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.

That reminded us of the few issues we had with the firewall and anitivirus. We checked the firewall and antivirus on the server. Firewall was disabled, but Symantec antivirus was running. Once we stopped the antivirus, we could receive responses from the devices for the SNMP requests sent from OpManager server. We were bewildered, at the same time very eager to know about why SNMP requests sent from ManageEngine applications are blocked, when the same from the other MIB browser could pass through. We analyzed both the MIB Browsers in-depth. The difference was the platform that they were built on. Our's were built on Java, while the other one was built on .Net. We did some quick research and found that antiviruses block SNMP requests when sent from Java based applications.

Have you folks come across the same? Feel free to share your experiences and thoughts.

This is the second time we had an issue with antivirus. The first one was with McAfee. It didn't allow MySQL of OpManager 8 to start. We did some changes in the McAfee policies to get it working. Please check this link if you haven't checked it before. If you face any such issues, try disabling the firewall and anti-virus during startup which should work.

“I used a lot of products in the past but I don’t remember a product that was as useful as ServiceDesk Plus to administer all the problems that I have in my network and also the OpManager.. Sometimes when I have a server that’s unavailable, I can act before a user lets me know that I had a problem.” Jesse Gusmao Ferreira, from Hospital Samaritano, Sao Paulo, Brazil.

We're all ready to talk network management after that hiatus on our blogs. Truth is we're suddenly finding ourselves doing a lot of work n a lot less of talk. Is that related to the recession? The papers, television, internet, radio - everyone's onto the recession. I can't wait for it all to get over - the pretty faces on TV look so sad when presenting the news!

Well, 2008 has been a good year for OpManager. A year that's made us put in the extra sweat to bring out additions in the product, in line with our goal of becoming THE complete IT infrastructure monitoring platform. The Distributed Edition of OpManager, now with VMware monitoring included, found customers within a month of product launch. We pushed ourselves in the network monitoring front by adding traffic flows monitoring and VoIP performance monitoring. 2009 is even going to see greater efforts spent in making the network admin's life a whole lot easier.

I'll sign off for now with a bit on OpManager 8 that's coming out very soon. OpManager 8 is sure to make network management a piece of cake with a number of options to customize the product to your monitoring needs. You just have to get a hold of it when it's out.

Thank you 2008. And 2009, here we come!

2008 - Highlights:

We at ManageEngine are always game for opportunities that allow us to meet with the people who care about IT. This time round we thought we'd do something big to spend quality time with our customers, users, partners and any soul who cares about Networks, servers, applications, systems, the works. We would like to welcome you all to our ManageEngine Euro Roadshow conducted with the help of our partners throughout Europe from the 8th of September to October the third.

We very look forward to meeting you!

Todd Weiss of ComputerWorld has an interesting article about how people are “on mission” at the LinuxWorld Conference & Expo. Consultants, CEOs, CIOs, IT Managers, Administrators - everyone’s looking for applications, services and systems that deliver more and more, at less cost. Todd quotes Adam Talbot, a Linux and Unix administrator with the Lawrence Livermore National Laboratories in Livermore, Calif.:

“I’m always looking for the next (big) thing… If I can find a solution that beats all of our stuff, costs less and is more applicable to our environment, then that’s what I’m looking for.”

With all the new features and add-ons OpManager’s been going through, this excerpt from Todd’s article truly encourages us

Talbot now uses OpManager from AdventNet Inc. after moving away four months ago from competing applications from the Nagios open-source project and GroundWork Open Source. While neither of those products had major shortcomings, Talbot wants something that offers more monitoring services for various operating systems, including SNMP (Simple Network Management Protocol).

“We’re always looking for more for less,” Talbot said.

Thanks very much Talbot and Todd. We’ll continue giving you more in our network monitoring software, OpManager!

65Watts + 75Watts * 8760 hours / 1000 = 12264 kW hours
12264kW hours * 11.53 /100 * 500 * 5years = $353,505

The standard business hours 9AM-6PM Monday to Friday contribute just 27% of the overall available time. 
And in these 45 hours, reports indicate that, only 60% of the time the desktops are actively used. Rest goes in breaks, phone calls, meetings, and discussions. If someone enables strict power management ** for the above case, it will result in a savings of approximately $300k

 $353,505 * 0.73 = $258,058 (for non-working hours)
 $353,505 * 0.27 * 0.4 = $38,178 (for 40% idle time on office hours)
Total: $258,058+$38,178 = $296,236

*Thermal Design Power of E2160 is 65Watts. For monitors its 75Watts. 65+75*8760 hours /1000 =12264 kW hour. Refer Wikipedia for TDP of other processors.

Are you new to the critical, downtime-equals-revenue lost world of network management? Are you overwhelmed with where to begin, what to monitor, how to manage, who to notify, how to troubleshoot?

Would you like to know how best to use ManageEngine OpManager right from its installation? Want to know what are the maintenance practices, the upgrade procedures & benefits of integrating with other ManageEngine solutions?

We’ve planned a training programme for those who’d like to have that crucial head-start in effectively using OpManager. The ManageEngine training team begins classroom training sessions at the AdventNet office in Austin, Texas from the 14th of this month. The details:
