sFlow doesn't export flowSampleType http
Greetings,
I have F5 BIG-IP LTM version 14.0.1 (Build 0.0.14). What I'm trying to do is to export my SLB VIP related statistics. It's referenced here in "sFlow HTTP Request sampling data types" paragraph. I configure basic sFlow collector settings in F5 GUI, run sflowtool and receive COUNTERSAMPLEs and FLOWSAMPLEs, but not with type of http. On HTTP Profile that is assigned to my SLB VIPs I have the following settings:
ltm profile http http-x-forward {
accept-xff disabled
app-service none
basic-auth-realm none
defaults-from http
encrypt-cookies none
enforcement {
known-methods { CONNECT DELETE GET HEAD LOCK OPTIONS POST PROPFIND PUT TRACE UNLOCK }
max-header-count 64
max-header-size 32768
max-requests 0
pipeline allow
truncated-redirects disabled
unknown-method allow
}
fallback-host none
fallback-status-codes none
header-erase none
header-insert none
hsts {
include-subdomains enabled
maximum-age 16070400
mode enabled
preload disabled
}
insert-xforwarded-for enabled
lws-separator none
lws-width 80
oneconnect-transformations enabled
proxy-type reverse
redirect-rewrite none
request-chunking preserve
response-chunking selective
response-headers-permitted none
server-agent-name BigIP
sflow {
poll-interval 0
poll-interval-global yes
sampling-rate 0
sampling-rate-global yes
}
via-request preserve
via-response preserve
xff-alternative-names none
}
I need to gather HTTP related statistics from my TLS-enabled VIPs, but I don't receive proper sFlow samples from F5. What could be the problem?
Thank you.
