A Netdata Parent is a Netdata Agent that has been configured to accept streaming connections from other Netdata agents.
Netdata Parents provide:
- Infrastructure level dashboards, at
http://parent.server.ip:19999/ - Increased retention for all metrics of all your nodes
- Central configuration of alerts and dispatch of notifications
You can also use Netdata Parents to:
- Offload your production systems (the parents runs ML, alerts, queries, etc for all its children)
- Secure your production systems (the parents accept user connections, for all its children)
Optionally, sign-up to Netdata Cloud and claim your Netdata Parents.
When your parents are connected to Netdata Cloud, you can (on top of the above):
- Organize your infra in spaces and rooms
- Create, manage, and share custom dashboards
- Invite your team and assign roles to them (Role Based Access Control - RBAC)
- Access Netdata Functions (processes top from the UI and more)
- Get infinite horizontal scalability (multiple independent parents are viewed as one infra)
- Configure alerts from the UI (coming soon)
- Configure data collection from the UI (coming soon)
- Netdata Mobile App notifications (coming soon)
🤟 Netdata Cloud does not prevent you from using your Netdata Agents and Parents directly, and vice versa.
👌 Your metrics are still stored in your network when you connect your Netdata Agents and Parents to Netdata Cloud.
Netdata is built around a modular metrics processing pipeline.
Each Netdata Agent can perform the following functions:
-
COLLECT
Uses internal and external plugins to collect data from their sources.Netdata auto-detects and collects almost everything from the operating system: including CPU, Interrupts, Memory, Disks, Mount Points, Filesystems, Network Stack, Network Interfaces, Containers, VMs, Processes, SystemD Units, Linux Performance Metrics, Linux eBPF, Hardware Sensors, IPMI, and more.
It collects application metrics from applications: PostgreSQL, MySQL/MariaDB, Redis, MongoDB, Nginx, Apache, and hundreds more.
Netdata also collects your custom application metrics by scraping OpenMetrics exporters, or via StatsD.
It can convert web server log files to metrics and apply ML and alerts to them, in real-time.
And it also supports synthetic tests / white box tests, so you can ping servers, check API responses, or even check filesystem files and directories to generate metrics, train ML and run alerts and notifications on their status.
-
STORE
Uses database engine plugins to store the collected data, either in memory and/or on disk. We have developed our owndbenginefor storing the data in a very efficient manner, allowing Netdata to have less than 1 byte per sample on disk and amazingly fast queries. -
LEARN (ML)
Trains multiple Machine-Learning (ML) models per metric to learn the behavior of each metric individually. -
DETECT (ML)
Uses the trained machine learning (ML) models to detect outliers and mark collected samples as anomalies. Netdata stores anomaly information together with each sample and also streams it to Netdata Parents so that the anomaly is also available at query time for the whole retention of each metric. -
CHECK
Uses its configured alerts to check the metrics for common issues and send alert notifications. -
STREAM
Push metrics in real-time to Netdata Parents. -
ARCHIVE
Export metrics to industry standard time-series databases, likePrometheus,InfluxDB,OpenTSDB,Graphite, etc. -
QUERY
Provide an API to query the data and present interactive dashboards to users.
When using Netdata Parents, all the functions of a Netdata Agent (except data collection) can be delegated to Parents to offload production systems.
Of course it is! We do our best to ensure it is!
We understand that Netdata is a software piece that is installed on millions of production systems across the world. So, it is important for us, Netdata to be as secure as possible:
- We follow the Open Source Security Foundation best practices.
- We have given great attention to detail when it comes to security design. Check out our security design.
- Netdata is a popular open-source project and is frequently tested by many security analysts.
- Check also our security policies and advisories published so far.
No. It will not! We promise this will be fast!
Although each Netdata Agent is a complete monitoring solution packed into a single application, and despite the fact that Netdata collects every metric every single second and trains multiple ML models per metric, you will find that Netdata has amazing performance! In many cases, it outperforms other monitoring solutions that have significantly fewer features or far smaller data collection rates.
This is what you should expect:
- For production systems, each Netdata Agent with default settings (everything enabled, ML, Health, DB) should consume about 5% CPU utilization of one core and about 150 MiB or RAM. By using a Netdata parent and streaming all metrics to that parent, you can disable ML & health and use an ephemeral DB mode (like
alloc) on the children, leading to utilization of about 1% CPU of a single core and 100 MiB of RAM. Of course, these depend on how many metrics are collected. - For Netdata Parents, for about 1 to 2 million metrics, all collected every second, we suggest a server with 16 cores and 32GB RAM. Less than half of it will be used for data collection and ML. The rest will be available for queries.
