Describes how to use Amazon CloudWatch to operate your system with the smart workload recovery feature.

A.3.1.1 Changing the monitoring target settings

If you want to change the frequency at which metrics and logs are collected, or if you want to add or delete logs to monitor, modify CloudWatch Agent configuration file that you created in "A.2.2.10.2 Configuring CloudWatch Agent". Then start CloudWatch Agent with the configuration file. For more information about CloudWatch Agent configuration files, see "Installing the CloudWatch agent" in the "Amazon CloudWatch User Guide".

A.3.1.2 Operation when RMS startup is stopped / RMS monitoring is disabled

Perform the following procedure when you want to operate (start or stop) RMS that is monitored, for example, when applying RMS corrections.

Preparation

You must first create two files as configuration files for the CloudWatch agent.

1. RMS/log monitoring file

   Configuration files with metrics and logs sections

   Refer to "A.2.2.10.2 Configuring CloudWatch Agent" for the creation method.

2. Log monitoring file

   Configuration files in the logs section only

RMS Operation

     To stop RMS, see "7.1.3 Stopping RMS" in the "PRIMECLUSTER Reliant Monitor Services (RMS) with Wizard Tools Configuration and Administration Guide".

     To start RMS, see "7.1.1 Starting RMS" in the "PRIMECLUSTER Reliant Monitor Services (RMS) with Wizard Tools Configuration and Administration Guide".
