NSX Event Catalog

The following tables describe events that trigger alarms in VMware NSX®, including alarm messages and recommended actions to resolve them. Any event with a severity greater than LOW triggers an alarm. Alarms information is displayed in several locations within the NSX Manager interface. Alarm and event information is also included with other notifications in the Notifications drop-down menu in the title bar. To view alarms, navigate to the Home page and click the Alarms tab. For more information on alarms and events, see " Working with Events and Alarms" in the NSX Administration Guide

Alarm Management Events

Alarm Service Overloaded Critical global-manager, manager

The alarm service is overloaded.

When event detected: "Due to heavy volume of alarms reported, the alarm service is temporarily overloaded. The NSX UI and GET /api/v1/alarms NSX API have stopped reporting new alarms; however, syslog entries and SNMP traps (if enabled) are still being emitted reporting the underlying event details. When the underlying issues causing the heavy volume of alarms are addressed, the alarm service will start reporting new alarms again. "

When event resolved: "The heavy volume of alarms has subsided and new alarms are being reported again. "

Review all active alarms using the Alarms page in the NSX UI or using the GET /api/v1/alarms?status=OPEN,ACKNOWLEDGED,SUPPRESSED NSX API. For each active alarm investigate the root cause by following the recommended action for the alarm. When sufficient alarms are resolved, the alarm service will start reporting new alarms again.

Audit Log File Update Error Critical global-manager, manager, edge, public-cloud-gateway, esx, kvm, bms

At least one of the monitored log files cannot be written to.

When event detected: "At least one of the monitored log files has read-only permissions or has incorrect user/group ownership on Manager, Global Manager, Edge, Public Cloud Gateway, KVM or Linux Physical Server nodes. Or log folder is missing in Windows Physical Server nodes. Or rsyslog.log is missing on Manager, Global Manager, Edge or Public Cloud Gateway nodes. "

When event resolved: "All monitored log files have the correct file permissions and ownership on Manager, Global Manager, Edge, Public Cloud Gateway, KVM or Linux Physical Server nodes. And log folder exists on Windows Physical Server nodes. And rsyslog.log exists on Manager, Global Manager, Edge or Public Cloud Gateway nodes. "

1. On Manager and Global Managaer nodes, Edge and Public Cloud Gateway nodes, Ubuntu KVM Host nodes ensure the permissions for the /var/log directory is 775 and the ownership is root:syslog. One Rhel KVM and BMS Host nodes ensure the permission for the /var/log directory is 755 and the ownership is root:root.
2. On Manager and Global Manager nodes, ensure the file permissions for auth.log, nsx-audit.log, nsx-audit-write.log, rsyslog.log and syslog under /var/log is 640 and ownership is syslog:admin.
3. On Edge and Public Cloud Gateway nodes, ensure the file permissions for rsyslog.log and syslog under /var/log is 640 and ownership is syslog:admin.
4. On Ubuntu KVM Host and Ubuntu Physical Server nodes, ensure the file permissions of auth.log and vmware/nsx-syslog under /var/log is 640 and ownership is syslog:admin.
5. On Rhel KVM Host nodes and Centos/Rhel/Sles Physical Server nodes, ensure the file permission of vmware/nsx-syslog under /var/log is 640 and ownership is root:root.
6. If any of these files have incorrect permissions or ownership, invoke the commands chmod &ltmode> &ltpath> and chown &ltuser>:&ltgroup> &ltpath>.
7. If rsyslog.log is missing on Manager, Global Manager, Edge or Public Cloud Gateway nodes, invoke the NSX CLI command restart service syslog which restarts the logging service and regenerates /var/log/rsyslog.log.
8. On Windows Physical Server nodes, ensure the log folder: C:\ProgramData\VMware\NSX\Logs exists. If not, re-install NSX on the Windows Physical Server nodes.

3.1.0
Remote Logging Server Error Critical global-manager, manager, edge, public-cloud-gateway

Log messages undeliverable due to incorrect remote logging server configuration.

When event detected: "Log messages to logging server {hostname_or_ip_address_with_port} ({entity_id}) cannot be delivered possibly due to an unresolvable FQDN, an invalid TLS certificate or missing NSX appliance iptables rule. "

When event resolved: "Configuration for logging server {hostname_or_ip_address_with_port} ({entity_id}) appear correct. "

1. Ensure that {hostname_or_ip_address_with_port} is the correct hostname or IP address and port.
2. If the logging server is specified using a FQDN, ensure the FQDN is resolvable from the NSX appliance using the NSX CLI command nslookup &ltfqdn>. If not resolvable, verify the correct FQDN is specified and the network DNS server has the required entry for the FQDN.
3. If the logging server is configured to use TLS, verify the specified certificate is valid. For example, ensure the logging server is actually using the certificate or verify the certificate has not expired using the openssl command openssl x509 -in &ltcert-file-path> -noout -dates.
4. NSX appliances use iptables rules to explicitly allow outgoing traffic. Verify the iptables rule for the logging server is configured properly by invoking the NSX CLI command verify logging-servers which re-configures logging server iptables rules as needed.
5. If for any reason the logging server is misconfigured, it should be deleted using the NSX CLI `del logging-server &lthostname-or-ip-address[:port]> proto &ltproto> level &ltlevel>` command and re-added with the correct configuration.

