HTTP - CRITICAL - Socket timeout after 10 seconds

[xxxvii]

I have a situation where I'm monitoring both the HTTP and HTTPS services on a host. For some reason which I'm finding hard to explain, the HTTP service is returning the following error: "CRITICAL - Socket timeout after 10 seconds." The HTTPS service, however, is reporting OK.

Based on a few posts in this forum, I tried extending the timeout period to 20, 30, even 60 seconds (e.g., -t 60) in my service definition, but I kept getting the socket timeout message. When I tried setting it to 120 seconds, the error persisted, but with this new message: "Service check timed out after 60.03 seconds."

Curiously, I'm also monitoring a specific web page, using the check_http command too, and that one is reporting OK.

Below you'll find snippets of my original code. If you need anything else, let me know. Thanks!

For the check on the HTTP host/service, try dropping the '-S' from the check command so it looks like this

Code: Select all

check_http! -H oururl.com -u "/xxx-yyy/aaa-bbb.page?execution=e1s1"

Do this manually from the CLI 1st, before editing the corresponding file.

Thanks, but that is not the service definition that's causing the issue, but rather this one:

Code: Select all

define service{
        use                     generic-service         ; Inherit default value$
        hostgroups              web-hosts-pub
        servicegroups           webservices
        service_description     HTTP
        check_command           check_http! -H $HOSTADDRESS$ -I $HOSTADDRESS$ -e HTTP/1.
        }

For the check on the HTTP host/service, try dropping the '-S' from the check command so it looks like this

Code: Select all

check_http! -H oururl.com -u "/xxx-yyy/aaa-bbb.page?execution=e1s1"

As a follow-up to my previous post, I decided to try this just for kicks and now I am getting the "CRITICAL - Socket timeout after 10 seconds" status for this service as well; just by removing the -S.

So, to reiterate, HTTPS checks work fine, but HTTP checks don't.

Can you post the command definition for check_http in your environment? You may be passing -H twice, which is causing an issue.

From the CLI, can you run /usr/local/nagios/libexec/check_http -H oururl.com -u "/xxx-yyy/aaa-bbb.page?execution=e1s1" and get a proper result?
