Verifying load balancer configuration

1 users found this article helpful

Symptoms

In a multi-node Awingu environment, the number of log entries ( Download logs from an Awingu appliance ) during a specific period in different "nginx.service.log" files (one per node) is significantly different. 

Significant means that for instance one node gets more than double the amount of requests compared to the others.

Hint: compare the lines containing the "host header", e.g. lines with "yourawingu.environment.com".

Cause

There is an error somewhere in the network configuration, e.g. on the firewall, load balancer or reverse proxy server in front of Awingu.

Some examples of misconfiguration:

Resolution

Awingu itself does no load balancing of the inbound HTTP requests.

While the exact configuration of such a physical or virtual network device is out of scope of our support, the Admin Manual contains some pointers and an example configuration for Nginx.

After addressing the configuration issue, it's possible to export Awingu's log files again.
