Kibana gateway timeout

At our organization, we have 7 primary shard Elastic Search servers serving a single Kibana frontend. The stack trace I see in my browser for Kibana is:. We can't seem to get rid of this issue.

All of the Elastic Search servers respond to requests, so I don't think that one server failing is causing Kibana to fail hard. I'm not sure who the client is, in this case. Is Kibana's connection to the ELB being terminated?

Kibana's own logs are pretty unhelpful here, nothing is logged. We set the connection idle timeout and the connection draining policy to seconds on the ELB, which is 5 minutes, and the request fails well before 5 minutes.

The client that is logging this error is the elasticsearch. It is receiving a status code from the browser, so I'm really don't think there is anything you can do in Kibana to make this work. What browser are you using? Have you checked the network traffic reported by the browser Chrome exposes a network debugging panel for instance? Sometimes the text of the response can provide a clue about what part of the stack terminated the response.

When the kibana server the one shipping with 4. We noticed that this is error is occurring if we have too many aggregations on the dashboards across large documents.

For our current requirement, we want to get the results even if it takes more time. Could you please tell us why we have this issue and how to resolve it? Elasticsearch needs lot of memory to perform the aggregations so even if the cluster health is green, we happened to have the same shard issues at our end on Kibana. We solved for it by upgrading our ec2 instance. But, this is only a temporary solution as we cannot upgrade the cluster forever the cost would be high too.

I then took the snapshot of our cluster, stored the backup on S3 and purged the data older than 2 months. This helped us to resolve for the shard failures and also save our data. Whenever we want the data from S3, we could always restore this data in a new cluster and perform the aggregations as usual. I had the same issue. The solution is to increase the ELB idle timeout to something above 60s, which is the default. Unable to resolve Gateway Timeout errors Kibana. Why am I getting this Gateway Timeout exception and what can I do to fix the problem?

What versions of Kibana and Elasticsearch are you running? Kibana is the latest, 4. Elastic Search is 1. Internally, NGINX throws awhich means that: Client Closed Request Nginx Used in Nginx logs to indicate when the connection has been closed by client while the server is still processing its request, making server unable to send a status code back. Hi, We are currently using Amazon elasticsearch service and Kibana 4.Learn how to troubleshoot bad gateway errors received when using Azure Application Gateway.

This article has been updated to use the new Azure PowerShell Az module. You can still use the AzureRM module, which will continue to receive bug fixes until at least December After configuring an application gateway, one of the errors that you may see is "Server Error: - Web server received an invalid response while acting as a gateway or proxy server".

This error may happen for the following main reasons:. This causes probe failures, resulting in errors. When an application gateway instance is provisioned, it automatically configures a default health probe to each BackendAddressPool using properties of the BackendHttpSetting.

No user input is required to set this probe. Specifically, when a load-balancing rule is configured, an association is made between a BackendHttpSetting and a BackendAddressPool. A default probe is configured for each of these associations and the application gateway starts a periodic health check connection to each instance in the BackendAddressPool at the port specified in the BackendHttpSetting element. Custom health probes allow additional flexibility to the default probing behavior.

When you use custom probes, you can configure the probe interval, the URL, the path to test, and how many failed responses to accept before marking the back-end pool instance as unhealthy. Validate that the Custom Health Probe is configured correctly as the preceding table. In addition to the preceding troubleshooting steps, also ensure the following:. When a user request is received, the application gateway applies the configured rules to the request and routes it to a back-end pool instance.

It waits for a configurable interval of time for a response from the back-end instance. By default, this interval is 20 seconds. If the application gateway does not receive a response from back-end application in this interval, the user request gets a error.

Application Gateway allows you to configure this setting via the BackendHttpSetting, which can be then applied to different pools. Different back-end pools can have different BackendHttpSetting, and a different request time-out configured. If the application gateway has no VMs or virtual machine scale set configured in the back-end address pool, it can't route any customer request and sends a bad gateway error.

Ensure that the back-end address pool isn't empty. The output from the preceding cmdlet should contain non-empty back-end address pool. The provisioning state of the BackendAddressPool must be 'Succeeded'.

If all the instances of BackendAddressPool are unhealthy, then the application gateway doesn't have any back-end to route user request to.

This can also be the case when back-end instances are healthy but don't have the required application deployed. Ensure that the instances are healthy and the application is properly configured.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

That typically means that an intermediate proxy wasn't able to satisfy a request with a backend. This probably means that HAProxy is either unable to route requests to Elasticsearch, or requests are timing out. Check your HAProxy logs. Active Oldest Votes.

Likely because of the readiness probe.

Elasticsearch is a resource hog and more is better. Note this amount is split in half because of how Elasticsearch utilizes memory and the temp space made available to the container.

Your max operational heap in your example is 4G which is not much at all if there is any significant load on the cluster. You could remove the readiness probes to ensure the pods don't get prematurally restarted by the platform and then we could correct after they nodes cluster.

The first request takes from 20 to 50 seconds and succeeds, the second request is always finished with a gateway timeout after exactly two minutes. When running the query generated by Kibana directly against one of the Elasticsearch nodes, the query takes about 7 minutes and completes successfully. When running the query without the ELB directly against one of the Kibana instances using curl it also fails after pretty much exactly two minutes.

Turns out, one of the sockets used also had a timeout. This pull request contains links to commits of which parts can be used to fix Kibana 4. Learn more. Asked 2 years, 11 months ago.

In some cases, an assigned VIP might bind to all master nodes. This binding issue usually occurs in VMWare clusters that do not have vrrp enabled. To fix this issue, you need to configure your VMWare network to have vrrp enabled. See Configuring your cluster. If you are using Cloud Automation Manager version 2.

During the installation of the Helm Cli you might observe an error message that resembles the following output:. Docker version Instability issues are reported or observed with Docker version To avoid these issues, use a supported version of Docker. For a list of supported versions, see Supported Docker Versions. Sometimes a cluster node is online, but the services that run on that node are unresponsive or return Gateway Timeout errors when you try to access them. These errors might be due to a known issue with Docker where an old containerd reference is used even after the containerd daemon was restarted.

This defect causes the Docker daemon to go into an internal error loop that uses a high amount of CPU resources and logs a high number of errors. For more information about this error, see the Refresh containerd remotes on containerd restarted pull request against the Moby project.

To determine whether this defect causes the errors, SSH into the affected node, and run the journalctl -u kubelet -f command. If you see that text, run the top command and confirm that dockerd uses a high percentage of the available CPU. To work around this issue, use the host operating system command to restart the docker service on the node. After some time, the services resume. If a pod that uses a GlusterFS PersistentVolume for storage is stuck in the Terminating state after you try to delete it, you must manually delete the pod.
