# rvperfs

Command

## Syntax

    rvperfs  [-service service ]
             [-network network ]
             [-daemon daemon ]
             [-subject subject ]
             [-non-vectored]
             [-cm]
             [-cm-name name ]
             [-cm-ledger filename ]
             [-cm-sync]
             [-h]

## Purpose

`rvperfs` listens for messages from `rvperfm`, gathers and reports statistics to `rvperfm` at the end of each run.

## Remarks

`rvperfs` operates passively; it sends messages only in response to requests from `rvperfm`.

You can leave process instances of `rvperfs` running idle. Each instance of `rvperfs` can report statistics from several consecutive process instances of `rvperfm`—as long as only one `rvperfm` executes at a time. You can relocate the `rvperfm` process from one host computer to another without restarting the `rvperfs` processes.

Unlike `rvperfm`, an `rvperfs` process never exits by itself. You must explicitly terminate each `rvperfs` process.

In addition to sending its statistics to `rvperfm`, `rvperfs` also prints its report to `stdout`.

Parameter | Description
`-service` `service` | `service` is the service name or UDP port number that defines the service group. See Service Selection. If you do not specify the `-service` parameter, the default value is `7599`.
`-network` `network` | `network` narrows the service group by selecting a local network by network name or IP network number (when the host computer has multiple network interfaces). It can also specify multicast addresses. See Network Selection. If you do not specify the `-network` parameter, the default value is the multicast address`";225.9.9.9"`.
`-daemon` `daemon` | The `-daemon` parameter instructs the program about how and where to find `rvd` and establish communication. See Daemon Client Socket—Establishing Connections. You can specify a daemon on a remote computer. For details, see Remote Daemon. However, the program cannot start a remote daemon automatically—you must start it manually on the remote computer. If you do not specify the `-daemon` parameter, the program finds the local daemon on TCP socket `7500`.
`-subject` `subject` | `rvperfs` listens for messages with this subject name. If this parameter is absent, then `rvperfs` uses `_perf` as a prefix to construct broadcast subjects. (When you specify the `-inbox` flag to `rvperfm`, you need not specify this `rvperfs` parameter.)
`-non-vectored` | When present, `rvperfs` receives messages individually, using an ordinary listener. When absent, `rvperfs` receives messages using a vector listener.
`-cm` | When present, `rvperfs` listens for messages using certified delivery features. If `rvperfm` also specifies `-cm`, then the programs establish a certified delivery agreement.
`-cm-name` `name` | When present, `rvperfs` specifies this reusable correspondent name when it enables certified delivery. When `-cm` is present, but `-cm-name` is not, `rvperfs` operates with a non-reusable correspondent name.
`-cm-ledger` `filename` | When present, `rvperfs` uses this ledger file. You must also supply `-cm-name`.
`-cm-sync` | When present, then operations that update the ledger file do not return until the changes are written to the storage medium. You must also supply `-cm-ledger` and `-cm-name`. When absent, the operating system writes ledger file changes to the storage medium asynchronously.
`-h` | When present, output a parameter usage list to `stdout`, and exit immediately.