Communication Events

Event Name Severity Node Type Alert Message Recommended Action Release Introduced
Limited Reachability On DPU Medium dpu

The given collector can not be reached via vmknic(s) on given DVS on DPU.

When event detected: "The {vertical_name} collector {collector_ip} can not be reached via vmknic(s)(stack {stack_alias}) on DVS {dvs_alias} on DPU {dpu_id}, but is reachable via vmknic(s)(stack {stack_alias}) on other DVS(es). "

When event resolved: "The {vertical_name} collector {collector_ip} can be reached via vmknic(s) (stack {stack_alias}) on DVS {dvs_alias} on DPU {dpu_id}, or the {vertical_name} collector {collector_ip} is unreachable completely. "

If the warning is on, it does not mean the collector is unreachable. The exported flows generated by the vertical based on DVS {dvs_alias} can still reach the collector {collector_ip} via vmknic(s) on DVS(es) besides of DVS {dvs_alias}. If this is unacceptable, user can try to create vmknic(s) with stack {stack_alias} on DVS {dvs_alias} and configure it with approriate IPv4(6) address, then check if the {vertical_name} collector {collector_ip} can be reached via the newly-created vmknic(s) on DPU {dpu_id} by invoking vmkping {collector_ip} -S {stack_alias} -I vmkX with SSH to DPU via ESXi enabled.

4.0.1
Unreachable Collector On DPU Critical dpu

The given collector can not be reached via existing vmknic(s) on DPU at all.

When event detected: "The {vertical_name} collector {collector_ip} can not be reached via existing vmknic(s)(stack {stack_alias}) on any DVS on DPU {dpu_id}. "

When event resolved: "The {vertical_name} collector {collector_ip} can be reached with existing vmknic(s)(stack {stack_alias}) now on DPU {dpu_id}. "

To make the collector reachable for given vertical on the DVS, user has to make sure there is(are) vmknic(s) with expected stack {stack_alias} created and configured with approriate IPv4(6) addresses, and the network connection to {vertical_name} collector {collector_ip} is also fine. So user has to do the checking on DPU {dpu_id}, and perform required configuration to make sure the condition is met. Finally if vmkping {collector_ip} -S {stack_alias} with SSH to DPU via ESXi enabled succeeds, this indicates the problem is gone.

4.0.1
Manager Cluster Latency High Medium manager

The average network latency between Manager nodes is high.

When event detected: "The average network latency between Manager nodes {manager_node_id} ({appliance_address}) and {remote_manager_node_id} ({remote_appliance_address}) is more than 10ms for the last 5 minutes. "

When event resolved: "The average network latency between Manager nodes {manager_node_id} ({appliance_address}) and {remote_manager_node_id} ({remote_appliance_address}) is within 10ms. "

Ensure there are no firewall rules blocking ping traffic between the Manager nodes. If there are other high bandwidth servers and applications sharing the local network, consider moving these to a different network.

When event resolved: "The Transport node {entity_id} restores the control plane connection to Manager node {appliance_address}. "

1. Check the connectivity from Transport node {entity_id} to Manager node {appliance_address} interface via ping. If they are not pingable, check for flakiness in network connectivity.
2. Check to see if the TCP connections are established using the netstat output to see if the Controller service on the Manager node {appliance_address} is listening for connections on port 1235. If not, check firewall (or) iptables rules to see if port 1235 is blocking Transport node {entity_id} connection requests. Ensure that there are no host firewalls or network firewalls in the underlay are blocking the required IP ports between Manager nodes and Transport nodes. This is documented in our ports and protocols tool which is here: https://ports.vmware.com/ .
3. It is possible that the Transport node {entity_id} may still be in maintenance mode. You can check whether the Transport node is in maintenance mode via the following API: GET https://&ltnsx-mgr>/api/v1/transport-nodes/&lttn-uuid>. When maintenance mode is set, the Transport node will not be connected to the Controller service. This is usually the case when host upgrade is in progress. Wait for a few minutes and check connectivity again.

This API request triggers a DNS lookup to the upstream server in the DNS forwarder's network namespace. &ltaddress> is the IP address or FQDN in the same domain as the upstream server. &ltsource_ip> is an IP address in the upstream server's zone. If the API returns a connection timed out response, there is likely a network error or upstream server problem. Check why DSN lookups are not reaching the upstream server or why the upstream server is not returning a response. If the API response indicates the upstream server is answering, proceed to step 2.
2. Invoke the NSX API GET /api/v1/dns/forwarders/{dns_id}/nslookup? address=&ltaddress>. This API request triggers a DNS lookup to the DNS forwarder.

Edge NIC Out Of Receive Buffer Medium edge, autonomous-edge, public-cloud-gateway

Edge node NIC is out of RX ring buffers temporarily.

