Netdata collects metrics per second & presents them in low-latency dashboards. It is designed to run on all physical & virtual servers, cloud deployments, Kubernetes clusters, and edge/IoT devices, to monitor your systems, containers & applications.
Scales nicely from a single server to thousands of servers, even in complex multi/mixed/hybrid cloud environments & given enough disk space it can keep your metrics for years.
KEY FEATURES:
💥 Collects metrics from 800+ integrations OS metrics, container metrics, VMs, hardware sensors, apps metrics, OpenMetrics exporters, StatsD & logs.
💪 Real-Time, Low-Latency, High-Resolution All metrics are collected per second & are on the dashboard immediately after data collection. Netdata is fast.
😶🌫️ Unsupervised Anomaly Detection Trains multiple ML models for each metric collected & detects anomalies based on the past behavior of each metric individually.
🔥 Powerful Visualization Clear & precise visualization that allows you to quickly understand any dataset, but also to filter, slice & dice the data directly on the dashboard, without the need to learn any query language.
🔔 Out of box Alerts Hundreds of alerts out of the box to detect common issues & pitfalls, revealing issues that can easily go unnoticed. It supports several notification methods to let you know when your attention is needed.
📖 systemd Journal Logs Explorer (BETA - nightly release channel) Provides a systemd journal logs explorer, to view, filter & analyze system & apps logs by directly accessing systemd journal files on individual hosts & infrastructure-wide logs centralization servers.
😎 Low Maintenance Fully automated in every aspect: automated dashboards, out-of-the-box alerts, auto-detection & discovery of metrics, zero-touch ML, easy scalability, high availability &CI/CD friendly.
⭐ Open & Extensible Netdata is a modular platform that can be extended in all possible ways and it also integrates nicely with other monitoring solutions.

Pros are instant HA and Migration. Cons are huge bandwidth hits. With your 4x1gbe you would be maxed out on replicating those 25 VMs. You wouldn't have anything for users. I have a test lab with 4 nodes, 22cpu 100gbram and 30tb space, using low end stuff, 12hdds. Proxmox, ceph dashboard, (the native ceph dashboard you can turn on), and a netdata.cloud account. So I watch it like a hawk and like to load test. Source: over 1 year ago
Docker-compose, not k8s. Set up a script to update the OS, pull all your containers and reboot after hours once a week or once a day. Make sure the script specifies non interactive. Set up alerting for low disk space, see https://netdata.cloud or use your own tool. - Source: Hacker News / over 2 years ago
There can be some issues if you mix and match elastic versions, wazuh versions, logstash versions. But the documentation guides you very well with matrix of what is and is not compatible. You will want a beefy VM to run it in, I started smaller than I should of, and after running a while it kind of puked on itself, certain things would randomly stop working. After giving it 32GB RAM, plenty of disk 4TB, and 8... Source: over 2 years ago

What I know is that each node's data is still primarily stored on the node itself, and I've figured that the Registry used by Netdata cloud stores only URLs and randomly generated UUIDs. So my question is, will any other data be stored outside of my nodes? Does Netdata Cloud have access to my servers 24/7 or only when I got a browser tab with Netdata cloud open? Is there more information on security and data... Source: about 3 years ago
Https://collectd.org/ does the gathering (and writing to RRDTool database, if you so desire) part very well. Many plugins, easy to add more (just return one line of text) Still need RRD viewere but that's not a huge stack And it scales all the way to hundreds of hosts, as on top of network send/receive of stats it supports few other write formats aside from just RRD files. - Source: Hacker News / 7 months ago
Why not use https://collectd.org/ which is in C and used by openwrt's luci already along with rrdtool, small in size, low on resource, and has so many plugins already? - Source: Hacker News / 7 months ago
Then you will have same problems but now you can bother manufacturer about it! Also unless there is something horribly wrong about how often data is written, that SSD should run for ages. We ran (for a test) consumer SSDs in busy ES cluster and they still lasted like 2 years just fine The whole setup was a bit of overcomplicated too. RAID10 with 5+1 or 7+1 (yes Linux can do 7 drive RAID10) with hotspare woud've... - Source: Hacker News / over 1 year ago
Collectd pulls metrics from the OS, applications, logfiles and external devices for use in monitoring systems, finding performance bottlenecks and capacity planning. Hombre_sabio explains, "Collectd is a tiny daemon that gathers information from a system. It enables mechanisms to collect and observe the values in different techniques. It is an open-source monitoring tool to retrieve and manage SNMP master agents.". Source: over 1 year ago
For metrics storage I'm using a Graphite database and the graph UI itself is Grafana. To get these I'm using the Debian repos they supply with mostly off-the-shelf configs. For collecting metrics from the Pi to send to Graphite I use collectd. It has a lot of off-the-shelf plugins you can use to grab metrics like CPU usage & load average, network in/out, memory stats etc. The Minecraft-specific stuff you can get... Source: over 2 years ago
