RPM Configuration Options
You can configure real-time performance monitoring (RPM) parameters. See Table 1 for a summary of the configuration options.
Table 1: RPM Configuration Summary
Field | Function | Your Action |
|---|---|---|
| Performance Probe Owners | ||
Owner Name (required) | Identifies an RPM owner for which one or more RPM tests are configured. In most implementations, the owner name identifies a network on which a set of tests is being run (a particular customer, for example). | Type the name of the RPM owner. |
| Identification | ||
Test name (required) | Uniquely identifies the RPM test | Type the name of the RPM test. |
Target (Address or URL) (required) | IP address or URL of probe target | Type the IP address, in dotted decimal notation, or the URL of the probe target. If the target is a URL, type a fully formed URL that includes http://. |
Source Address | Explicitly configured IP address to be used as the probe source address | Type the source address to be used for the probe. If the source IP address is not one of the device's assigned addresses, the packet uses the outgoing interface's address as its source. |
Routing Instance | Particular routing instance over which the probe is sent | Type the routing instance name. The routing instance applies only to probes of type icmp and icmp-timestamp. The default routing instance is inet.0. |
History Size | Number of probe results saved in the probe history | Type a number between 0 and 255. The default history size is 50 probes. |
| Request Information | ||
Probe Type (required) | Specifies the type of probe to send as part of the test. | Select the desired probe type from the list:
|
Interval | Sets the wait time (in seconds) between each probe transmission | Type a number between 1 and 255 (seconds). |
Test Interval (required) | Sets the wait time (in seconds) between tests. | Type a number between 0 and 86400 (seconds). |
Probe Count | Sets the total number of probes to be sent for each test. | Type a number between 1 and 15. |
Destination Port | Specifies the TCP or UDP port to which probes are sent. To use TCP or UDP probes, you must configure the remote server as a probe receiver. Both the probe server and the remote server must be Juniper Networks devices configured to receive and transmit RPM probes on the same TCP or UDP port. | Type the number 7—a standard TCP or UDP port number—or a port number from 49152 through 65535. |
DSCP Bits | Specifies the Differentiated Services code point (DSCP) bits. This value must be a valid 6–bit pattern. The default is 000000. | Type a valid 6–bit pattern. |
Data Size | Specifies the size of the data portion of the ICMP probes. | Type a size (in bytes) between 0 and 65507. |
Data Fill | Specifies the contents of the data portion of the ICMP probes. | Type a hexadecimal value between 1 and 800h to use as the contents of the ICMP probe data. |
Hardware Timestamp | Enables timestamping of RPM probe messages. You can timestamp the following RPM probes to improve the measurement of latency or jitter:
| To enable timestamping, select the check box. |
| Maximum Probe Thresholds | ||
Successive Lost Probes | Sets the total number of probes that must be lost successively to trigger a probe failure and generate a system log message. | Type a number between 0 and 15. |
Lost Probes | Sets the total number of probes that must be lost to trigger a probe failure and generate a system log message. | Type a number between 0 and 15. |
Round Trip Time | Sets the total round-trip time (in microseconds), from the device to the remote server, that triggers a probe failure and generates a system log message. | Type a number between 0 and 60,000,000 (microseconds). |
Jitter | Sets the total jitter (in microseconds), for a test, that triggers a probe failure and generates a system log message. | Type a number between 0 and 60,000,000 (microseconds). |
Standard Deviation | Sets the maximum allowable standard deviation (in microseconds) for a test, which, if exceeded, triggers a probe failure and generates a system log message. | Type a number between 0 and 60,000,000 (microseconds). |
Egress Time | Sets the total one-way time (in microseconds), from the device to the remote server, that triggers a probe failure and generates a system log message. | Type a number between 0 and 60,000,000 (microseconds). |
Ingress Time | Sets the total one-way time (in microseconds), from the remote server to the device, that triggers a probe failure and generates a system log message. | Type a number between 0 and 60,000,000 (microseconds) |
Jitter Egress Time | Sets the total outbound-time jitter (in microseconds), for a test, that triggers a probe failure and generates a system log message. | Type a number between 0 and 60,000,000 (microseconds) |
Jitter Ingress Time | Sets the total inbound-time jitter (in microseconds), for a test, that triggers a probe failure and generates a system log message. | Type a number between 0 and 60,000,000 (microseconds). |
Egress Standard Deviation | Sets the maximum allowable standard deviation of outbound times (in microseconds) for a test, which, if exceeded, triggers a probe failure and generates a system log message. | Type a number between 0 and 60,000,000 (microseconds). |
Ingress Standard Deviation | Sets the maximum allowable standard deviation of inbound times (in microseconds) for a test, which, if exceeded, triggers a probe failure and generates a system log message. | Type a number between 0 and 60,000,000 (microseconds). |
| Traps | ||
Egress Jitter Exceeded | Generates SNMP traps when the threshold for jitter in outbound time is exceeded. |
|
Egress Standard Deviation Exceeded | Generates SNMP traps when the threshold for standard deviation in outbound times is exceeded. |
|
Egress Time Exceeded | Generates SNMP traps when the threshold for maximum outbound time is exceeded. |
