Hi,
recently I came up with zenoss 3 to 5.0. I tried to use the same transforms as in 3 versions zenoss. But none of them no longer works. What is the problem Changed syntax
Two examples of transforms:
In triggers action command -curl --data 'chat_id='xxxx --data-urlencode 'text=''{"${device/summary}", "${device/Location}", "${device/SnmpLocation}", "${device/message}", "${device/firstTime}"}' 'https://api.telegram.org/xxxx/sendMessage'
And transform for link down/up events:
import re device = dmd.Devices.findDevice(evt.device) index = getattr(evt, 'ifIndex', 0) descr = getattr(evt, 'ifDescr', '') evt.component = descr evt.deviceSnmpLocation = device.snmpLocation evt.deviceName = device.titleOrId() if device: description = '' for iface in device.os.interfaces(): if index and iface.ifindex == index: descr = iface.description elif descr and iface.name == descr: descr = iface.description int = getattr(evt, 'component', '') evt.summary = "Port " + int + " is down!" evt.message = "Port " + int + " is down!"

I've found transforms are flaked in 5.0, especially when using the "Reclassify an event" button in the main Event console....especially when using the "Reclassify an Event" button in the main console. Try updating to 5.1; I've found that transforms are more reliable in that version than in 5.0 for us.

If you continue to see issues in 5.1 please report each as a bug. Thanks!

I fixed the problem with a transform link down / up. it works
But the problem with the trigger command using Curlremains.
Now there was another problem. In zenoss 3I created a custom datapointand draw a graph, as a result of this setting I could use a transform in the form device.getRRDValue ( 'name'). InZenoss 5 rrdis not used. How, then use these custom parameters(datapoints) in the transforms

I would like to know as well if the syntax of device.getRRDValue has changed for 5.x since RRD is no longer the database used. Is the old RRD syntax still in use or was it replaced by something else

I found in Zenoss 5.0 how to get a custom setting getRRDValuesin zendmd. But it does not work intransforms.Inthe logsI seethis error:

Everyone,
It's not working in the transforms because the transforms are running in a container that doesn't have the neccesarry endpoint access to hit the datastorage backend. Technically it's possible to adjust the zeneventd template definition to grant it the correct endpoint access. Email me if you're interested in that.
Generally speaking it's not a good idea to grab metric data in a transform. While it does work please use extra case. It really can dramatically tie up the system at the worst of times. :)
If anyone needs custom development or consulting don't hesitate to reach out!
Take care!
