NetXMS Communication Protocol (NXCP) is a protocol used by all NetXMS entities (server, agents, clients) for communications. Protocol is message-oriented and designed to work on top of TCP protocol.
Message Format
Message Structure
Message in NXCP consists of a header and an optional payload which follows header immediatelly. Padding bytes can be added at the end of a message to make it aligned to 8-bytes boundary. Here is general message structure:
| Header
16 bytes |
Payload
0 – 256K bytes |
Padding
0-7 bytes |
Message Header
Header have the following format:
| Field | Size (bytes) | Meaning |
| CODE | 2 | Command code. List of well-known command codes can be found in Appendix A. |
| FLAGS | 2 | Flags – see explanation below |
| SIZE | 4 | Size of a message in bytes, including header and padding |
| ID | 4 | Message identifier (usually used to match replies to requests) |
| DF_COUNT | 4 | Number of data fields or size of raw data, depending on flags |
In the FLAGS field, the following bit flags (or combination of them) can be used:
| Flag | Value | Meaning |
| BINARY | 0x0001 | Message contains raw binary data instead of structured data fields. If this flag is set, DF_COUNT contains size of raw data in bytes. |
| END_OF_FILE | 0x0002 | For file transfer operations, indicates that message contains last part of a file. |
| DONT_ENCRYPT | 0x0004 | Used internally by libnetxms to indicate that message should not be encrypted on sending. Has no meaning for the receiver. |
| END_OF_SEQUENCE | 0x0008 | Indicates that message contains last portion of data. |
| REVERSE_ORDER | 0x0010 | Indicates that data coming in a set of messages will arrive in reverse order (event log records, for example). |
| CONTROL | 0x0020 | Indicates control message. Control messages doesn't contain payload part, and header fileds may have special meaning. See below for detailed control messages list. |
All fileds have network byte order.
Data Element (Variable)
Structured message's payload consist of one or more data elements, or variables. Each variable has the following structure:
| Variable ID
4 bytes |
Data Type
1 byte |
Padding
1 byte |
Data
0-256K bytes (depending on data type) |
Padding
0-7 bytes |
Size of each element should be a multiplier of 8, so up to 7 padding bytes can be appended as necessary.
Variable ID is a unique identifier of a variable in a message scope. List of well-known message ID's can be found in Appendix B.
Data type can be one of the following:
| Symbolic name | Value | Description |
| INTEGER | 0 | 32-bit integer value |
| STRING | 1 | String value |
| INT64 | 2 | 64-bit integer value |
| INT16 | 3 | 16-bit integer value |
| BINARY | 4 | Raw binary data |
| FLOAT | 5 | 64-bit floating point value |
All numeric values have network byte order.
Actual format of data filed determined by variable's data type – see below.
INTEGER
| Padding
2 bytes |
Integer value (32-bit)
4 bytes |
STRING
| Padding
2 bytes |
Length
4 bytes |
Content
0 – 256K bytes |
Strings encoded in two-byte UNICODE (UCS-2), with network byte order. Length specified in bytes.
INT64
| Padding
2 bytes |
Integer value (64-bit)
8 bytes |
INT16
| Integer value (16-bit)
2 bytes |
BINARY
| Padding
2 bytes |
Length
4 bytes |
Content
0 – 256K bytes |
FLOAT
| Padding
2 bytes |
Floating point value (64-bit)
8 bytes |
Client-Server Communications
General Description
Communication session between client and server always initiated by client. All messages can be divided into three categories – request, response, and notification. Request messagess sent by client to ask server for information or to instruct it to do something. Server replies with response messages, which usually contains request completion code and, depending on request, some additional data. If amount of data to be transferred is large, server may send many response messages to one request. Server may also send notification messages to inform client about various events – for example, change in object's status.
Typical client-server session scenario
Usually client-server communication session looks as following:
| Client message | Server message |
| CMD_GET_SERVER_INFO | |
| CMD_REQUEST_COMPLETED | |
| CMD_LOGIN | |
| CMD_LOGIN_RESP | |
| Data request or command | |
| CMD_REQUEST_COMPLETED | |
| ... |
Request messages
CMD_CONFIG_GET_CLOB
Get value of configuration variable containing large string.
Variables
| Variable | Type | Description |
| VID_NAME | STRING | Variable name |
Response: CMD_REQUEST_COMPLETED with VID_VALUE set to variable's value.
CMD_CONFIG_SET_CLOB
