Logging Infrastructure for CF components
I have some queries regarding persistent storage of application logs and cf
component logs .
As per my understanding
-->For application logs:
we can send the application logs to doppler with help of metron agent and
further stream using traffic controller (User Side).
-->For CF component syslog:
We can send cf component syslog via metron to custom syslog endpoint
(followed by parsing and other mining stuff)
On the operator side how can we store "Application logs for all the
applications" to a persistent storage??
If i look at firehose (or using noaa to get all the logs), it is more like
pulling model from end component side so if components before it are slow
in sending logs then there will be buffers .
Application logs are distributed on different doppler nodes based on AZ of
metron and doppler itself , so is there a need to implement something in
between doppler and traffic controller to push all the application logs ??

We're trying to make sure we understand the question here -
* Component logs do not go through loggregator today, only to the rsyslog
* All app logs would be available to an operator via the firehose.
* " it is more like pulling model from end component side so if components
before it are slow in sending logs then there will be buffers" - component
logs again are not part of the firehose - even then, there would be
buffers, but all messages are timestamped (if you're worried about
* "is there a need to implement something in between doppler and traffic
controller to push all the application logs " - not sure I understand, but
though you need at least dopper in every AZ that a metron is in today,
doppler can speak to traffic controllers cross-AZ.
Did that help?
