+# Netdata registry
 
 Netdata registry implements the `my-netdata` menu on netdata dashboards.
 The `my-netdata` menu lists the netdata servers you have visited.
 
 ## Why?
 
-netdata provides distributed monitoring.
+Netdata provides distributed monitoring.
 
 Traditional monitoring solutions centralize all the data to provide unified dashboards across all servers. Before netdata, this was the standard practice. However it has a few issues:
 
 1. due to the resources required, the number of metrics collected is limited.
-2. for the same reason, the data collection frequency is not that high, at best it will be once every 10 or 15 seconds, at worst every 5 or 10 mins.
-2. the central monitoring solution needs dedicated resources, thus becoming "another bottleneck" in the whole ecosystem. It also requires maintenance, administration, etc.
-3. most centralized monitoring solutions are usually only good for presenting *statistics of past performance* (i.e. cannot be used for real-time performance troubleshooting).

+Netdata follows a different approach:
 
 1. data collection happens per second
-2. thousands of metrics per server are collected
-3. data do not leave the server where they are collected
-4. netdata servers do not talk to each other

-Using netdata, your monitoring infrastructure is embedded on each server, limiting significantly the need of additional resources. netdata is blazingly fast, very resource efficient and utilizes server resources that already exist and are spare (on each server). This allows **scaling out** the monitoring infrastructure. 
+Using netdata, your monitoring infrastructure is embedded on each server, limiting significantly the need of additional resources. Netdata is blazingly fast, very resource efficient and utilizes server resources that already exist and are spare (on each server). This allows **scaling out** the monitoring infrastructure.
 
 However, the netdata approach introduces a few new issues that need to be addressed, one being **the list of netdata we have installed**, i.e. the URLs our netdata servers are listening.
 
-To solve this, netdata utilizes a **central registry**. This registry, together with certain browser features, allow netdata to provide unified cross server dashboards. For example, when you jump from server to server using the `my-netdata` menu, several session settings (like the currently viewed charts, the current zoom and pan operations on the charts, etc) are propagated to the new server, so that the new dashboard will come with exactly the same view.

-`allow from` settings are [netdata simple patterns](https://github.com/netdata/netdata/wiki/Configuration#netdata-simple-patterns): string matches that use `*` as wildcard (any number of times) and a `!` prefix for a negative match. So: `allow from = !10.1.2.3 10.*` will allow all IPs in `10.*` except `10.1.2.3`. The order is important: left to right, the first positive or negative match is used.

 Keep in mind that connections to netdata API ports are filtered by `[web].allow connections from`. So, IPs allowed by `[registry].allow from` should also be allowed by `[web].allow connection from`.
