Nagios Support Forum

Hi Team,

We have a requirement to monitor the Webserver log files on servers for a particular string with a fixed frequency of polling for 24x7 throughout the year.
Please can you let us know if this can be enabled using Nagios tool to highlight/alert the team if the string is found.

In order to answer this question, you will need to tell us if you are want to check for this string in a logfile on Linux or a Windows host.

Also, in addition to WillemDH's questions, are you looking to have near-real-time alerting (passive checks) or to have the XI server reach out on an interval to check (active checks).

Thank you

Hi Team,

We want to implement this for a windows remote host.

There is a folder containing number of files, files are generated regularly in this folder as these are log files, file name will be consisting the date and time specifying at what particular time it was created. Nagios needs to fetch the recent file from the folder.

Nagios should check that file after some time interval (say 5mins) and fetch the string in the file , if the string is found then alert needs should be send.

You should be able to achieve your goal by using the "check_log3" with "NSClient++".

Hope this helps.

Hi Team,

Thanks for the document explaining how to enable NRPE in NSClient++.

But let me know how to detect a string in a file for windows host.

Now you need to go back to what @lmiltchev suggested and use check_log3 with NSClient++

Can you let me know some other link from where I can download the "check_log3.exe" file for my windows host?
