Threshold Configuration for Network Attributes

After adding a network monitor, you can track the performance metrics of critical network devices such as routers, switches, and firewalls using SNMP, and visualize, monitor, optimize, and manage the network devices and interfaces.

A Threshold and Availability Profile for a network device helps the alarms engine to send alerts when the resource is critical, down, or in trouble. The alert occurs on any breach of predefined conditions that you set. Additionally, you can also configure thresholds for the following:

• Network Interfaces 
• Bulk Network Interfaces
• Performance Counters
• Bulk Performance Counters

Threshold Configuration for Network Interfaces

1. Log in to your Site24x7 account.
2. Navigate to Network > Network Devices > select a network device > click the Interfaces tab.
3. Click the hamburger icon corresponding to the interface that requires threshold configuration updates.
   
   Figure 1. Select Edit Threshold Profile
4. Click Edit Threshold Profile.
5. Fill in the following fields in the Edit Threshold Profile pop-up. You can set the condition as Critical or Trouble based on which you'll receive alerts for the configured thresholds.
   • Skip Alert: The default selection is No, so you will receive alerts when the threshold value breaches. Toggle to Yes if you wish to skip the alerts.
   • Configure thresholds for the following attributes based on conditions (>,<, =, ≠, >= or <= the value), and be notified when they're breached.
     • In Traffic: Value in bps, Kbps, Mbps, Gbps, or Tbps
     • Rx Utilization: Value in %
     • Out Traffic: Value in bps, Kbps, Mbps, Gbps, or Tbps
     • Tx Utilization: Value in %
     • Error Rate: Value in %
     • Discard Rate: Value in %
   You can set two threshold conditions for each of the above parameters: one for a Trouble alert and another for a Critical alert.
6. Alert when the interface is Down/Trouble: The default selection is No. Select Yes if you wish to change the device status to Trouble or Critical when the interface status changes to Down/Trouble.
   You'll only receive alerts if you select Yes. Alternatively, you can set this value in the Threshold Profile of the device. For this, navigate to Network > Network Devices. > Select a Device. Navigate to the Inventory tab. Click the pencil icon beside Threshold and Availability and toggle to Yes for the Mark the device as Trouble when an interface is Down/Trouble field. You can also select this option in Admin > Configuration Profiles > Threshold and Availability. Click the profile you'd like to edit on this page, and then toggle to Yes in the Mark the device as Trouble when an interface is Down/Trouble field.

Bulk updating Threshold Configurations for Network Interfaces

1. Navigate to Network > Network Devices > select a network device > click the Interfaces tab.
2. Click the Threshold Configuration button.
3. Click the drop-down menu corresponding to Child Monitors in the Bulk Edit Threshold pop-up.
4. Select the desired interfaces for which you wish to update the thresholds in bulk.
5. Follow step 5 (as above) to fill in the required fields

6. Click Save.

Threshold Configuration for Performance Counters

1. Navigate to Network > Network Devices.
2. Click the respective device name.
3. Navigate to the Performance Counters tab on the device dashboard.
4. Hover over the performance counter that requires threshold configuration updates.
5. Click the Edit Threshold Button below the value of the performance counter.

6. Fill in the following fields in the Edit Threshold pop-up. You can set the condition as Critical or Trouble based on which you'll receive alerts for the configured thresholds.
   • Skip Alert: The default selection is No, so you will receive alerts when the threshold value breaches. Select Yes if you wish to skip the alerts.
   • Value: Configure thresholds based on conditions (>,<, =, ≠, >= or <= the value), and be notified when they're breached

3. Navigate to the Performance Counters tab on the device dashboard.
4. Click the Threshold Configuration button.
5. Click the drop-down menu corresponding to Child Monitors in the Bulk Edit Threshold pop-up,
6. Select the desired performance counters for which you wish to update the threshold conditions in bulk.
7. Fill in the following fields in the Bulk Edit Threshold pop-up. You can set the condition as Critical or Trouble based on which you'll receive alerts for the configured thresholds.
   • Skip Alert: The default selection is No, so you will receive alerts when the threshold value breaches. Select Yes if you wish to skip the alerts.
   • Value: Configure thresholds based on conditions (>,<, =, ≠, >= or <= the value), and be notified when they're breached.
   • String Value: Configure thresholds for Performance Counters with string values based on conditions (Equals, Not Equals, Contains or Doesn't Contain the value you specify).
