    Hello Ravi,

    Good post. I installed on a RedHat Linux server. When I start the service, I see the following message.
    2017-02-22 10:41:38: netdata: ERROR: IPv6 socket() on ip ‘::’ port 19999 failed. (errno 97, Address family not supported by protocol)
    2017-02-22 10:41:38: netdata: ERROR: Cannot bind to ip ‘::’, port 19999
    2017-02-22 10:41:38: netdata: INFO: Listen socket [0.0.0.0]:19999 opened.

    I cannot connect from a browser when I tried http://linux-hostname:1999
    Can you please suggest?

    • Ravi Saive says:

      @Shashi,

      It seems that it couldn’t bind on IPv6 port due to firewall restrictions, I suggest you to check your firewall rules and open port 19999 on firewall or open it for IPv4.

      You can verify the port by running netstat command.

      # netstat -antp | grep LISTEN | grep 19999

        Hi Ravi,

        I am trying this on a sandbox environment and asking the networking team for firewall rules change would be quite challenging and time consuming.

        Is there a way I can find:

        1) an open port that’s not blocked by the firewall and
        2) change the default 19999 port to a different one?

        Thanks

    Do you know if this app can monitor other machines of which its not installed on? Also this would be cool to integrate into ddwrt.

    • Ravi Saive says:

      @David,

      Unfortunately, Netdata application is not designed to monitor remote Linux machines and nor its possible to integrate it with any other tool..

    When I try to install on RHEL 7 it shows the following error ,

    ” Sorry! NetData failed to build…

    You may need to check these:

    1. The package uuid-dev (or libuuid-devel) has to be installed.

    If your system cannot find libuuid, although it is installed
    run me with the option: –libs-are-really-here

    2. The package zlib1g-dev (or zlib-devel) has to be installed.

    If your system cannot find zlib, although it is installed
    run me with the option: –libs-are-really-here

    3. You need basic build tools installed, like:

    gcc make autoconf automake pkg-config

    Autoconf version 2.60 or higher is required.

    If you still cannot get it to build, ask for help at github:

    https://github.com/firehol/netdata/issues

    What can I do now?

    • Ravi Saive says:

      @Narayan,

      Please find install the missing dependency packages as shown in the article, before installing Netdata tool, here is the command to install those missing packages.

      # yum install zlib-devel gcc make git autoconf autogen automake pkgconfig uuid-dev 
      
    • Superior says:

      @Narayan, 1st run yum install libuuid-devel
      then yum install zlib-devel
      and then run installer with following command
      ./netdata-installer.sh –libs-are-really-here

      Hope this will solve your issue.

      Thanks

    Hello Ravi,
    Thanks for the tutorial. I have installed it on 3 different servers. 1 of them is showing Firewall (Netfilter) data but other 2 are not showing this option. I have repeated the same steps on all servers. Can you please guide how to enable firewall plugin on other 2 servers?
    Thanks

    • Ravi Saive says:

      @Umar,

      On the other servers, the firewall service is running? could you share the screenshots of other servers? so that we check and provide you a solution..
