6.1.1 Predictive error detection in the performance of a monitored service

Tasks in SLM

While the monitoring staff was monitoring the status of the monitored services in the Home window, a warning constituting a warning sign of a service performance error was displayed.

The following figure shows a display example of the Home window when a warning is displayed for a monitored service.

Figure 6‒1: Display example of the Home window that contains a warning for a monitored service

Details of the warning displayed in this figure are as follows:

• When detected: 2020-02-05 06:41:03

• Type: OUTLIER

• Details: UPPER LIMIT

• Service group: Group02

• Service: Service02

• Monitored target: All Web Access

• Monitor item: Avg. response

This warning indicates that the average response time of Service02 belonging to Group02 that was obtained at 06:41:03 on February 5, 2020, constituted an out-of-range value (a value exceeding the upper limit) and differed significantly from the usual value for the monitored service.

Results of the task

Because the warning might lead to an error if left unattended, the monitoring staff decided to take corrective action immediately.
