Real-Time Performance Monitoring Services Overview
Real-Time Performance Monitoring (RPM) enables you to configure active probes to track and monitor traffic. Probes collect packets per destination and per application, including PING Internet Control Message Protocol (ICMP) packets, User Datagram Protocol and Transmission Control Protocol (UDP/TCP) packets with user-configured ports, user-configured Differentiated Services code point (DSCP) type-of-service (ToS) packets, and Hypertext Transfer Protocol (HTTP) packets. RPM provides Management Information Base (MIB) support with extensions for RFC 2925, Definitions of Managed Objects for Remote Ping, Traceroute, and Lookup Operations.
You can also configure RPM services to determine automatically whether a path exists between a host router and its configured BGP neighbors. You can view the results of the discovery using an SNMP client. Results are stored in pingResultsTable, jnxPingResultsTable, jnxPingProbeHistoryTable, and pingProbeHistoryTable.
Probe configuration and probe results are supported by the command-line interface (CLI) and SNMP.
The following probe types are supported with DSCP marking:
- ICMP echo
- ICMP timestamp
- HTTP get (not available for BGP RPM services)
- UDP echo
- TCP connection
- UDP timestamp
With probes, you can monitor the following:
- Minimum round-trip time
- Maximum round-trip time
- Average round-trip time
- Standard deviation of the round-trip time
- Jitter of the round-trip time—The difference between the minimum and maximum round-trip time
One-way measurements for ICMP timestamp probes include the following:
- Minimum, maximum, standard deviation, and jitter measurements for egress and ingress times
- Number of probes sent
- Number of probe responses received
- Percentage of lost probes
 | Note: Timestamping is not supported on PTX Series Packet Transport Routers. |
You can configure the following RPM thresholds:
- Round-trip time
- Ingress/egress delay
- Standard deviation
- Jitter
- Successive lost probes
- Total lost probes (per test)
Support is also implemented for user-configured CoS classifiers and for prioritization of RPM packets over regular data packets received on an input interface.
