# nws\_proxy(1)

aggregate multiple series for the Network Weather Service

## NAME

nws\_proxy - aggregate multiple series for the Network Weather Service

## SYNOPSIS

**nws\_proxy** \[-N host\]\[-As\]\[-e file\]\[-l file\]\[-i file\]\[-p port\]

## DESCRIPTION

This manual page explains the  **nws\_proxy** program. The nws\_proxy can query  **[nws\_nameserver(1)](/nws_nameserver/1.md)** to find  **[nws\_memory(1)](/nws_memory/1.md)** which are responsible for NWS series and start autofetching them. It's purpose is to avoid the high latency when retrieving a large number of NWS series. It returns only the last value/forecast pair.

The **nws\_proxy** can be controlled and queried thorugh the  **[nws\_ctrl(1)](/nws_ctrl/1.md)** program (check for the  *proxy* and  *proxyFetch* command.

**WARNING:** the **nws\_proxy** can use a lot of memory if the number of series is large.

## OPTIONS

- **-e** *file*

  Save the error messages to  *file.*

- **-l** *file*

- **-s**

  This proxy is going to be a system wide proxy, so it will register with the nameserver (specified by -N).

- **-i** *file*

  Write the pid to  *file*

- **-N** *nws\_nameserver*

  Use *nws\_nameserver* to look up for NWS series.

- **-A**

  Start caching  *all* the NWS series registered with the nameserver as specified in the *-N* switch.

**-p port** Listen to port instead of the default for the nws\_proxy (8070).
