4 CPU
12 GB Memory min 16 GB recommended
60 GB disk minimum.
*********************************************************************
1. OBA collectors server host recommendations                                                             
Number of monitored hosts up to 500 - 1 Collector is require         
     8 CPU                                                             
     24 GB Memory minimum 32 GB recommended                             
    40 GB Disk minimum.                                               
Vertica cluster nodes 1 node (8 CPU, 32 GB Memory, 1 TB Disk)

2. Number of monitored hosts up to 5000 - 3 collectors servers           
    8 CPU
    24 GB Memory minimum 32 GB recommended
    40 GB Disk minimum each
Vertica Cluster nodes 3 node cluster. Each node 16 CPU, 64 GB Memory,10 TB Disk

**********************************************************************
3. Number of monitored hosts more than 5000 - 1 collector is require
 (Add 1 Collector for every additional 5000 nodes)
Same resources require as mentioned above.
Vertica Cluster nodes 3 or more node cluster.Each 32 CPU, 256 GB Memory, 10 TB Disk

*************************************************************************
Note : Certain collection types, like custom metric collections, SiteScope, and NNM/NPS collections may require substantially more disk space in Collectors.

OMi-Sitescope(SIS) integration issue

#As a connected server in OMI 10.62 the connected server is failed.

Goto OMI_install_dir\WebServer\conf\extra\httpd-ssl.conf and alter the following configurtaion

SSLProtocol all -SSLv3 -TLSv1 -TLSv1.1
Change the line as follows:

Operation Bridge Analytics

Overview

OBA (Operations Bridge Analytics) : OBA is an analysis tool that provides a unified approach to proactively manage environment.From search queries using the Phrased Query Language (PQL) to view metric, event.
Identify the server and network performance problems

1. Provides the business logic and presentation capabilities of Operations Bridge Analytics.


2. Deployed as a server installation.


3. Operations Bridge Analytics can have one or more Operations Bridge Analytics Servers depending on the amount of users the system needs to support.


4. The server is JBoss-based.
