run "vmstat 1" and check the "wa" column (should be 3rd column in from the
right). It should show your %i/o wait every second. It's shown above, but
only for one period in time. If your i/o wait is staying relatively low (low
single digits), then it's likely not a disk i/o problem on that server. Your
%0.01 shown above is nothing....but the server could have just been between
polling for that moment.
Before doing too much tweaking of zope, I'd try and clean it up and re-index.
This is what I do as the zenoss user (note, the spacing is important)
# zendmd
Code:
# Fix deviceSearch
brains = dmd.Devices.deviceSearch()
for d in brains:
try:
bah = d.getObject()
except Exception:
print "Removing non-existent device from deviceSearch: " + d.getPath()
dmd.Devices.deviceSearch.uncatalog_object(d.getPath())
commit()
# Fix componentSearch
brains = dmd.Devices.componentSearch()
for d in brains:
try:
bah = d.getObject()
except Exception:
print "Removing non-existent device from componentSearch: " +
d.getPath()
dmd.Devices.componentSearch.uncatalog_object(d.getPath())
commit()
dmd.Devices.reIndex()
commit()
reindex()
commit()
[/code]
