[collectd] ping plugin problem

[Piotr Kaczmarek]

Hello, i have problem with ping plugin when pinging many hosts.
192.168.100.199 is the host where collectd is running.

With this plugin configuration:

<Plugin ping>
Host 192.168.100.199
</Plugin>

everything seems fine:

Jul 15 19:15:26 slupno collectd[13218]: ping plugin: host =  
192.168.100.199, latency = 0.392000
Jul 15 19:15:36 slupno collectd[13218]: ping plugin: host =  
192.168.100.199, latency = 1.018000
Jul 15 19:15:46 slupno collectd[13218]: ping plugin: host =  
192.168.100.199, latency = 1.190000
Jul 15 19:15:56 slupno collectd[13218]: ping plugin: host =  
192.168.100.199, latency = 1.134000
Jul 15 19:16:06 slupno collectd[13218]: ping plugin: host =  
192.168.100.199, latency = 0.662000
Jul 15 19:16:16 slupno collectd[13218]: ping plugin: host =  
192.168.100.199, latency = 0.939000
Jul 15 19:16:26 slupno collectd[13218]: ping plugin: host =  
192.168.100.199, latency = 38.491000
Jul 15 19:16:36 slupno collectd[13218]: ping plugin: host =  
192.168.100.199, latency = 0.655000
Jul 15 19:16:46 slupno collectd[13218]: ping plugin: host =  
192.168.100.199, latency = 0.947000
Jul 15 19:16:56 slupno collectd[13218]: ping plugin: host =  
192.168.100.199, latency = 1.789000

38 is odd, but other times are good.

When i added some hsots to ping plugin:

<Plugin ping>
Host 192.168.100.21
Host 192.168.100.22
Host 192.168.100.23
Host 192.168.100.24
Host 192.168.100.25
Host 192.168.100.26
Host 192.168.100.27
Host 192.168.100.28
Host 192.168.100.29
Host 192.168.100.31
Host 192.168.100.32
Host 192.168.100.33
Host 192.168.100.34
Host 192.168.100.35
Host 192.168.100.199
</Plugin>

debug returns very high latency (which i'm sure is not true) localhost  
(192.168.100.199)

Any ideas why it ping plugin shows wrong, high values, and how to get  
it working properly when having many hosts to ping?

Thanks in advance.

Cheers,
