Re:

[Martin Pala]

Hi,

fixed the problem in the development version, will be part of next Monit release (5.12.2). It will be possible to use both network check types:

check network virtnetw with address 1.2.3.4 # where 1.2.3.4 is IP alias

or:

check network virtnetw with interface "eth0:0" 

Best regards,

Martin

Hi Martin,

Sorry but using the ip address results in the same error message:

[CET Mar 18 14:16:26] error    : 'virtnetw' link data gathering failed -- Cannot read /sys/class/net/eth0:0/operstate -- No such file or directory

Based on:

check network virtnetw with address 1.2.3.4

Groeten,

Martin

Thank you for making this clear. The HWaddr is the same on both ethernet adapters so I used the IP address instead.

Thanks again!

The virtual interface (IP alias) doesn't have it's own network statistics ... it's part of the parent interface (eth0), we currently don't support using interface names like "eth0:0".

You can set the IP address-based monitoring for IP alias, but it'll read the statistics of the parent interface too - for example:

--8<--
eth1:0    Link encap:Ethernet  HWaddr 00:22:33:44:55:66
          inet addr:192.168.1.100  Bcast:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
--8<--

can be monitored by:

--8<--
check network myipalias with address 192.168.1.100  # note: will find interface for 192.168.1.100, which is eth1 in this case
--8<--

or:

--8<--
check network mynet with interface eth1  # note: statistics include the interface itself and all its IP aliases
--8<--


Best regards,
Martin
