Since 2.5.0 we stop supporting username and password for authentification.
Please use ClientId and ClientSecret.
This nifty util aggregates all the events from the firehose feature in CloudFoundry.

usage: firehose-to-syslog --api-endpoint=API-ENDPOINT --client-id=CLIENT-ID --client-secret=CLIENT-SECRET [<flags>]
Flags:
--help Show context-sensitive help (also try
--help-long and --help-man).
--debug Enable debug mode. This disables
forwarding to syslog
--api-endpoint=API-ENDPOINT Api endpoint address. For bosh-lite
installation of CF:
https://api.10.244.0.34.xip.io
--doppler-endpoint=DOPPLER-ENDPOINT
Overwrite default doppler endpoint return
by /v2/info
--syslog-server=SYSLOG-SERVER Syslog server.
--syslog-protocol="tcp" Syslog protocol (tcp/udp/tcp+tls).
--skip-ssl-validation-syslog Skip Ssl validation for syslog
--subscription-id="firehose" Id for the subscription.
--client-id=CLIENT-ID Client ID.
--client-secret=CLIENT-SECRET Client secret.
--skip-ssl-validation Please don't
--fh-keep-alive=25s Keep Alive duration for the firehose
consumer
--min-retry-delay=500ms Doppler Cloud Foundry Doppler min. retry
delay duration
--max-retry-delay=1m Doppler Cloud Foundry Doppler max. retry
delay duration
--max-retry-count=1000 Doppler Cloud Foundry Doppler max. retry
Count duration
--logs-buffer-size=10000 Number of envelope to be buffered
--events="LogMessage" Comma separated list of events you would
like. Valid options are ContainerMetric,
CounterEvent, Error, HttpStartStop,
LogMessage, ValueMetric
--enable-stats-server Will enable stats server on 8080
--boltdb-path="my.db" Bolt Database path
--cc-pull-time=60s CloudController Polling time in sec
--cc-rps=50 CloudController Polling request by second
--extra-fields="" Extra fields you want to annotate your
events with, example:
'--extra-fields=env:dev,something:other
--orgs="" Forwarded on the app logs from theses
organisations' example: --orgs=org1,org2
--mode-prof="" Enable profiling mode, one of [cpu, mem,
block]
--path-prof="" Set the Path to write profiling file
--log-formatter-type=LOG-FORMATTER-TYPE
Log formatter type to use. Valid options
are text, json, json-cee. If none
provided, defaults to json.
--cert-pem-syslog="" Certificate Pem file
--ignore-missing-apps Enable throttling on cache lookup for
missing apps
--version Show application version.
** !!! --events Please use --help to get last updated event.
Since v3 firehose-to-syslog support TLS syslog --cert-pem-syslog using PEM encoded cert file.
Please refer to https://github.com/RackSec/srslog/blob/master/script/gen-certs.py
for Cert generation.
rsyslog supports parsing JSON log messages throught its mmjsonparse module. This module expects a parsable JSON log message to be prepended with the value @cee:.
For LOG-FORMATTER-TYPE, using json-cee will yield the same result as using json but the JSON sent will have @cee: prepended to it. The json-cee formatter type also ensures that a RFC3164 compatible log message is sent, which was found to be required by rsyslog when using the mmjsonparse module.
See the dropsonde protocol documentation for details on what data is sent as part of each event.
We use boltdb for caching application name, org and space name.
We have 3 caching strategies:
- Pull all application data on start.
- Pull application data if not cached yet.
- Pull all application data every "cc-pull-time".
# Setup repo
go get github.com/cloudfoundry-community/firehose-to-syslog
cd $GOPATH/src/github.com/cloudfoundry-community/firehose-to-syslog
# Test
make test
# Build binary
go build
To enable CPU Profiling you just need to add the profiling path ex --mode-prof=cpu
Run your program for some time and after that you can use the pprof tool
go tool pprof YOUR_EXECUTABLE cpu.pprof
