Interest was expressed about my interface report which creates an output much like that of the interfaces utilization report found under performance reports. Corrections, comments, suggestions and otherwise are welcome. Have fun.

Create the two files below. One is a plugin [interfaceerrs.py] which gathers the data points (in/out errors in this case), the second is the report [Interface_Errors.rpt] which uses the plugin to populate the screen.

_______[/opt/zenoss/Products/ZenReports/plugins/interfaceerrs.py]
import Globals
from Products.ZenReports import Utils, Utilization
import re

class interfaceerrs:
"The interface error report"

def run(self, dmd, args):
summary = Utilization.getSummaryArgs(dmd, args)
report = []
for d in Utilization.filteredDevices(dmd, args):

isLocal = re.compile(d.zLocalInterfaceNames)
for i in d.os.interfaces():
if isLocal.match(i.name()): continue
if not i.monitored(): continue
if i.snmpIgnore(): continue
if not i.speed: continue

results = i.getRRDValues(['ifInErrors',
'ifOutErrors'],
**summary)
inerror = results.get('ifInErrors',
results.get('ifInErrors', None))
outerror = results.get('ifOutErrors',
results.get('ifOutErrors', None))

r = Utils.Record(device=d,
interface=i,
speed=i.speed,
inerror=inerror,
outerror=outerror)
report.append(r)
return report

Once the two files are created, execute as zenoss user 'python /opt/zenoss/Products/ZenReports/ReportLoader.py --force' to install the rpt [Interface_Errors.rpt]. You'll likely need to restart zenoss to cycle the reportserver (if anyone knows how to restart the report server please post it.) This is needed so it can find the new plugin [interfaceerrs.py].

Please post your results, or let me know if you have any trouble.

BTW, I developed the report for Zenoss 2.4.1 / 2.4.2, so if you have 2.4 or higher you should be good.
