Nagios Support Forum

Hi,

My http url is giving JSON response. I would like to parse and save the value.Is Nagios Core providing the feature?

Thanks

You would need to find (or create) a plugin to do this. This might be a good starting point:

I have script to parse and save the JSON. Now I'm getting JSON response from check_http plugin. How to parse the JSON response which is retrieved from check_http plugin output.

You could use the string match ( -s, --string=STRING ) or regex ( -r, --regex, --ereg=STRING ) to parse the output to a state.

Can't understand .

-s, --string=STRING
String to expect in the content

-R, --eregi=STRING
Search page for case-insensitive regex STRING

How this parameter will help to retrieve and save the value from JSON response

If you want to retrieve and save the json, just use wget or curl. What is the usage case for this?

Here is my scenario.

I'm testing my APIs using check_http plugin. First API will have token in JSON response. I need to parse the token and save it. Then I need to use this token as a parameter for all other APIs. Check_http plugin's verbose command his giving JSON response.

Thanks

This request will require a custom script. You will need to fetch the json, parse it, and then save it to a file. Another script would then wrap check_http to use the new parameter from the previous script. This is out of scope for our support, so my suggestion would be to create the scripts, do some troubleshooting, and then post here when you need help.

Hi,

I'm using check_http plugin to check my APIs. Verbose command is giving the response. I want to save the response. Is there any possibility yo save the response?

Sure, write a wrapper script that uses the check_http command, and redirects the output to a flat file. This is not something that core will do on its own, or the check_http plugin, it will need to be custom created.
