Nagios Support Forum

I've got a strange issue here. In my host status summary block I've got 1 host that is down. If I click on that one it brings up the (attached screenshot) list where I would expect that host to be listed. The list is, however, empty. I cleared browser cache and things like that, didn't help.

Further info
- There is a host that is down
- Clicking on the "228" that are up I get a list that I'd expect showing all the hosts that are up

Are there service assigned to this host? The link will keep you on the Service Status page and you'll see this behavior if there are no services on the host. You should see the host and any services assigned it if you go to Home > Details > Host Status, and click on the down link in the Host Status Summary table.

Good morning and thank you for the reply. Sounds like a bug to me, why would clicking on a HOST down notification take me to a SERVICE status page? If I go to the host group summary and click on the down host quantity I get a list of HOSTS filtered by down (for that group). Seems my original issue should send to a list of all HOSTS filtered by down, no?

To answer your other question, no, I do not have additional services associated with many of my hosts. There's a ping service built into setting up the host and this SHOULD be considered a service, especially if it is going to go red and indicate a state change, etc. Why would I set up a redundant "Ping" service to do the same thing?

This is intended functionality, the developers have stated that this is the way it's supposed to work.

If you go to Home > Host Status and click the Host Status Summary links from that page it will list the Hosts.

If you go to Home > Service Status and click the Host Status Summary links from that page it will list the Services.

I have a workaround, I'll post it shortly.

Actually, what version of XI are you running so I can get you the proper version of the file? You can grab the version from the bottom left hand side of the web interface.

FWIW - I don't call saying a bug is a feature a valid response I'd love to hear the reasoning behind this here "feature"

Sounds like a bug to me, why would clicking on a HOST down notification take me to a SERVICE status page?

It would depend on what page you are on, prior to clicking on any of the "Host Status Summary" links. This is "by design". There is no design that is "perfect" - trust me. We've been discussing many different scenarios, related to this particular issue in the past. Here's the logic (as of now):

1. If you were on the "Host Status" page (Home > Details > Host Status), you would be mostly interested in seeing the hosts' status.
- Clicking on any of the links under the "Host Status Summary" section will give you information about hosts, that are Up, Down, Unreachable, etc..
- Clicking on any of the links under the "Service Status Summary" section will give you information on which hosts have services is particular state - OK, Warning, Critical, etc.

2. If you were on the "Service Status" page (Home > Details > Service Status), you would be mostly interested in seeing the services' status.
- Clicking on any of the links under the "Host Status Summary" section will give you information about services, that are on hosts in Up, Down, Unreachable, etc. state. As we are looking into services info (we are on the "Service Status" page), clicking on a host will NOT show you anything if there are no services added to this particular host.
- Clicking on any of the links under the "Service Status Summary" section will give you information on (display) all services is particular state - OK, Warning, Critical, etc.

There's a ping service built into setting up the host and this SHOULD be considered a service, especially if it is going to go red and indicate a state change, etc. Why would I set up a redundant "Ping" service to do the same thing?

Having an extra Ping service is somewhat redundant - I agree with you on that. However, there are some "use cases". For example, you may want to create a service dependency and only run/notify on a service that is dependent on the "Ping" check for a specific host. Nagios is a very flexible product, and most of the time, you need to modify the "defaults" as they don't make sense for each environment.

I hope this helps. Thank you!

Agree 100% I've been in large scale software development for a long long time

1. If you were on the "Host Status" page (Home > Details > Host Status), you would be mostly interested in seeing the hosts' status.
(a) Clicking on any of the links under the "Host Status Summary" section will give you information about hosts, that are Up, Down, Unreachable, etc..
(b) Clicking on any of the links under the "Service Status Summary" section will give you information on which hosts have services is particular state OK, Warning, Critical, etc.

Bingo! This is NOT the current behavior. If I click on a link from the Host Status Summary section I am not presented with Host Status information. What you describe in 1a is expected behavior. What happens is 1a and 1b function the same, they both follow the 1b path.
"bug"

That said, I think your information might have helped me find the issue. I added the "Host Status Summary" box to my dashboard from the Service Status page. Adding that element to my dashboard from the Host Status page produces the desired behavior.

Product suggestion - update the UI to make these things more visually discernible to decrease confusion.