Netdata has extensive internal instrumentation to help us reveal how the resources consumed are used. All these are available in the "Netdata Monitoring" section of the dashboard. Depending on your use case, there are many options to optimize resource consumption.
Even if you need to run Netdata on extremely weak embedded or IoT systems, you will find that Netdata can be tuned to be very performant.
As much as you need!
Netdata supports tiering, to downsample past data and save disk space. With default settings, it has 3 tiers:
tier 0, with high resolution, per-second, data.tier 1, mid-resolution, per minute, data.tier 2, low-resolution, per hour, data.
All tiers are updated in parallel during data collection. Just increase the disk space you give to Netdata to get a longer history for your metrics. Tiers are automatically chosen at query time depending on the time frame and the resolution requested.
Yes, of course it does!
✈️ Netdata Parents provide great vertical scalability, so you can have as big parents as the CPU, RAM and Disk resources you can dedicate to them. In our lab we constantly stress test Netdata Parents with about 2 million metrics collected per second.- 🚀 In addition, Netdata Cloud provides virtually unlimited horizontal scalability. It "merges" all the Netdata parents you have into one unified infrastructure at query time. Netdata Cloud itself is probably the biggest single installation monitoring platform ever created, currently monitoring about 100k online servers with about 10k servers changing state (added/removed) per day!
Yes, you can!
We suggest the following:
- Use database mode
allocorramto disable writing metric data to disk. - Configure streaming to push in real-time all metrics to a Netdata Parent. The Netdata Parent will maintain metrics on disk for this node.
- Disable ML and health on this node. The Netdata Parent will do them for this node.
- Use the Netdata Parent to access the dashboard.
Using the above, the Netdata Agent on your production system will not need a disk.
First we have to say that Prometheus as a time-series database and Grafana as a visualizer are excellent tools for what they do.
However, we believe that such a setup is missing a key element: A Prometheus and Grafana setup assumes that you know everything about the metrics you collect and you understand deeply how they are structured, they should be queried and visualized.
In reality this setup has a lot of problems. The vast number of technologies, operating systems, and applications we use in our modern stacks, makes it impossible for any single person to know and understand everything about anything. We get testimonials regularly from Netdata users across the biggest enterprises, that Netdata manages to reveal issues, anomalies and problems they were not aware of and they didn't even have the means to find or troubleshoot.
So, the biggest difference of Netdata to Prometheus and Grafana, is that we decided that the tool needs to have a much better understanding of the components, the applications and the metrics it monitors.
-
When compared to Prometheus, Netdata needs for each metric much more than just a name, some labels and a value over time. A metric in Netdata is a structured entity that correlates with other metrics in a certain way, has specific attributes that depict how it should be organized, treated, queried and visualized. We call this the NIDL (Nodes, Instances, Dimensions, Labels) framework. To maintain such an index is a challenge: first because the raw metrics collected do not provide this information, so we have to add it, and second because we need to maintain this index for the lifetime of each metric, which with our current database retention, it is usually more than a year.
-
When compared to Grafana, Netdata is fully automated. Grafana has more customization capabilities than Netdata, but Netdata presents fully functional dashboards by itself and most importantly it gives you the means to understand, analyze, filter, slice and dice the data without the need for you to edit queries or be aware of any peculiarities the underlying metrics may have. Furthermore, to help you when you need to find the needle in the haystack, Netdata has advanced troubleshooting tools provided by the Netdata metrics scoring engine, that allows it to score metrics based on their anomaly rate, their differences or similarities for any given time-frame.
Despite all these, Netdata integrates nicely with Prometheus and Grafana and we have reports from users who use Netdata with Prometheus and Grafana in production.
No. But we hope you will find it useful.
The Netdata Agent dashboard and the Netdata Cloud dashboard are the same. Still, Netdata Cloud provides additional features, that the Netdata Agent is not capable of. These include:
- Customizability (custom dashboards and other settings are persisted when you are signed in to Netdata Cloud)
- Configuration of Alerts and Data Collection from the UI (coming soon)
- Security (role-based access control - RBAC).
- Horizontal Scalability ("blend" multiple independent parents in one uniform infrastructure)
- Central Dispatch of Alert Notifications (even when multiple independent parents are involved)
- Mobile App for Alert Notifications (coming soon)
So, although it is not required, you can get the most out of your Netdata installation by using Netdata Cloud.
