Hi Kevin,
Zenoss, like most network monitors lives and breathes SNMP. So, you
gotta get SNMP turned on and working for Zenoss to do most of what it
does. Zenoss has some capabilities without SNMP, but a usable SNMP
configuration gets you much farther.
So, is SNMP working? Can you, from the command line, walk the device
and see the values you want to monitor? You don't really need to be an
expert, just do a quick scan:
$ snmpwalk -c <community> -v 1 <other device> | wc -l
If the result is less than 100, or you get an error, then SNMP isn't
working with that community string. You could have the wrong community
string, the device may not allow scanning from your address, you may not
have all the SNMP MIBs turned on. On my Ubuntu development laptop, I
get back 2400 values.
Once you are confident that SNMP is turned out, and providing the values
Zenoss is looking for, you have to configure Zenoss to use the right
community strings. You may want to use SNMPv2 for some devices that
support it. You will have to install SNMP Informant on Windows boxes if
you want to use the default Zenoss configuration.
Once you have configured devices that support SNMP, you can move on to
the devices monitored through commands.
Can you run the plugins manually as Zenoss? Assuming your apache is at
remote.apache.loc:
$ /usr/bin/zenplugin.py apache remote.apache.loc
Have you configured apache to have mod_status turned on? Can you
navigate to the url http://remote.apache.loc/server-status? Yes, we
know the docs need to be better. See:

OK,
I'm going to try to reach out one more time before I scrap this thing.
I've installed zenoss per the directions. It's graphing devices, but for
some reason some things just aren't working right.
From the directions I have read, if I poll a device that has an ethernet
connection, it should create that device and start graphing the device.
Ethernet, cpu, etc... whatever. But I seem to be having some problems.
First, the apache plugin isn't working correctly. I'm not able to graph
anything apache.
Second, on my Windows, Linux, and Cisco devices I have no network graphs.
Any help appreciated.
Thanks.
Kevin
