Analytics VM memory : 9Gb recommended, less than 4Gb used

Hello,

When I installed Vcops, I followed the recommendation for the analytics vm : Si it has 9Gb of memory.

My host is running out of memory so I'm trying to find oversized VM, and with Vcops, I can see that the analytics vm never used more than 4Gb.

I saw in the installation guide that the recommendation was 9Gb for up to 1500 VM to monitor. I have a little infrastructure with less than 70 VM.

I will add some in the futur, but I don't think i'll reach 130 VM before years.

So my question is, would it be reasonable to allocate only 4Gb to this VM ?

Thank you in advance.
