Issue/Introduction

What are the man recommendations to ensure a good performance in an AIOps setup?

Environment

DX OI, APM, AXA 2x on-premise

Resolution

1) Follow Techdocs DX Platfom - Software and Hardware requirements

2) Below are the main aspect that affects performance:

 

a) Actual storage (SSD drive) performance

 

-SSD is recommended.

-Test IO throughput local to ensure storage is fast.

 

b) Network performance.

 

-Ensure a10GBit connectivity.

-You can use iperf3 tool (yum install iperf3) :

On server: iperf3 -s -p 1111

On client: iperf3 -c SERVERIP -p 1111

 

for more details refer to iperf network testing

 

c) CPU on NFS server and Client.

 

-Server or client should not be overloaded and in case of VM it should not be experiencing CPU stealing (overcommit).

-CPU has a big effect on network latencies as kernel schedule work for other processes as well.

 

d) Make sure NFS 4.1 is in-use

 

NFS 4.1 is recommended

See, DX AIOps Installation check - How to verify the NFS version?

 

e) Storage should not be shared

 

-There should no be load during a FIO validation.

-Shared storage will have unpredictable performance results.
