I have questions regarding a Magento 2 build with a custom theme, around 2100 products and number of extensions. It has been running for a week or so on 8GB RAM and 8 Cores in a 1&1 Cloud, we have had many ElasticSearch crashes (at least one per day) where we have had to start Elastic Search due to 'No alive nodes found in your cluster', on average we have received 1 order per day during this period, so there is no huge traffic requirement currently.
The hosting environment is is dedicated Plesk Onyx / Ubuntu, 8Core, 8GB, 200GB SSD.
Our developers have suggested increasing the RAM to 20GB to cope with the requirements of MySQL (using 4-5GB currently at peak times), NGinx (using 4GB at peak times) and ElasticSearch (using 3-6GB at peak times).
Is it common for a relatively low traffic site with a couple of thousand products to require this amount of resources?
Could there be other problems with the website build or server configuration that we would should be questioning?
Any advice would be appreciated.
recently we have a similar issue with products (9 lack)
so we tried one third-party server:- https://www.elastic.co/
It is working fine until 2 lack, hope you can try 15 days trial and then after you can change if working fine.
hope it will help you.
If you like then give kudos or mark as solution.
20GB of RAM sounds a bit overkill for your situation.
Are your developers responsible for managing and tweaking/optimizing the server?
If you don't have a server administrator who is familiar with both server management and Magento, you may want to consider hiring one or going with a Magento focused host so they will be able to assist with optimizing the server for your store.
It does sound like overkill for your situation. Do you have SSH access where you can use tools to figure out what exactly is using up all the resources? It really sounds like something is being quite the hog on your MySQL resources. It could be as simple as one of the modules you have installed. Have you tried turning them all off and then turning just one on at a time? However it could also be a combination of a couple of modules.
<< Snipped >>
you have no information about daily sales qty,
please check your stats and total database size,
also ELK stack needs some ram to operate properly.
if you have really low traffic, then your peak usage is very strange.
system needs some review.
