  2. Thank you Venkat . Your videos are pure gold .I am binge watching all your videos .One small suggestion , Please put a time marker in your video description where we can skip the part of bringing machines using vagrant. Amazing videos .

  3. Hi Venkat,

    I am facing issue with logstash can you plz help me to fix the issue. logstash service is up and running fine 5044 port is not listening.
    [2020-08-07T08:38:03,910][ERROR][org.logstash.Logstash ] java.lang.IllegalStateException: Logstash stopped processing because of an error: (LoadError) Could not load FFI Provider: (NotImplementedError) FFI not available: java.lang.UnsatisfiedLinkError: /tmp/jffi2780248845307238633.so: /tmp/jffi2780248845307238633.so: failed to map segment from shared object: Operation not permitted

  4. HI, the video is good but while setting up i was geting the below error i am not sure why this error is occurring by the way i have installed ELK 7.x version

    Error is

    ERROR pipeline/output.go:91 Failed to connect: dial tcp 192.168.1.165:5044: connect: no route to host

    i am not able to find 192.168.1.165:5044 as this is not server where i have installed the ELK.

  5. Hey man your videos are good. I'm install elk on centos. But in kibana UI when I'm doing check data. It's showing No data has been received from this module yet. I've followed your video only. Can you help please.
    Couldn't find any elastic search data

  6. Hi, in your logstash you have
    filter {
    if [type] == "syslog" {
    How does logstash know the input from filebeat is of type 'syslog'.
    I'd like to add my own logstash grok for a custom log format but how would I tell filebeat the type so that logstash applies the correct grok?

  7. if anyone getting failed to connect backoff(aysnc(tcp.
    My case is: 5044 port on server is listening and filebeat on client host prompting the error. It may be the firewall problem(?)
    I tried on the server host:
    firewall-cmd –zone=public –add-port=5044/tcp –permanet

    firewall-cmd –reload

    firewall-cmd –zone=public –list-all

    and then the problem is solved
    Hope it helps you.

  8. Hi Vankat, i m so thankful for all your efforts, I would really know if it is mandatory to install filebeat on client machine to export logs ? what about using rsyslog to export logs by customizing the config file to redirect logs to logstach remote machine. thanks in andvance

  9. Wow, so well done. I rarely have such luck researching topics like this on youtube. I've used your videos almost as much as a paid Udemy course while self-teaching myself ELK. Very concise, yet providing background information everywhere needed. Thank you

  10. Hi , i have installed ELK 6.8.8 on Centos 7, Could not able to send filebeat logs to the kibana dashboard, i have tried so many ways, can i get a demo session or for a online discussion to understand briefly
