ubuntu14.04 monitoring with zenoss 4.2.3

Hi,

im using zenoss 4.2.3 to monitor our infrastructure.

Recently we started to use ubuntu14.04 and we started to encounters several issues with these servers.

1. Disk space readings is incorrect. Im aware that there is 5% that ext saves but we had an issue with one server that zenoss show only 25% disk util when df show 95%.

2. I've switched to collect the disk data using ssh instead of SNMP and from time to time fre bytes becoming "unknown" and its causing strange alerts, i have open alerts for disk with 138% disk util.

3. Network graphs are incomplete, like it failed to collect the data from time to time.

I dont see any of these issues on other servers in our environmentand this is really frustrating.

Is anyone havingthese issues as well

Thanks in advance,

Ronny
