Kibana throws a "oops message

Carlos_Magalhaes · September 19, 2018, 9:17am

I am using Kibana to display dashboards for my firewall logs. There is more than enough memory, cpu and space on the machine it is running on.

Randomly I get a Oops or Refresh message that asks to refresh the page and has an error of:

Courier fetch: Request Timeout after 30000ms
Version: 6.4.0
Build: 17929
Error: Request Timeout after 30000ms
  at http://x.x.x.x:5601/bundles/vendors.bundle.js:313:150014
  at http://x.x.x.x:5601/bundles/vendors.bundle.js:313:150447

I can confirm that on the network testing with ifperf there is no issue the machine is connected to the main switch at 10gbps and the firewall is connected to the same switch at 10gbps

Any idea what I am doing wrong or what I can change to avoid this.

To be clear if I refresh the page it goes all back to normal.

Any idea what queries are causing this request timeout? It's possible that if you have a very large dashboard or an ill-crafted query, then this could be caused simply by the amount of time it takes for Elasticsearch to collect all of the data associated with the request.

Thank you @lukas I will wait on the error to happen again and will point. I don't recall it specifying a query but I could be wrong and I will confirm.

On the dashboard - yes its a large dashboard being updated every 5 minutes. There are normal vertical bar graphs, x2 heat maps on a world map.

Basically its this dashboard:

@lukas ok it happened and I managed to catch the full error:

When the error happened was there a specific visualization that wasn't showing up?
