Re: AirWave 8.2.5: Can I control disk space used by AW server?

I did install AW from an ISO for VMware - is that what you're calling "OVA"?

Re: AirWave 8.2.5: Can I control disk space used by AW server?

On the support site, there's 3 files.

*.tar.gz = upgrade package

*.iso = install iso

*.ova = install ova

 

If you use'd the ISO file, then you should have had an option at the OS install splash to enter 'manual' to allow for customizing the disk partitioning and RAM allocation.  If you ran 'install' it will default to a split calculated based on allocated disk space and RAM.  The default will usually take 2/3 for RAM, and then 1/3 into swap.

Re: AirWave 8.2.5: Can I control disk space used by AW server?

 I did install "AMP-8.2.5-x86_64.iso", but being totally new to AW I wouldn't have known about the manual setup options, nor would I know how to partition memory space.

 

So in my case, since I allocated 8GB RAM in VMware for this AW vm, for some reason it allocated a 50/50 memory/swap.  Is there any way to change it?   If not, I might try a fresh install and do the manual setup.  I'm a bit puzzled as to why the default settings wouldn't handle 10 devices (with 1 AP having 12 clients).  I do have to say, the GUI is slow as mollasses :(

 

But as I think back, I believe I initially only allocated 4 or 6GB RAM to the vm.  And initially I installed it in a datastore that resided on a NAS unit rather than my Dell PE server.  Once I saw that AW looked promising, I used the VMware vCenter Converted Standalone utility to copy the AW vm on to my Dell server's datastore.  I think I noticed that the copied AW vm no longer reported the os to be Linux - instead it simply says "Other (32-bit)".

 

Maybe I should delete this copied vm and start fresh?

Can I export the devices I've configured into AW so far, install a new AW vm, then import from that saved device list?

It usually depends on the VHost setup.

 

To save what you've done so far, grab a backup from System -> Backups.  If you've made changes since the last nightly maintenance time, you could force a backup from the AMPCLI menu - then SCP the file to a remote server (any linux server running sshd, or you can install bitvise sshd onto your win laptop, if on a Mac, you might have to update the ciphers to make scp work).

 

Then after fresh installing a new instance, upload the file - you have to initialize the SCP from AMP to the remote host to pull the file.  And then restore that backup file.

 

Workflow isn't great right now, but there's improvements already planned for 8.2.6 that will help alleviate some of the shortcomings.

Re: AirWave 8.2.5: Can I control disk space used by AW server?

This is interesting: I powered down the AW guest vm, then edited the VMware settings for the os - changing it to Linux, CentOS 4/5/6 (64-bit).  It was previously set at Other - unknown.  I then powered up the AW vm, but I'm unable to see any console - just black screen.  I figured that meant the os never booted.  Just for kicks I tried to log into the AW GUI - and got in!  It also seems a good bit faster on most of the pages.

 

The ISO's filename I installed suggests it's boith x86 and x64 - so how do I know what actually got installed?

 

Thanks for all your assistance!

If you hit System -> Performance, it should show you the kernel info.  Here's an example from one of my lab AMPs.  The whole kernel section is extracted into a pretty format from parsing the unix 'uname' cmd output.  x86_64 translates into 64-bit architecture.

The CLI should still be reachable though if the UI is reachable.  The CLI frame might be in sleep mode, you can try hitting space bar to see if that wakes the prompt back up.

Re: AirWave 8.2.5: Can I control disk space used by AW server?

OK, I was confused by the x86_64 - looked like it meant either x86 or 64 :)  So mine is 64 bit, and that's what the vm is configured for...

 

I guess AMP needed to rest overnight, as now the CLI is working.  But I still see the out of memory errors.  There's no way to partition memory and swap space differently post install, right?  Is there an English translation as to what those OOM messages mean?  It seems to be "killing" processes that always mention "httpd" - what are those processes?  And when I look at the rest of the OOM messages, it looks to be reporting the amounts of memory used by various things:

 

e.g. total-vm: 3,478,496kB,  anon-rss: 63,052kB,  file-res: 176kB

 

I'm guessing the first one is total memory used by vm (the AW guest vm under ESXi?).  That's showing about 3.5GB.  Add in the other two amounts and it's under 4GB.  And I guess I only have 4GB to play with, as the other 4GB is dedicated to swap space and does not count?

The httpd is apache process which serves up the UI and has children processes for other background processing of widgets.

 

It's possible some of the RAM might be lost due to VM overhead.  I prefer VMware 5.5 since I'm not a fan of the newer UI in 6.5.  I feel that things got a lot slower on my servers that were updated to 6.5 and I lose connectivity to those instances frequently.

 

I also find it somewhat surprising that the minimum sizing isn't working for you.  Though I've been typically allocating 4 CPU, 16 GB RAM, and 80 GB disk and never hit more than 5 devices being monitored (another team member handles the scale testing).  But my instances also don't live longer than a few months at most.

Re: AirWave 8.2.5: Can I control disk space used by AW server?

Yes, ESXi 4.1 has worked beautifully for me for years, it's free, so I haven't bothered to upgrade.  I know that all too often "new" features come at a price - bloated code...

 

Would be nice if Aruba came out with a "light" version of AW.  I'm probably only going to use a tiny fraction of it's capabilities, so a lighter version would probably be much faster as far as the GUI.  Hmmm - are there some services I could disable to lighten the memory load of AW server?
