 Description   

Description:

ipmitool shows  IPMI "CPU 2 Temp" sensor exist on this server and return value but zabbix server can't see it.
After run server with DebugLevel=4 and grep zabbix server logs for "CPU " I can see only discovered "CPU 1 Temp" sensor (despite the detection of other sensors for CPU2).**

I suspect more than listed above zabbix server version has is affected this issue

Steps to reproduce:

  1. Set StartIPMIPollers=3 in zabbix_server.conf and restart server.
  2. Prepare IBM x3550 M4 server's BMC (IMM2 in this case) to accept IPMI requests.
  3. Add host with x3650 M4 IMM2 address as IPMI interface and correct IPMI configuration.
  4. Create IPMI item with "IPMI Sensor" value as "CPU 2 Temp".

Result:
Zabbix says "sensor or control CPU 2 Temp@[192.168.yyy.xxx]:623 does not exist" (see attachment).

Expected:
Zabbix server show "CPU 2 Temp" value like it does for "CPU 1 Temp". (Tested server has CPU on botch sockets).

Thanks

Hi,
As per our documentation - have you tried adding a "0" at the end of the sensor name?

Hi Arturs,

Yes, I tried but server sayed the same (sensor does not exist).
I created item for the same host with "IPMI Sensor" value as "CPU 1 Temp" and it's works fine. I can see values returned by this item.

Unfortunately, we cannot reproduce the issue without the additional details we've requested earlier. With that in mind, we are closing the case. Please feel free to reopen the ticket if the problem persists.
