# SNMP

`rvtrace` embeds an SNMP agent. You can use SNMP applications to query `rvtrace` statistics and trap SNMP events (as listed in SNMP Objects in rvtrace).

SNMP Objects in rvtrace

Object Name | Description
Network Totals
`rvNetTotals` | Grouping for all network totals.
`rvTrdpMCPktTotals` | Grouping for network totals related to multicast data packets.
`rvTrdpMCDataPktTotal` | Total multicast or broadcast data packets.
`rvTrdpMCDataByteTotal` | Total payload bytes in all multicast or broadcast data packets.
`rvTrdpMCRtPktTotal` | Total multicast or broadcast retransmission packets.
`rvTrdpMCRtByteTotal` | Total payload bytes in all multicast or broadcast retransmit packets.
`rvTrdpMCNullPktTotal` | Total null packets. When a Rendezvous daemon has no data packets to transmit, it periodically sends null packets to maintain continuity.
`rvTrdpMCSeqGapTotal` | Total Rendezvous packets that `rvtrace` missed. `rvtrace` tracks the serial numbers of Rendezvous packets. This object counts the missing packets in each sequence gap of multicast or broadcast data packets. For more information, see Gaps Diagnoses.
`rvTrdpMCBadPktTotal` | Total bad multicast data packets. Bad packets lack UDP checksums, or are corrupt in some other way. Warning See Bad Packets.
`rvTrdpRtPktTotals` | Grouping for network totals related to retransmitted multicast or broadcast packets.
`rvTrdpRtReqPktTotal` | Total retransmission request packets. Each request packet counts separately, even if several request packets specify the same data packet numbers for retransmission. For example, if two daemons each request retransmission of the data packets numbered 121–125, and a third daemon requests retransmission of the data packets numbered 100–144, then this total increases by 3.
`rvTrdpRtReqSeqTotal` | Total of requested sequence numbers summed over all retransmission requests. Each retransmission request packet can solicit one or more data packets for retransmission. This object sums the number of data packets for which retransmission is requested. If some data packets are requested several times, each data packet counts separately each time it is requested. For example, if three daemons request retransmission of data packets numbered 121–125, then this total increases by 15. For more information, see Diagnoses.
`rvTrdpRtRejPktTotal` | Total retransmission rejections. Although Rendezvous daemons comply with retransmission requests whenever possible, sometimes the requested packets are no longer available. This object counts the number of packets that contain retransmission rejections.
`rvTrdpRtBadPktTotal` | Total bad multicast retransmission packets. Bad packets lack UDP checksums, or are corrupt in some other way. Warning See Bad Packets.
`rvPtpPktTotals` | Grouping for network totals related to point-to-point packets.
`rvPtpDataPktTotal` | Total point-to-point data packets.
`rvPtpDataByteTotal` | Total payload bytes in all point-to-point data packets.
`rvPtpAckRPktTotal` | Total acknowledgement request packets. Sending Rendezvous daemons explicitly request positive acknowledgment for groups of point-to-point data packets. This object counts the number of packets containing acknowledgment requests for point-to-point data packets.
`rvPtpAckPktTotal` | Total acknowledgement packets. Receiving Rendezvous daemons explicitly acknowledge groups of point-to-point data packets upon request from sending daemons. This object counts the number of packets containing acknowledgments for point-to-point data packets.
`rvPtpNakPktTotal` | Total negative acknowledgement packets. Receiving Rendezvous daemons use negative acknowledgments (`NAK`s) to request retransmission of missing data point-to-point packets. This column displays the number of packets containing retransmission requests for point-to-point data packets. For more information, see Nak Diagnoses.
`rvPtpBadPktTotal` | Total bad point-to-point packets. Bad packets lack UDP checksums, or are corrupt in some other way. Warning See Bad Packets.
`rvSubjectTotals` | Grouping for network totals related to Rendezvous subjects.
`rvSubjMsgTotal` | Total number of messages (summed over all subjects).
`rvSubjByteTotal` | Total number of payload bytes (summed over all subjects).
Thresholds
`rvTrdpRtThreshold` | Threshold for retransmit trap. When the ratio rvTrdpMCRtByteTotal/rvTrdpMCDataByteTotal exceeds this threshold (expressed as a percentage), `rvtrace` sets the SNMP trap rvTrdpNotifyRetransmit. The default threshold is 2%.
`rvBadPktThreshold` | Threshold for bad packet trap. When the number of bad packets during an interval exceeds this threshold, `rvtrace` sets the SNMP trap rvNotifyBadPkts. Bad packets of any type count toward this threshold. The default threshold is zero—that is, trap even for one bad packet.
