v5.4.9 - low level discovery using zabbix_sender

[davama]

Hello,

I am trying to get values into my discovered items

I have a script locally on my agent that outputs the following:

[root@tamu46668 ~]# ./zabbix-lane-status.sh
{"data":[
{"{#POSLANE}":"tamu46668_lane_1_pos","{#POSLANESTA TUS}":"down"},
{"{#POSLANE}":"tamu46668_lane_2_pos","{#POSLANESTA TUS}":"offline"},
{"{#POSLANE}":"tamu46668_lane_3_pos","{#POSLANESTA TUS}":"down"},
{"{#POSLANE}":"tamu46668_lane_4_pos","{#POSLANESTA TUS}":"idle"},
{"{#POSLANE}":"tamu46668_lane_5_pos","{#POSLANESTA TUS}":"total"},
{"{#POSLANE}":"tamu46668_lane_6_pos","{#POSLANESTA TUS}":"offline"},
{"{#POSLANE}":"tamu46668_lane_7_pos","{#POSLANESTA TUS}":"offline"},
{"{#POSLANE}":"tamu46668_lane_8_pos","{#POSLANESTA TUS}":"down"},
{"{#POSLANE}":"tamu46668_lane_9_pos","{#POSLANESTA TUS}":"offline"},
{"{#POSLANE}":"tamu46668_lane_10_pos","{#POSLANEST ATUS}":"offline"},
{"{#POSLANE}":"tamu46668_lane_11_pos","{#POSLANEST ATUS}":"offline"},
{"{#POSLANE}":"tamu46668_lane_12_pos","{#POSLANEST ATUS}":"idle"},
{"{#POSLANE}":"tamu46668_lane_13_pos","{#POSLANEST ATUS}":"idle"},
{"{#POSLANE}":"tamu46668_lane_14_pos","{#POSLANEST ATUS}":"down"},
{"{#POSLANE}":"tamu46668_lane_15_pos","{#POSLANEST ATUS}":"idle"},
{"{#POSLANE}":"tamu46668_lane_16_pos","{#POSLANEST ATUS}":"offline"},
{"{#PRINTERLANE}":"tamu46668_lane_1_printer","{#PRINTERLANESTATUS}":"offline"},
{"{#PRINTERLANE}":"tamu46668_lane_2_printer","{#PRINTERLANESTATUS}":"offline"},
{"{#PRINTERLANE}":"tamu46668_lane_3_printer","{#PRINTERLANESTATUS}":"offline"},
{"{#PRINTERLANE}":"tamu46668_lane_4_printer","{#PRINTERLANESTATUS}":"online"},
{"{#PRINTERLANE}":"tamu46668_lane_5_printer","{#PRINTERLANESTATUS}":"online"},
{"{#PRINTERLANE}":"tamu46668_lane_6_printer","{#PRINTERLANESTATUS}":"offline"},
{"{#PRINTERLANE}":"tamu46668_lane_7_printer","{#PRINTERLANESTATUS}":"offline"},
{"{#PRINTERLANE}":"tamu46668_lane_8_printer","{#PRINTERLANESTATUS}":"offline"},
{"{#PRINTERLANE}":"tamu46668_lane_9_printer","{#PRINTERLANESTATUS}":"offline"},
{"{#PRINTERLANE}":"tamu46668_lane_10_printer","{#PRINTERLANESTATUS}":"offline"},
{"{#PRINTERLANE}":"tamu46668_lane_11_printer","{#PRINTERLANESTATUS}":"offline"},
{"{#PRINTERLANE}":"tamu46668_lane_12_printer","{#PRINTERLANESTATUS}":"online"},
{"{#PRINTERLANE}":"tamu46668_lane_13_printer","{#PRINTERLANESTATUS}":"online"},
{"{#PRINTERLANE}":"tamu46668_lane_14_printer","{#PRINTERLANESTATUS}":"offline"},
{"{#PRINTERLANE}":"tamu46668_lane_15_printer","{#PRINTERLANESTATUS}":"online"},
{"{#PRINTERLANE}":"tamu46668_lane_16_printer","{#PRINTERLANESTATUS}":"offline"}
]}

inside /etc/zabbix/zabbix_agentd.conf we have:

UserParameter=jbrain.pos.lane.discovery,/usr/local/bin/zabbix-lane-status.sh

My zabbix template has the discovery item as so:


Along with the item prototype as so:



This as shown in the 1st screenshot creates the discovered lanes.

I want the value of `#POSLANESTATUS` to be there but not sure what I'm doing wrong. In other words, I want pos_lane_X with a value of pos_lane_X_status

Im certain it has to do with my zabbix template setup but not sure what...

any input is much appreciated!!

Thank you,
Dave

Update:

Happy to report that got it working!!!

So changes and final settings that are working for me now:

output of the script no just outputs a json list.

[root@apcd0995-ng ~]# zabbix_agentd -t jbrain.lane.get.item
zabbix_agentd [16441]: Warning: both HostMetadata and HostMetadataItem defined, using [Jbrain-old-7]
jbrain.lane.get.item [t|[{"pos_status":"sign_on","pos_lane":"apcd0995-ng_lane_1_pos"},{"printer_lane":"apcd0995-ng_lane_1_printer","printer_status":"offline"}]]

adjusted my item prototype to below:

preprocessing looks similar to the link reference I was given:

$.[?(@.pos_lane=='{#POSLANE}')].pos_status.first()

And here is my trigger prototype which works:






Awesome!

Issue you have is, that those items you create are "trapper items", you should send data to them one by one (or from script /input file etc). But you are not doing this. Just running this discovery doesn't do it.

Change your discovery into normal item (lets call it master here). It will return data from that userparameter. Then add discovery as "dependent item", depending on your master item. Your discovery should have declarations for LLD macros. what you will use in item prototypes etc (you probably have it as your items are created)...Your item prototype should be also dependent item, depending on same master item. Little preprocessing to point them to correct value. something along
Each time your master receives new values, discovery runs over it and creates/obsoletes items, second time new set of values arrive, you will get values to discovered items.

Concept is same as here https://www.zabbix.com/documentation...ed_filesystems

Thank you for the reply!

I attempted to mimic the link you sent.

So now my script that runs locally on the agent outputs the below:

My userparameter is now:

My master key: jbrain.lane.get.item


My discovery rule: key=jbrain.lane.discovery


My LLD Macros:



my item prototype(s):


Along with the preprocessing for this item prototype:



When I query the item with zabbix_agent on the agent itself I get the below:

But now I don't see any data in "Latest Data" for this agent...

Im sure it's something simple... unless I misconfigured....

Any input is much appreciated!!

Thank you,

Update:

was able to get discovery items!!

still missing the `value` field though but progress!

what I did:

I change the output of my script to compact the json output.

now it looks like so

[root@tamu46668 zabbix]# zabbix_agentd -t jbrain.lane.get.item

I don't see any values under the values column. Am I missing something??

Gonna continue and try to create a trigger and see where that goes.
