Configure ICMP traffic

To support availability monitoring of IPv4 hosts with the icmp datasource, your Zenoss Data Monitor host must be configured to allow ICMP traffic from userland services.

Prerequisites

• Zenoss Data Monitor is installed and running
• The icmp datasource is configured with at least one monitoring target

Procedure

Follow these steps:

1. Log in to the Zenoss Data Monitor host.

2. Check the security setting.

   sudo sysctl net.ipv4.ping_group_range
   

   • If the result is net.ipv4.ping_group_range = 1 2147483647, stop. Your host is configured to allow ICMP traffic from userland services.
   • If the result is net.ipv4.ping_group_range = 1 0, perform the following step.

3. Enable outgoing ICMP traffic.

   sudo sysctl -w net.ipv4.ping_group_range="0 2147483647"
