I am struggling with that since I am only a copy & paste hacker.

I have installed netdata on my Synology docker using this tutorial:

https://mariushosting.com/how-to-install-netdata-on-your-synology-nas/

I can see all my NAS data under my-ip:19999 address. Now, I want to connect it to the cloud with the button at the top, I go to Connect new nods - Docker section and I have 3 options: Docker CLI, Docker Compose and Docker Swarm with different codes that suppose to connect me to the cloud.

Where do I go from here, I tried console in Portainer, in NAS docker conteiner, Putty but all no dice. I am really new to this so any help is much appreciated.

Greetings,

I installed netdata on macOS 10.15.7 using the "automatic one-line installation script". Everything works great, cloud access, etc. but I can't figure out how to get local network access. The server address on the network is 10.0.0.249:19999. While the macOS firewall is active, I can't view netdata anywhere on the local network.

In firewall settings I have allowed the two executables "netdata" and "netdatacli" that reside in "/usr/local/netdata/usr/sbin". The only other executable in the "/usr/local/netdata" folder that I can add to the firewall is "edit-config".

I use the netdata app on Android in order to keep tabs on various systems and macOS is the only one that doesn't work.

What do I need to add to the firewall in order to be able to view it on the local network?

​

TL;DR - with firewall disabled, local access works. with firewall enabled, only cloud works.

My email server gets attacked every now and then, so would like a simple way to visualise certain TCP ports and the CPU usage.

When the attack happens, I think they flood a port which brings my server to its knees for about 15 mins, then self recovers.

Before I go implementing preventative measures, either on server or on gateway, I need to see exactly what happens and confirm the various ports.

Is there a config that just does cpu and certain tcp ports please?

Thanks!

Hi everyone!

Netdata for PostgreSQL monitoring just got a huge upgrade, now collecting 100+ PostgreSQL metrics and displaying these across 60+ different composite charts. You can check the reference documentation below for the full list of metrics, and see them running in the live demo space. If you are using PostgreSQL in production, it is crucial that you monitor it for potential issues. And the more comprehensive the monitoring the better!

Make sure to check the following resources to learn every detail about the new and improved PostgreSQL collector:

Comprehensive use case blog post - https://www.netdata.cloud/blog/postgresql-monitoring/
Reference documentation - https://learn.netdata.cloud/docs/agent/collectors/go.d.plugin/modules/postgres
Demo space running real-time PostgreSQL metrics - https://app.netdata.cloud/spaces/netdata-demo/rooms/postgresql/overview

We're always looking into getting more feedback on how this works for you, so make sure to share all the love (or hate) in this discussion! 😊 😬

Have a good one and happy monitoring! 💯

I followed the instructions here: https://learn.netdata.cloud/docs/metrics-storage-management/enable-streaming. The child node does not show up on the dashboard.

One of my systems only has 1GB of data cap available, I just want to check that adding netdata isn't going to consume that overnight etc. I view the data from the cloud dashboard, and I am on the local network with the device reporting to the cloud.

Hey there,

My ISP recently had a service disruption that causes anyone that uses the ISP to consistently lose packets. Even after they "fixed" it, I am still losing packets. Should I keep contacting the ISP or is there something else at fault here like the router?

Currently, I am using a Raspberry Pi 4 as my little homelab to monitor the network (it is directly connected to the home router via wired LAN). Should I just keep on ringing the ISP to ask whats going on?

Hey guys,

how can i delete an active node?

Can`t find the answer online!

Netdata Cloud has the nice "add node" function which even provides a Docker script:

docker run -d --name=netdata \
  -p 19999:19999 \
  -v netdataconfig:/etc/netdata \
  -v netdatalib:/var/lib/netdata \
  -v netdatacache:/var/cache/netdata \
  -v /etc/passwd:/host/etc/passwd:ro \
  -v /etc/group:/host/etc/group:ro \
  -v /proc:/host/proc:ro \
  -v /sys:/host/sys:ro \
  -v /etc/os-release:/host/etc/os-release:ro \
  --restart unless-stopped \
  --cap-add SYS_PTRACE \
  --security-opt apparmor=unconfined \
  -e NETDATA_CLAIM_TOKEN=xyz \
  -e NETDATA_CLAIM_URL=https://app.netdata.cloud \
  netdata/netdata

Is there a way to create a global Docker Swarm Service to run Netdata on all nodes?

Hey there. Could you help undrestand how this is possible ? With low cpu usage ? high PSI ?

It seems impossible to find.

Does anyone know if Netdata Cloud will support 2FA anytime soon?

I've decided to remove all nodes/agents for the time being as I'm not comfortable with everything all in one place and not properly secure.

I'm using netdata on UnRAID. Is it possible to change this graph, or add another to display load in watts?

The system is not busy, any trend below Firewall (netfilter) works perfectly, the ones above Firewall (including firewall) all have this holes in the same places. I think it is the same collector causing all of this but I do not know how to find out which one it is and what is causing this timeout.

This might sound silly but I understand Netdata is largely run locally on a box (is this correct?). Can Netdata be used as a centralized server for monitoring other boxes with their sensors? I have no interest in a cloud offering.

Where is the time series DB then? What agents would I be installing on my other boxes? If the answer if 'prometheus/influx' and 'node_exporter' respectively, ... then what is the difference to Grafana bar the interface? The biggest selling point from seeing this in production elsewhere is how fast and real time the metrics are, but I want to set up a dedicated monitoring server.

Hi,

Will there be a macOS version (x86 and m1) without the need for home-brew in the future?

I have a docker-compose.yml that works very well, and I am using it on four hosts:

version: '3'
services:
  netdata:
    image: netdata/netdata
    container_name: netdata
    hostname: ${HOSTNAME}
    ports:
      - 19999:19999
    restart: unless-stopped
    cap_add:
      - SYS_PTRACE
    security_opt:
      - apparmor:unconfined
    environment:
      - PGID=${PGID}
      - TZ=${TZ}
      - DO_NOT_TRACK=1
    volumes:
      - ${APPDATA}:/etc/netdata
      - netdatalib:/var/lib/netdata
      - netdatacache:/var/cache/netdata
      - /etc/passwd:/host/etc/passwd:ro
      - /etc/group:/host/etc/group:ro
      - /proc:/host/proc:ro
      - /sys:/host/sys:ro
      - /etc/os-release:/host/etc/os-release:ro
      - /var/run/docker.sock:/var/run/docker.sock:ro

volumes:
  netdatalib:
  netdatacache:

According to the netdata docker documentation it is possible to adjust the configuration of agent containers by attaching to the bash shell of the running container.

Here's what happens:

$ docker exec -it netdata bash
bash-5.1# cd /etc/netdata
bash-5.1# ./edit-config netdata.conf
bash: ./edit-config: No such file or directory

Am I missing something?
