Notifications about the maximum allowed CPU and RAM load for the Central Node and Sensor servers

Maintaining a high load on the CPU and RAM of the Central Node and Sensor servers may result in the inoperability of the program components.

You can configure maximum values for the CPU and RAM loads on Central Node and Sensor servers; if these are exceeded, the upper part of the Dashboard section of the program web interface for users with the Senior security officer, Security officer, Administrator, or Local administrator roles displays a yellow box with a warning. You can also configure notifications to be sent to one or more email addresses and an SNMP protocol connection for sending information about the CPU and RAM load to external systems that support this protocol.

If you have deployed the Central Node and Sensor components as a cluster, warnings are displayed separately for each server in the cluster.

Users with the Senior security officer or Security officer role can also create rules for sending notifications. In this case, sending notifications correctly requires configuring maximum allowed load values for the CPU and RAM of servers, as well as notification settings on the server.

In existing rules for sending notifications about the program components, the CPU load and RAM load notifications are enabled automatically if the All check box is selected under Components when the rule is created.

Configuring the maximum allowable CPU and RAM load of the Central Node and Sensor servers

In the distributed solution and multitenancy mode, you need to set the maximum allowed load values for the CPU and RAM load of each Central Node server from which you want to receive notifications. If you use a Central Node cluster, you can configure these settings on any cluster server.

To configure the maximum allowed load on the CPU and RAM of the Central Node and Sensor servers:

1. In the window of the program web interface, select the Settings section, General settings subsection.
2. Under Monitoring:
   • In the Warning of CPU usage above N % for M minutes field, enter the maximum allowed CPU usage and time period for which the maximum load can be maintained.

     By default, the maximum CPU load is 95% for 5 minutes.

   • In the Warning of RAM usage above N % for M minutes field, enter the maximum allowed RAM usage and time period for which the maximum usage can be maintained.

     By default, the maximum RAM usage is 95% for 5 minutes.

3. Click Apply.

The maximum allowed load of server CPU and RAM will be configured. If one of the values is exceeded on the Central Node and/or Sensor server, in the upper part of the Dashboard section of the program web interface for users with Senior security officer, Security officer, Administrator, or Local administrator role, a yellow warning box is displayed.
