Hello!

Is it possible to set up an alert in Nagios Log Server if we send for example more than 2 messages in 12 hours to a specific number?

NLS could detect if the string 'Dispatched to SMSC' was seen in logs at a specific frequency, but it may get a little tricky if you're trying to do this per number. I assume 4512345678 is an example of a number - does this number change? Do you have a complete list of possible numbers? Without looking for specific numbers I don't believe what you want can be achieved in NLS.

Yes, exactly. This number 4512345678 is an example of a phone-number, and the objective is to check if many messages ('Dispatched to SMSC') are sent to this phone-number within a time-frame. Phone-numbers can be many and no real list exist per se.

Is that achievable?

Hi, Is it possible to split this message in different columns ?

I know that grok can be used. But can you help with grok filter definition for 10-15 fields for below text ?

@scv831:

Yes, I'd recommend checking out https://assets.nagios.com/downloads/nag ... ilters.pdf to see how to apply filters. And to provide an example of a grok filter parsing the first few columns I'll provide:

Code: Select all

grok {
        date {
            match => [ 'message', '%{DATE:date} %{TIME:time}\|%{DATA:test}\|%{INT:int}\|%{DATA:string}\|%{INT:int2}\|%{DATA:string2}\|%{INT:int3}%{GREEDYDATA:therestofit}' ]
        }
}

@paen08:

Is that achievable?

Unfortunately not with a dynamic number.
