Re: [Apcupsd-users] protocol of the 3551 port

[Adam K. <ad...@kr...>]

I was responding to the part of your question that said, "Or is there
already a monitor program for Window?", to which the answer is "Yes, it's
called apcupsd." :-)

As for the network protocol, I could have sworn I've described it many
times over the years, but Google is failing me so here goes once more. This
time I'll put it in the manual...

The protocol operates over TCP. The client opens a connection to the server
> and sends a message, to which the server will reply with one or more
> messages. Each message consists of a 2-byte length (in network byte order)
> followed by that many bytes of data. Both the client->server and
> server->client messages follow this format.

> apcupsd supports 2 commands, sent as the body of a message:

1. "status" - The status command requests that the server send a copy of
all status values, in the form displayed by apcaccess. After the client
sends the "status" command, the server will reply with a series of messges,
each one containing one line of apcaccess status data. The end of the
command series is indicated by an empty message (length of 0).

2. "events" - The events command operates the same as "status" except the
server replies with lines from the log of recent events.

As an example, the following bytes would be sent by a client to solicit the
status:

    0x00 0x06 0x73 0x74 0x61 0x74 0x75 0x73

The first two bytes are the data length (6) in network byte order. The 6
bytes of data that follow are the ASCII characters for "status". The server
will respond to this command with a series of its own messages containing
the status data.

Hope this helps.
