Pieter,

Ooh! I like that toggle, as I have the same issue when an NFS host is down... snmp blocks on the disk free stats for NFS. Thanks for the pointer!

All,

I worked out what is causing the problem: NFS shares!

The server has _NFS shares_ which are located on the workstation which is shutdown. As soon as the workstation is down,**the 1st *snmpwalk* will not complete and timeout somewhere halfway. Any subsequent *snmpwalk* commands will give a timeout straightaway. This explains why there is no data recorded until the workstation is up again. At that point, the_NFS shares _are restored and *snmpwalk* will successfully run.

To fix this problem I have added the following line in my */etc/snmp/snmpd.conf*:

*skipNFSInHostResources true*

After restarting the SNMPD service NFS shares are exclude and observium is recording the server details while the workstation is down.

Cheers,

Pieter

Hi,

I recently installed Observium CE and noticed some very weird behavior.

Observium monitors currently 3 devices: 1 Debian Server + 1 Debian workstation + 1 Ubuntu workstation. The Debian workstation is shutdown overnight and rebooted in the morning, nicely shown in the Event logging:

Shutdown: *<date time> System Device status changed to Down (ping)* Reboot: *<date time> System Device status changed to Up <date time> Reboot Device rebooted after

<hours min sec> * That's all fine. But now the weird thing is that for the Server the Event log says almost at the same time:

*<date time> System Device status changed to Down (snmp)*

and when the workstation is rebooted, the Server Event log says at almost the same time:

*<date time> System Device status changed to Up*

Graphs for the server don't get updated/have data for the time the Debian workstation is down. The Ubuntu workstation runs 24/7 and graphs get properly updated during time the Debian workstation is down.

I would expect that what happened with the workstation should have no effect on the data collection of the Server.

Details:

Observium CE    0.14.4.5229
OS                        Debian 7    (Server + Workstation)
                             Ubuntu 10.40 LTS (Workstation 24/7)

How do I get this working properly?

Thanx,

Pieter
