How much bandwidth is your MDaemon server using?

Networx Bandwidth MonitorI recently found myself working on a project where I needed to calculate how much bandwidth the average MDaemon server uses – I’m hoping if you’re an MDaemon user, you’ll be able to help me out here.

Every server’s usage is different of course – bandwidth will vary depending upon the number of users and the type and the number of emails, but I knew if I could arrive at an average across a handful of customer sites I’d be able to get close enough for my needs.

I started with our own MDaemon server which is hosted in a data centre and initially started thinking along the lines of using some clever Windows power shell scripting or the maybe the performance monitor. I was after a quick solution though and that kind of thing was likely to take some hours to come up with.

Fortunately I remembered a tool from I had used in the past that would allow me to monitor network usage for broadband connections (from ‘back in the day’ when strict data usage caps were more of an issue).

A quick Google later and I had found the latest version of Networx.

Networx is one of those great applications that’s simple to download and run directly from a folder, so no need to install,  and then just does exactly what is said on the tin.. oh and it’s freeware. Bonus!

I wont go through all of the features as its rather self-explanatory but here are a few quick screenshots that give a good overall idea.

Let me know what you’re seeing!

I’ve been running it on a couple of MDaemon servers for a few days now and I’m starting to get an idea of our bandwidth per user, which is great, but I’d really appreciate your findings to make this a little more meaningful.

Please let me know your average bandwidth used figures and the number of MDaemon users either in the comments or via email to neil@zensoftware .

Many thanks!

  1. Great article and something that we had never given that much thought to. Since reading, I’ve installed to our 280 user account instance (150 actual users) and will post some details over the coming days.

      • Now that we’ve had Networx running on the mail server for a week, the below shows our rates.

        Thankfully we use Veeam for the backup of our servers which are all VMware VMs so there isn’t any contamination of the data transferral figures.

        Not huge amounts of traffic granted and the hourly shows that our usage almost falls off a cliff at just before 18:00 and doesn’t really show up again until 08:00.

        • Thanks for this Bob, Its interesting you say its Low usage, can I just ask how many users you have serviced by that server?
          I know for one of our server with 20 users we see an average of 2GB a day so i’m guessing your server is more like 40-50 users, or maybe we have very low usage users compared to yours?

          • Hi Neil,

            We have 120-130 real physical users, with the remaining accounts (a further 150 or so) taken up by shared email accounts akin to public folders. Most of them are fairly light usage but there are one or two that hammer the server. Thankfully our spam is handled brilliantly by SG and we don’t get impacted in that regard.
