在Observium中添加主机(无法Ping)

Question

我在CentOS 6.5上使用Observium v0.14.4。配置一切正常，我正在成功访问该软件(我正在使用HTTPS进行web访问)。我正在按照RHEL/CentOS 1可用的说明进行操作。

我正在尝试添加一个主机(“贝多芬”)，它可以通过从Observium机器(“mozart”)执行ping和fping命令来查看：

[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

但是，当我尝试使用sudo ./add_device.php beethoven.example.com example v2c添加贝多芬时，我得到：

Try to add beethoven.example.com:
Could not ping beethoven.example.com.
Devices skipped: 1.

谷歌和DDG没有透露任何有用的解决方案。谢谢!

Answer 1

我遇到了同样的问题，当我检查ping代码时，这是因为它在/usr/bin中查找fping，而我的fping安装在/usr/sbin中，所以我只是这样做了

ln -s /usr/sbin/fping /usr/bin/fping

您可以通过取消注释includes/functions.php中的619行来启用ping调试

$ping_debug = TRUE; $file = '/tmp/pings_debug.log'; $time = date('Y-m-d H:i:s', time()); /// Uncomment this line for DEBUG isPingable()

它显示了这个日志

# cat pings_debug.log
2014-08-02 10:16:43 | PING ERROR: firewall (1) | FPING OUT: sh: /usr/bin/fping: No such file or directory
2014-08-02 10:16:43 | PING ERROR: firewall (2) | FPING OUT: sh: /usr/bin/fping: No such file or directory

与其使用符号链接(这可能会导致发行版的包管理器出现问题)，不如尝试编辑工具的Observium配置和设置路径。

查看此处：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";
