core/v2/handlers
NOTE: Requests to core/v2/handlers
API endpoints require you to authenticate with a Sensu API key or access token.
The code examples in this document use the environment variable $SENSU_API_KEY
to represent a valid API key in API requests.
Get all handlers
The /handlers
API endpoint provides HTTP GET access to handler data.
Example
The following example demonstrates a GET request to the /handlers
API endpoint:
curl -X GET \
http://127.0.0.1:8080/api/core/v2/namespaces/default/handlers \
-H "Authorization: Key $SENSU_API_KEY"
The request results in a successful HTTP/1.1 200 OK
response and a JSON array that contains the handler definitions in the default
namespace:
[
{
"metadata": {
"name": "influx-db",
"namespace": "default",
"created_by": "admin"
},
"type": "pipe",
"command": "sensu-influxdb-handler -d sensu",

},
{

Get a specific handler
The /handlers/:handler
API endpoint provides HTTP GET access to handler data for specific :handler
definitions, by handler name.
Example
The following example queries the /handlers/:handler
API endpoint for the :handler
named slack
:
curl -X GET \
http://127.0.0.1:8080/api/core/v2/namespaces/default/handlers/slack \
-H "Authorization: Key $SENSU_API_KEY"
The request will return a successful HTTP/1.1 200 OK
response and a JSON map that contains the requested :handler
definition (in this example, slack
):
{
"metadata": {
"name": "slack",
"namespace": "default",
"created_by": "admin",
"labels": null,
"annotations": null
},
"command": "sensu-slack-handler --channel '#monitoring'",
"env_vars": [
"SLACK_WEBHOOK_URL=https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX"
],

],
"handlers": [],

Create or update a handler
The /handlers/:handler
API endpoint provides HTTP PUT access to create or update a specific :handler
definition, by handler name.
Example
In the following example, an HTTP PUT request is submitted to the /handlers/:handler
API endpoint to create the handler influx-db
:
curl -X PUT \
-H "Authorization: Key $SENSU_API_KEY" \
-H 'Content-Type: application/json' \
-d '{
"metadata": {
"name": "influx-db",
"namespace": "default",
"labels": null,
"annotations": null
},
"command": "sensu-influxdb-handler -d sensu",
"env_vars": [
"INFLUXDB_ADDR=http://influxdb.default.svc.cluster.local:8086",
"INFLUXDB_USER=sensu",
"INFLUXDB_PASSWORD=password"
],
"filters": [],
"handlers": [],
"runtime_assets": ["sensu/sensu-influxdb-handler"],
"timeout": 0,
"type": "pipe"
}' \
http://127.0.0.1:8080/api/core/v2/namespaces/default/handlers/influx-db
The request will return a successful HTTP/1.1 201 Created
response.

Update a handler with PATCH
The /handlers/:handler
API endpoint provides HTTP PATCH access to update :handler
definitions, specified by handler name.
NOTE: You cannot change a resource’s name
or namespace
with a PATCH request.
Use a PUT request instead.
Also, you cannot add elements to an array with a PATCH request — you must replace the entire array.
Example
In the following example, an HTTP PATCH request is submitted to the /handlers/:handler
API endpoint to update the filters array for the influx-db
handler, resulting in an HTTP/1.1 200 OK
response and the updated handler definition.
We support JSON merge patches, so you must set the Content-Type
header to application/merge-patch+json
for PATCH requests.
curl -X PATCH \
-H "Authorization: Key $SENSU_API_KEY" \
-H 'Content-Type: application/merge-patch+json' \
-d '{
"filters": [
"us-west",
"is_incident"
]
}' \
http://127.0.0.1:8080/api/core/v2/namespaces/default/handlers/influx-db
API Specification
/handlers/:handler (PATCH) | |
---|---|

Delete a handler
The /handlers/:handler
API endpoint provides HTTP DELETE access to delete a handler from Sensu (specified by the handler name).
Example
The following example shows a request to the /handlers/:handler
API endpoint to delete the handler slack
, which will result in a successful HTTP/1.1 204 No Content
response.
curl -X DELETE \
http://127.0.0.1:8080/api/core/v2/namespaces/default/handlers/slack \
-H "Authorization: Key $SENSU_API_KEY"
API Specification
/handlers/:handler (DELETE) | |
---|---|
description | Removes the specified handler from Sensu. |
example url | http://hostname:8080/api/core/v2/namespaces/default/handlers/slack |

Get a subset of handlers with response filtering
The /handlers
API endpoint supports response filtering for a subset of handler data based on labels and the following fields:
handler.name
handler.namespace
handler.filters
handler.handlers
handler.mutator
handler.type
Example
The following example demonstrates a request to the /handlers
API endpoint with response filtering for only handler definitions in the default
namespace and whose filters include state_change_only
:
curl -H "Authorization: Key $SENSU_API_KEY" http://127.0.0.1:8080/api/core/v2/handlers -G \
--data-urlencode 'fieldSelector=state_change_only in handler.filters && handler.namespace == default'
The example request will result in a successful HTTP/1.1 200 OK
response and a JSON array that contains only handler definitions in the default
namespace and whose filters include state_change_only
:
[
{
"metadata": {
"name": "slack",
"namespace": "default",
"created_by": "admin"
},
"type": "pipe",
"command": "sensu-slack-handler --channel '#monitoring'",
"timeout": 0,
"handlers": null,
"filters": [
"state_change_only"
],
"env_vars": null,
"runtime_assets": [
"sensu-slack-handler"
],
"secrets": [
{
"name": "SLACK_WEBHOOK_URL",
"secret": "slack_webhook_url"
}
]
}
]
NOTE: Read API response filtering for more filter statement examples that demonstrate how to filter responses using different operators with label and field selectors.
