Nagios Support Forum

Hi,
I want to create a new plugin or using an existing one to create alert in Nagios for API Monitoring for 'POST' method.

For this I already tried Nagios 'check_http' plugin to post "Json". However we are getting expected response for "Failure" case whereas Json String is not recognized for 'Success' cases. I tried using both single & double quote (' '/" ") for the POST string but that gives me the same error. I try the same thing using 'cURL' command and it gives me the expected JSON response.

Pl. find below the 'cURL' & corresponding 'check_http' command we are using now , output screenshots are also attached---
cURL command ---> curl -X POST -H "Content-Type: application/json" -d "{'catalogRefId':'9780545791342'}" http://test.com/rest/model/api/v1/atg/c ... tInventory

check_http command----> ./check_http -H test.com -u /rest/model/api/v1/atg/commerce/inventory/InventoryActor/getInventory -T "Content-Type:application/json" -j 'POST' --post="{'catalogRefId':'9780545791342'}" -v

The content-type header isn't formatted correctly. Try:

./check_http -H test.com -u /rest/model/api/v1/atg/commerce/inventory/InventoryActor/getInventory -T "application/json" -j 'POST' --post="{'catalogRefId':'9780545791342'}" -v

Please provide the output of both commands if this doesn't help resolve the problem.

Hi cdienger,
Many many thanks for your early response. Following your suggestion I am getting success for those cases where 'post' required only one parameter and corresponding value(e.g post='{"skuId":"9780155061392"}), however for those cases where it's required multiple parameter and value(e.g --post="{'login':'bnmonitoring01\@gmail.com','password':'Bn\@123'}").
Below are commands I am using for single & multiple parameter cases, I also uploading the output for both cases for your reference ---

Single parameter case :---

./check_http -H bn-api.bn-web.com -u /rest/model/api/v1/atg/commerce/pricing/PricingActor/skuPrices -T "application/json" -j 'POST' --post='{"skuId":"9780155061392"}' -v

Multiple Parameter case :----

./check_http -H test.com -u /rest/model/api/v1/atg/userprofiling/ProfileActor/login -T "application/json" -j 'POST' --post="{'login':'bnmonitoring01\@gmail.com','password':'Bn\@123'}" -v

Once again thanks for your help. Appreciating your early response.

The \ to escape @ isn't necessary. Try the following instead:

./check_http -H test.com -u /rest/model/api/v1/atg/userprofiling/ProfileActor/login -T "application/json" -j 'POST' --post="{'login':'bnmonitoring01@gmail.com','password':'Bn@123'}" -v

Hi cdienger,
Thanks for your prompt reply.
I tried the command without escape character '\' also, however same result is coming.

Please help.

Can you provide us with the output of the command please?

./check_http -H test.com -u /rest/model/api/v1/atg/userprofiling/ProfileActor/login -T "application/json" -j 'POST' --post="{'login':'bnmonitoring01@gmail.com','password':'Bn@123'}" -v

Hi,
Thanks for your reply. Please find attached the output(login.txt) of below command for login API. Instead of '200', return code is coming '302', login success message is also not coming. However if we are using below URL, we are getting 'login successful' message ---

Nagios Command for Login ---

./check_http -H test.com -u /rest/model/api/v1/atg/userprofiling/ProfileActor/login -T "application/json" -j 'POST' --post="{'login':'bnmonitoring01@gmail.com','password':'Bn@123'}" -v

Login URL ---------------------

http://test.com/rest/model/api/v1/atg/u ... ord=Bn@123

The 302 is a redirect. You can have the check follow the redirect with:

./check_http -H test.com -u /rest/model/api/v1/atg/userprofiling/ProfileActor/login -T "application/json" -j 'POST' --post="{'login':'bnmonitoring01@gmail.com','password':'Bn@123'}" -v -f follow

Hi cdienger,
Many many thanks for your excellent help. after adding the -f followup, command is working as expected.

Appreciate all your extended help.

Looking forward for your future help/suggestion.

Glad to help
