Description
Monitors the Interface Status, Utilization, Traffic, Errors and Discards Rate. It uses 64-bit counter SNMP OIDs to monitor Traffic and Utilization.
Prerequisites
SNMP should be enabled in end device and device should support IF-MIB.mib OIDs and SNMP credentials should be attached against the device in portal.
How to Apply: While assigning the template, it will show get components discovery button. Once we click on it, it will show values for the following properties: ifAdminStatus ifOperStatus ifAlias User should select whatever properties they want to monitor.
Metric Parameters
| Parameter | Description |
|---|---|
| Frequency | |
| Warning Threshold | If the metric value satisfies the condition defined along with Warning Threshold value, then a notification is sent to the user. |
| Critical Threshold | If the metric value satisfies the condition defined along with Critical Threshold value, then a notification is sent to the user. |
| Alert | The alert value can be set to either Yes or No. If it is Yes, then an alert message is sent to the user. |
