NAME

CNET_get_nodestats - obtain runtime statistics about the current node

SYNOPSIS

#include <cnet.h>

typedef struct {
    int64_t     nevents;
    int64_t     nerrors;

    int64_t     msgs_generated;
    int64_t     bytes_generated;

    int64_t     msgs_received;
    int64_t     bytes_received;
} CnetNodeStats;

int CNET_get_nodestats(CnetNodeStats *stats);

DESCRIPTION

CNET_get_nodestats() provides the current node with statistics about its own execution.

A node's statistics are cleared when the node reboots. The "sum" of each node's statistics form the global node statistics which are reported on the GUI and may be requested with the -s command-line option.

RETURN VALUE

The value 0 is returned on success. On failure, the value -1 is returned, and the global variable cnet_errno is set to one of the following values to describe the error:

ER_BADARG

stats was a NULL pointer.
