Re: [Nagios-users] Nagios Plugin Log Pattern Notification
Which OS ? Linux has a few. Logwatch and Swatch come to mind. I think there is more than one version of logwatch.

Re: [Nagios-users] Confusion on nrpe
HiJacking a thread? What are you talking about? If I had maintained someone's subject but changed the content, that is hijacking a thread. Merely hitting 'reply' and deleting the subject and replacing it, deleting the body and writing my own does not seem to me, to qualify as hijacking a thread. That is creating a new thread, by changing the subject and body. Or am I completely missing something? I do sort by thread on my machine and my emails are perfectly sorted. Perhaps you should start sorting my subject instead of X-header or whatever you are threading on now. I would love to have learned something about what you are talking about, but so far, you haven't explained a thing, merely complained. If I want it further threaded, then it is grouped by the subject. What on earth are you threading by (and what amazing email client are you using) that causes my repurposing an email the way I do to cause a problem, X-Header attributes? If you have a problem with a persons actions, You should have taken the reply immediately offline, and not sent it to the group. You should also explain why doing what I do causes a problem, and not assume that what I do is intentional to cause a problem. Maybe I am not born with all knowledge and experience in all things mailing list known to man, as you apparently are. Some people try to teach and share knowledge. Since you insist, I will continue here to we can all learn from your complaint and eventual (hopefully) explanation as to how my process causes problems. BTW, You are the first person ever to have mentioned that doing it this way is causing a problem. I'll keep the thread here instead of taking it offline. This way if anyone else does what I do, we can all learn why this causes a problem. Maybe, we can get the owner of the mailing list to place a link or footer in each posting that says what address to send emails to. Then people like I who don't know, could just copy and paste that email address into new emails instead of hitting reply and changing subject and body and letting it fly. That is a fairly common thing in newsgroups postings, probably for this exact reason. I eagerly await your instructional and helpful reply. --Bruce D.

In the standard configuration, Nagios runs check_nrpe on the central server just as it runs check_http and anything else; check_nrpe makes a connection to the nrpe-server on a remote machine; that remote machine runs the check it's configured to run, and reports the result back over the connection to the central server. I have a configuration that goes a bit beyond this. Server A is running Nagios; server B is directly accessible; server C is on a private network behind server B. In this case, there are several extra checks associated with server C that actually hit server B's NRPE instance, then fall through a second NRPE call to server C. -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
