After the installation, you will have the following Double-Take Management Pack assets.
- Double-Take Product Version Attribute—This attribute checks the Double-Take product version and is used by the Double-Take Servers computer group.
- Double-Take Servers Group and Installation Type—This asset uses a formula and regular expression match on the Double-Take Product Version attribute to determine which servers have Double-Take installed.
- Double-Take Rules—Rules can be found under the Management Pack Objects section, and contains all of the rules that comprise the Management Pack. Performance Rules, Alert Rules and Event Rules are grouped together under the Rules category. (To see only Double-Take rules, change the scope of the Rules group and filter by Double-Take Servers Installation.)
- Double-Take views—Various views are available as described in Double-Take Specific Views above.
Except for vendor produced product knowledge, all aspects of the Management Pack can be modified by the SCOM administrator. Use the following notes as suggestions for customization, and see your SCOM documentation for complete instructions.
- Threshold configuration—Because each server environment is different, the thresholds at which alerts should be generated will be different. To enable one of the pre-existing (but disabled) performance rules, right-click a performance rule and select Properties. On the General tab, enable Performance Rule. If you want to customize the threshold trigger, modify the threshold value on the Overrides tab.
- Multi-tier alerting—Although only one performance rule is provided for each performance counter, by copying that rule and changing the alert severity and threshold values, multi-tiered alerting is possible. For example, it is possible to generate a warning alert when 1024 MB memory is used for queuing and generate an error when 512 MB is consumed. Threshold values can be modified on the Overrides tab. Alert severities can be modified on the Configuration tab, by highlighting the GenerateAlert entry and editing the XML data behind the rule. For more details, see your SCOM documentation.
- Enable additional event rules—By default, only a pre-selected group of events will generate alerts. If additional alerts are desired, enable additional Event Rules and verify the alert severity.
- Notifications—For each Double-Take Alert Rule, a notification response is pre-selected and will send the applicable message to the defined Recipients and notification Subscriptions. Notification and Subscription options in SCOM do not allow for pre-defined Double-Take notification groups. Therefore, it is required that the SCOM administrator create custom notification Recipients and Subscriptions. (Notification Groups previously used in MOM 2005 can be re-created in SCOM using the Subscriptions feature. For more information on Recipients and Subscriptions, refer to Operations Manager Help using the keyword Notifications.)
