Zabbix missing some data sent by agent

[pranky]

Hello Friends,
I have created my agent which is sending log data to the zabbix server with the type of information text ,and getting the log data in the table history_text table,

problem: sometimes zabbix missed this data to update in the server

agent is sending log data to the zabbix server which is showing in the zabbix log as

20951:20120117:205453.509 Trapper got [{"request":"sender data",
"data":[

20951:20120117:205453.612 Trapper got [{"request":"sender data",


but sometimes zabbix missed this data to update in the server

and the behaviour is unpredictable .


Does zabzix get the whole data send by the agent or not ..?

why zbx_tcp_check_security returns fail

Hello Friends,
As I have found that below function zbx_tcp_check_security inside the function process_mass_data code in the trapper.c file gives the error

static void process_mass_data(zbx_sock_t *sock, zbx_uint64_t proxy_hostid, AGENT_VALUE *values,
int value_num, int *processed, time_t proxy_timediff)
{
/*
Some code

*/
if (item.type == ITEM_TYPE_TRAPPER &&
FAIL == zbx_tcp_check_security(sock, item.trapper_hosts, 1))
{
zabbix_log(LOG_LEVEL_WARNING, "Process data failed: %s", zbx_tcp_strerror());
continue;
}

/*
Some code
*/
}

in this code the function
zbx_tcp_check_security(sock, item.trapper_hosts, 1) returns fail

what does mean by this zbx_tcp_check_security , and why is it being fail.



Please suggest me if anyone knows its urgent , its urgent


Thanks

zbx_tcp_check_security(sock, item.trapper_hosts, 1))

can any one please tell me the functionality of the function zbx_tcp_check_security(sock, item.trapper_hosts, 1))

or

the definition of the function

or how can I get more log of this function ,so that I can trace the error


Please Help me

Are you sure the problem lies with zbx_tcp_check_security? Because then it would produce an entry in your log which it apparently didn't.
The function itself checks if the IP of the host sending the data is allowed to do this.
