Re: [Nagios-users] Check_load
As far as I understand : In your example, it means that during the last 15 minutes, there was, at a said time, 0.53 processes using the cpu to do something, or waiting to be allowed to use the cpu. At this time, the other processes were not doing anything, nor waiting to do something. They were probably in idle mode, having really nothing to do... It is not because a process is in the "top" list that it is either using the cpu, or waiting for it. If I am wrong, please someone correct me. But we are indeed beyond the context of Nagios, so we should maybe continue this conversation out of the list.

As far as I understand, Parallelize check means that Nagios can multiple different service checks at the same time... So, if you have let say 100 checks. Without Parallelize check, Nagios would check the first one, wait for the result, then check the second one, wait, etc... It means that if you got checks that are kinda slow, the time to check every service can be huge... And even if the checks are fast, as soon as you got a lot of services, it will take some time anyway. > > 3.

I do not see why it should... With this configuration, nagios would, for a said service, perform one check every 5 minutes. When it detects a problem, it would do the check once every 3 minutes. And after 5 "negative" checks, it would then consider the service in a "hard state", and issue appropriate actions (ie : sending alert mails). > TIA, > sg Johan. --- Using Tomcat but need to do more?

If you want to prevent emails about services becoming unknow for some users, no matter what the service is, then edit the concerned contact definitions and remove the "u" in the service_notification_options field.

Re: [Nagios-users] per host custom macros
I don't know if you have a real use of the "host_alias", but if not, you could
maybe use this field to stock your customized definitions. You should also
change the notification scripts to send the $HOSTNAME$ and not the
$HOSTALIAS$ value
you would have something like :
host_alias $CUSTVAL1;$CUSTVAL2;$CUSTVAL3;...
Ok, it is a bit tricky, but well, it think it could work...

As far as I understand, a user can perform tasks on hosts and services that he is contact for, not hosts and services he can see. So, you could, for example, create a "read only" user using the following : - user reader is not contact for anything. In the cgi.cfg : - authorized_for_all_services=reader - authorized_for_all_hosts=reader With that, you would have an user who can see everything, but can't issue any command.

[Nagios-users] defunct process / more than one nagios "root" process...
Hello everyone. I am facing problems for a few days with my Nagios server (2.0b4). I often have more than one nagios "root" process (launched by the root process), and sometimes have a "defunct" nagios process. It is really anoying, as it can leads to Nagios not working any more, or, at best, only doing half of the checks it should perform,... Often, it also stops recording the results of the checks, or "forget" latest informations after a restart, rolling back to the status data of hours ago. I don't remember doing any big change lately, so I can't find why I am facing all those problems right now... Does any of you know what can cause those defunct processes, or the multiple nagios "root" processes? Or best do you know how I could avoid it :) Thanks a lot for your help, Johan. --- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.

[Nagios-users] Cgi configuration : possible to set "authorized_for_..." to all but one user?
Hello everyone, Up to now, everyone who had an access to my nagios webpages could execute commands. So, the cgi.cfg file had things like : authorized_for_all_service_commands=* I would like to add a new user who can only see the informations, but could not execute any command. I tried the following : authorized_for_all_service_commands=*,!new_username But it did not work. Do any of you know if there is a way to do this?

Re: [Nagios-users] multiple contact notifications for one host
If I understand well, you want your check_disk on HostA to be send to the 2 mailing lists, while all the other check_disk being only send to one of the mailing list? If I am true, then you could create a new service, "check_disk_A", doing exactly the same things than the regular check_disk, but with other notification options.

I am not sure about it, but I think that recoveries are only send to contacts who received the alert.

Re: [Nagios-users] Problem with nagios NRPE
Hello, I might be wrong, but I think that there is no definition of "check_fw1" in the nrpe.cfg (or in the included files) on your new server. So, NRPE doesn't know what to do when it receives the "check_fw1" instruction. There should be something like that : command[check_fw1]= Johan Corsini.
