titpetric has updated the docker build a few times over the last 24 hrs. I am suspecting you just hit a bad time trying to pull the image. See the build history here: https://hub.docker.com/r/titpetric/netdata/builds/ Could you try again please?

According to netdata this should fix it: Map /var/run/docker.sock to /var/run/docker.sock This comes with some risks and it did not work for me. See here: https://github.com/titpetric/netdata#monitoring-docker-container-metrics Please let me know if this works for you. I only have a 6.1 version to test on, maybe it works on 6.2? @dertbv, did that work for you? I don't even see any dockers in the stats. Might need to upgrade to 6.2beta....

netdata does not need a config file to run. One of the principles of the developer is that it works things out on the fly. But if you want to do stuff yourself: - go to http://tower:19999/netdata.conf : This will show your current config file (default is everything commented out) - Copy paste / save it into your new config directory (/mnt/cache/appdata/netdata/netdata.conf) - make the changes you want - Restart the container worked for me

The config directory is not exposed by the container. You might be able to map /etc/netdata to /mnt/cache/appdata/netdata/ to make this work. I am at work right now and can't try. Just hit edit on the container configuration, change nothing and hit ok. It will download all the changes if titpetric's docker was updated.

Hi Squid, It was very late here in Sydney by the time I had this finished. Could you please add this template to CA? Is there anything else i need to watch out for? Thanks

Lots has changed in the last few years, here a new start. Overview: Template for the official netdata docker Real-time performance monitoring, done right! Application:netdata https://github.com/netdata/netdata/ & https://docs.netdata.cloud/ Docker Hub: https://hub.docker.com/r/netdata/netdata GitHub: https://github.com/netdata/netdata/tree/master/packaging/docker Repository: https://github.com/Data-Monkey/docker-templates Template: https://raw.githubusercontent.com/Data-Monkey/docker-templates/master/Data-Monkey/netdata.xml Credit: to titpetric who created the original docker and spants who's initial docker command kicked of the build for this template. and to lots of the forum users that keep answering questions here when I am busy otherwise. All of the issues listed below are now fixed in the new docker or the new version of unRAID. Hope this makes it all a bit easier now. Adding your own config files: The official docker does not support the override folder that the previous version had. So if we need config files, we need to mount them one-by-one. To start with the master config file, get the template from your netdata docker: wget [your_netdata_ip]:19999/netdata.conf then edit that file and mount it into the docker: -v '/mnt/cache/appdata/netdata/netdata.conf':'/etc/netdata/netdata.conf':'rw' 'ro' might be good enough. Rinse & repeat for all other files that you need. https://github.com/netdata/netdata/issues/5782#issuecomment-479572521 ================== Original First Post ================== Overview: Template for the netdata docker maintained by titpetric Real-time performance monitoring, done right! Application:netdata https://github.com/firehol/netdata/wiki Docker Hub: https://hub.docker.com/r/titpetric/netdata/ GitHub: https://github.com/titpetric/netdata Repository: https://github.com/Data-Monkey/docker-templates Template: https://raw.githubusercontent.com/Data-Monkey/docker-templates/master/Data-Monkey/netdata.xml Credit: to titpetric who created the docker and spants who's initial docker command kicked of the build for this template. HOW TO install this container: This template is now available in CA, just install the Community Applications plugin , search for netdata and add it. show container details in the graphs: Netdata does not support docker details prior to 6.2 due to the different docker api. If you are using unRAID6.2 the docker containers show up, but only by ID, not names. To make the names work /var/run/docker.sock needs to be mapped as well and the user running netdata needs rw access on the host. Not exactly a good thing to do, but it works. So if you want to go down that path do this at your own risk! AT YOUR OWN RISK!! -v "/var/run/docker.sock":"/var/run/docker.sock":rw and on the CLI as root run chmod 666 /var/run/docker.sock (this will need to be repeated at reboot) a better solution would be to run the docker under a specific user that is in the docker group. Still working on this! change the configuration: netdata by default does not need a config file. It works things out on the fly. If you want to have more control - go to <your host>:19999/netdata.conf - save the config file that shows up under (default) /mnt/cache/appdata/netdata/netdata.conf ( 2018/05 this now maps to /etc/netdata/override in the container!) - make the changes - restart container keep the logfile size under control: if you are on 6.2.x docker can do that for you. The extra parameters: --log-opt max-size=50m --log-opt max-file=1 restrict the log to 1 file of 50MB if you are on 6.1 the above won't work and you have to delete the logs manually every now and then. You can check the log size with this: du -ah /var/lib/docker/containers/ | grep "log$" | grep `docker ps -a | grep titpetric/netdata | cut -d" " -f1` Reverse Proxy: I have a ngnix example working here: https://lime-technology.com/forum/index.php?topic=49534.msg488617#msg488617 still to do: - run docker as special user in the docker group - reverse proxy config - resolve docker names in netdata - https://lime-technology.com/forum/index.php?topic=49534.msg475480#msg475480 - expose config dir to unRaid - https://lime-technology.com/forum/index.php?topic=49534.msg475483#msg475483 - fix log file growth - https://lime-technology.com/forum/index.php?topic=49534.msg475245#msg475245

ok. just not sure if there are very valid reasons to be doing this Yes, not sure either why I have it like this. Might be a left over from testing or an old template? I changed it now. But a nice pick-up by your plugin.

