I am using Observium v0.14.4 on CentOS 6.5. Everything is good to go with configuration and I am successfully accessing the software (I'm using HTTPS for web access). I am following the directions available for RHEL/CentOS [1].
I am attempting to add a host ("beethoven") that is visible via ping and fping from the Observium machine ("mozart"):
[user@mozart observium]$ sudo fping beethoven.example.com
beethoven.example.com is alive
[user@mozart observium]$ sudo ping -c2 beethoven.example.com
... (this works) ...
2 packets transmitted, 2 received, 0% packet loss, time 1001ms
However, when I attempt to add beethoven using sudo ./add_device.php beethoven.example.com example v2c I get:
Try to add beethoven.example.com:
Could not ping beethoven.example.com.
Devices skipped: 1.
Google and DDG don't reveal any helpful solutions. Thanks!
I had the same issue and when I checked the ping code it's because it was looking for fping in /usr/bin and my fping was installed into /usr/sbin so I just did
ln -s /usr/sbin/fping /usr/bin/fping
You can enable ping debugging by un-commenting line 619 in includes/functions.php
$ping_debug = TRUE; $file = '/tmp/pings_debug.log'; $time = date('Y-m-d H:i:s', time()); /// Uncomment this line for DEBUG isPingable()
which showed this log
# cat pings_debug.log
