Hi,
I´m getting this problem while loading the Log Server.

If someone could help me about this, would be appreciate.

How much free space and ram are on the machine:

df -h
free -m

Is this an install of the OVA? If so, the default memory allocation(2GB) can be too small and can/should be increased.

This is a free machine from AWS.So maybe is it the free space? or is it the ram?.

Code: Select all

I would start with adding more memory to the machine. The system requirements for Nagios Log Server list 2GB as the minimum.

Posted: **Tue May 08, 2018 10:06 am**

Oh yeah, definitely the RAM. 2GB minimum, but 4GB is what I usually go with to be safe.

Is it valid to do it whit swap? because if not i need to pay for the increase of ram. It´s only for testing if it could fit into my boss enterprise.You know?.

If this is a prototyping machine with incredibly low load, you could probably get away with using swap.

However, Elasticsearch really super duper performs poorly when segments are held in swap. Swap in any sort of production environment will keep ElasticSearch running quite sluggishly if at all.

Network restrictions notwithstanding, rolling a simple lab machine on your local box with the official Nagios Log Server OVF and VirtualBox is probably a better option for reviewing the product.

I definitely have to agree with @mcapra on using your workstation. That way you can allocate more RAM (most likely) without having to have that conversation with your boss.

Ok thank you all for the support the ticket can be close.
