What specific java app are you trying to monitor? Tomcat, JMX, etc? And what metrics are you looking to get out of these checks?

First thank you for your reply.
My java application is completely Restfull application.i want monitor all application logs.for logging purpose I am using log4j and all logs stored in sqlserver.Now my question is how to monitor these logs.


Thank you once again.

Okay, so you don't actually want to monitor a Java App like you said, directly. Sounds like you will need to sculpt some sql queries to get that information. If you can also get these logs in flat files (.txt, .log, etc) you could monitor them with plugins that are already in existence. You could also use the MySQL Query wizard in XI to add those queries to your XI server as service checks.

1.) The easiest way to get a log file into Nagios Logserver is to have it as a text file and use syslog to send that off, or directly send it as a syslog message. In order to get the logs out of a database you will need to, as slansing mentioned, write a shell script (or perl, python, etc) that will query the database for this information and pass it off to Nagios.

2.) These values are from a ping check:

Code: Select all

RTA   = Round-Trip Average
PL    = Packet Loss
RTMAX = Maximum Round-Trip time
RTMIN = Minimum Round-Trip time
