I just saw this video it's very useful.It work perfectly fine for me. There was one question you ask why second time you didn't have to start service. I think this because of Linux default function that you have to restart the service if you make any changes in config file. Second time I guess you made changes in yml file not in config.

[@justmeandopensource]

Hi Apurva, thanks for watching. You don't have to restart service each time change the config as the service will reload automatically on detecting changes in the files.

[@jamallmahmoudi9481]

Hi Venkat, cool & perfect I have a question How should I define a heartbeat to monitor all pods in a Kubernetes cluster? Do I only need to install and configure Heartbeat on the worker node, or do I need to install and configure it on each pod in the cluster? I appreciate any advice 🙏🙏🙏

[@jorgelarrondo3666]

Any idea why my heartbeat is not reading my .yml file in monitors.d? Path to it in the heartbeat.yml file is correct

[@justmeandopensource]

Hi Jorge, thanks for watching. Did you update yml files in monitors.d after starting the hearbeat service? Did you try restarting the heartbeat service after editing the yamls in monitors.d? I remember there is an option that you might need to enable so that the changes are picked up dynamically instead of restarting heartbeat service.

[@nikhiljain5815]

Thanks for great demonstrations on Heartbeat & ElastAlert too. Just quick clarification - Heartbeat is fully free (open source) just like ElastAlert? thanks again.

[@vanmemet]

Excellent videos. Thank you. In 23:15 is that a goat sound or a child sound in background? :-)

[@justmeandopensource]

Hi Ibrahim, thanks for watching this video. Its probably my child and not goat :)

[@ananyaananthrao7417]

Thanks for the great video! Any idea on how many packets are sent by an ICMP monitor whenever it sends an ICMP Echo Request? Thanks again!

[@abhilashpatil2488]

Hi I am facing an issue here , I have configured kibana,logstash Ani Elastic search in docker container and manually installed heartbeat , but after starting heartbeat I can see the data inside discover tab but not in uptime I am getting error for no monitors found

[@justmeandopensource]

Hi Abhilash, thanks for watching. So your heartbeat installation is working fine and that it can connect to the elasticsearch without any issues? How is your set up different to the one in this video? I would need more details to investigate this.

[@jovanivanovski4678]

Hi, great video, I want to ask is it available on kibana some statistics for example how much time server was up or down(on daily base or long period week or months)?

[@justmeandopensource]

HI Jovan, thanks for watching. Kibana is just a visualization tool. You can use metricbeat to collect stats from the clients and store it in elasticsearch which can then be viewed using Kibana.

[@dineshreddy3003]

my elasticsearch and kibana is running in diff node but in same namespace when im trying to setup heartbeat im getting following error, can you help me with this, thanks in advance. Exiting: fail to create the Kibana loader: Error creating Kibana client: Error creating Kibana client: fail to get the Kibana version: HTTP GET request to /api/status fails: fail to execute the HTTP GET request: Get kibana.---.com:5601/api/status: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers).

This video is amazing, learnt alot. Can you plz tell me how we can configure praeco notification alerts for heartbeat in ELK ?

[@thyagtubes]

Please zoom in a bit for your next videos, helps a bit while watching on mobile

[@justmeandopensource]

Hi Thyag, thanks for watching and the feedback. I will look into that. I am not using any fancy recording software that can zoom in the place under the cursor or something like that. But I will investigate the options. Thanks.

Hi Venkat sir, I'm having doubt on how to fetch puppet open-source or enterprise database into my elasticsearch..?

How to integrate k8 cluster environment o elk for monitoring?

[@justmeandopensource]

Hi Praveen, thanks for watching this video. I have done a video on using EFK stack in a Kubernetes cluster. You can check that in the below link. kzbin.info/www/bejne/bp-6mWR9gclqpLs The setup involves running Fluentbit/Fluentd as deaemon set on each worker node. The fluentbit/fluentd then collects logs from the host machines docker environment and forwards it to the elasticsearch container that is running again in the same k8s cluster. If you have a separate elasticsearch/kibana setup running outside of the kubernetes cluster, You can just deploy fluentbit using helm and configure the elasticsearch url to point to your elasticsearch instance. Thanks.

[@Praveen-xx7iy]

@@justmeandopensourcethanks for your response, but in my environment we are using logstash..any video with elk?

[@justmeandopensource]

@@Praveen-xx7iy I did a video on ELK last year that has nothing to do with Kubernetes but will give you a general idea. kzbin.info/www/bejne/eZfFkqGfpJh_l9E Thanks.

How to remote access kibana dashboard ?

[@justmeandopensource]

Hi Jagadeesh, thanks for watching. In this video, I ran Kibana as docker container exposing port 5601 which can be access from the localhost. If you want to access it from other machines in the network, you can bind to 0.0.0.0:560. Or you can set up Apache or Nginx reverse proxy. Cheers.

[@jagadeeshramaiah1593]

Thank you for your replay . We have another concern here : In same network segment we are able to access kibana in remote machine, but if ip segment getting change we cannot access kibana Web UI, but only we can Ping and ssh that machine, We need your help on this.

[@justmeandopensource]

@@jagadeeshramaiah1593 I don't understand this. Tell me more about how your set up is looking now and how you want to change it.

[@umartariq3579]

Very well explained, Thanks for making such knowledgeable stuff!! Cheers . Want to ask something , can we also create alerts for example if any of our heartbeat checks failed so we get notified, so can follow your ElastAlert video ?

[@justmeandopensource]

Hi Umar, thanks for watching this video. Yes you can use Elastalert to get notified by any means (one of its alerters eg: email, slack notification, Jira notification...). Any data that gets to Elasticsearch can be queried using Elastalert to create rules for alerting. In the alert rule, you just say which index you want to query and for what patterns you need to query. A sample rule definition would be something like below. index: heartbeat-* type: frequency timeframe: minutes: 1 num_events: 1 filter: - term: monitor.status: "down" alert: - "email" email: - "[e-mail]" Thanks

[@umartariq3579]

Thanks for the explanation, appreciate your efforts. Keep up the good work!! Cheers

I was hoping for the heartbeat to be on docker aswell :)

Hi, thanks for watching. Heartbeat on docker is also possible. May be I will do it in future video. Cheers.
