Hi Dickson I've had a similar problem with a Cisco ASA and I've just tested again with a PIX firewall on the vm appliance. Zenoss tries to optimize the SNMP mechanism by querying a number of OID's on a single UDP packet. Currently, the maximum is set to 40 which overflows the SNMP buffer on these devices.
The solution is to lower this parameter which I've done by changing the following 2 files: $ZENNHOME/Products/ZenRRD/zenprocess.py (line 47) $ZENNHOME/Products/ZenRRD/zenperfsnmp.py (line 39) to the following: MAX_OIDS_PER_REQUEST = 20 # (instead of 40...) Don't forget to restart zenperfsnmp after changing these files. Unfortunately, I've got to change this every time I upgrade Zenoss... The Cisco firewalls seem to be the only devices with this problem. Hope this helps, antonio -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dickson Law Sent: Friday, December 29, 2006 9:17 AM To: [email protected] Subject: [zenoss-users] Spaces in the interface name Hi all I was adding a cisco pix to zenoss and all look fine. however the name of the interface has space in it and therefore the directory created for performance graphing also contain spaces (e.g. PIX Firewall 'outside' interface).
