NimbostratusMonitoring LB resopenses count for each HTTP code
Hello!
Device: big-ip ltm 1600 series. I use zabbix to monitor device. I have LB configured on it, and I have to make check of count of particular HTTP codes responses. Is it possibe?
Ex: member1_http_response_200 = x member1_http_response_400 = x member1_http_response_501 = x member1_http_response_503 = x etc..
Load Balancer configured with the device:
monitor http_%NODE%monitor {
defaults from http
recv "%STRING%"
send "GET %URL%"
}
pool %NODE% {
action on svcdown reselect
monitor all tcp
members {
%MEMBER1%:http {}
%MEMBER2%:http {}
%MEMBER3%:http {}
}
}
virtual %NODE% {
snat automap
pool %NODE%
destination %LB-VIP%:http
ip protocol tcp
}
Monitoring use SNMP to poll the device

i believe there are a couple of ways. this is an example of istats.

Alexey_02_15975Colin, do you know is it possible to publish this values to SNMP OIDs? Or may be , it is possible to share it with HTTP or some other interface (the goal is to push it to zabbix... no... to let zabbix to pull this values;) )- Alexey_02_15975Colin, we observered, that we used software version 10.2 , and this version doesn't support ISTATS. Unfortunately we can't upgrade to 11.0 version. Can you suggest another solution? Appreciate your time and thank you in advance!

unfortunately, it is not available through snmp yet. there is rfe. you may open a case to expedite the process.
ID380761 - RFE: export iStats via SNMP
in the meantime, you may try stats profile instead but stats has to be predefined (not like istats which can be created on the fly).
10.0, statistics profiles are not fully CMP compatible. Each TMM instance uses a separate instance of the statistic profile. The cumulative counts are shown in the GUI and when polled via SNMP.CMP Compatibility
