Create a Monitor
A Monitor is a set of verifications that are performed by one or more Test Agents for an infinite amount of time. A Monitor contains a single step with one or more parallel Tasks, which continuously monitors the KPIs that you have defined in the Monitor. A Task contains the configuration to measure specific metrics. Monitors measure the metrics indefinitely until you decide to stop the Monitor. For more information on Monitors, see Tests and Monitors Overview.

TTL prevents infinite loop in a network when the packet fails to reach the destination. For example, if you have entered the TTL value as 64, every time the packet passes a device, the value is reduced by one until the packet reaches the remote server. If the entered value reaches zero before reaching the remote endpoint, the packet is discarded. Default value—64 Range—1 through 255 |
| Request Lifetime |
Specify the request lifetime value. Request lifetime value is the maximum duration for which a ping request is alive. It determines how long a request persists before it is counted as lost. Unit—Milliseconds (ms) Default value—2000 ms Range—1 ms through 30000 ms |
| DSCP/IPP |
Specify the Differentiated Services Code Point (DSCP) or the IP Precedence (IPP) value that is used in the IP packet headers. The IPP is the three-bit binary values (Precedence) in the ToS field of the IP header. An IPP value can be in the 0-7 range. IPP value informs the router about the priority of the packet. The higher the IPP value, the more the priority of the packet. See RFC 791 for more information. DSCP is a six-bit binary value in the DS field of the IP header. DSCP value facilitates QoS for traffic management through the Best Effort, Assured Forwarding, Class Selector, and the Expedited Forwarding categories. See RFC 2474 for more information. Default value—0 Range—0 through 255 |

Specify the size of the data portion of the request packets sent from the router. Default value—0. Range—0 through 65400. |
| Data fill |
Specify the contents of the data portion of the request packets sent from the router. The value should be in hexadecimal format. The value should be in hexadecimal format. |
| TTL |
Specify the number of times the packets hop before a device discards the packet. Time to live (TTL) value indicates lifespan of a request packet. TTL prevents infinite loop in a network when the packet fails to reach the destination. For example, if you have entered the TTL value as 64, every time the packet passes a device, the value is reduced by one until the packet reaches the remote server. If the entered value reaches zero before reaching the remote endpoint, the packet is discarded. Default value—64. Range—1 through 254. |
| DSCP Code Points |
Specify the Differentiated Services Code Point (DSCP) value that is used in the IP packet headers. Maximum length—64 characters. |
| Hardware Timestamp |
Enable hardware timestamping of RPM probe messages in the Packet Forwarding Engine host processor on the router. By default, the toggle button is disabled. |
| Ping Timestamp |
Enable ping timestamping to send UDP timestamp requests. By default, the toggle button is disabled. |
| One Way Hardware Timestamp |
Enable the one-way hardware timestamping for one-way delay and jitter measurements. By default, the toggle button is disabled. |
| IPv6 Local Link |
Specify the router link-local logical interface name for the egress interface to be used. This applies only for Test sessions with IPv6 address as the target address. Maximum length—64 characters. |

Field |
Select the type of metric that you want to evaluate from the drop-down list. The metrics listed in this drop-down depends on the Task you select. The metrics will be displayed as Stream graphs in the Stream-Name Details page. |
| Comparator |
Select the type of comparator that you want to use for the evaluation. You can choose among the following comparators—==(equal to), != (not equal to), < (less than), <= (less than or equal to), > (greater than), >= (greater than or equal to). For example, if you have used > (greater than) comparator, and if you have specified 3000 ms in the Value text box, then an event is raised if the value exceeds 3000 ms. |
| Value |
Specify the threshold value that you want to evaluate. On violation of any configured threshold value, an event is generated. |
| Severity |
Select the severity level of the event that is raised when there is a threshold violation. The severity levels are: Debug—Indicates that the event needs troubleshooting. Info—Indicates that it is an informational event and does not require immediate attention. Warning—Indicates that the event needs to be reviewed but does not require immediate attention. Error—Indicates that the event needs to be reviewed and requires immediate attention. Critical—Indicates that the event is major and needs immediate attention. When an event is raised, the severity level you have selected will be displayed in the Events bar of the Monitor-Name page. |
|
Name |
Specify the name for the evaluation criteria. |
|
Description |
Specify the description to be displayed when there is a threshold violation. If you do not specify the description, the default description generated by Paragon Automation is displayed. When an event is raised, the description you have specified here will be displayed in the Events bar of the Monitor-Name page. |
|
Raise Delay |
Specify the duration that the Paragon Automation waits before triggering an event. If the number of seconds exceeds the configured Raise delay value, then an event is triggered. The triggered event is displayed in the Events bar of the Monitor-Name page. |
|
Clear Delay |
Specify the duration of time after which an event is cleared if the threshold is not violated. If the threshold has not exceeded the configured Clear delay seconds, then the event is cleared. |
