Re: F5 Load Balancer Configuration for Cloud Foundry Loggregator

Johannes Hiemer <jvhiemer@...>

Are you sure your logregator endpoint is configured on 443 and not 4443?

Yep. --recent works. Other cf commands and cf curl also works.

It definitely is the websockets for loggregator. Just not sure what the right config for F5 (version 10.4) should be.

Does `cf logs --recent` work for you? The recent logs request goes over HTTP. If that goes through that means only the websocket requests to loggregator servers are a problem.

Thanks Mike! Unfortunately, upgrading is not an option since its a really loaded enterprise device. The interesting part is that there is a similarly set up websockets vip (plain old server i think .net) that is working on the same device.

We'll work with our network folks to find other devices with newer software we can use.

Would appreciate if anyone has other ideas?

We are running 11.4 and 11.6. I'd give an upgrade a try before digging too much deeper.

What version of F5 software are you running?

Does any one have any experience configuring F5 load balancers in front of the CF routers? We have configured F5 and app https and cf push requests are working fine. However, the connectivity with loggregator is not working. Taking a look at the documentation, it requires "websocket support" on the load balancer. We've done the configuration specified here:

With the following irule basically, applying the default TCP profile if it detects websocket traffic:

if { [string tolower [HTTP::header Upgrade]] contains "websocket" }{

However, we are running into errors. Doing `cf logs myapp1` yields:

Error dialing loggregator server: read tcp <ip redacted>:443: connection reset by peer.
Please ask your Cloud Foundry Operator to check the platform configuration (loggregator endpoint is wss://loggregator.<sys domain redacted>:443).

Does anyone have a clue?
