LLD: use {#MACROS} as "IPMI sensor" value

[Lufa]

Hello!

Zabbix 2.0.2, running Ubuntu 12.10.

I have a LL Discovery rule for discovering IPMI sensors, using a custom script.

A corresponding "Item prototype" (type-IMPI) is created. All items has been created successfully, I can see it in the Host's items.

"IPMI sensor" value for IMPI-item should be "variable" (different values for different IMPI-sensors).

So I was trying to use my custom macros for IPMI-item: {#SENSOR_ID}.

#JSON
{'data': [{'{#SENSOR_ID}': 'Pwr Unit Status', '{#SENSOR_NAME}': 'Pwr_Unit_Status'} ... ]}

But! it seems like Zabbix does not allow to use the LLD-macros for "IPMI sensor" field. Because I got the following errors in the logs:

sensor or control {#SENSOR_ID}@[192.168.252.206]:623 does not exist

Other macros, used in "Item name" and "Item key" was applied successfully (converted to real data), only "IMPI sensor" remains in "raw macros" value ("{#SENSOR_ID}").

So. Is there a way to use LLD-marcos for "IPMI sensor" in the "Item prototype" for "IPMI agent" type?

Thank you!

P.S.
Please look at the screenshots for better understanding.

P.P.S.
{#SENSOR_ID} exist for sure, because I was trying to use it as a Item name.

Very interesting thing! Could you share LLD template for IPMI?
Thanks.

Because of the error (described in #1 post) I have to use python script for discovery AND IPMI items data. The script was written by a friend of mine, so sorry for any syntax issues in the code.

/usr/local/etc/zabbixipmi_discovery.py:

#!/usr/local/bin/python

import os,sys

if len(sys.argv) == 3:
    if sys.argv[1] == "all":

        sensors = os.popen("sudo /usr/local/bin/ipmitool sensor").read().split("\n")
        sensor_list = {}
        data = []
        sensors_status = "ok"

        for sensor in sensors:
            sensor_param = sensor.split("|")
            if len(sensor_param) > 2:
                if  sensor_param[2].strip() != "discrete":
                    sensor_data = { "{#SENSOR_NAME}":sensor_param[0].strip()}
                    data.append(sensor_data)
                    if not (sensor_param[3].strip() in ["ok", "0x0000", "0x8000", "na"]):
                        sensors_status = "error"

        sensor_list["data"]=data
        sensor_list_json = str(sensor_list).replace("\'","\"")

        if sys.argv[2] == "list":
            print sensor_list_json
        elif sys.argv[2] == "status":
            print sensors_status

    else:
        sensor_get_cmd = "sudo /usr/local/bin/ipmitool sensor get \""+sys.argv[1]+"\""
        sensor = os.popen(sensor_get_cmd).read().split("\n")

        for sensor_param in sensor:

            if sys.argv[2] == "value":
                if sensor_param.split(":")[0].strip() == "Sensor Reading":
                    print sensor_param.split(":")[1].strip().split(" ")[0]

            if sys.argv[2] == "status":
                if sensor_param.split(":")[0].strip() == "Status":
                    print sensor_param.split(":")[1].strip()

zabbix_agentd.conf:

UserParameter=ipmi.data[*],/usr/local/etc/zabbix/externalscripts/ipmi_discovery.py "$1" "$2"

Usage in Zabbix or CLI:

# IMPI sensors discovery (JSON data):
ipmi.data["all","list"]

# Prototype item, get value:
ipmi.data[{#SENSOR_NAME},value]

# Prototype trigger, get status [OK, not OK]:
ipmi.data[{#SENSOR_NAME},status]

Tested on Zabbix 2.0.3 , FreeBSD, Intel® Server System R1304BTLSFAN server platform.

Great, thanks ! I will try to test.

Remember to install ipmitool for your system and set the correct path to it in the script.
