Hi Everyone,

Here is a step-by-step screenshot presentation on How to enable SNMP on Windows Servers. Hope you find this useful.

This is just a new initiative and more to follow from now…

If you are a beginner trying to understanding what is SNMP?  Then I’m sure you will find our SNMP Tutorial informative. Check the tutorial at "http://www.manageengine.com/products/opmanager/what-is-snmp.html"

Quite often we get this query from our evaluators and customers. We already have this data exposed in the OpManager knowledgebase; however I thought it would be nice to do a blog on it as well.

To analyze bandwidth consumption, we ran OpManager in an isolated environment and monitored the devices as listed below

1. 100 Servers (includes service monitoring like Web, MySQL, FTP, SMTP, HTTPS)
2. 3 Switches (each had 24 Ports).
3. 3 Routers (each had 5 Interfaces).
4. 2 Firewalls (each had 3 interfaces).
5. 2 Printers

Servers are monitored through WMI with default monitors (CPU, Memory & Disk) associated.

Monitors like CPU, Memory and Interfaces Rx & Tx Traffic/ Utilization/ Errors/ Discards are associated to Network Devices (like Switches, Routers, Printers and Firewalls) by default.

Monitoring Interval is set to 1 minute for all monitors and the status polling is also set to 1 minute.

Here is the report for you...

UDP Traffic: 5225 bps

TCP/ WMI Traffic: 39435 bps

ICMP Traffic: 1980 bps (18 bps per device)

So, OpManager generates a total traffic of approximately 47Kbps within the LAN in order to monitor 100 Servers, 3 Routers, 3 Switches, 2 Firewalls and 2 Printers.

Hope you find this information useful. 

One more info…Recently, we brought out a new SNMP tutorial for beginners.  Do check out the animated gifs to explain SNMP communication for various commands like GET, TRAP and INFORM.
