2.3.2 Resource collection

By using SSO, you can collect system resources from servers by installing an SNMP agent (ESA) on monitored servers. If you configure the time zone, interval, and period, you can collect resources at regular intervals, and view them.

(1) About resource collection

Resource collection is a process for collecting system resources from the servers connected to a network and monitoring target resources that users arbitrarily configured.

With SSO, you can collect the user resources (resources that can be uniquely defined by a user) and system resources (performance information, statistical information, and operating information) of the network devices and various server products that are supported on the OS (Windows or Linux) and SNMP, and monitor the resources in real time. For example, you can perform monitoring by which an incident is issued when CPU usage exceeds 90%. In addition to issuing incidents, any action can be executed automatically.

You can use SSO to collect the following resources:

Resources related to CPU: CPU Utilization, Run Queue Length, System Calls, etc.
Resources related to memory: Memory Utilization, Swap Utilization, etc.
Resources related to file systems: File System Utilization, File System Available, etc.
Resources related to networks: Interface Utilization, Interface Traffic, etc.

You can easily configure resources to be collected by selecting resources from those displayed in the GUI because resource candidates are registered in advance in SSO. You can also automate the operation because collection can be started and ended by using the command.

Tip

In the resource collection functionality of SSO, a substance of the source from which a resource is collected is defined as an instance, the smallest unit of resources that can be obtained from SNMP agents is defined as a subresource, and a group of multiple subresources is defined as a resource.

Note

You can create a report for any period such as month or hour, by using collected resources. You can check the operating trend of servers by checking the reports, and can create system operation plans more easily. You can output reports in CSV or HTML format. You can output a report that best suits your purpose because you can select various graph formats.

(2) Starting resource collection

In this procedure, you configure the settings to collect resources by using SSO, and start resource collection.

Procedure

In the SSO console, click Resource Configuration.
Click Edit and then Add Collection Condition.
Select a monitored server, and then click Next.
Directly specify a server in New Server, or select a registered server in Registered Server.
Select whether to automatically determine the agent type of the monitored server, and then click Next.
Resources that can be collected differ depending on the agent type. Selecting Yes in the Add Collection Condition (2/3) wizard displays only the resources that can be collected for the agent type in the Add Collection Condition (3/3) wizard.
From Do not Collect, select the resources that you want to collect, and then click Add.
The selected resources are added to Collect.
Click Complete.
Resources to be collected are configured.
Select the resource for which you want to set the collection conditions, and then click Edit and then Change Collection Detail Condition. Select the instance, subresource, and collection mode.
If you do not set the collection conditions, all instances are subject to collection. For the collection mode, you can set whether to save the collected data and whether to monitor thresholds. To monitor thresholds, you also need to set the thresholds and commands that are executed when the thresholds are exceeded.
Click OK.
Resource collection conditions are configured.
Click Edit and then Set Collection Time Zone.
Configure the resource collection time zone if you want to collect resources in a fixed time zone every day.
Select the check box for the number in which you want to specify a time zone, and specify the start and stop times.
For example, to collect resources during the period between 8:00 and 18:00, specify 08:00:00 for the start time, and 18:00:00 for the stop time.
Click OK.
The resource collection time zone is configured.
Tip
You can also configure collection intervals to suit your purpose. By configuring collection intervals, you can reduce the load on the system. To configure collection intervals, click Edit and then Change Collection Interval.
- To detect a sharp rise in the used amount or usage rate of resources, configure a short collection interval.
- To monitor the resource usage for a long period, configure a long collection interval.
From the Actions menu, click Start Collection.
Configure the period of time for collecting resources in Start Collection and Stop Collection fields, and then click Start.
Resource collection is started.

If you have configured the collection time zone, make sure that the time zone is within the period from the start to the stop of collection specified in the Start Collection window.
Note
- To manually stop resource collection, from the Resource Configuration window, select the resource that you want to stop collecting, and then from the Actions menu, click Stop Collection.
- To check the status of resource collection, check the collection status in the Resource Configuration window. The current collection status is displayed by Deferred, Collecting, Completed, etc.

Result

Now resource collection has successfully started. You can start monitoring resources, such as by viewing collected resources and outputting the resources to a report.

Next steps

In the next section, configure the settings to monitor processes and services by using SSO.
