Custom Macro/Variable Limitation

[avezinaATetl]

Hi,

I'm trying to use macro/variable to sets some urls/fqdn to check.

I am using the variable name : FQDN_Product_Service with a value of "devapi.example.org"
And the check command check_http : Check_API_Health!$_HOSTFQDN_PRO_SVC$!http://$_HOSTFQDN_PRO_SVC$/api/Health

When I do a network capture to see what is requested, I see that http://$/api/Health is requested.

Is there some limitation to the length or character choices in the variables? I already discovered that Nagios don't want hyphen '-' within variable names.

Custom variables should start with an underscore

Code: Select all

_FQDN_Product_Service     devapi.example.org

Hi Scott, thank you for your reply.

Yes, custom variable starts with an underscore. I forgot about it in my post, but I do have them in my configs.

While I do some more test to expand my question, can you answer this question : Is there a character limitation (hyphens, underscore, other symbols) or limit for custom variables?

Not specifically, other that what is posted here
https://assets.nagios.com/downloads/nag ... tvars.html

However I just realized you are adding them in the $ARGn$ fields, and honestly, I don't think that will work

You will likely need to make a new command definition and pass the $_HOSTFQDN_PRO_SVC$ variable where you have $ARG1$, etc.

ALSO, I just saw this
you said the variables are named

Code: Select all

_FQDN_Product_Service

but you are referencing

Code: Select all

$_HOSTFQDN_PRO_SVC$

instead of

Code: Select all

$_HOSTFQDN_PRODUCT_SERVICE$

Thank you again.

The variables are not the same in my initial post because I used placeholders and didn't use them the same way for the post.

After checking everything again, I had some typo at multiple places. Fixed them.

I think my problem was caused by not using all upercase in my variables names and places where I use them.

Here is my check_command that works:
$USER1$/check_http -I $HOSTADDRESS$ -e '200 OK' -H $_HOSTFQDN_ENROUTE-ROUTE$ -u https://$_HOSTFQDN_ENROUTE-ROUTE$/api/Health -S

Great! May we mark this resolved?
