4.5 Availability

This Knowledge Script is obsolete, although you can still use it. Its functionality is distributed among the following Knowledge Scripts introduced with AppManager for Exchange Server 2007 version 7.3:

*******************************************************************************************************

Use this Knowledge Script to monitor the availability of the Exchange Server Mailbox Role and Hub Transport Role.

For the Mailbox Role, this script monitors the following activities:

Mailbox database availability
Replication latency
Number of pending replication transactions
Replication rate
Status of replication agent
Availability of the File Share Witness, a requirement for using the CCR functionality in Exchange Server 2007

For the Hub Transport Role, this script monitors the availability of the Transport Dumpster, a container for e-mail that has already been sent and is waiting for deletion.

Event severity when mailbox databases are unmounted	Set the severity level, from 1 to 40, to indicate the importance of an event in which mailbox databases are unmounted. The default is 15.
Replication Latency
Raise event if replication latency exceeds threshold?	Select Yes to raise an event if replication latency exceeds the threshold you set. The default is Yes. When this parameter is set to Yes, the Extended ESE performance counters in the registry are enabled. The following updates are made automatically in the registry values: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ESE\Performance Value Name: Show Advanced Counters Data Type: REG_DWORD Value: 1
Event severity when replication latency threshold exceeded	Set the severity level, from 1 to 40, to indicate the importance of an event in which replication latency exceeds the threshold you set. The default is 5.
Threshold -- Maximum replication latency	Set the maximum number of milliseconds for which replication latency is allowed before an event is raised. The default is 20000 milliseconds.
Pending Replication Transactions
Raise event if pending replication transactions exceed threshold?	Select Yes to raise an event if the number of pending replication transactions exceeds the threshold you set. The default is Yes.
Event severity when pending replication transactions exceeds threshold	Set the severity level, from 1 to 40, to indicate the importance of an event in which the number of pending replication transactions exceeds the threshold you set. The default is 5.
Threshold -- Maximum number of pending replication transactions	Set the maximum number of pending replication transactions allowed before an event is raised. The default is 500.
Replication Rate
Raise event if replication rate exceeds threshold?	Select Yes to raise an event if the replication rate exceeds the threshold you set. The default is Yes.
Event severity when replication rate threshold exceeded	Set the severity level, from 1 to 40, to indicate the importance of an event in which the replication rate exceeds the threshold you set. The default is 5.
Threshold -- Maximum replication rate	Enter the maximum number of replications allowed per minute before an event is raised. The default is 500.
Replication Agent
Raise event if replication agent is not running?	Select Yes to raise an event if the replication agent is not running. The default is Yes.
Event severity when replication agent is not running	Set the severity level, from 1 to 40, to indicate the importance of an event in which the replication agent is not running. The default is 5.
