Viewing information about an agent
To view more detailed information about a Data agent, double click an agent
row or click the magnifying glass on an agent row. Information about that agent
appears in the content pane and is divided into three pages:
Performing actions against agents
You can perform a number of administrative actions against the agents
listed under the node. Different actions are available for each agent
depending on its status. To perform actions against an agent:
- Expand Administrative Services > Agents in the navigation
tree.
- Left click the Data node.
- Select an agent by clicking on its row.
- Click any of the following buttons to perform actions against the agent:
- View Log - View the log file for the agent. The log file contains
informational, warning, and error messages for the previous sessions of
the agent. Use the content of the log file to troubleshoot any errors that
might occur during agent startup, processing, or shutdown.
By default, information from the last 5 sessions of the agent appears
in the log window. A session starts when the agent is started and ends
when the agents goes down. You can increase or decrease how many sessions
for the agent are kept in the history by changing the value for the logFilesKept
parameter in the agent.config file.
Log files for an agent and the agent.config file are located in the agent
install directory.
- Configure Tracing - Configure tracing on an agent. The Agent
Tracing Configuration window is displayed.
- Read Config - Have an agent read the agent.config file. The agent.config
file contains parameters that you can change to customize the behavior of
an agent.
Select this option for an agent if you have made changes to the agent.config
file and you want that agent to use those changes.
- Check - Check to: 1) Determine if an agent is up or down, and 2)
determine if the version of the agent is out of date. If the agent needs
to be upgraded, clicking this option will automatically install the required
upgrades.
Note: A Check will also enable an agent that is currently disabled.
- Shutdown... - Shut down this agent. You can choose to shutdown
in the following ways:
- Normal - Shut down the agent software and let all running processes
complete. The agent will continue to accept new jobs that are submitted
and won't shut down until 1) all running processes are complete and
2) there are no new jobs submitted.
- Immediate - Shut down the agent software when the currently running
processes complete. No new jobs will be accepted by the agent and shutdown
will occur immediately after the last job completes.
- Abort - Shut down the agent software and stop whatever processes are
currently running.
- Disable - Select this option to designate that an agent is "unavailable"
and to indicate that the server should not contact the agent for any job
processing. Use this option depending on the situation within your environment.
For example, you might want to disable an agent when:
- the agent machine is undergoing maintenance and will be unavailable.
This prevents the server from flagging the agent as "down"
if it cannot reach the agent a certain amount of times as defined by
the agentErrorLimit parameter in the server.config file.
- the agent machine is busy with resource-intensive processing and you
want do not want to add any Data Manager jobs to that processing load.
While disabled, the agent will appear with a red outlined circle with
a line through it in the user interface and the server will not attempt
to contact the agent.
- Enable - Select this option to re-enable an agent that is currently
disabled. Once enabled, the server will resume communication with the agent.
Note: If the server cannot contact an agent equal to the number defined
for the agentErrorLimit parameter in the server.config (the default is 3),
the server will automatically flag the agent as "down". Select
the this option to reestablish communication between the agent and server
and reset the agentErrorLimit parameter to 0.
Note: A Check action will also enable an agent that is currently disabled.
- Delete - Erase the agent from the database repository.
