You are a very sharp cookie, I was impressed not even one minute into the video. Your tip of saving out the chart values for reference has accelerated my progress immensely, I don't know why but I had gravitated towards using --set to get things done, no more, tyvm :D
Thanks for watching. You can just add the lok datasource in your external Grafana provided you expose loki outside the cluster and that grafana can reach it. Cheers.
It's very helpful and to the point. Thanks. If possible, can you please make a small demo of "Simple scalable deployment of Grafana Loki ", which is latest and as loki-stack is mostly depreciated and could not find the official documentation as well.
Hi, thanks for watching. Why do you think loki-stack is deprecated? The chart is still maintained in grafana helm repository. I can certainly do a video on simple scalable deployment. I will try and record in the coming weeks. Cheers.
Hi Venkat.. It would great if you do for both in house cluster as well as cloud provided managed k8 cluster where one don't have access to the control plane.. Once again it's a great work Thanks again
@@sandeepmishal2376 Thanks for watching. I mostly cover the concept in a more generic way and let people explore further. I know people are not going to be running clusters on their laptop in the real world. But I won't be able to cover all the scenarios. Some might be interested in gke and other eks etc. But I will keep this in mind. Cheers.
Thanks Venkat.. I understood.. May be I could have been more specific to my comment and not confused you.. I was stating it for SSO using oidc topic where it can become a bit tricky as we will not have access to control plane . Sry for the confusion I love the generic way it self..
Hi Gordis, many thanks for watching. I haven't explored Grafana Tempo. I can add it to my list and I am going through my user requested videos list at the moment.
hi thanks for this guide,but how can i display all the namespaces of the cluster,because loki display only some namespaces to me in the grafana dashboard
Hello, I have setup the grafana/loki stack similar way you did. Now in grafana dashboards i am trying to create dashboard for individual pods and i am able to do it. But when i am restarting the pods, pods name gets changed. Now i am not getting any logs on dashboard. I am not sure if its the correct way of setting the dashboard i.e individual dashboards. or i just need to setup logs for namespaces only? would be grateful for your help
Great tutorial! Is there any way you could make an updated tutorial on this? Can you also touch upon their Grafana Cloud offering versus using the open source community version?
Great content, I could able to deploy Loki for our use case by referring this video. Thanks . I am also looking out the way to get the logs using Loki API for given pod
Hi Venkat, thank you for informatic video. I'm deploying it with grafana disabled, and how do I update the grafana enabled without deleting the configured?
@@justmeandopensource so i have deployed loki-stack with grafana disabled, but i want to change it to enable, is it possible without running "helmet uninstall" command?
@@pisckipratama9529 Ah okay. You should be able to change most of the stuff without uninstalling. For example, as shown in this video, if you checked out the values of the chart with "helm show values" to a local file and used that in helm install command with --values option, then you can edit that values file, enable grafana and run "helm upgrade --install --values ". I haven't tried it in this case but I know it worked for me in the past. However there are certain stuff in the values file that you can update on live deployment. You will have to helm uninstall it first and deploy again.
nice explanation, i have a question, if i need to configure logging on multiple kubernetes clusters can i use a single grafana instance for viewing the loki logs from different clusters?, appreciate your help
Hi Malcolm, thanks for watching. Yes that set up is entirely possible. You can have all logging stuff (like prometheus, grafana etc) on a separate cluster and configure ingress routes so that they can be connected from agents on other clusters.
Hi! Many thanks for that video! I have one question. I've installed loki and grafana. But I don't see how to expand log line and find out more details of log item.
Thanks for watching. Do you mean in Grafana that you can't see the full log item? I am not sure if loki truncates the log item. I would be surprised if it does that and there is no configuration to control that behaviour.
I’ve grafana loki stack running on my local docker desktop k8s , i’m integrating it with GitHub Oauth, what root url and callback url should i set, I’m getting mismatch redirect
Hello can you please make a video for setting up log retention period in loki stack. As i have tried to set the parameter according to documentation but doesn't retain the log according to set period.
Thank you for this amazing video. I have a question that I have a customize storage class of type gp2 along with PV and PVC , so shall I need to mention the PV and PVC in the Loki yaml file or the storage class name will be sufficient enough for the yaml.
I use Qutebrowser as my web browser on Arch Linux. This browser is python based and keyboard driven. You will find it extremely useful if you are a keyboard centric person and VIM user.
Thanks for the explanation, is there any way that grafana can send full information of logs in email as alert, we are getting alert but it is only giving count, if there any way to get full information of log in email?
Hi, can you do a video on how to add additional config to get logs for a custom application? What configs do we need to edit, is it the configmap for the created promtail service?
Thanks for the video. I followed the steps but 'Explore' page is empty for me even though loki data source is added. While checking the Javascript console, I see "Datasource named Prometheus was not found". Can you help?
This explanation was awesome! I saw your logs have also this prefixed metadata: `stderr` before the real log the JSON. How can you remove this so loki will recognize the json properties correctly!? If you use for example fluent bit instead of Promtail?
Thank you so much for the video, it was very helpful for me. I would also be very grateful if someone could tell me how to get the loki, promtoil configuration files after installation???
Hi, I am getting 502 bad gateway error, when I test data source in grafana, can you help me with this, my setup is with kubeadm on aws and it's single node, I am accessing grafana with nodeport.
Thank you for all your wonderful videos, I have a query regarding logs, can we use loki to monitor application specific logs, if not would you suggest any tools for application specific? Thank you.
Thanks for such a wonderful video. I'll really enjoyed the way explained. Can we do log rotation in LOKI? bcoz, in my production environment the EBS volume is getting filled with lots of logs. if i want to delete the logs which is 10 days older, how will i do that with loki?
Hi can anyone tell me how to get MySQL server query logs to Loki grafana dashboard, Mysql query logs are in pod container (opt/bitnami/MySQL/logs/query.log ) i want this logs which are in this pod container location to show displayed in Loki grafana dashboard can anyone here guide through this
Hi Chris, thanks for watching. I haven't tested the performance with large dataset. But according to them, it should perform better than Elasticsearch as it doesn't have the index overhead.
Hi Venkat,Can you Please give me yaml file for adding S3 bucket as storage .Have tried many ways but nothing is working .It would be great if you could help
Hi, thanks for watching. I am not sure why you would want to download the logs. Its because you wanted to retain the logs from various applications, you have deployed Loki and storing logs in there where you can query and visualize stuff. If you want to download logs, you will have to write a query and store the output in a file. Hope this helps.
I don't understand why you would skip setting up an ingress, in a real production env you wouldn't use port forwarding... All tutorials related to Loki fail to acknowledge the ingress.
Hi....I have loki promtail and grafana setup and want to see grafana usage per user with dashboard from grafana.log..I have referer label in logs which is having dashboard name along with https url but i only want to show dashboards accessed userwise..can you please help me for same?
