RRD stops collecting after my WAN IP changes

loupalladino

Hi Everyone
About two weeks ago, I upgraded from an RC of 2.1 to the full 2.1 release. Since then, each time my ISP assigns me a new DHCP address, my RRD Graphs stop collecting data. The timestamps on the files coincide directly with the IP change. If I hit "Reset RRD Data", it will fix the problem until the next IP change.

Thoughts?

I have the same issue however. Both my LAN and WAN traffic graphs are blank.

Got it working. Reset the rrd data and restart the rrd graphing backend. All found in the rrd settings tab.

Let me know if it breaks again when your IP changes.

I've seen similar problem when IP changes.

I noticed that these two processes [re?]appear after I hit the reset button for RRD graphs:

root 41842 0.2 0.1 3644 1476 ?? SN 6:24PM 0:00.03 /bin/sh /var/db/rrd/updaterrd.sh
root 54720 0.2 0.1 1512 776 ?? SN 6:24PM 0:00.00 sleep 60

I'm guessing that is the script that dies for whatever reason after the IP change and gets "kicked" again after the reset.

I'll keep poking.

if ($_POST['ResetRRD']) {
	mwexec('/bin/rm /var/db/rrd/*');
	enable_rrd_graphing();
	setup_gateways_monitor();
	$savemsg = "RRD data has been cleared. New RRD files have been generated.";

Something in there is causing it to start working again. The script is always running.

/*
 * We need to force sync VPNs on such even when the IP is the same for dynamic interfaces.
 * Even with the same IP the VPN software is unhappy with the IP disappearing, and we
 * could be failing back in which case we need to switch IPs back anyhow.
 */
if (!is_ipaddr($oldip) || $curwanip != $oldip || !is_ipaddrv4($config['interfaces'][$interface]['ipaddr'])) {
	/* reconfigure static routes (kernel may have deleted them) */
	system_routing_configure($interface);

	/* reconfigure our gateway monitor */
	setup_gateways_monitor();

	file_put_contents("{$g['vardb_path']}/{$interface}_cacheip", $curwanip);

	/* perform RFC 2136 DNS update */
	services_dnsupdate_process($interface);

	/* signal dyndns update */
	services_dyndns_configure($interface);

	/* reconfigure IPsec tunnels */
	vpn_ipsec_force_reload($interface);

	/* start OpenVPN server & clients */
	if (substr($interface_real, 0, 4) != "ovpn")
		openvpn_resync_all($interface);

	/* reload graphing functions */
	enable_rrd_graphing();

	/* reload igmpproxy */
	services_igmpproxy_configure();

	/* restart snmp */
	services_snmpd_configure();

Looks like if the new ip isn't = to the old ip it is supposed to run enable_rrd_graphing() so it should be fixing it? Ipv6 or ipv4 ip?

Anything in your logs about rrd having problems. What does your log say when your IP changes.
