For the record, the only way I found out how to make this work, was to
make servicecheck_id not unique, but still a key.
Due to the number of servicechecks one might have, I have my doubts
whether that could be a problem, can anyone tell me he knows for sure it
is a problem?

Re: [Nagios-users] Nagios authentication thru LDAP.
Qua, 2011-08-10 às 13:42 -0400, Terry Carmen escreveu: Quoting Robert J Molerio rjm...@nyu.edu: Can anyone indicate how this can be done? We would like users to log on to Nagios via LDAP. I think we need to configure the Apache server within Nagios to be able to do this but we're not sure. It's definitely possible using Apache's LDAP auth, however you might want to consider that when your network is going ape, it's really nice to know that your Nagios machine doesn't require any external resources. That's why I chose local auth (htpasswd). Now matter how much of the brown stuff is flying around, Nagios is up. Terry Tsk tsk tsk. Apache supports falling back to other auth methods and you should use Nagios and LDAP via SSL sockets (https and ldaps) securing passwords. Setting up Apache against LDAP is really easy, and most of the LDAP issues are on its maintenance rather than pointing at it for data.

Re: [Nagios-users] Nagios alert via Twitter - authorization issue
That will not work anymore because Twitter is run by idiots who think
Oauth is the be all end all of security. It isn't.
It is perhaps a good compromise if you don't want to give your user and
password to a foreign website in order to have it do things on your
behalf but for local applications it actually *reduces* security by
imposing a more complicated method than http basic auth via https (BTW,
you should use https with basic auth always, and not http as you have)
full weird workflows.
I suggest the following:
1) create an account in https://identi.ca/ (a Free Software social
network)
2) use your command with the following difference in the url:
https://identi.ca/api/statuses/update.json
(they have a compatible api).

When using passive checks, you *should* do the following:
define service {

enabled
passive_checks_enabled 1 ; Passive service checks are
enabled/accepted
parallelize_check 1 ;

retain_nonstatus_information0 ; Retain non-status information

max_check_attempts 2
normal_check_interval 5
retry_check_interval1
contact_groups admins
notification_interval 0
notification_period 24x7
notification_optionsw,u,c,r
}
Notice in particular check_freshness and freshness_threshold!
Now on a service you have:
define service {
