I'm using youtube data API at Google Cloud Console.
I want to send slack to my channel if it's quota exceed 90% of quota limit per day. (900) By setting Alert policy at Monitoring Tab
I want to know setting an alert policy and sending alert is free or paid?
At some Google monitoring document it costs by metric but I'm confused.
On
for gist understanding
setting an alert policy and sending alerts in google cloud monitoring as of now is a free feature.and so you can use it to send alert but there may be costs associated with the usage of the YouTube Data API itself follow youtube/v3/determine_quota_cost and if you you are using stackdriver then please tack a look at stackdriver/pricing
to understand the pricing please try to understand information given below also follow the given refs. for better details
Cloud Monitoring
Monitoring charges for the following:
Metrics measured by bytes ingested, when the ingested metric data exceeds the free monthly metric allotment.
*Non-chargeable metrics don't count towards the allotment limit.
*Metrics measured by number of samples ingested.
*Cloud Monitoring API read calls that exceed the free monthly API allotment.
*Monitoring API write calls don't count towards the allotment limit.
*Execution of uptime checks.
*Execution of synthetic monitors.

Non-chargeable metrics
Metric data from Google Cloud, GKE Enterprise, and Knative isn't chargeable. Non-chargeable (free) metrics include the following:
Google Cloud metrics. For additional information, see Footnote 2.
GKE Enterprise metrics. For additional information, see Footnote 2.
Istio metrics
Knative metrics
Google Kubernetes Engine system metrics

Chargeable metrics
All metric data, except for those metrics listed in the section titled Non-chargeable metrics, is chargeable. Most metric ingestion is charged by the number of bytes, but some is charged by the number of samples; these pricing models are described in the following sections.
The following factors contribute to ingestion costs:
The type of data points—scalar values or distribution values—collected by the metrics. For information about the data type associated with a specific metric type, see the list of metrics. For information about scalar and distribution data types, see Value types.
The number of data points written to time series. This value depends on the frequency with which the data is sampled and the cardinality of your data. The cardinality determines how many time series are generated for a combination of metric and monitored-resource types; for more information, see Cardinality.
The values for the metric and resource labels that are part of your time series don't contribute to your charges.

Setting up an alert policy and sending alerts using Google Cloud Monitoring is free. As confirmed in the documentation for both metric-based & log-based alerting policies, there are no costs associated with using alerting policies.
Cost might come from the use of notification channels such as pub/sub notification channels. For example, Custom metrics are charged based on the number of data points collected. Check Chargeable metrics and Cloud Monitoring pricing summary for more information.
In addition to that, writing a metric produces costs If it's a custom metric. Standard metrics are free of charge.
If you want to know how much a metric costs you basically have to calculate from the price, most likely with Google Cloud pricing calculator.
Important is how often the metrics get written. One example for 2000 custom metrics:
once a minute = 134 Dollar
every 30 sec = 306 Dollar
every 5 sec = 2030 Dollar
