Re: [Nagios-users] Remote event handlers using NRPE
You could create an NRPE command who's sole purpose is to restart a single service, that way all you do is call the command and it restarts the service. Though yes, if you have lots of services to restart then you are going to have to configure lots of separate NRPE commands.

Is there any solution for this dilemma? Can I have Nagios monitor hosts without reporting them as down when they are down? I know this may sound strange, but I would like to have statistics about how long the machines have been up and when. Marc, we use action handler scripts to schedule downtime in this case. As an example, a downtime for a service is scheduled for 6 minutes if $1 is CRITICAL and $2 is HARD. That is the maximum amount of time this service needs to be restarted (via nrpe, in the same script): /usr/bin/printf [%lu] SCHEDULE_SVC_DOWNTIME;host5.example.com;Host5;`date +%s`;$((`date +%s` + 6 * 60));1;0;0;serveradmin;Service on Host5 is restarted\n `date +%s` /var/spool/nagios/nagios.cmd Following http://old.nagios.org/developerinfo/externalcommands/commandlist.php, you can send the command DEL_SVC_DOWNTIME if the service is up before the scheduled downtime ends. The same should be possible with SCHEDULE_HOST_DOWNTIME or SCHEDULE_HOST_SVC_DOWNTIME and DEL_HOST_DOWNTIME. So Nagios will still see the downtime, but since it is marked as scheduled downtime, your statistics may look better ;-) HTH Werner - -- -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.18 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://www.enigmail.net/ iEYEARECAAYFAlA/SnEACgkQk33Krq8b42NDRACaA1Gr5NS/FqWEWaP/qrb/ST6k HocAni3ka4fC+tilNYBefzlz0IFAsDT7 =fZIL -END PGP SIGNATURE- -- 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.

[Nagios-users] Custom Remote Commands
Hi There Just was wondering if there is a way to customize the list of host commands list that are shown on the right column when you click on a host. There you can see, show the host in the map, send custom host notification. I'd like to add something like, reboot the server for example, that would be very usefull, maybe someone manage to do this this way or another. The problem is when the server is not accessible over ssh but pingable, so I guess that with can use ipmi, or fired reboot command by other means. Any thought on this are appreciated.

[Nagios-users] Heads up for config changes in Nagios 4
Currently, with Nagios 3, it's possible to have cyclic group includes,
like this:
define hostgroup{
hostgroup_name HG1
alias Hostgroup 1
hostgroup_members HG3
}
define hostgroup{
hostgroup_name HG2
alias Hostgroup 2
hostgroup_members HG1
}
define hostgroup{
hostgroup_name HG3
alias Hostgroup 3
hostgroup_members HG2
}
With Nagios 4, that will generate an error. Currently the behaviour
is that the first hostgroup, as determined by alphabetical sorting,
will get the members of its included groups, but the later ones in
the sorting will not get the members of the previous ones, which is
surprising to say the least.
This will work the same for all grouptypes.

[Nagios-users] Include extra information on service alert
Hello Mdadm on one specific host has been reporting failed disks, and falling over to the spare. I get an event notification when this happens (Nagios no longer sees 2 devices in the U state), but I would like to include the output of cat /proc/mdstat with the email notification. I am thinking that the best approach is to write a custom notification command to include this data, but I'm not sure if there are already hooks for this already. I am using Nagios within OMD and CheckMK.

And you didn't post your linux-server template config so you will have to check your and retry_interval definition.
