How to configure my Data Collector to make use of new resources.

Products

• CA Infrastructure Management
• CA Performance Management - Usage and Administration
• DX NetOps

Issue/Introduction

When installing DX Netops Performance Management components, memory usage is set by a combination of questions and automatic evaluation of the system resources.

If you increase memory on the host, you need to manually edit some files for DX Netops Performance Management to make use of these new resources.

 

Environment

DX NetOps Data Collector: All Supported Releases

Cause

Formula for memory allocation:

80% for the DC (Data Collector)

1000m (1g) for AMQ (Active MQ (data broker))

 

There will be 2 files to edit for the DC:

/opt/IMDataCollector/apache-karaf/bin/setenv - this is for runtime values.

/opt/DCM.cfg - this is for re-installs and upgrades to inherit current values.

 

Memory for AMQ is managed in:

/opt/IMDataCollector/scripts/activemq

Do not edit unless support Tells you to do so.

Resolution

For the DC memory settings edit these files:

(this is the default path, your environment may vary)

/opt/IMDataCollector/apache-karaf/bin/setenv

 

Find and edit this line:

export IM_MAX_MEM=9566M

 

/opt/DCM.cfg

 

Find and edit this line:

IM_MAX_MEM=11755M

 

stop the data collector process:

   systemctl stop dcmd

stop the activemq process:

   systemctl stop activemq

start Data Collector:

systemctl start dcmd

This will automatically restart activemq
