Checking connection with Manager

Before you check the agent’s connection with the manager, first ensure the agent is pointing to the manager’s IP address. This is set in ossec.conf using the <client> XML tag. For more on this, see Client reference.

<ossec_config>
  <client>
    <server>
      <address>10.0.0.10</address>
      <protocol>udp</protocol>
    </server>
  </client>
</ossec_config>

This will set 10.0.0.10 as the Wazuh Manager server. Once this is done, you will need restart the Agent:

  1. For Systemd:
# systemctl restart wazuh-agent
  1. For SysV Init:
# service wazuh-agent restart

After you register the agent and it has successfully connected, you can see a list of agents that are connected to the manager with:

# /var/ossec/bin/agent_control -lc

You can also check to see if an agent connected correctly by verifying if the UDP connection to the manager is established:

# netstat -vatunp|grep ossec-agentd

The result should match the agent and manager IP addresses.

In the agent_control section, you can find information about the status of the agents that are registered with the manager.
