Hi,
I was wondering if there was a (straigthforward) way to list all users
instead of using the "cf org-users" or "cf space-users" commands.
Thanks
Remi

I think I'm getting closer. In UAA I now get the error:

TokenEndpoint: Handling error: InvalidGrantException, Invalid
authorization code: ad1o9o

This must be someone trying to redeem the auth code.

If you use straight curl with something like this, what does the flow
really look like? Are there any errors in the uaa's logs?

$ curl -v -k -H "Authorization: $(cf oauth-token | tail -1)" '
https://uaa.bosh-lite.com/oauth/authorize?response_type=code&grant_type=authorization_code&client_id=ssh-proxy

The UAA should respond with a 302 and a Location header that includes a
code parameter. If not, can you use a jwt decoder against your bearer token
and verify that there's a `uaa.user` scope in the token?

I got up to 10k on an AWS deployment of HEAD of cf-release with ruby 2.2,
then started another loop on the same box with ruby 2.1. In the end, they
got up to 40-50k without showing any signs of change. I had to switch to
resolving the UAA endpoint, eventually google started responding with 302s.

I'm going to try with a cf-release 212 deployment on my bosh lite, but
eventually I want to try on the same stemcell as you're using.

/var/vcap/packages/ruby-2.1.6/lib/ruby/2.1.0/net/http.rb.initialize :879

I've experimented some with the environment and, after narrowing things
down to DNS, here's some minimal demonstrating the problem:

require "net/http"
require "uri"

# uri = URI.parse("http://uaa.example.com/info")
uri = URI.parse("https://www.google.com")

i = 0

end_time = Time.now

end


I see the issue hitting both UAA and just hitting Google. At some
point, requests start taking 5 second longer, which I assume is a timeout.
One run:

0349 Response: [200], Elapsed: 157 ms
0350 Response: [200], Elapsed: 169 ms
0351 Response: [200], Elapsed: 148 ms

0366 Response: [200], Elapsed: 5155 ms
0367 Response: [200], Elapsed: 5157 ms

Other runs are the same. How many requests it takes before things time
out varies considerably (one run started in the 10s and another took 20k
requests), but it always happens. After that, lookups take an additional 5
second and never recover to their initial speed. This is why restarting the
cloud controller fixes the issue (temporarily).

The really slow cli calls (in the 1+min range) are simply due to the
amount of paging that a fetching data for a large org does, as that 5
seconds is multiplied out over several calls. Every user is feeling this
delay, it's just that it's only unworkable pulling the large datasets from
UAA.

I was not able to reproduce timeouts using a script calling "dig"
against localhost, only inside a ruby code.

The re-iterate our setup: we're running 212 without a consul server,
just the agents. I also successfully reproduce this problem in completely
different 217 install in a different datacenter. This setup also didn't
have an actual consul server, just the agent. I don't see anything in the
release notes past 217 indicating that this is fixed.

Anyone have thoughts? This is definitely creating some real headaches
for user management in our larger orgs. Amit: is there a bug we can follow?

Amit,
1:20 delay is due to paging. The total call length for each page is
closer to 10s. Just included those two calls with paging by the cf command
line included numbers to demonstrate the dramatic difference after a
restart. Delays disappear after a restart. We're not running consul yet, so
it wouldn't be that.

We've seen issues on some environments where requests to cc that
involve cc making a request to uaa or hm9k have a 5s delay while the local
consul agent fails to resolves the DNS for uaa/hm9k, before moving on to a
different resolver.

The expected behavior observed in almost all environments is that
the DNS request to consul agent fails fast and moves on to the next
resolver, we haven't figured out why a couple envs exhibit different
behavior. The impact is a 5 or 10s delay (5 or 10, not 5 to 10). It doesn't
explain your 1:20 delay though. Are you always seeing delays that long?

Other runs are the same. How many requests it takes before things time
out varies considerably (one run started in the 10s and another took 20k
requests), but it always happens. After that, lookups take an additional 5
second and never recover to their initial speed. This is why restarting the
cloud controller fixes the issue (temporarily).

The really slow cli calls (in the 1+min range) are simply due to the
amount of paging that a fetching data for a large org does, as that 5
seconds is multiplied out over several calls. Every user is feeling this
delay, it's just that it's only unworkable pulling the large datasets from
UAA.

I was not able to reproduce timeouts using a script calling "dig"
against localhost, only inside a ruby code.

The re-iterate our setup: we're running 212 without a consul server,
just the agents. I also successfully reproduce this problem in completely
different 217 install in a different datacenter. This setup also didn't
have an actual consul server, just the agent. I don't see anything in the
release notes past 217 indicating that this is fixed.

Anyone have thoughts? This is definitely creating some real headaches
for user management in our larger orgs. Amit: is there a bug we can follow?

Amit,
1:20 delay is due to paging. The total call length for each page is
closer to 10s. Just included those two calls with paging by the cf command
line included numbers to demonstrate the dramatic difference after a
restart. Delays disappear after a restart. We're not running consul yet, so
it wouldn't be that.

We've seen issues on some environments where requests to cc that

The expected behavior observed in almost all environments is that the
DNS request to consul agent fails fast and moves on to the next resolver,
we haven't figured out why a couple envs exhibit different behavior. The
impact is a 5 or 10s delay (5 or 10, not 5 to 10). It doesn't explain your

Hey Matt,

I'm trying to think of other things that would affect only the
endpoints that interact with UAA and would be fixed after a CC restart.
I'm wondering if it's possible there are a large number of connections
being kept-alive, or stuck in a wait state or something. Could you take a
look at the netstat information on the CC and UAA next time this happens?

-Zach and Swetha

Yes /v2/info contains "app_ssh_oauth_client: "ssh-proxy"".

Though I didn't set it. It appears CC sets it by default now.


https://github.com/cloudfoundry/cf-release/blob/master/jobs/cloud_controller_ng/spec#L81

Any other ideas?

You might try moving the nameserver entry for the consul_agent in
/etc/resolv.conf on the cloud controller to the end to see if that helps.
