxr-x---. 2 logstash logstash 6 Jun 25 07:37 /usr/share/logstash/data/queue

Hi @Jenni i tried making it writable but same issues, can you please suggest how i can give permissions to logstash for this

Hi @d.silwon is this the command i can use to give permission?

Show rights:
ls -ld /usr/share/logstash/data/queue

The rights you can change in this way:
chmod 750 /usr/share/logstash/data/queue
chown logstash.logstash /usr/share/logstash/data/queue

but check it first.

it is showing the rigts as below -

drwxrwxr-x 2 root root 4096 Jun 16 14:18 /usr/share/logstash/data/queue

should i change them?

I think you should change rights for owner and group, should be logstash logstash

i changed it, now i am receiving the below error-

[2020-07-30T13:08:28,706][ERROR][org.logs

Did you change the permissions recursively or only for the top directory?

yes i changed for another directory as well after that it was asking for this directory /usr/share/logstash/data/dead_letter_queue
to be writable

But did you give it permissions for /usr/share/logstash/data/.lock?

no i gave permissions for /usr/share/logstash/data/queue

should i give permissions to /usr/share/logstash/data/.lock ?

and using these comaands ?-

chmod 750 /usr/share/logstash/data/.lock
chown logstash.logstash /usr/share/logstash/data/.lock

Please do it in this way:
cd /usr/share
chown -R logstash.logstash logstash

i tried this i think the issue is still there, i get the below messages
