Subject [jira] [Commented] (CLOUDSTACK-9649) In the management server log there is an error related to 0.0.0.0 IP address
Date Fri, 02 Dec 2016 10:16:58 GMT

    [ https://issues.apache.org/jira/browse/CLOUDSTACK-9649?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15714704#comment-15714704

Sudhansu Sahu commented on CLOUDSTACK-9649:
-------------------------------------------

As Link local is not used in basic zone mode (vmware). 0.0.0.0 is just shown as a placeholder
address. In getRouterAlerts before sending GetRouterAlertsCommand we can check for ip and
skip the command if ip is '0.0.0.0'.

VirtualNetworkApplianceManagerImpl.java
protected void getRouterAlerts() {
        try{
            List<DomainRouterVO> routers = _routerDao.listByStateAndManagementServer(State.Running,
mgmtSrvrId);

            s_logger.debug("Found " + routers.size() + " running routers. ");

            for (final DomainRouterVO router : routers) {
                String serviceMonitoringFlag = SetServiceMonitor.valueIn(router.getDataCenterId());
                // Skip the routers in VPC network or skip the routers where Monitor service
is not enabled in the corresponding Zone
                if ( !Boolean.parseBoolean(serviceMonitoringFlag) || router.getVpcId() !=
null) {
                    continue;
                }

                String privateIP = router.getPrivateIpAddress();

                if (privateIP != null) {
                    OpRouterMonitorServiceVO opRouterMonitorServiceVO = _opRouterMonitorServiceDao.findById(router.getId());

                    GetRouterAlertsCommand command = null;
                    if (opRouterMonitorServiceVO == null) {
                        command = new GetRouterAlertsCommand(new String("1970-01-01 00:00:00"));
// To avoid sending null value
                    } else {
                        command = new GetRouterAlertsCommand(opRouterMonitorServiceVO.getLastAlertTimestamp());
                    }
