[Nagios-users] Nagios checks for failed login attempts on tomcat web-applications
Here is my question. I have nagios setup and running on a Ubuntu Server. Kernel version is: 2.6.31-22-generic i686 system. I've noticed on the access_logs several failed log in attempts from a foreign ip address to one of our web-applications. How can I make nagios do a check for failed log in attempts to my applications and send me an e-mail notification if there are more than 5 consecutive ones? Thanks for your help.

[Nagios-users] server log plugin
I need to perform the following tasks: * Demonstrated that Nagios alert is fired when certain messages are logged in the application log file on the target (remote) host * Nagios "info message" is fired when error condition is cleared. I found out "logwarn" plugin but I didn't find detailed configuration instructions for this plugin. http://exchange.nagios.org/directory/Plugins/Log-Files/check_logwarn/details And another one - "check_logfiles" - this one is described better in my opinion but referring to something called OPSVIEW that I don't have any idea about. http://www.osupport.net/2011/log-files-monitoring-with-nagios-opsview/ Did somebody have experience with well documented "check log" plugin, and could recommend one so that the functionality of the recommended plugin matches bulleted tasks in the beginning of this email that I have to accomplish?

Nagios 3.4 will be a single-threaded and event-driven application that sports an I/O-broker and vastly improved check performance. In essence, we've removed 2 fork() calls, 4 disk searches, 2 filewrites and 2 filereads from each check being performed. There's also a fixed usage of the current scheduling queue implementation which turns scheduling new checks from its current O(n) behaviour to O(1). This will provide a huge benefit for large installations, and combined with the worker process code we're currently seeing a 12-fold increase in the amount of checks Nagios can execute, but it's still too early to tell what other things are affected. The external command pipe might be a bottleneck if one uses large amounts of passive checks, for example. It's currently in late alpha, so beta releases should be available in a month or so. -- Andreas Ericsson andreas.erics...@op5.se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace. -- Better than sec?

The file objects.cache is updated quite frequently, because we often (10-20

The file is located on the ramdisk. The size of the disk is much higher
than the file size.
Is there any patch that prevents mapping of the objects.cache file in the
memory?

I usa gearman as well, nice stuff. But it lacks of authentication so it's fairly unsecure. You can use mklivestatus as a broker to notify nagios status check to 3rd part applications.
