3128:20150429:114455.871 history data from active proxy on “115.29.182.109” failed: proxy “jinrong” not found
[root@monitor src]# grep “history data from active proxy” * -r|more
zabbix_server/trapper/trapper.c: zabbix_log(LOG_LEVEL_WARNING, “history data from active proxy on ”%s” failed: %s”,
得出是trapper.c 致使。
/******************************************************************************

* *
******************************************************************************/
static void recv_proxyhistory(zbx_sock_t *sock, struct zbx_json_parse *jp)
{
const char *__function_name = "recv_proxyhistory";
zbx_uint64_t proxy_hostid;
char host[HOST_HOST_LEN_MAX], *error = NULL;
int ret;
zabbix_log(LOG_LEVEL_DEBUG, "In %s()", __function_name);
if (SUCCEED != (ret = get_active_proxy_id(jp, &proxy_hostid, host, &error)))
{
zabbix_log(LOG_LEVEL_WARNING, "history data from active proxy on "%s" failed: %s",
get_ip_by_socket(sock), error);
goto out;
}
update_proxy_lastaccess(proxy_hostid);
ret = process_hist_data(sock, jp, proxy_hostid, error, sizeof(error));
out:
zbx_send_response(sock, ret, error, CONFIG_TIMEOUT);
zbx_free(error);
zabbix_log(LOG_LEVEL_DEBUG, "End of %s()", __function_name);
}也就是说 get_active_proxy_id(jp, &proxy_hostid, host, &error)) 这个函数履行不正确的话，会报上面的错。
问题又转化为 get_active_proxy_id的履行了。
继续搜索 get_active_proxy_id 这个函数的源码文件，

分析这段源码，也就是说hosts表中查不到的时候是会报 proxy ”%s” not found 的。
MySQL [zabbix]> desc hosts;
