Nagios Support Forum

1.) I just installed NCPA on a couple more servers(OH THANK YOU LORD!) and neither of them are actually communicating back to my server. The only difference I see is on the one test box(my laptop) that is working there is a trailing slash on the NRDP url(i.e. http://servername/nrdp/) but the other two servers do not have the trailing slash. Is that the cause of my issue, if not, any hints of what to look at? I can login to the agent remotely, so it is running.

2.) How do most people handle HOSTS in passive environments? Do I just assume it is up, or do I do some sort of passive check that will mark the host as up in Nagios and then have a check freshness on hosts so if I don't get that passive check I get alerted that the host is down?

Also....

3.) When looking in the web interface I see "None" in the config name and I know we entered a config name during install. We entered the FQDN of the server in the hostname field and the config name field(these servers will have checks specific to just them). So it looks like something wasn't written properly.

1) Very possibly, last I tried you NEED the trailing /, and the installer should not allow you to pass go and collect your installed files unless that path is valid.

2) This is a pretty broad one and as you might expect depends on the admin and choice of installation. You could absolutely just expect they are up and only do freshness with the services. I would probably look into having my central ncpa forwarder do active checks on the end passive agents and forward them as a host check(if possible), or setup individual host passive checks. I just like having that additional control of not getting millions of notifications if and when freshness goes out the window.

3) I feel like this was an issue that was recently fixed, but will have to confirm with Nick. What version are you presently running?

1.) I'm going to modify and add the slash and see if that fixes it, if so, I'll file a bug report since the installer let me proceed without it.

2.) Ugh (lol)

3.) The latest, freshly downloaded from the link in the docs

1) sounds like a plan.
2) .... yup
3) OK I'll take a look and confirm. I suppose I should verify, active NCPA checks, passive via nrdp protocol, or nrds configs?

1.) fixed by adding the / to the URL in the config file, so the installer is not properly verifying the URL!

3.) In the config file the "Config Name" is set, but it is showing in the web ui as none. I have another test to perform to see if I can resolve it. I'll get to that as I can, just wanted to let you know about #1

Cool, I will talk with Nick about both and see what ideas he has. Let me know what you come up with for #3 and I will discuss any additional notes you have with him then.
