Icinga check_ssh tries 127.0.0.1:22 and I want to use network IP and alternative port

vars.port = host.vars.ssh_port

should be

vars.ssh_port = host.vars.ssh_port

but is not needed anyway as it is already defined at your host object.

Defining vars.ssh_address = host.address will be overwritten by

vars.ssh_address = “$check_address$”

and is also not needed.

Makes a lot of sense, however it still tries to go to 127.0.0.1 and port 22. How i do the manual check the alert is fixed for a couple of minutes and then comes back.

In theory this should be enough:

apply Service "ssh" {
  import "generic-service"

  check_command = "ssh"

  assign where host.address
}

And in a host definition:

object Endpoint "host.foo.bar" {
    host = "10.10.10.xx"
}

object Host "host.foo.bar"  {
    import "generic-host"

    address = "10.10.10.xx"
   
    vars.os = "FreeBSD"
    vars.ssh_port = 4545
}

object Zone "host.foo.bar" {
    endpoints = [ "host.foo.bar", ]
    parent = "master"
}

You can check the executed command by using inspect in icingaweb.

I don’t find the inspect option under the service details. I go to problems → service problems. Click on ssh problem on a host and then I have the details. There is where it supposes to be? I thought it should be under Problem handling. Is this the place? Do I have a miss-configuration?

@rsx

BTW: Every zone and endpoint object needs to be defined since V2.11 in zones.conf only.

I suffer that several months ago. However, I did find something that might be an issue. Not sure with this issue, but might be a general problem. I share here just in case.

The file host.conf is under zones.d, and it seems not to be process. I copy it to conf.d, as I see in the documentation that it should be there. However it breaks things, this is the content of the file, which I believe is the standard configuration. This is the hosts.conf file:

/*
 * Host definitions with object attributes
 * used for apply rules for Service, Notification,
 * Dependency and ScheduledDowntime objects.
 *
 * Tip: Use `icinga2 object list --type Host` to
 * list all host objects after running
 * configuration validation (`icinga2 daemon -C`).
 */

/*
 * This is an example host based on your
 * local host's FQDN. Specify the NodeName
 * constant in `constants.conf` or use your
 * own description, e.g. "db-host-1".
 */

object Host NodeName {
  /* Import the default host template defined in `templates.conf`. */
  import "generic-host"

  /* Specify the address attributes for checks e.g. `ssh` or `http`. */
  address = "127.0.0.1"
  address6 = "::1"

  /* Set custom variable `os` for hostgroup assignment in `groups.conf`. */
  vars.os = "FreeBSD"

  /* Define http vhost attributes for service apply rules in `services.conf`. */
  vars.http_vhosts["http"] = {
    http_uri = "/"
  }
  /* Uncomment if you've sucessfully installed Icinga Web 2. */
  //vars.http_vhosts["Icinga Web 2"] = {
  //  http_uri = "/icingaweb2"
  //}

  /* Define disks and attributes for service apply rules in `services.conf`. */
  vars.disks["disk"] = {
    /* No parameters. */
  }
  vars.disks["disk /"] = {
    disk_partitions = "/"
  }

  /* Define notification mail attributes for notification apply rules in `notifications.conf`. */
  vars.notification["mail"] = {
    /* The UserGroup `icingaadmins` is defined in `users.conf`. */
    groups = [ "icingaadmins" ]
  }
}

I get configuration errors related to the master server:

[2020-08-21 16:10:58 +0000] critical/config: Error: Validation failed for object 'master.foo.bar!ssh' of type 'Service'; Attribute 'command_endpoint': Checkable with command endpoint requires a zone. Please check the troubleshooting documentation.

Thanks a lot.
