Chapter 1 Monitoring and Troubleshooting Your WAAS Network
Configuring Flow Monitoring
Step 4 Check the Enable check box.
Step 5 In the tcpstat-v1 Host field, enter the IP address of the monitoring agent console.
This configuration allows the WAE to establish a temporary connection (a control connection) to the
console for the purpose of obtaining the IP address of the collector device. You must configure the
collector IP address information from the console device. (See the configuration documentation for the
NetQoS flow monitoring application software.)
Step 6 Click Submit to apply the settings to the devices in this device group.
To configure flow monitoring on the WAE using the CLI, follow these steps:
Step 1 Register the WAE with the IP address of the monitoring agent console.
WAE(config)# flow monitor tcpstat-v1 host 10.1.2.3
This configuration allows the WAE to establish a temporary connection (a control connection) to the
console (or host) for the purpose of obtaining the IP address of the collector device. You must configure
the collector IP address information from the console device. (See the configuration documentation for
the NetQoS flow monitoring application software.)
Step 2 Enable flow monitoring on the WAE appliance.
WAE(config)# flow monitor tcpstat-v1 enable
Step 3 Check the configuration by using the show running-config EXEC command.
Alarms for Flow Monitoring
Table 1-15 describes the four different alarms that may be raised when errors occur with flow
monitoring.
Table 1-15 Alarms for Flow Monitoring
Name Severity Description
CONTROL_CONN Major Indicates a problem with the control connection.
COLLECTOR_CONN Major Indicates a problem with the collector connection.
SUMMARY_COLLECTION Minor Indicates a problem with the collection of packet
summary information.
Summary packets may be dropped because the
buffer queue limit has been reached or because of
a TFO error, such as not being able to allocate
memory.
Summary packet collection may also be
dependent on available WAN bandwidth.
DATA_UPDATE Minor Indicates a problem with the ability of the WAE to
send updates the collector agent.
