Review of Free Download Manager

I found Free Download Manager (FDM) to be faster than the built-in Java-based download manager when downloading VMware product. It also has the MD5 check built-in. To me, this is now a better and faster way to download VMware products from

I used it as recently some products cannot be downloaded by the built-in download manager. I got the following error.

DLM java issue

I checked the reason, and found that it’s a known issue here.


So I fell back to the single-thread download. But after 24 hours and different browsers, it was not able to download.

2 Mozilla failed in normal download

Speed of download is low

I guess when a problem came, it could actually be an opportunity to learn something, and experience something better. I would not have learned about this great FDM if not for the issue I encountered.

You can use the full or Lite version. Both are free. I use the Lite as I do not need the rest.

Download this one

The UI is pretty easy. You can see each download. I only have 1 on the following screen as I was testing it first.

Free DM 1

I wrote earlier that it’s faster. Look at the screenshot below. Now that’s MUCH faster than the 125 KB/s I got from the single-thread download. You can see it’s opening multiple threads

Free DM 2

You can drill deeper to see the actual threads. I’m surprised to see it actually opened 14 threads!

21 Free DM opens 14 sessions

You can control the settings if you are concerned about bandwidth. It has a lot of settings!

30 settings

One thing I like is the built-in file integrity check. It will do it automatically once download completed, but you need to specify it manually.

Manual check if you forgot

Here is where you set it.

MD5 Sum check

After I validated that the download was correct, I tried the multiple download. You can see below it’s downloading 2 products.


If you see an error message on the access denied in a few of your threads, you can ignore it. I’m not sure why, but it did not impact the result. I specified the User ID and password in FDM, although I don’t know if it’s required.

wrong passowrd

Overall, I’d give 5/5. Very pleased with it.

VMware CTO Ambassadors in Asia Pacific

Quoting from the official page at, “The CTO Ambassador program is run by the VMware Office of the CTO. The CTO Ambassadors are members of a small group of our most experienced and talented customer facing, individual contributor technologists. They are pre-sales systems engineers (SEs), technical account managers (TAMs), professional services consultants, architects and global support services engineers. The ambassadors help to ensure a tight collaboration between R&D and our customers so that we can address current customer issues and future needs as effectively as possible.”

For more info, see here

With that, here are your Ambassadors for the Asia Pacific region for 2016. We form a small community and work closely together. There are only 28 of us spread across Asia Pacific and we work closely with R&D. Reach out to them via LinkedIn, Twitter, or their personal blogs. If you need their email, you can ask your local VMware representative.

vRealize Operations 6.2 upgrade

Just a few months after the 6.1 release, the product team has released vRealize Operations 6.2. You can find many articles about it by bloggers, such as one this and this. Someone going with the YouTube ID of VirtualXpress IN has even done a video on the upgrade.

Check the known issue here. Also, check the relevant KB, such as this one. For my case, the disk space looks relevant, so I ensure I have enough space first. There are a set of issue on cluster management, none relevant for me as my customers find vSphere HA as sufficient. For an environment with <5000 VM, I think a single node is sufficient. Speaking of high availability, I’d rather have 1 vRealize Operations VM protected by SRM then 2-node cluster without SRM.

Take note of the “Redirecting syslog files to the Log Insight feature also redirects garbage collection files” issue. While I have sufficient space in my Log Insight instance, I do not want it to be cluttered with information that I do not need.

There is an issue with Report Template tab toolbar in using IE 11. In general, I avoid IE for vRealize Operations as I’ve seen the performance delta.

The Release Notes provides tips that if you have a remote environment in which the latency is > 20 milliseconds, you should install a remote collector. I prefer to deploy an appliance instead of Windows as remote collector so I can stick to just 1 common platform for vRealize Operations.

Here are other known issue from the Release Notes that I’m taking note, just in case I see them in my engagements.

  • Some vSphere 6 diskspace metrics do not appear
    Only the following diskspace metrics are published to vRealize Operations from vSphere 6.
    Virtual machine: diskspace|used, diskspace|diskused, diskspace|snapshot
    Host: diskspace|used, diskspace|diskused, diskspace|snapshot
    Cluster: diskspace|used, diskspace|diskused, diskspace|snapshot
    Datastore: diskspace|used, diskspace|diskused, diskspace|snapshot, diskspace|swap, diskspace|capacity, diskspace|disktotal, diskspace|provisioned
  • Metric for Outstanding I/O requests might be inaccurate on some object types
    The datastore|demand_oio metric that appears as Datastore|Outstanding I/O Requests in the UI, might be inaccurate for the vCenter Server, Datacenter, Cluster, and Datastore object types. Due to the method used to calculate a weighted average of transactions and the latency of transactions across hosts, the value of this metric might be artificially high.
  • Deselecting Read permissions for Resources and Dashboards has no effect
    When you create a user role with no Read permission for Resources and Dashboards, the user can still see the dashboards and all resources on the home page. Object Relationships page is always visible to the user with or without any permission.
  • A PDF report file might not include all data from a widget that has a scrollbar

BTW, I’m upgrading from 6.1 Patch. I no longer have earlier edition running around 🙂

The screenshot below is to show you that the upgrade process picked up when I forced stop the upgrade process as I thought it hang. Glad to know it was able to pick up! I clicked Finish installation button.


It took me to this screen, which is by now a familiar screen if you have done multiple update. The keyword here is OS. You need to update the SuSE Linux first. Tomas Baublys wrote a good guide here.


If you leave the browser screen alone, it will timeout after several minutes. Don’t worry, you can log back in and see that upgrade is on-going.


In my case, it was just a 5-10 minutes, and it’s done. This is what it looks like.


Once the base SuSE Linux is updated, time to update the vR Ops application. I shared the process to update from version 6.0 to version 6.0.1 here, and from 6.0 to 6.1 here. The process to update to 6.2 is the same, so kindly review the above. No need to fill the Internet with duplicate info 🙂

11 February 2016 update: There is a patch release called 6.2.0a. See the release notes here
