Configuring Data Logging from each port on Nodegrid to a Remote NFS Server

Configuring Data Logging from each port on Nodegrid to a Remote NFS Server

This article provides guidance on configuring data logging from managed devices to be stored on a remote NFS server. Data logs capture all information sent to and received from a device.

1. Enabling Data Logging for a Device

This section explains how-to guide for configuring data logging for a port (device) using both the WebUI and CLI, offering detailed instructions to set up logging for your managed devices.

1.1 Configuration via WebUI:

  1. Login as admin and navigate to Managed Devices

  2. Select the target device and go to Logging

  3. Enable Data logging option and Click Save

  4. Go to Access page and select the target device and you will see Data log tab in dialogue for the device

  5. To open the pdf for the logs click Data log




1.2 Configuration via CLI:

  1. Log in as admin in CLI (telnet/ssh/console)

  2. Navigate to /settings/devices/<Device_Name>/logging/

  3. Use the set command to change the data_logging value to yes or no

  4. Commit the changes


    [admin@nodegrid / ] # cd /settings/devices/<Device_Name>/logging/

    [admin@nodegrid logging] # set data_logging=yes

    [+admin@nodegrid logging] commit

    [admin@nodegrid logging]#



2. Sending Data Logs to a Remote NFS Server

This section is a how-to guide for enabling data logging from a device (port) to an NFS server, providing detailed instructions for configuring the transfer process to the remote NFS server.

2.1 Configuration via WebUI:

  1. Login as admin and navigate to Auditing :: Destinations :: File

  2. Select the NFS option from the Destination dropdown.

  3. Under NFS Destination section:

    1. Enter the server IP on the NFS Server field.

    2. Specify the NFS Path where the NFS Server is mounted.

  4. Click Save to apply the configurations


  1. Navigate to Security :: Services :: General Services

  2. Enable the RPC service by checking the checkbox Enable RPC.

    1. “NFS requires RPC service to be enabled in Security :: Services.”



2.2 Configuration via CLI:

  1. Log in as admin via CLI (telnet/ssh/console).

  2. Navigate to /settings/auditing/destinations/file/

  3. Use the set command to change the destination value to NFS

  4. Use the set command to set the Server IP in the nfs_server field

  5. Use the set command on the nfs_server field to enter the path where the NFS Server is mounted

  6. Use the set command in the nfs_path to specify the path where the NFS Server is mounted

  7. Commit the changes

    [admin@nodegrid /]# cd /settings/auditing/destinations/file/

    [admin@nodegrid file]# set destination=nfs

    [+admin@nodegrid file]# set nfs_server=192.168.42.177

    [+admin@nodegrid file]# set nfs_path=/var/opt/nfsroot

    [+admin@nodegrid file]# commit

    [admin@nodegrid file]#


  8. Navigate to /settings/services/

  9. Use the set command to change the enable_rpc value to yes

  10. Commit the changes

    [admin@nodegrid /]# cd settings/services/

    [admin@nodegrid services]# set enable_rpc=yes

    [+admin@nodegrid services]# commit

    [admin@nodegrid services]#

3. Setting Up an NFS Server on Nodegrid

It is possible to use Nodegrid as an NFS server. To set up the NFS server, you need to create an exported folder where the contents of the rootfs will be stored

Enter root shell from admin CLI session: shell sudo su -

First, load the kernel modules nfs and nfsd.

  1.  modprobe nfs
  2.  modprobe nfsd

Create the /var/opt/nfsroot folder, which will be used to store the files.
mkdir /var/opt/nfsroot

Then, edit the exports file on /etc/exports and add at the bottom of the file:
/var/opt/nfsroot *(async,rw,no_root_squash,no_all_squash,no_subtree_check,insecure,anonuid=1000,anongid=1000)

Now, restart the NFS daemon, rpcbind and the server:
exportfs -a
/etc/init.d/rpcbind restart
/etc/init.d/nfsserver restart
