Hi,
We are wanting to use transforms to suppress events based on the device status. One example of this is sometime events come through for SNMP being down, when the whole device is actually down
In the transform if we use
device.getPingStatus()
When an event comes in and the transform runs it is throwing:
ZepConnectionError: Could not connect to service.
The strange part is if we manually run "zeneventd run" it runs through fine without throwing any exceptions
Full example of transform:
#Suppress events if the device is not pingable
if getattr(evt, 'severity', 0) > 0 and getattr(evt, 'eventClass', '/Unknown') == '/Status/Snmp':
ping_state = device.getPingStatus()
mydedupid = "%s|%s|%s|%s|%s" % (evt.device,evt.component,evt.eventClass,evt.severity,evt.summary)
evt.dedupid = mydedupid #Keep dedupid id the same (changing summary affects it)
if ping_state > 0:
#suppress
evt.eventState = 2
evt.summary += " (down)"
elif evt.eventState == 2:
#unsuppress event if previously supressed and now is up
evt.eventState = 0
Running Zenoss Core 5.0.9. We were previously on 5.0.6 and have just upgraded to try and resolve the issue but it is still there
Any clues would be greatly appreciated!
Thanks

Had a better look at this and the issue appears to be that zeneventd can't access port 8084 (from zeneventserver)
I am guess this is by design in the new version of zenoss with docker
Is there any an alternative way of running device.getPingStatus() now from a transform rule
Alternatively how can you forward 8084 from the zeneventserver service to zeneventd service
# serviced service attach zeneventd
[root@400866192eb3 /]# netstat -lpnt

I got around this by linking 8084 from zeneventserver to zeneventd
edit eventd service
# serviced service edit eventd
added the following under Endpoints
{
"Name": "zep",
"Purpose": "import",
"Protocol": "tcp",
"PortNumber": 8084,
"PortTemplate": "",
"VirtualAddress": "",
"Application": "zep",
"ApplicationTemplate": "",
"AddressConfig": {
"Port": 0,
"Protocol": ""
},
"VHosts": null
},
restart eventd for it to apply
# serviced service restart eventd

Hello,
I'm having a similar problem where I cannot get a "real" value for getPingStatus(). When I call it, it returns 0 always, suggesting the device is up, when it is not. Wondering if I'm having the same issue you were having and I'm trying to figure out what file you edited to allow you to add the endpoint.
It looks like you have a serviced commmand somewhere, and I don't have that... If you could let me know what file holds the Endpoints, that would be a great help.
Thanks.
Paul
