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.
This topic presents the following sections:
Before you can configure event thresholds for automatically discovered applications, ensure the following:
The following video (2:55) shows you how to configure SLA thresholds for automatically discovered applications or an application with end-user monitoring.
Note
The video demonstrates version 10.5 and also applies to the current version.
To modify thresholds for performance, perform the following actions:
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:
|
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 that is considered slow and users are impacted Default value: 500 ms |
Server Latency (ms) | (Automatically discovered applications) Server time that is considered slow Default value: 2000 ms |
Database Latency (ms) | (Automatically discovered applications) Database time that is considered slow Default value: 100 ms |
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:
|
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, Default: 400-599 |
Click Save.
When your application setup and configuration is complete, you are ready to start Monitoring applications.
