First off all thanks for the excellent vidéo it has helped me in my project.
Thank you. It's very helpful.
a little hint with today docker 23 update :) docker-compose up -d become docker compose up -d - wthout dash in the middle :)
Hello, great video!
From what I understand Redis is not actual dependency. It is used on the prometheus guide just as "reference container" for examples
Thank you for your comment! Good point!
nice!!! Very handy!!!
Thank you Andrea!
Great tutorial! Do you have some guide to read better logs of all containers?
Currently I'm using Dozzle, but I saw some solutions like ELK (Elastic Search, Logstash and Kibana) , any chance to you bring some tutorial to implement in docker-compose?
Excellent tutorial. Thanks for this! I'm just getting started with Prometheus and Grafana. Have two questions: 1) Have you seen any dashboards that aggregate Linux, Windows and Docker monitoring into a single (perhaps very simplified) view? 2) Do you have recommendations for alerting? Meaning, if a docker container is reporting as unhealthy, or a specific Linux OS metric is reporting above/below a set threshold, an alert is sent via email/sms to admins...
Heavy on the configuration. You'd think that a monitoring agent would be able to push metrics out instead of listening. So now you have to install the agent (Windows Exporter), configure the Windows firewall, and setup Prometheus to pull metrics.
Anyway, a great video even if the configuration is cumbersome.
so easy turotial, Good job
thanks bro
Janu thanks for the comment! So glad it was helpful.
@@VirtualizationHowto you are welcome bro
i love this, thanks
Thank you too!
Thank you for share. Greetings
Thank you for your comment! Take care.
Great video!
Does anyone knows how much CPU and memory this monitoring stack uses?
Thanks! Looks more pretty than Zabbix.
Vasilly, I definitely prefer PRTG for its capabilities, look, and feel...
i beg you pardon in case you already explained this in the video (i'm still at the beginning), or you can maybe make a video on this in the future, please: having BOTH metrics AND logs combined in a grafana dashboard, so to have a complete monitoring solutions, scrolling both "targets" in sync/parallel, to have a full view on what, how and when something happened... thanks!
ok, saw full video, probably what i asked is related more to kubernetes and less to docker, really... but, in case, a video covering this "extended" setup would be much appreciated :D
I have a question what would the configuration of the exporters and the Prometheus server be like if the servers were AT the company's office and the Prometheus server was AT home.
Basically a remote monitoring. Thanks
Not sure if this has been asked already. Can you add how also how install the snmp exporter. Thanks
How do you decided ip address for targets? There is docker ip address too!
Hello! Perfect tutorial. The only problem for me, where do you get the IP for grafana? Should I go by localhost or I need to find grafana's IP?
ifconfig
how to add target if I have 5 VM running on premise server? Just newbie
Hello, i am unable to hit node exporter and cadvisor metrics endpoints via prometheus. It gives me context deadline exceeded error. However when i try to curl it works like charm. Can you please help me with this?
How do I add other servers to prometheus? Like 2 linode and a digital ocean server? I'm running prometheus locally, so would i need to create cloudflare tunnels???? Also can you make a video on running grafana and prometheus on trunas?
nice, But how to monitor VMware ESXI and True Nas Core Storage?
@daiben2004 Thank you for your comment! Sign up on the forums and I can give more personalized help here: www.virtualizationhowto.com/community. Thank you again.
It doesnt seem like grafana can see the nodes i have from cAdvsior. My Docker container dashboard has no data. What steps can I take to troubleshoot this?
i have this problem too. Did you find any answers for fix this issue?
Can anybody help us?
need some assistance:
Prometheus is up and working, I have node exporters loaded on few server. Prometheus is able to identify them and scrape them.
Installed Grafana and connected to Prometheus but Grafana is not able to show any data in dashboard
any recommendations?
Hello and thanks for the comment! Does grafana see the prometheus data source when you add it in settings?
Can we create a metrics to monitor service status like ntpd, chronyd, auditd in Prometheus
@shamshershaikh17 thank you for the comment! Sign up for the forums here: www.virtualizationhowto.com/community and let's discuss it in more detail there.
mkdir: can't create directory '/var/lib/grafana/plugins': Permission denied
Nope, not interested in a docker based solution... moving on.
Aww. Come on. Try it.
I am having an issue with prometheus. When I try docker-compose up -d there is one error that occurs.
Cannot start service prometheus: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error mounting "/root/monitorsvr/prometheus/prometheus.yml" to rootfs at "/etc/prometheus/prometheus.yml": mount /root/monitorsvr/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml (via /proc/self/fd/6), flags: 0x5000: not a directory: unknown: Are you trying to mount a directory onto a file (or vice-versa)?
How to solve this?
erefem make sure you created a directory and not a file in your Linux environment. Also, check out permissions. Let me know if this helps.
@@VirtualizationHowto I follow every step carefully but have had no success. I also add user to docker group. Is there something I am missing here?
@@rainbowforest09 1. Switch your user to root and run everything from there.
2. Check the user id (id -u) then change it to match accordingly in the docker-compose.yml file as in the video. Then proceed with the steps as he has done. It will work.
I have exactly the same issue as erefem. lsb_release -a
