How to Configure the Data Collection Frequency

By default, uberAgent collects performance data every 30 seconds. This interval can be changed in the configuration.

Timers

uberAgent can run an unlimited number of independent timers. Each timer wakes up at regular intervals and collects the metrics assigned to it. When a timer has completed a data collection task, it goes back to sleep for the configured length of the timer interval. This means that the time between data collections is the length of the timer interval plus the time it takes to collect the data.

Timer Runtime

In most cases data collection is nearly instantaneous and, therefore, the time between data collections is essentially identical to the timer interval. In some rare cases, e.g., where data is collected from WMI, the data collection may take a noticeable amount of time. In such cases, the time between data collections may be significantly longer than the configured timer interval.

Note: uberAgent’s timers do not guarantee a certain number of data collections per time unit. Do not assume that, for example, a 30 second timer interval yields exactly two events per minute.

Changing the Timer Interval

As mentioned above, data collection happens every 30 seconds by default for most metrics. To change the interval to, e.g., 10 seconds, edit the uberAgent.conf configuration file so that the lines where the intervals are configured read like this:

# interval unit: milliseconds
interval = 10000
 

If, on the other hand, you want to receive only certain metrics at a higher resolution (e.g. 5 seconds), create a new timer section as follows:

[Timer]
Name = High-frequency GPU usage
Comment = Isolate GPU metrics from the other metrics
# interval unit: milliseconds
Interval = 5000
UA metric = GpuUsage
 

With this configuration, uberAgent collects GPU usage data every five seconds. Be sure to remove the GPUUsage metric from any other timers, or it will be collected there as well.

In addition to timers that collect data at time-based intervals, uberAgent also has on-demand metrics that collect data when specific events occur, such as user logins.

Note: Be sure to consider metric dependencies when separating metrics and placing them in individual timers.
