Analytics Deployment;

Analytic is a log collector. it collects logs from appliances and interprets them. Also, it provides lots of information about networks and security.

This information;

  • Traffic and application analysis,

  • Network, security analysis

  • Behavior anomaly detection

Also, it allows us to troubleshoot and determine the source of problems in the network.


I will install the Analytics according to the following topology.

ree

ree

Step 1: Assign IP address on northbound and southbound interfaces from CLI

sudo nano /etc/network/interfaces
ree

ree

Step 2: Configure a static route on Analytics and ensure reachability to 10.0.0.0/8

192.168.200.31: It is the eth1 IP address of Controller

ree

Step 3: Configure hostname in both Versa Director and Analytics

The northbound IP address of the Director is 192.168.252.129

The northbound IP address of Analytics is 192.168.252.132

Step 4: As I changed the hostname of Versa Director during the setup step, I have to generate a new self-signed certificate and register that certificate to the Versa Analytics certificate store. My director hostname; Director01

cd  /opt/versa/vnms/scripts/
sudo -u versa ./vnms-certgen.sh --cn Director01 --overwrite --storepass versa123
ree
ree

Step 5: Restart the versa director services;

vsh restart
ree

Step 6: I define the analytics information to Director

ree

Step 7: Copy and install the certificate to the analytics node on Director

sudo -u versa ./vnms-cert-sync.sh --sync
ree

Director pushes the certificate to analytics. I see the certificate is installed.

ree

Step 8: Check the certificate on Analytics;

and I see all certificates on Analytics.

ree

Step 9: Verify certificates on both director and analytics are correct. I check Director value and Remote value, both values are the same.

cd /opt/versa/vnms/scripts/
sudo -u versa ./vnms-cert-sync.sh -verify
ree

Step 10: Configure Versa Analytics setup on Analytics:

sudo /opt/versa/scripts/van-scripts/vansetup.py
ree
ree

I see the van setup is completed.

ree

Step 11: open GUI

https://192.168.252.132:8443 This IP address is the northbound IP of Analytics

Username :admin

Password:versa123


ree

Step 12: Add the Hostname of Versa Director

After Registering, we will be able to access Analytics, directly from Director Tab


ree

Check the configuration on the Analytics collector, there is no configuration on Analytics.

set log-collector-exporter local collectors analytics address 172.16.1.2 port 1234 transport tcpstorage directory /var/tmp/log format syslog
ree

commit and check configuration ;

ree

Thanks for Reading.
