It is a valid JSON file with a valid syntax.
If the file contains APM schema with no UIM metrics.
The schema root node is also the probe name that can contain only lowercase characters, numbers, hyphen, or underscore
The schema root node name is the same as the name attribute in the definition section of the schema ($.name = $.{name}.definition.name)

Log in to UMP and navigate to
Groups
,
Operating System
,
Robot
where you deployed the custom probe.
Click the
Monitoring
tab and view the custom probe.
For example, using the default schema you can create a custom probe to monitor elasticsearch servers.

As a Tenant Administrator, log into UMP and navigate to
Groups
,
Operating System
,
Robot
and then click the
Monitoring
tab.
Select and expand the node for the custom probe and create the profile.

Navigate further to a sub-profile and activate or deactivate the required metrics.

To enable threshold alarms, configure the
policy_mode_enabled
parameter in the MCS configuration file and set the value as
false
. For more information about configuring alarm thresholds, see Configuring Alarm Thresholds in MCS. Alternatively, you can create alarm policies and can configure thresholds from the Operator Console.
Navigate to the
Inventory
, search for the hostname that you define dwhile creating the profile, and then click on the
Metrics
tab
to view the metrics collection and to view alarms, click
Alarms
tab.
View Metrics

In the
metrics
section of the schema, define only one value for the following attributes:
operator
and
severity
. These attributes do not support an array of values.
Or
Remove the following attributes from the
metrics
section in the schema:
thresholdenabled
;
operator
;
severity
;
custom_message
;
custom_clear_message

If the status that the QOS_HTTP_STATUS returns is 200. If not, verify the logs to troubleshoot.
Using the REST Client verify that the endpoint is reachable and returns the expected response.
If the calculated_method attribute is required with a QoS definition to publish a derived metric value from a raw value.
