thank you for your comment,<div>but, I think i already configured like you just said.</div><div>actually A1,A2 is not a server but it is our access switch i mean</div><div>there are many servers under A1, A2</div><div><br> </div><div>let me describe my environment again,</div><div><br></div><div>BB1->A1->server1, server2, nagios1(center), nagios2(for servers under A1), nagios3(for servers under A2), nagios4(just for switch monitoring)</div> <div><br></div><div>BB1->A2->server3, server4...</div><div><br></div><div>my central server (nagios1) has all objects definition(BB1,A1,A2,server1,server2,server3....etc)</div><div>and then nagios2 has only 2 defined servers which is server1 and server2</div> <div>nagios3 has server3, server4</div><div><br></div><div>if I start nagios daemon on nagios3, it shows me an error like "there's no parent definition for server3"</div><div>because parent for server3 is A2 and parent for A2 is BB1.</div> <div>and I didn't put config for A2 and BB1 to nagios3.</div><div><br></div><div>I have no problem when i starting nagios in my central server, </div><div>cuz central server has all configurations of my servers and switches</div> <div><br></div><div>but distributed nagios server which is nagios3 won't start.</div><div><br></div><div>am I doing right or is there a misunderstanding to config nagios properly?</div><div><br></div><div><br><div class="gmail_quote"> On Wed, Feb 24, 2010 at 7:19 PM, Assaf Flatto <span dir="ltr"><<a href="mailto:nagios@flatto.net">nagios@flatto.net</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> <div><div></div><div class="h5">HyunSung Jang wrote:<br> > hello.<br> ><br> > i just finished setting up nagios as distributed monitoring and i<br> > found a problem.<br> > we have a backbone switch called BB1.<br> > and we have 2 access switch called A1, A2 which uses uplink to BB1<br> > so this makes both A1,A2 have its parent BB1<br> ><br> > and then i prepared 4 dedicated servers for nagios,<br> > first server for central server,<br> > second server for servers under A1,<br> > third server for servers under A2,<br> > fourth server for our switches BB1,A1,A2<br> ><br> > in this environment, how can i define parent/child relationship in<br> > distribute nagios server??<br> > i read nagios manual that says "only those services and hosts which<br> > are being monitored directly by the distributed server are defined in<br> > the object configuration file"<br> ><br> > i want keep all configuration file for switches only fourth server<br> > which is for dedicated switch monitoring.<br> ><br> > when i try to start nagios in second and thrid server, it shows error<br> > like "there is no BB1 parent define in configuration"<br> ><br> > thanks for your help.<br> ><br> </div></div>Hello<br> <br> I know it is bad to assume things , but i will take it that you have<br> both server A1 and A2 transfer the results to the central nagios .<br> <br> What you must remember and is clearly stated in the docs is that the<br> definitions of the remote server has to also be on the central server -<br> they do not however need to be a duplicate on the remote server , that<br> being said , the Parnet/child relation ship can and should be defined on<br> the central server for the whole network , BB1-->A1 -> hosts . while on<br> each remote host you define the parent/child for only the relevant hosts<br> that the host is checking .<br> so if host A1 id down stream from BB1 - it is not defined on A1 , but on<br> the central server only ( it is also a good idea to have active<br> monitoring of BB1 on the central so it will be able to show real<br> time UP/Unknown statuses ).<br> <br> Hope this helps.<br> <br> Assaf<br> <br> ------------------------------------------------------------------------------<br> Download Intel® Parallel Studio Eval<br> Try the new software tools for yourself.
