VCPF-70-000019 - Performance Charts must limit the number of allowed connections

Information

Limiting the number of established connections to Performance Charts is a basic denial-of-service protection. Servers where the limit is too high or unlimited could run out of system resources and negatively affect system availability.

Solution

Navigate to and open:

/usr/lib/vmware-perfcharts/tc-instance/conf/server.xml

Configure the <Connector> node with the value:

acceptCount='300'

Restart the service with the following command:

# vmon-cli --restart perfcharts
