Configure Merge Groups
You can update the default merge group and you can create custom merge groups.
Update the default merge group
You must use the Graze API to update the default merge group. You cannot update it using the UI. See the following topics for instructions on updating or viewing the details of the default merge group:
getDefaultMergeGroup: Returns details of the default merge group in Moogsoft Onprem.
updateDefaultMergeGroup: Updates the default merge group in Moogsoft Onprem.
Configure custom merge groups
You can configure a custom merge group in the Moogsoft Onprem UI or using the Graze API.
Before you begin
Before you create a custom merge group, ensure you have met the following requirements:
You have configured at least two different clustering algorithms, for example, Cookbook and Tempus.
Your LAMs or integrations are running and Moogsoft Onprem is receiving events.
Configure a custom merge group in the Moogsoft Onprem UI
To configure a custom merge group in the Moogsoft Onprem UI:
Navigate to the Settings tab.
Click Merge Groups in the Algorithms section.
Select an existing custom merge group and click Edit, or click Add Merge Group to add a new one.
Configure the custom merge group settings:
Name: Enter a name for the custom merge group.
Sigaliser: Select the clustering algorithms to include in the custom merge group. To include additional clustering algorithms, click Add Sigaliser.
Similarity Threshold: The percentage of alerts two Situations must share before they are merged. Enter a value between 0 and 100. The default similarity threshold in the default merge group is 70%. Set a lower value if you want Moogsoft Onprem to merge Situations with a lower percentage of alerts shared between them, which is likely to increase the number of Situations that will merge. Set a higher value if you want to decrease the number of Situations that Moogsoft Onprem will merge. If you set this value to 0, Moogsoft Onprem uses the default merge group value.
Click Save to finish configuring the custom merge group.
If you want to change the alert threshold for this custom merge group, use the Graze API endpoint updateMergeGroup.
After you configure a custom merge group, Moogfarmd automatically restarts and begins using it.
Configure a custom merge group using the Graze API
Use the following Graze API endpoints to configure custom merge groups:
addMergeGroup: Adds a new custom merge group.
deleteMergeGroup: Deletes an existing custom merge group.
getMergeGroups: Returns details of all the custom merge groups in Moogsoft Onprem.
updateMergeGroup: Updates a custom merge group.
