vSTREAM Embedded on Linux

Introduction

 

 

 

This is a simplified installation procedure that meets most customer needs and can be used for installation of any Linux-flavor host cmputer. The complete installation manual can be found on MyNetscout.

 

Solution

Installation

Download or copy the most recent version of the .bin installer to a local directory on the target host, for example use wget to copy the installer to the /tmp directory. The file can be safely removed after completion.

# cd /tmp

# wget https://comcert.box.com/shared/static/something.bin

# mv something.bin is-6110-668-vSTREAM_EMB.bin

# md5sum is-6110-668-vSTREAM_EMB.bin

# chmod +x is-6110-668-vSTREAM_EMB.bin

# ./is-6110-668-vSTREAM_EMB.bin -i console

Should output (example on ubuntu):

Configuration

# cd /usr/lib/NetScout/rtm/config
# vi nsagent_config.cfg

Change "export HTTP_PORT=8080" to "export HTTP_PORT=7080"

Change "export HTTPS_PORT=8443" to "export HTTPS_PORT=7443"

Example:

export NSCOMM_PORT=395
export NSCONSOLE_PORT=1501
export HTTP_PORT=7080
export HTTPS_PORT=7443
export  MON_INF=eth0
export MGMT_INF=eth0

 

Start/Stop

# systemctl restart vstream-emb

or:

# service vstream-emb stop
# service vstream-emb start

Note: restarting the system may take a minute.

 

Test

Verify if services procmana and nsprobe are running

root@ip-10-167-4-92:/usr/lib/NetScout/rtm/bin# ./PS
    user,  pid,  rss,  vsz,  pm,  pc, command
root     30027  3152   4604  0.1  0.0 procmana
root     30030 494664 560080 24.1 7.2 nsprobe

 

Firewall

In case of a firewall, drill holes in the firewall on the host or between host and nGeniusONE Server to allow these sessions:

From nGeniusONE Server (Standalone or Local Server) to host:

• tcp/8080 or tcp/8443 (recommended)
• tcp/1501 (optional but required for Remote Login from nGeniusONE Server to vSTREAM Embedded)

From host to nGeniusONE Server (Standalone or Local Server):

• tcp/395 (optional but required for automatic registation of the vSTREAM Embedded in nGeniusONE Server)
• GRE (IP protocol number 47) or udp/ . Both are optional but it is recommeded to open these ports already.

 

Localconsole

Run the agent configuration utility to add vSTREAM Embedded to NGS.

# cd /usr/lib/NetScout/rtm/bin 
# ./localconsole

 

Rename

Go to NGS > Console > Device Configuration > Devices and change the name of the  vSTREAM Embedded you just added from its UUID to a more meaningfull name (example IS-<hostname>) before continuing to the next installation. 

 

Uninstall

# cd /usr/lib/NetScout/rtm/bin
# ./vscout_uninstall.sh
