Adding Host in Observium (Cannot Ping)

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!

Check if you have snmp installed, I know it sounds dumb, but it happened to me, and after apt install snmp, problem was resolved.

Rather than symlinking (which can cause issues with your distribution's package manager) try editing your Observium config and settings paths for the tools.

See here : Observium : Location Of Executables

$config['rrdtool']        = "/usr/bin/rrdtool";
$config['fping']          = "/usr/bin/fping";
$config['fping6']         = "/usr/bin/fping6";
$config['snmpwalk']       = "/usr/bin/snmpwalk";
$config['snmpget']        = "/usr/bin/snmpget";
$config['snmpbulkwalk']   = "/usr/bin/snmpbulkwalk";
$config['whois']          = "/usr/bin/whois";
$config['ping']           = "/bin/ping";
$config['mtr']            = "/usr/bin/mtr";
$config['nmap']           = "/usr/bin/nmap";
$config['nagios_plugins'] = "/usr/lib/nagios/plugins";
$config['ipmitool']       = "/usr/bin/ipmitool";
$config['virsh']          = "/usr/bin/virsh";

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
