Merged services
Settings > Merged service monitoring is deprecated.
- If merged services exist in your environment, you can still access the page to view and edit them.
- You can't create new merged services from this setting page. To create or edit the equivalent of a merged service via rule-based detection, see Create a rule to aggregate services below.
A merged service is a service that aggregates multiple web-request services of the same process group that perform identical functions across separate cluster nodes. These web-request services are effectively identical from a performance-monitoring perspective. A merged service appears in Dynatrace as a single service that contains all the data of all aggregated services.
Say you have an Apache web server with several virtual host definitions (for example, dynatrace.com, dynatrace.at, and dynatrace.pl). From the Apache perspective, these are independent virtual hosts. Dynatrace therefore detects them as separate services. For your monitoring purposes however, you might want to view these services as a single merged service called Dynatrace web page.
Dynatrace automatically identifies mergeable services for you and displays them on the Merged service monitoring page (Settings > Server-side service monitoring > Merged service monitoring). Only services included in this list can be merged.
Characteristics of existing merged services
- Once merged, the data of individual merged services can no longer be distinguished—monitoring data is available only in aggregate form for all the merged services.
- The original services of a merged service are no longer updated as data sources. While historical data remains available (for example, for charting), no new data is tracked for the original services. The aggregated data is assigned to and associated with the merged service.
- Merged services are of the same type. For example, they belong to the same process group, share the same underlying technology, or follow the same naming pattern. Multiple virtual hosts, context roots, or listen ports that represent the same logical entity can be part of a service merging.
- Only near-identical, standalone web-request services of the same process group are merged—merged services are not merged into other merged services.
Split merged services
When you split a service from a merged service ("unmerge" the service), the historic data will be available only for the merged service. All newly captured data will be associated with the new standalone service.
To split a service from a merged service
- Go to Settings > Server-side service monitoring > Merged service monitoring.
- Select Edit
in the row of the merged service you want to split. - Select Remove
in the row of the service you want to remove. - Select Update.
Delete merged service
If you delete a merged service, all individual merged services will be split and once again treated as standalone services.
To delete a merged service:
- Go to Settings > Server-side service monitoring > Merged service monitoring.
- Select Delete in the row of the merged service you want to delete.
Create a rule to aggregate services
To carry out the equivalent task of creating a merged service, but via rule-based service detection
- Go to Settings > Service Detection.
- Select Full web request rules if the web requests are fully monitored by Dynatrace.
- Select External web request rules for web requests going to external resources.
- Select Add item and add a name for your new rule.
- Turn on at least one service identifier contributor from the following: Application identifier, URL context root, and Server name.
- optional You can modify your rule by:
- Setting a management zone
- Adding specific conditions
- Disabling the port
- Select Save changes.