When event detected: "Edge NIC {edge_nic_name} receive ring buffer has overflowed by {rx_ring_buffer_overflow_percentage}% on Edge node {entity_id}. The missed packet count is {rx_misses} and processed packet count is {rx_processed}. "

When event resolved: "Edge NIC {edge_nic_name} receive ring buffer usage on Edge node {entity_id} is no longer overflowing. "

Run the NSX CLI command get dataplane cpu stats on the edge node and check:
1. If cpu usage is high, i.e., > 90%, then take a packet capture on the interface using the command `start capture interface &ltinterface-name> direction input or start capture interface &ltinterface-name> direction input core &ltcore-id>` (to capture packets ingressing on specific core whose usage is high). Then analyze the capture to see if there are majority of fragmented packets or ipsec packets. If yes, then it is expected behavior. If not, datapath is probably busy with other operations. If this alarm lasts more than 2-3 minutes, contact VMware Support.
2. If cpu usage is not high, i.e., < 90%, then check if rx pps is high using the command get dataplane cpu stats (just to make sure the traffic rate is increasing). Then increase the ring size by 1024 using the command set dataplane ring-size rx . NOTE - The continuous increase of ring size by 1024 factor can lead to some performance issues. If even after increasing the ring size, the issue persists then it is an indication that edge needs a larger form factor deployment to accommodate the traffic.
3. If the alarm keeps on flapping i.e., triggers and resolves very soon, then it is due to bursty traffic. In this case check if rx pps as described above, if it is not high during the alarm active period then contact VMware Support. If pps is high it confirms bursty traffic. Consider suppressing the alarm. NOTE - There is no specific benchmark to decide what is regarded as a high pps value. It depends on infrastructure and type of traffic. The comparison can be made by noting down when alarm is inactive and when it is active.

Edge NIC Out Of Transmit Buffer Critical edge, autonomous-edge, public-cloud-gateway

Edge node NIC is out of TX ring buffers temporarily.

When event detected: "Edge NIC {edge_nic_name} transmit ring buffer has overflowed by {tx_ring_buffer_overflow_percentage}% on Edge node {entity_id}. The missed packet count is {tx_misses} and processed packet count is {tx_processed}. "

When event resolved: "Edge NIC {edge_nic_name} transmit ring buffer usage on Edge node {entity_id} is no longer overflowing. "

1. If a lot of VMs are accommodated along with edge by the hypervisor then edge VM might not get time to run, hence the packets might not be retrieved by hypervisor. Then probably migrating the edge VM to a host with fewer VMs.
2. Increase the ring size by 1024 using the command `set dataplane ring-size tx `. If even after increasing the ring size, the issue persists then contact VMware Support as the ESX side transmit ring buffer might be of lower value. If there is no issue on ESX side, it indicates the edge needs to be scaled to a larger form factor deployment to accommodate the traffic.
3. If the alarm keeps on flapping, i.e., triggers and resolves very soon, then it is due to bursty traffic. In this case check if tx pps using the command get dataplane cpu stats. If it is not high during the alarm active period then contact VMware Support. If pps is high it confirms bursty traffic. Consider suppressing the alarm. NOTE - There is no specific benchmark to decide what is regarded as a high pps value. It depends on infrastructure and type of traffic. The comparison can be made by noting down when alarm is inactive and when it is active.

Load Balancer Events

Event Name Severity Node Type Alert Message Recommended Action Release Introduced
LB CPU Very High Medium edge

Load balancer CPU usage is very high.

When event detected: "The CPU usage of load balancer {entity_id} is very high. The threshold is {system_usage_threshold}%. "

When event resolved: "The CPU usage of load balancer {entity_id} is low enough. The threshold is {system_usage_threshold}%. "

If the load balancer CPU utilization is higher than system usage threshold, the workload is too high for this load balancer. Rescale the load balancer service by changing the load balancer size from small to medium or from medium to large. If the CPU utilization of this load balancer is still high, consider adjusting the Edge appliance form factor size or moving load balancer services to other Edge nodes for the applicable workload.

LB Status Degraded Medium manager

Load balancer service is degraded.

When event detected: "The load balancer service {entity_id} is degraded. "

When event resolved: "The load balancer service {entity_id} is not degraded. "

For centralized load balancer: Check the load balancer status on standby Edge node as the degraded status means the load balancer status on standby Edge node is not ready. On standby Edge node, invoke the NSX CLI command get load-balancer &ltlb-uuid> status. If the LB-State of load balancer service is not_ready or there is no output, make the Edge node enter maintenance mode, then exit maintenance mode. For distributed load balancer:
1. Get detailed status by invoking NSX API GET /policy/api/v1/infra/lb-services/&ltLBService>/detailed-status?source=realtime
2. From API output, find ESXi host reporting a non-zero instance_number with status NOT_READY or CONFLICT.
3. On ESXi host node, invoke the NSX CLI command `get load-balancer &ltlb-uuid> status`. If 'Conflict LSP' is reported, check whether this LSP is attached to other load balancer service. Check whether this conflict is acceptable. If 'Not Ready LSP' is reported, check the status of this LSP by invoking NSX CLI command get logical-switch-port status. NOTE: You should ignore the alarm if it can be resolved automatically in 5 mins because the degraded status can be a transient status.
