HTTP CRITICAL: Status line output matched pattern not found

[kaushalshriyan]

Hi,

I'm using check_http plugin for nagios alerting. Till now, i was using the http status code to raise the alerts.
but recently, i was asked to verify some json http response along with the http status code where i need to modify my nrpe.cfg file.

check_http -H xxxxx.xxx -S -k 'Host: xxxx.xxx' -k 'Test: Test' -p 443 -j POST -T 'application/x-www-form-urlencoded' -P 'name:xyz' -a 'xyz123:123xyz' -u '/a/b/c?Redirect_URL=https://www.google.com/' -e 'HTTP/1.1 200 OK' -f follow -l -r 'operator:t-mobile'


Here the issue i face is, i am able to detect the status code, but i am not able to match the regex pattern which i get in http response(JSON)

Sample response suing the curl is :

{
"a": 12332423452,
"response": {
"test": "test1",
"abc": "abc",
"operator": "t-mobile",
"country": "india",
"currency": "Rupee",
},
"id": "419E2BD429C1C8E7459911268513C9B5EE3C2AD0E4BE5C528952D6A89DE8D6E2C6623494ADA60C1AAF0462C30CB71874D86D1CFEBEBE26E59DA9654B5ABC9E0916CCD5D88097163AC9ED87B43E00549A86C818700C5B3E561CF0AB9ADC0AB7FA9C072175B4495034CF7F3313CA8D154DA086F9B86EFF3212"
}


I even tried using the -s flag where we can use expected string, but the id field in the response will keep changing, which made me to check for regex.

Output: HTTP CRITICAL: Status line output matched "HTTP/1.1 200 OK" - HTTP/1.1 200 OK - pattern not found - 9987 bytes in 0.938 second response time |time=0.938158s;;;0.000000 size=9987B;;;0

Any help will be highly appreciated. Thanks in Advance.

Best Regards,

Does this work for you?

Code: Select all

check_http -H xxxxx.xxx -S -k 'Host: xxxx.xxx' -k 'Test: Test' -p 443 -j POST -T 'application/x-www-form-urlencoded' -P 'name:xyz' -a 'xyz123:123xyz' -u '/a/b/c?Redirect_URL=https://www.google.com/' -e 'HTTP/1.1 200 OK' -f follow -l -s '"operator": "t-mobile"'

Hi ssax,

It does not work. The http response code in JSON format are as below

Code: Select all

{"ttl":1541639699,"response":{"client_id":"x-test123","client_secret":"x-testsecret123","serving_operator":"t-mobile","country":"US","currency":"Dollar","apis":{"operatorid":{"link":[{"href":"http://us.gateway.wso2tel.com/authorize/v1/t-mobile/oauth2/authorize","rel":"authorization"},{"href":"https://us.gateway.wso2tel.com/token/v1/t-mobile/oauth2/token","rel":"token"},{"href":"https://us.mconnect.wso2tel.com/oauth2/userinfo?schema=openid","rel":"userinfo"}]}}},"subscriber_id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}

Please suggest further.

What about this one:

Code: Select all

check_http -H xxxxx.xxx -S -k 'Host: xxxx.xxx' -k 'Test: Test' -p 443 -j POST -T 'application/x-www-form-urlencoded' -P 'name:xyz' -a 'xyz123:123xyz' -u '/a/b/c?Redirect_URL=https://www.google.com/' -e 'HTTP/1.1 200 OK' -f follow -l -s 'operator":"t-mobile'
