if you're using bosh to manage cloud foundry, then the bosh cli has a
command:
bosh vms --vitals

which you can read about here [1], that does a good job of measuring infra
concerns:

- Vitals: Includes load, CPU, memory, swap, system disk, ephemeral
disk, and persistent disk usage for each VM.

Hi all :)

I got a task to check the possibility to fetch details such as:
- overall used and available memory/storage usage of cf platform
- list of running warden containers, approximation how many can be
spawned additionally
I looked through https://apidocs.cloudfoundry.org/218/ but did not find
anything similar to whats I am looking for.

Are there any options other than standard os level monitoring?

BR,
Rafal.

Hi,
we want to make the apps on our landscape trust a certain ca certificate
of a ca we run internally. I came across the instructions on how to do this
for the JRE buildpack:
https://github.com/cloudfoundry/java-buildpack/blob/master/docs/jre-open_jdk_jre.md#custom-ca-certificates

I understand doing this once in the JRE buildpack will directly make all
the java apps that of course need to make use of the JRE buildpack trusting
our internal ca. Is that correct or do I need to change other buildpacks as
well?

However this implies performing a fork of the JRE buildpack. A fork means
that we always need to synchronize manually with the newer versions of the
build pack.

How do you approach this problem in your organization? I suppose you also
have internal certificate authorities that need to be trusted, right?

Also I am asking myself whether there is a way to enhance the default
buildpack allowing an application (instead of the buildpack) to bring their
own, additional certificates?

thx
Mathias

This is a pretty tricky one, as it takes a long time to manifest. After a
while without a restart, cloud_controller_ng take a long time listing org
users. For example, in an org with 350 users, before restart `cf org-users
ORG` took 1:20. After restart, the call took 0:07. We've only notice this
twice, both times after the cloud controller had been running for a couple
weeks without a restart.

Looking in New Relic, the breakdown of an individual call to
organization/guid/managers shows the majority of the call externally:

Though uaa itself isn't the issue, as things are fine immediately after
restarting cloud_controller_ng (and restarting uaa has no affect).

Have other Cloud Foundry operators seen this degraded performance? Is
there other information we could provide to turn this into a workable bug
report?

The DEA is trying to run a script in the warden container to untar the
droplet. For some reason, the user executing the script and the file
system permissions in the container in the /home/vcap directory are not
what they're supposed to be. I believe you are deploying and running all
the Cloud Foundry components in a non-standard way. You may wish to try a
more standard deployment, and look at the differences in users and file
system permissions between the standard deployment and your deployment, and
reverse-engineer what would need to be fixed in your deployment to get
things to work. Here's a blog post, at the end it talks about how you can
get a session into a warden container (
http://andypiper.co.uk/2014/02/17/getting-inside-cloud-foundry-for-debug-and-profit/).
Alternatively you can look at the startup scripts used in the standard
deployments, e.g. (
https://github.com/cloudfoundry/cf-release/blob/master/jobs/dea_next/templates/dea_ctl.erb
).

Since you've configured all your components in a very idiosyncratic
manner, it's hard to say generally what you need to fix to get all the
permissions right.

Hi.

We deployed a php application using 'gettext' extension to manage i18n
function. (*1)

We tried to activate i18n, however, it didn't work in this php application
after all.
We also tested with a simple application which contains 'gettext', but it
seemed that the extension still doesn't work.(*2)

Is there anyone who uses i18n well by using 'gettext' extension in PHP
applications?

http://blog.cloudfoundry.gr.jp/2015/09/cf100apps-067-fc2blog.html
----------
(*2)

This result should be `/home/vcap/app/htdocs/locale: Hello, world` , if
'gettext' extension works well.

Thanks.

runtime it needs this info in my logic.