My DuckDNS is in HOST mode and the error still there. Maybe the template is BRIDGE but it is running in HOST, could be another check .... Nginx-letsencrypt I mapped port 80 to something and the error goes away as you said. But I don't want to map port 80. Might raise this in aptalca's support thread. Thanks for your quick answer and all the good work.

Hi, I got this error today for a few of my dockers: Docker Application DuckDNS, Container Port not found or changed on installed application With this description: When changing ports on a docker container, you should only ever modify the HOST port, as the application in question will expect the container port to remain the same as what the template author dictated. Fix this here I don't think I ever changed the ports and all works fine. Might be a red herring? The DuckDNS container runs in host mode and does not have any ports mapped. For Nginx-letsencrypt it complained that port 80 is missing. But I don't really need one, right? Docker Application Nginx-letsencrypt, Container Port 80 not found or changed on installed application EDIT: running unRAID 6.1.8

Thanks! It will still be a headless server, so not GPU required for the VMs. I will give it a spin. Looks like I need a bigger cache disk soon ...

I finally got around to upgrade my BIOS to the 2003 version and tried switching on the virtualisation. I found the VT-x setting but there is no VT-d setting. Could be because my CPU does not support it!! i3-4130 does have VT-x but not VT-d Can I still do virtualisation in unRAID? What would be the restriction? Thanks

This is great news! I am the OP and always thought I did not have virtualisation capabilities here. Now it is time to drag the screen and keyboard back to the tower and change some settings. I am still running the bios from Jan 2014 would you suggest I upgrade while I am at it? Thanks

Thanks gfjardim! I reloaded both dockers, added the parameter to the desktop container and all is good again :-) Thanks for all your contributions here

Just a note to your /mnt/user0 question, this is not created by the docker but by unRaid itself. /mnt/user shows all your shares including the files still in the cache share /mnt/user0 only has the files/folders that are on the array.

There is also a emoncms connector..., I saw it is rather simple to add the nodes, but would they "survive" a docker rebuild? On a different question, once I started writing to the file the disk obviously does not spin down anymore. Do you just write to your cache drive? Thanks

Thanks, emoncms looks interesting. Since you are asking, some MySQL/MariaDB nodes would be great.

This is great. It took me about 15min to install and connect to a "hidden" API on Efergy to read my real time energy consumption and write it to a file. Just for fun I attached a web-service to dump the file back to a website. I followed the video on the first post and this little blog: http://blog.krisdaniels.be/efergy-engage-api/ Next challenge to store the data in a MariaDB.

Thanks, I followed the upgrade instructions on the wiki. I had a second key and USB so that made it a bit easier (less risky) and everything went smoothly. As a starting point I stuck to the PhAzE plugins and as they work in 5 and 6 it was super easy to be back up and running in no time. Will certainly look at Dockers next and then VMs :-)

After having this running now for over a year I think it is time I try unRAID v6. So I got myself a second USB and a second KEY, now the question is, is the hardware actually good enough for unRAID v6? Currently it only runs a few PhAzE plugins (Plex, Trasnmission, Filebot) These should just run again in V6. But if I want to take advantage of Dockers or VMs, will my hardware support that? And if not, what would I have to invest in? Current Setup: Case: Lian Li PC-Q25 Black Hot Swap Mini Tower Case Board: ASUS H87I-PLUS CPU: Intel Core i3 4130 RAM: 8GB G.Skill Ripjaws X F3-12800CL8D-8GBXM (2x4GB) DDR3 PSU: Silverstone ST45SF 450W SFX Disk: 2x 4TB WD Red (1 data, 1 parity) Cache: 120 GB Samsung SSD 840EVO USB: Cruzer Fit (8GB) Thanks

Hexen, I had just rebooted my tower so the syslog is only 2 days old, but there are no more [mse] errors in there. I unbundled the cables as suggested, but same as you mentioned, even when these errors were around I never had any issues, so I stopped looking. Your question prompted me to check, but nothing (in 2 days of not much use)

Hi, so my build has been running for a while now. No issues at all. I added a 4TB parity and a SSD for Cache. Use it mostly as a backup of my data/photos and as PLEX Media server. Now I would like to hide some of my traffic as descrbed in this post: http://lime-technology.com/forum/index.php?topic=32090.0 But I don't have the second network port or the required (Tomato compatible router). Has anybody good and affordable recommendations? Thanks Roland

oxidized, I based it on garycase's post here: http://lime-technology.com/forum/index.php?topic=29670.msg266348#msg266348 and his assurance that it would have no impact here: http://lime-technology.com/forum/index.php?topic=29670.msg274292#msg274292 I like that the cables come out in a better position and I can tuck away the "leftovers" on top of the PSU. But if you guys think it might not be a good position I can change it around. Are there any indicators I could check to see if there is any impact? Roland

Yes, I used the same CPU to flash. It is the only one I have. Guess I got lucky. I still get the [mse] errors occasionally. How do I investigate these? Ok, I will unbundle the SATA cables. Thanks
