2.3 Agent

Agents collect performance information by periodically issuing commands or APIs provided by the operating system or middleware.

The information collected by Agents is transformed into monitor data and resource data and sent to a Manager.

Monitor data is summarized data for gaining a general understanding of the state of the system. For example, this data is used when user data is managed.

Resource data is detailed data that is collected for each resource. For example, the disk space usage rate falls into this category. Resource data is further processed into three types of data (for different display objectives) and sent to the Manager.

The rest of this section explains the roles of the directories that are used when Agents run.

DsaFowarder/DsaFowarder_sum directory

This directory is for temporarily storing the data that will be sent to the Manager.

If communications with the Manager are broken, data will be stored in this directory until communications recommence.

If the communications interruption continues for a long time, unsent data will place pressure on the disk capacity. As the amount of available disk space decreases, first a warning event will be output, then an error event, and finally the Agent will stop running.

The specific location for this directory is as follows:

Variable file directory\transfer\DsaForwarder

Variable file directory\transfer\DsaForwarder_sum

/var/opt/FJSVssqc/temp/DsaForwarder

/var/opt/FJSVssqc/temp/DsaForwarder_sum
