Solution
1 Verify that the collector service is running.
2 If the collector service is not running, check the collector (
vcenter-ops
\user\log\collector.log) and Java
service wrapper (
vcenter-ops
\user\log\collector-wrapper.log) log files.
3 Verify that the network connection is available between the collector and the
vCenter Operations Manager server.
For example, you can try to Telnet from the collector to the vCenter Operations Manager server on the
RMI port that is used for communication, which is 1199 by default.
Controller Is Unable to Connect to MQ
The controller cannot connect to ActiveMQ.
Problem
The message Controller is Unable to Connect to MQ appears in the Reason pane of the Alert Summary page
for the alert.
Cause
The controller cannot connect to ActiveMQ either during or after installation.
Solution
1 If the problem occurs during installation, determine if a port conflict is preventing the service from starting.
a Check the
vcenter-ops
\user\log\activemq-wrapper.log log file for messages that indicate a port
conflict.
b Run the netstat -ano command and look for the process ID that is using ports 1099 and 61616, which
are the ports that ActiveMQ uses.
2 (Optional) If the ActiveMQ service is running, use the jconsole ipaddress:1099 command to determine if
the sendQueue, receiveQueue, and dataQueue queues are running.
NOTE The JConsole tool is part of the Java SDK and is not included with vCenter Operations Manager.
3 (Optional) If the ActiveMQ service is not running, check the sendQueue setting, log files, and memory
allocation.
a Use the jconsole ipaddress:1099 command to determine if a sendQueue ConsumerCount attribute is
greater than one.
A value that is greater than one indicates that the ActiveMQ service is attempting to communicate
with more than one Web service.
b If a ConsumerCount attribute is greater than one, restart the vCenter Operations Manager service.
c Check the
vcenter-ops
\user\log\activemq-wrapper.log log file for a message that indicates the
database behind ActiveMQ is corrupted.
d Check the
vcenter-ops
\user\log\activemq-wrapper.log log file for an out-of-memory error.
e If an out-of-memory error has occurred, increase the memory allocation in
vcenter-
ops
\user\conf\activemq\wrapper.com and restart the ActiveMQ service.
