Event fields are described in Event Fields Zenoss documentation topic.

zenoss.event

zenoss.event sends an event to Zenos. It has the following arguments:

Name	Type	Description	Default value
url	string	Zenoss events endpoint URL.
username	string	HTTP BASIC authentication username.	"" (no auth)
password	string	HTTP BASIC authentication username.	"" (no auth)
action	string	Router name.	"EventsRouter"
method	string	Router method	"add_event"
type	string	Event type	"rpc"
tid	int	Temporary request transaction ID	1
summary	string	Event summary	""
device	string	Related device	""
component	string	Related component	""
severity	string	Event severity
eventClass	string	Event class	""
eventClassKey	string	Event class key	""
collector	string	Collector
message	string	Related message

Supported severity values are: "Critical", "Warning", "Info", "Clear".

Example:

import "contrib/bonitoo-io/zenoss"
import "influxdata/influxdb/secrets"
import "strings"

username = secrets.get(key: "ZENOSS_USERNAME")
password = secrets.get(key: "ZENOSS_PASSWORD")

lastReported =
  from(bucket: "example-bucket")
    |> range(start: -1m)
    |> filter(fn: (r) => r._measurement == "cpu" and r._field == "usage_idle")
    |> last()
    |> tableFind(fn: (key) => true)
    |> getRecord(idx: 0)

zenoss.event(
    url: "https://tenant.zenoss.io:8080/zport/dmd/evconsole_router",
    username: username,
    username: password,
    device: lastReported.host,
    component: "CPU",
    eventClass: "/App,
    severity:
        if lastReported._value < 1.0 then "Critical"
        else if lastReported._value < 5.0 then "Warning"
        else "Info",
)

zenoss.endpoint

zenoss.endpoint creates a factory function that creates a target function for pipeline |> to send event to Zenoss for each row.

Name	Type	Description	Default value
url	string	Zenoss events endpoint URL.
username	string	HTTP BASIC authentication username.
password	string	HTTP BASIC authentication username.
action	string	Router name.	"EventsRouter"
method	string	Router method	"add_event"
type	string	Event type	"rpc"
tid	int	Temporary request transaction ID	1

The returned factory function accepts a mapFn parameter. The mapFn accepts a row and returns a record with the following events fields:

Name	Type	Description
summary	string	Event summary
device	string	Related device
component	string	Related component
severity	string	Event severity
eventClass	string	Event class
eventClassKey	string	Event class key
collector	string	Collector
message	string	Related message

Example:

import "contrib/bonitoo-io/zenoss"
import "influxdata/influxdb/secrets"
import "strings"

username = secrets.get(key: "ZENOSS_USERNAME")
password = secrets.get(key: "ZENOSS_PASSWORD")

endpoint = zenoss.endpoint(
    url: "https://tenant.zenoss.io:8080/zport/dmd/evconsole_router",
    username: username,
    username: password
)

from(bucket: "example-bucket")
  |> range(start: -1m)
  |> filter(fn: (r) => r._measurement == "cpu" and r._field == "usage_idle")
  |> last()
  |> endpoint(mapFn: (r) => ({
      device: lastReported.host,
      component: "CPU",
      eventClass: "/App,
      severity:
          if r._value < 1.0 then "Critical"
          else if r._value < 5.0 then "Warning"
          else "Info",
    })
  )()
