The load_avg node describing average CPU usage on the server is presented by complex type load_avgStatType (plesk_server.xsd). The node is structured as follows:

• The l1 node is required. It specifies the average usage of the server CPU (in %) during last minute. Data type: double.
• The l5 node is required. It specifies the average usage of the server CPU (in %) during last 5 minutes. Data type: double.
• The l15 node is required. It specifies the average usage of the server CPU (in %) during last 15 minutes. Data type: double.

The part of the response packet returning CPU usage statistics may look as follows:

<load_avg>
   <l1>10</l1>
   <l5>14</l5>
   <l15>9</l15>
</load_avg>

Here, average server load during the last minute is 10%, last 5 minutes, 14%, and last 15 minutes, 9%.
