 Description   

I've set 3 items for my server to get sensor data each 30 seconds but it Frequently changed to not supported
zabbix_server.log:
8042:20111025:103124.814 Enabling IPMI host [zproxy01]
8282:20111025:103134.311 IPMI Host [zproxy01]: first network error, wait for 15 seconds

8289:20111025:103540.094 IPMI Host [zproxy01]: another network error, wait for 15 secon

when it changed to not supported i had check with manual "ipmitool -U zabbix -H 192.168.XX.XX -I lanplus -L ADMINISTRATOR sensor"
i've got the following message:
Error in open session response message : insufficient resources for session

Error: Unable to establish IPMI v2 / RMCP+ session

also the result of "ipmitool -U zabbix -H 192.168.XX.XX -I lanplus -L ADMINISTRATOR session info all" maybe usefull (at the next possible time)

could it be that you're just overloading the target ipmi device, thus starving it of the resources ?
if so, i don't think there's anything simple zabbix could help with

Comment by hamid sfandiari [ 2011 Oct 25 ]

do you have think that 3 item for an iLo by the interval of 60 sec caused to Overloading?
it's better that zabbix get all result of sensor items from iLo in one step and gathering them in local buffer then dispatching them as they needed (because of serial aspect of data gathering from IPMI)
each date fetching need authentication and it's time consuming step

i think that the following pesudo script could solve this issue and preventing iLo from overloading

interval 1
#> ipmitool IP .... sensor > buffer
#> grep "temp 02" buffer | zabbix_send $1
#> grep "temp 03" buffer | zabbix_send $1

interval 2
#> ipmitool IP .... sensor > buffer
#> grep "temp 02" buffer | zabbix_send $1
#> grep "temp 03" buffer | zabbix_send $1

do i understand it correctly that your suggestion is to merge requests to ipmi devices if they happen to be scheduled close enough ?

as for what could overload devices, hard to say. if ipmitool returns you an error, then that's what is happening
having said that, i have seen very serious issues with hp cli tools for querying disk & array status when calling them often enough. that was definitely one thing their testing did not try at all..

Comment by hamid sfandiari [ 2011 Oct 25 ]

yes, you understood correctly

but still i am thinking that closing session after querying (don't waiting for session timeout happen on ilo side) is more effective solution
by this explanation IPMI tool is not useful way for hp in ZABBIX
(sorry for my bad English )

Similar thing happens on Fujitsu Primergu Servers.

My env:
Zabbix 1.8.10
Server Fujitsu Primergy RX300 S6

Very often I get errors in Zabbix logs and when I query the serevr with ipmitool I get:

[root@srvzabbix ~]# ipmitool -H <IP>-U admin -P admin sensor get "Power Unit"
Locating sensor record...
Get Session Challenge command failed: Out of space
Error: Unable to establish LAN session
Get Device ID command failed
Unable to open SDR for reading
Sensor data record "Power Unit" not found!

Instead of:

[root@srvzabbix ~]# ipmitool -H <IP> -U admin -P admin sensor get "Power Unit"
Locating sensor record...
Sensor ID : Power Unit (0x41)
Entity ID : 19.0
Sensor Type (Discrete): Power Unit
States Asserted : Redundancy State
[Redundancy Lost]

I am not sure we can do anything with this issue. We are looking forward to optimizing IPMI and SNMP polling by using bulk requests. It may help once implemented.

should be solved by ZBX-3243
