Interesting one.  If you have the chargeable product then Impact may be able to do that for you.

If you are on Zenoss Core, given that you have a small number of devices to correlate, you may be able to do something useful with a transform. 

In the following example, I have a transform on /Status/Ping that just tests for events from one test device - zenny1.class.example.org.  I have a list, pingDevs, of the other relevant devices.  The pingStatus is checked for each of my pingDevs and, if greater than 0 (where 0 is good), increase a count and add the offending device to the downDevs list.  I then amend the existing event if my count is >=2, adding the other down devices to the event summary.

 

if device.titleOrId() == 'zenny1.class.example.org' and evt.severity > 0:
pingDevs = ['zenny1.class.example.org', 'zenny2.class.example.org', 'lotschy.skills-1st.co.uk']
count = 0
downDevs = []
for pName in pingDevs:
pDev = dmd.Devices.findDevice(pName)
if pDev.getPingStatus() != 0:
count +=1
downDevs.append(pName)
if count >= 2:
evt.severity = 5   # Critical
otherString = ' '.join(downDevs)
evt.summary = evt.summary + '  ' + otherString + '  also down.'

No guarantees but, as a quick test, it worked for me.

Cheers,

Jane

Thanks! That looks promising, but its somewhat limited to the list of devices I enter in the "pingDevs" array. I'm curious if there is a way to search the Zenoss DB for all devices of a particular class or grouping, etc., so I can then create such an array dynamically?

Sure. To get all devices under the /Ping device class using zendmd:

>>> for pDev in dmd.Devices.Ping.getSubDevices():
...   print pDev.id
...
10.191.0.191
192.168.2.1
deodar-mgt.skills-1st.co.uk
group-100-b1.class.example.org
group-100-b2.class.example.org
group-100-c1.class.example.org
group-100-c2.class.example.org
group-100-c3.class.example.org

You can put whatever class you like so /Server/Microsoft/Windows/Taplow would be:

for pDev in dmd.Devices.Server.Microsoft.Windows.Taplow.getSubDevices

 

"pDev" in this case would be the object representing the device and pDev.id is it's unique identifier key (of type string).

In this case, in the transform above, you would not need the line:

pDev = dmd.Devices.findDevice(pName)    as that starts with the id in pName.

So...

for pDev in dmd.Devices.Ping.getSubDevices():
if pDev.getPingStatus() != 0:
count +=1
downDevs.append(pName)

 

and so on.

Cheers,

Jane
