Hi
Check mk 2.0.0p23 raw here and i am trying to detect APs as services on a cisco WLC 9800 (appliance)
Even if i read it should be implemented within this version, i am not able to detect connected APs and wifi clients.
I tried to copy this file
in /opt/omd/sites/sitename/local/lib/python3/cmk/base/plugins/agent_based
without any success.
I believe i am missing something could you help please?
Thabnk you very much!
Hi @ercole77 and welcome to the check**mk* community.
Could you please provide a snmpwalk of the oid .1.3.6.1.4.1.9.1.?
Please note, my addition was for the WLC _C_9800
Thank you for your feedback and help!
Unluckily snmpwalk -v 1 -c public ip .1.3.6.1.4.1.9.1 returns nothing
Did you try a V2 walk instead of V1. V1 will not handle 64-Bit counters.
Regards,
Christian
Hi Christian
snmpwalk -v 2c -c public IP .1.3.6.1.4.1.9.1 returns
SNMPv2-SMI::enterprises.9.1 = No Such Object available on this agent at this OID
@tosch you are shure that .1.3.6.1.4.1.9.1 is the correct OID to check? After a qiuck look in the check files it looks like the content of .1.3.6.1.2.1.1.2.0 (sysObjectID) is the importent part for the check to discover a WLC.
@ercole77 can you check this OID please?
@thl-cmk thank you for your help
here is the result of snmpwalk -v2c -c public IP .1.3.6.1.2.1.1.2.0
SNMPv2-MIB::sysObjectID.0 = OID: SNMPv2-SMI::enterprises.9.1.2861
@thl-cmk @tosch
i have found the AP entries
snmpwalk -v2c -c public 10.243.252.10 .1.3.6.1.4.1.9.9.513.1.1.1.1.5

ok this is a Cisco WLC C9800LFK9…
for now you could extend the WLC check with the content (1.3.6.1.4.1.9.1.2861) of the sysObjectID like in the werk you where refering to. The plugin should then discover your WLC as well.
for everyone how is interested this is the list of Cisco WLCs the check will discover right now:
".1.3.6.1.4.1.14179.1.1.4.3", # productGroup3
".1.3.6.1.4.1.9.1.1069", # cisco5500Wlc

".1.3.6.1.4.1.9.1.2860", # ciscoC9800LCK9
@tribe: maybe you want to add these comments to the check 
and this devices are still missing from the list:
".1.3.6.1.4.1.9.1.2861", # ciscoC9800LFK9
".1.3.6.1.4.1.9.1.2669", # ciscoC980080K9

cisco_wlc.py (5.0 KB)
@thl-cmk no luck, this is the cisco_wlc.py file i am using copied in
/opt/omd/sites/sitename/local/lib/python3/cmk/base/plugins/agent_based/
i believe i am missing something, excuse me im not familiar with SNMP
your change looks ok. But the check looks under .1.3.6.1.4.1.14179.2.2.1.1 for it’s data… so you need to check if your device delivers the AP name from .1.3.6.1.4.1.14179.2.2.1.1.3 (bsnAPEntry) and the AP state from .1.3.6.1.4.1.14179.2.2.1.1.6 (bsnAPOperationStatus)
i believe yes,
i see
.1.3.6.1.4.1.14179.2.2.1.1.3.28.209.224.121.98.32 = STRING: “AP-NAME”
and
.1.3.6.1.4.1.14179.2.2.1.1.6.28.209.224.121.98.32 = INTEGER: 1
is there any particular activity i am supposed to do after i modify the cisco_wlc.py script besides a full scan of the host?
looks ok. You can try a cmk --detect-sections cisco_wlc -vII YOURHOST. This will skip the detect function and just tryes to fetch the data and if OK add the services.
@thl-cmk thanks
OMD[site]:~$ cmk --detect-sections cisco_wlc -vII wlc-controller1
Error in agent based plugin cisco_wlc: Wrong type annotation: cluster sections must be of type Mapping[str, Optional[<NodeSection>]]
Discovering services and host labels on: wlc-controller1
wlc-controller1:
looks like the check on your system has some coding issues 
If you have a look at the actual version on github you can see in line 115 the key word Optional, this is missing in your check.
def cluster_check_cisco_wlc(
item: str,
params: Mapping[str, Any],
section: Mapping[str, Optional[Section]],
) -> CheckResult:
if you add this to your check, you also need to adjust the import statement in line 36
from typing import Any, Dict, List, Mapping, Optional
@thl-cmk thank you a lot
i have substituted the file with the original plus your additional line
it is weird now i can detect the AP with
cmk --detect-sections cisco_wlc -vII wlc-controller1
Discovering services and host labels on: wlc-controller1
wlc-controller1:
but when i edit the service configuration in the GUI i see the APs all vanished.
its like the command is able to use the plugin but the GUI doesnt
EDIT: i was missing a section now it works!!!
Next step…how can add the the clients for SSIDs ?
