AWave newbie: console showing out of memory errors

Hi All,

I'm new to AW, as well as Linux.  So I'm totally baffled by these out of memory error messages I see on AW console: AW Out of Memory.jpg

I installed AW about a month ago, using an .iso for installing it on ESXi 4.1 running on a Dell PE T610 server.  AW lists version 8.2.5.  My ESXi config has 6GB memory, 40GB disk.  I only have about 8 devices added to AW so far, so why would there be any memory issues at this early stage?

 

TIA,

Mike

And below is the Resource Allocation tab data for this virtual AW server on ESXi 4.1:

Hi Mike,

 

We need to reserver the resources to Airwave instance, I see from screen shot memory is not reserverd to this instance.

 

We do not recommand shared memory, try reserver the resources and check the status.

Hi Pavan,

I'm not sure what you mean by "reserver the resources to Airwave instance"?

 

AW AMP was installed in an ESXi 4.1 environment, with 6GB memory, 40GB HDD allocated to it.

 

On my screen shot I do see mention of "Reservation" under MEMORY and CPU sections.  Are you saying I have to configure my AW AMP ESXi host to "reserve" a certain amount of memory?  I have allocated 6GB of memory, but I guess "reserving" means something else?  I would have thought memory usage was like disk usage - a certain amount of space is allocated, and the guest (AW AMP) uses disk and memory as needed, up to the allocated amount?

 

Thanks,

Mike

Hi

 

Reserve nothing but memory which we allocated must to dedicated to airwave instance itself, it should not be used by any other machine which is installed on VM host.

Re: AWave newbie: console showing out of memory errors

At minimum, the smallest install specs should be:

4 core, 8GB RAM, 80GB disk.

 

It needs the RAM to start up the daemons in the right timing, otherwise the initialization scripts that deploy the db and feature templates fails to start.  If you go under the support menu - launch the diagnostics tarball, and then download it - the service_watcher and low_level_service_watcher will show which items are attempting to gather memory needed.

Re: AWave newbie: console showing out of memory errors

Ive never configured a VMware virtual machine by "reserving" resources.  All I ever do is allocate a certain amount of memory and disk space and let VMware take care of the rest.  Do you have any article or FAQ you can share with me that describes exactly how Airwave needs to be configured when running as an ESXi virtual machine?

Re: AWave newbie: console showing out of memory errors

Loading the AirWave install ova observes the specs I provided.  The ISO will only give you the amount of space that was allocated when the VM was initially setup / allocated.

 

If you're manually deploying a VM to use the ISO, assuming VM 6.5 -> here are the steps:

1. Highlight the 'host'

2. Create/Register VM

3. Create a new VM

4. Input name, OS=linux, OS family=Cent 4/5+

5. Choose datastore

6. @ Customize settings: 4 CPU, 8 GB RAM, 80 GB disk (or more), then mount ISO

Re: AWave newbie: console showing out of memory errors

I'll try increasing RAM from 6GB to 8GB and see if the memory errors go away.  I'm monitoring a very small number of devices, probably less than 25 when I'm done.  So I imagine the 80GB is not needed - that's why I picked 40GB.

 

What is the "reservation" that Pavan suggested?  Is there some special reservation process for memory for a given virtual machine in ESXi that I'm supposed to do?  Or was he just suggesting to allocate memory in the properties of the vm?