Multicast Host Snapshot
`rvTrdpMCHostTable` | Table of multicast statistics, with one entry for each triple of sending host (rvTrdpMCHostAddr), service port (rvTrdpMCPort), and destination address (rvTrdpMCDestAddr).
`rvTrdpMCPort` | Service port of packets counted in the table entry.
`rvTrdpMCHostAddr` | IP address of the host that is the source of multicast or broadcast packets counted in the table entry.
`rvTrdpMCDestAddr` | Destination address of packets counted in the table entry. The destination can be a multicast address or an IP (broadcast) address.
`rvTrdpMCHostDataPkts` | Number of data packets for this triple.
`rvTrdpMCHostDataBytes` | Number of payload bytes in data packets for this triple.
`rvTrdpMCHostRtPkts` | Number of retransmission packets for this triple.
`rvTrdpMCHostRtBytes` | Number of payload bytes in retransmission packets for this triple.
`rvTrdpMCHostNullPkts` | Number of null packets for this triple.
`rvTrdpMCHostSeqGaps` | Number of requested sequence numbers summed over all retransmission requests for this triple. Each retransmission request packet can solicit one or more data packets for retransmission. This object sums the number of data packets for which retransmission is requested. For more information, see Diagnoses.
`rvTrdpMCHostBadPkts` | Number of bad multicast or broadcast packets for this triple.
Multicast Retransmission Host Snapshot
`rvTrdpRtHostTable` | Table of multicast retransmission statistics, with one entry for each pair of host (rvTrdpRtHostAddr) and service port (rvTrdpRtPort). Entries in this table count several types of packets related to the retransmission request protocol for multicast or broadcast data.
`rvTrdpRtPort` | Service port of packets counted in the table entry.
`rvTrdpRtHostAddr` | IP address of the host that is the source or destination of packets counted in the table entry.
`rvTrdpRtReqPktsSrc` | Number of retransmission request packets sent by the host (that is, the host is the source of the request packet). These packets indicate that the receiving Rendezvous daemon on the host missed inbound data packets, and has requested retransmission. Each request packet counts separately, even if several request packets specify the same data packet numbers for retransmission.
`rvTrdpRtReqSeqSrc` | Number of data packet sequence numbers requested by the host (that is, the host is the source of the request). Each retransmission request packet can solicit one or more data packets for retransmission. This item counts the number of data packets for which the host requested retransmission, summing them over the request packets (as counted by rvTrdpRtReqPktsSrc). If the host requests some data packets several times, each data packet counts separately each time the host requests it. For more information, see Diagnoses.
`rvTrdpRtRejPktsSrc` | Number of retransmission rejection notices sent by the host (that is, the host is the source of the rejection packet). Although Rendezvous daemons comply with retransmission requests whenever possible, sometimes the requested data packets are no longer available.
`rvTrdpRtBadPktsSrc` | Number of bad retransmission request packets sent by the host (that is, the host is the source of the bad packet). Bad packets lack UDP checksums, or are corrupt in some other way. Warning See Bad Packets.
`rvTrdpRtReqPktsDest` | Number of retransmission request packets indicating the host as destination. These packets indicate that receiving Rendezvous daemons missed data, and requested retransmission from the host. Each request packet counts separately, even if several request packets specify the same data packet numbers for retransmission.
`rvTrdpRtReqSeqDest` | Number of data packet sequence numbers requested from the host. Each retransmission request packet can solicit one or more data packets for retransmission. This item counts the number of data packets requested, summing them over the request packets (as counted by rvTrdpRtReqPktsDest). If several daemons request a data packet several times, each request counts separately. For more information, see Diagnoses.
`rvTrdpRtRejPktsDest` | Number of retransmission rejection notices indicating the host as destination. Although Rendezvous daemons comply with retransmission requests whenever possible, sometimes the requested data packets are no longer available.
`rvTrdpRtBadPktsDest` | Number of bad retransmission request packets indicating the host as destination. Bad packets lack UDP checksums, or are corrupt in some other way. Warning See Bad Packets.
