Configuring event thresholds (SLAs) for automatically discovered applications

The thresholds determine when the system detects a Minor or Critical event on each transaction entry point: when the system displays the event in the TrueSight console and when notifications are sent.

Before you begin

Before you can configure event thresholds for automatically discovered applications, ensure the following:

• Your environment includes BMC TrueSight App Visibility Manager.
• Set up applications for monitoring and configure application discovery.
• To perform this procedure, you must have Application Administrator-level access.

The following video (2:55) shows you how to configure SLA thresholds for automatically discovered applications or an application with end-user monitoring.

To configure performance and availability event thresholds

1. From the TrueSight console navigation pane, select Configuration > Applications.
2. Click the name of an automatically discovered application, or an application with end-use monitoring, for which you want to adjust the event thresholds.
3. From the Application Configuration action menu, select Edit Application.
4. Click the Transaction tab to set the event thresholds.

5. To modify thresholds for performance, perform the following actions:

   1. For each transaction entry point, set the percentage of transactions with latency issues to trigger events.
   2. Select the severity at which the system sends notification about the event.
   3. Set the latency values for parts of the transaction.

   Performance threshold options

   Option	Description
   Minor Threshold (%)	For each transaction entry point, the percentage of transactions that exceed one or more performance thresholds, which generates a minor event Default value: 5%
   Critical Threshold (%)	For each transaction entry point, the percentage of transactions that exceed one or more performance thresholds, which generates a critical event Default value: 10%
   Send Notification	Determines if notification is sent, and if so, at what event severity: Never When minor or critical threshold is breached (Default) When critical threshold is breached
   E2E Latency (ms)	End-to-end time at which a user transaction is considered slow and users are impacted The E2E latency value must be greater than or equal to the largest latency value of Network, Server, or Database. Default value: 3500 ms
   Network Latency (ms)	(Automatically discovered applications) Network time between the client and server that is considered slow and users are impacted Default value: 500 ms
   Server Latency (ms)	(Automatically discovered applications) Server time, including the web server and application server, that is considered slow Default value: 2000 ms
   Database Latency (ms)	(Automatically discovered applications) Database time that is considered slow Default value: 100 ms

6. To modify thresholds for availability errors, perform the following actions:

   1. For each transaction entry point, set the percentage of transactions with errors to trigger events.
   2. Select the severity at which the system sends notification about the event.
   3. Set the HTTP Status Codes numbers, or number range, for which errors are monitored.

   Availability Errors threshold options

   Option	Description
   Minor Threshold (%)	For each transaction entry point, the percentage of transactions that have errors, which generates a minor event Default value: 5%
   Critical Threshold (%)	For each transaction entry point, the percentage of transactions that have errors, which generates a critical event Default value: 10%
   Send Notification	Determines if notification is sent, and if so, at what event severity: Never When minor or critical threshold is breached (Default) When critical threshold is breached
   HTTP Status Codes	Code numbers for the HTTP errors that you want to monitor Enter number ranges, individual codes, or both, separated by a comma, for example, 400-450,500-550,308 Default: 400-599

7. Click Save.
