- Glossary
Both send and receive queues are stored on disk by default in the <VMware vCenter Server Heartbeat Install
Directory>\R2\log directory, with a quota configured for the maximum permitted queue size (by default, 1GB on
each node).You can configure both the queue location and the quota.
Two methods to set the queue size:
■
Using vCenter Server Heartbeat Console:
1 Start vCenter Server Heartbeat
2 Open the vCenter Server Heartbeat Console, and select Data: Traffic Queues.
3 Click Configure.
4 Configure the Allow a maximum value and click OK.
5 Shut down and restart vCenter Server Heartbeat to effect the change.You are not required to stop protected
applications.
■
Using the Server Configuration wizard:
1 Shut down vCenter Server Heartbeat.
2 Open the Server Configuration wizard and select the Logs tab.
3 Configure the Maximum Disk Usage value and click Finish.
4 Start vCenter Server Heartbeat.
Note vCenter Server Heartbeat is a symmetrical system and can operate with either node in the active role.
For this reason, queue size is always set to the same value for both nodes.
MaxDiskUsage Error Messages
The following error messages display when available disk space on the nodes is exceeded.
[L9]Exceeded the Maximum Disk Usage
(VCChannelExceededMaxDiskUsageException)
This message indicates that you have exceeded the amount of allocated disk space reserved for the queue.
Problem
vCenter Server Heartbeat exceeds its preconfigured queue size.
Cause
On the active node, the size of the send queue has exceeded the disk quota allocated for it. On the passive
node, the size of the receive queue has exceeded the disk quota allocated for it.
Solution
◆
While neither condition is critical, determine the sequence of events that led to the condition.
