I have used the NagiosXI's wizard for Nagios Logserver to configure on Nagios XI an alert that I defined a while ago on Nagios LS.

Right now, the alert on Nagios LS is green (no match).

the query string on Nagios LS is :

Code: Select all

+SourceModuleName:HL7Processor +ERROR

Which means give me the records containing "ERROR" AND that are from the source "HL7Processor".

The wizard on Nagios XI generated this command :

Code: Select all

check_nagioslogserver.php --url='http://vipnagioslog/nagioslogserver/' --apikey='20f34782f619f1620246f87911573e9f77d26b78' --minutes='10' --warn='1' --crit='5' --query='{"query":{"filtered":{"query":{"bool":{"should":[{"query_string":{"query":"+SourceModuleName:HL7Processor +ERROR"}}]}},"filter":{"bool":{"must":[{"range":{"@timestamp":{"from":1430922548745,"to":1431008948746}}}]}}}}}'

The problem is that when this command check is fired, the "AND" logic seems to becom an "OR" logic.

It indeeds find about 1300 matching records, while it should report 0.

And if I launch the command with only "+SourceModuleName:HL7Processor" and then only "+ERROR", I respectively get about 1000 and 300 matching records.

So, the bottom line is that the "AND" logic is replaced by "OR" when using that command. Is there any kind of syntax I should use to correct that?

Try formatting your Lucene syntax in the following way:

Code: Select all

SourceModuleName:HL7Processor AND ERROR

You might add the '+' characters if they are indeed part of the string. The above worked for me on Nagios Log Server version 1.4.0 - let me know if it works for you. Thanks!

Lemme clean this up a bit:

Code: Select all

check_nagioslogserver.php --url='http://vipnagioslog/nagioslogserver/' --apikey='20f34782f619f1620246f87911573e9f77d26b78' --minutes='10' --warn='1' --crit='5' --query='
{
  "query":{
    "filtered":{
      "query":{
        "bool":{
          "should":[
            {
              "query_string":{
                "query":"+SourceModuleName:HL7Processor +ERROR"
              }
            }
          ]
        }
      },
      "filter":{
        "bool":{
          "must":[
            {
              "range":{
                "@timestamp":{
                  "from":1430922548745,
                  "to":1431008948746
                }
              }
            }
          ]
        }
      }
    }
  }
}'

If you change the "should" to a "must" does that work? Or are you saying that the OR is taking place like "SourceModuleName:HL7Processor" OR "ERROR"? If that's the case, try keeping it as "should" and change the query to "SourceModuleName:HL7Processor" AND "ERROR".

Edit: Bah, Jesse beat me to it :)
