Custom LLD issue

[Sean35]

Hi all,

I'm building a template for monitoring a Pure Storage Array and I'm having some issues.

I've built a number of similar templates using LLD successfully, so I really have tried hard to get this working.

The script I'm using is view-able here: http://pastebin.com/u5jTBgdM

It would be executed as follows to discover temperature metrics:

PureStorageMonitoring.py [IP_ADDRESS] [API_TOKEN] discoverytemp

I know the script works as I've tested it manually, also confirmed the JSON on http://jsonlint.com/:

{"data": [{"NAME": "CT0.TMP0", "ID": "CT0.TMP0"}, {"NAME": "CT0.TMP1", "ID": "CT0.TMP1"}, {"NAME": "CT0.TMP12", "ID": "CT0.TMP12"}, {"NAME": "CT0.TMP14", "ID": "CT0.TMP14"},.........{"NAME": "CT1.TMP8", "ID": "CT1.TMP8"}]}

The Discovery item is as follows:

PureStorageMonitoring.py[{HOST.CONN},{$APITOKEN},"discoverytemp"]

{$APITOKEN} is a macro within the host.

I have one Item prototype called:

Temperature for {#NAME}

With a key of:

PureStorageMonitoring.py[{HOST.CONN},{$APITOKEN},"temperature",{#ID}]

If I manually add a regular item with an ID which I know exists, for example:

PureStorageMonitoring.py[{HOST.CONN},{$APITOKEN},"temperature",CT1.TMP8]

This item works correctly proving the API token etc.

But for some reason discovery is failing and items are not created:

Cannot create item: item with the same key "PureStorageMonitoring.py[{HOST.CONN},{$APITOKEN},"temperature",{#ID}]" already exists.
Cannot create item: item with the same key "PureStorageMonitoring.py[{HOST.CONN},{$APITOKEN},"temperature",{#ID}]" already exists.
Cannot create item: item with the same key "PureStorageMonitoring.py[{HOST.CONN},{$APITOKEN},"temperature",{#ID}]" already exists.

I've increased Discovery debug to 5 but there is nothing relating to this item which shows up.

Any advice on where to look next (unless it's obvious what I'm doing wrong!)?

Thanks in advance,
Sean

Your JSON needs to contain whole macro names. Like

"{#FOO}": "bar"

instead of just

"FOO": "bar"

Fix your script and everything should be fine.

Glebs,

You're completely right, thank you so much.

All working now.
