Class OSAgent

java.lang.Object

org.miloss.fgsms.osagent.OSAgent

public class OSAgent
extends Object

fgsms's Operating System agent Provides monitoring and some SLA processing for the machine as a whole or processes running on a machine. Uses the SIGARS API provided by VMWare


FAQ: How to change the reporting rate of os (machine and process monitor) agents?
OS Agents use two different timers.

1. 1) update the running process list, hardware and network information. This is referred to as the refresh rate.
2. 2) update the current status and performnace data. This is referred to as the Reporting Frequency.

The RF is changed via the global configuration setting, Agents.Process, ReportingFrequency.

However, changes with this value are by default updated

• when the agent starts
• once an hour

Since 6.2.1. To increase the rate, a command line option can be added to the os agent's startup script with overrides the default refresh rate to whatever you want, measured in ms. This will generate slightly more load on the machine hosting the agent, and will add additional bandwidth consumption if it is turned down from the defaults. Use the following option -DrefreshRateOverride=(some duration in milliseconds) Since 6.3, OS Agents can now report sensor data back to fgsms. To configure a sensor data feed, a properties file must be provided. Either place sensor.properties in the current working directory or use -DsensorProviders=path to provide the configuration.

The properties file needs only a single setting, sensorProviders with a value equal to a comma delimited list of classes that implement the ISensorProvider interface.
