Hello and thanks for accepting my account subscription for this forum. This is my first post here.
I'm quite new to Icinga2 so maybe my problem is quite trivial to someone who's already reached guru level Anyway, I've been searching the internet for a while to help me out but I didn't succeed. Neither have I been able to find any post addressing my problem by using the forum search. So I thought I'd better ask for a hint:
To get familiar with the software I'm running a fresh Icinga2 (r2.6.2-1) on Ubuntu 16.04.2 LTS. This machine is a satellite installation and receives its config from a master (v2.6.2 on CentOS 7). The only piece of configuration which applies to its zone is one Linux host to monitor with nothing more but hostalive.
This results in 2 tests carried out for this host right out of the box with no further configuration:
- PING OK - Packet loss = 0%, RTA = 40.67 ms
- SSH OK - OpenSSH_6.6.1p1 Ubuntu-2ubuntu2.7 (protocol 2.0)
What looks very strange to me is the host status, which is:
CRITICAL - Network Unreachable (fqdn.of.host)
As far as I understood from the documentation, hostalive uses a ping to determine if a host is up or down.
So why is this host displayed as down while ping is successful?
Since my setup is as it came out of the box I hope someone here can quite easily explain to me what I did wrong or how I can track this issue down to its roots.
