how to change snmp timeout in zabbix poller

[xiaoquwl]

hi all,

I want to change the snmp polling timeout value, how can i do that?
I did that like below, i change the source code by add one line "session.timeout = 4",
could that be ok?
or i just change the value of "# Timeout=3" to "Timeout=4" in the zabbix_server.conf file

static struct snmp_session	*snmp_open_session(DC_ITEM *item, char *err)
{
	const char		*__function_name = "snmp_open_session";
	struct snmp_session	session, *ss = NULL;
	char			addr[128], *conn;
        #ifdef HAVE_IPV6
	int			family;
        #endif	  /* HAVE_IPV6 */

	zabbix_log(LOG_LEVEL_DEBUG, "In %s()", __function_name);

	snmp_sess_init(&session);
        [COLOR="red"]session.timeout = 4 [/COLOR]

or

### Option: Timeout
# Specifies how long we wait for agent, SNMP device or external check (in seconds).
#
# Mandatory: no
# Range: 1-30
# Default:
#Timeout=3
Timeout=4

anybody can help me?
thanks a lot
