netdata
    
    
        real-time performance monitoring
    
    
        scaled out!
    
    
        pick a netdata demo server
    
    
        these demo servers show what you will get by installing netdata
    
    
    
        this page is a custom netdata dashboard
    
    
        charts are coming from 8 servers, in parallel
        
        the servers are not aware of this multi-server dashboard,
        
        each server is not aware of the other servers,
        
        but on this dashboard they are one!
    
    
        
        hover on a chart below, or drag it to show the past - the others will follow!
        
        double click on a chart to reset them all
    
    
        our nginx performance
    
    
        (we proxy netdata through nginx, on the demo sites)

         did you notice the decimal numbers?
        
netdata interpolates collected values at second boundaries, with nanosecond detail!
    
    
        CPU Utilization of the demo sites
    
    
    
         what is using so much CPU?
        
The site iplists.firehol.org is maintained by FireHOL - the CPU is used for comparing security IP Lists.
     
    
        Netdata performance
    
    
        netdata monitors users, user groups, applications (process trees)
        
        containers (lxc, docker, etc.) and SNMP devices.

                 this utilization is about the whole netdata process tree and the percentage is of a single core!
                
including BASH plugins (it monitors mysql on the demo sites), node.js plugins (it monitors bind9 on the demo sites), etc.
                
and including the chart refreshes for the dashboards of all viewers.

                    Canada, API average response time in milliseconds
                
                
                
                
             
            
                 netdata is really fast (the values are milliseconds!)
                
                These values include everything, from the reception of the first byte to the dispatch of the last, including gzip compression.
                
                Values above 2-3ms are usually chart refreshes of charts with several dimensions, charts with very long durations (zoomed out), or file transfers.
